Developer’s Success Story – A Solar Integrated Green Roof in NE DC

By Lisa Walsh | Commercial Solar Developer | Solar Energy Services, Inc.

For the newly-finished Taylor Street Storage facility in North East DC, a 17,500 square foot green roof with fully integrated solar panel array that showcase a value-stacked, elegant design providing both a cost-effective solution to storm-water management. All without forfeiting the solar panels that generate income via federal tax incentives and DC’s superb solar production-based financial incentives.


With over three million square feet of green roofs in Washington DC and 50MW+ of solar installations – the City is no stranger to either technology. However, the integration of both on the same roof is less common, despite the symbiotic relationship between the two offering a number of advantages.

Storm-water Management


Approval for a commercial building permit in Washington DC must include a storm-water management plan as defined by DC’s Department of Energy and the Environment (DOEE). For Taylor St, the Development team could have chosen between:

  1. Lost parking spaces to house costly underground containers for capturing and storing runoff
  2. Payment of ever-increasing storm-water management fees
  3. Implementation of a multi-layered Green Roof to treat 100% of the rainfall obligation with a perennial, sedum based plant surface – as per DOEE requirements.
    The green roof offered a cost-effective storm-water management solution that required no additions or demo’s to the existing structure.

Most savvy developers realize that an empty roof in Washington DC is money left on the table. With the best solar financial incentives in the USA, the payback is rapid followed by years of production-based paydays. Small wonder that the development team at Taylor Street were interested if – and how – a solar array could integrate with a Green Roof. The good news is not only does the solar system seamlessly integrate with the green roof but the relationship is one of symbiosis and cost-effectiveness. Here’s why:

BALLAST. Most solar systems installed on DC’s commercial flat roof areas are ballasted. i.e. an assortment of concrete blocks, along with the weight of the solar panels and racking, is engineered to hold down the weight of the array with minimal or no penetrations to the roof membrane.
With close to 35 PSF of weight, a green roof more-than provides this ballast negating the need for concrete blocks or supplemental attachments. This is worth mentioning as the Green Roof is now a fully engineered component of the solar system bringing the question of tax credit eligibility into play. Is the Green Roof, or portion of, now eligible for the 30% Federal Tax Credit? Certainly worth conferring with a tax adviser.

A close up of the Solar System mounted into the soil on the roof.

CREATION OF A MICRO-CLIMATE: Furbish designs their perennially healthy green roofs with a wide palette of sedum species. These drought-resistant succulants require little maintenance and have varying requirements for daily sunlight – from full-sun to all-shade. Contrary to first impressions the intermittent shading and weather protection provided by the solar panels provide a micro-climate highly conducive to the plants underneath, in between and around the solar arrays.

DESIGN: Most ballasted solar systems have ample aisles between each row of solar panels insuring that each solar panel is optimized and avoiding shading from the panel row in front. Solar panels can also be tilted anywhere between 5 and 35 degrees. This is adjusted to account for shading, panel count and orientation considerations. This flexibility of design was helpful for integration the green roof. Aisle spacing, solar panel size and tilt were designed with the Green roof in mind – not only as it relates to healthy plants, but also for annual maintenance access requirements.

Established Example featuring similar product and design as Taylor Street


CHALLENGES: Solar-integrated green roofs are not as common as their singular counterparts. Fair to say this project did not come without some challenges


DOEE DESIGN STANDARDS: Department of Energy and Environment is responsible for DC’s Stormwater Management and insuring all DC buildings comply with runoff standards. The burden was on SES and Furbish to ensure that the solar arrays were not going to impede the ability of the plants to thrive and provide the necessary water retention requirements. The design and permitting side of the project insofar as panel tilt, aisle spacing and racking integration were designed in collaboration with DOEE.


INSTALLATION TIMELINES: Furbish Company are Green Roof specialist, Solar Energy Services, Inc. are solar specialists. Integrating these technologies took heightened coordination between our installation teams, mostly in terms of labor efficiency, communication and timeliness. The latter was particularly stringent as the Certificate of Occupancy, required to meet the developer’s lease requirements, was contingent upon the completion of the Green Roof which now included solar racking, wiring and panel installations. Throw in some PEPCO Permission to Install challenges related to the solar portion, and the pressure was on.


The project came with some unusual PEPCO interconnection timing challenges at the end. Ironically not related to the Green Roof aspect of the application. Nonetheless, this system is now outputting electricity like gangbusters. All’s well that’s ends well.

Maryland Solar – Ready to Grow Again

For many years, Maryland has been a leader in solar policy and solar deployment.  In the last 3 years, we’ve fallen behind other states, watching our robust growth give way to several years of decline.  It’s almost hard to believe, but Maryland has been losing solar jobs for more than two years after peaking at approximately 5300 in late 2016.

Policy Clouds

Why is this happening?  One of the biggest reasons is the value of the state solar production incentive, the SREC (Solar Renewable Energy Certificate).  Those of you who own solar or have considered buying solar are probably all too familiar with SREC pricing.  Because Maryland property owners adopted so much solar in the first half of the decade, we outpaced the state’s goals, depressing the value of the market-based SREC incentive.  This was a good problem for the industry to have until it became clear that our goal (25% renewables by 2025 with 2.5% solar by 2022) was clearly not aggressive enough.

The Time is Now

We are now at a time of severe urgency for the Maryland solar industry.  With installations on the decline for over two years and job losses mounting, we are losing a trained employment base and leaving federal tax benefits on the table.   The solar industry has been working with other coalition members (wind industry, environmental organizations, etc.) for a few years to try to increase the state’s Renewable Portfolio Standard (RPS), but have been hampered by the Hogan Administration’s reluctance to incentivize more renewables until the completed RPS Study Report is released.  The study was due to be released in December of 2018, but has been delayed and some fear this is intended to stall an RPS increase for another year.  We cannot wait.

Governor Hogan has gone on record with his desire to fight climate change.  He recently coauthored an OpEd in the Washington Post with Virginia’s Democratic Governor, Ralph Northam to emphasize the urgency and the need for bipartisan solutions to climate change.  It is in this bipartisan spirit that we hope to see the Hogan Administration support the Maryland General Assembly in passing the Clean Energy Jobs Act
(CEJA)(SB0516, HB1158) of 2019 that will increase our renewable energy goal to 50% and the solar portion to 14.7 %. “Click here to read more about this

No-Brainer Investment for Maryland

One of the primary arguments against increasing the RPS has to do with the impact on utility ratepayers.  The preliminary indication is that the increased renewable goals associated with the CEJA will add approximately $1.85/mo. to the average electricity bill.  While this is not insignificant, it is important to note that a 2018 Daymark study, commissioned by the Hogan Administration’s Public Service Commission, found that for every $1.00 of investment in solar, we return approximately $5.00 in economic and health benefits to the state.   Solar jobs are good jobs that pay well, representing a path to economic stability for many installers.  And best of all, solar installation jobs cannot be exported.

We need YOUR help

As a solar advocate, we ask that you commit to express your support for CEJA in the Maryland legislative session this year.  The bill has been submitted and we should have a bill number shortly.  In the meantime, please continue to advocate for more solar whenever you can and be prepared to contact your Maryland state legislators to support this important legislation when the time comes.  Stay tuned for a special email notification with the bill number, and suggested talking points in the coming weeks.

Solar is Booming in Washington DC

Washington DC has been a leader in solar development for many years.  In the last 12 years, DC legislators have set aggressive targets, helped to streamline solar permitting, introduced a solar access rights law, and passed a landmark community solar bill to increase access to solar for those without an available sunny rooftop.   Many of these policies include mechanisms to help bring the benefits of solar to communities of low and moderate income.  The collaboration between the solar industry and DC policymakers has helped to build a robust market where solar installations are happening throughout the city, from downtown office buildings to churches, warehouses and residential rooftops across the city.   These policies and the resulting private investments are creating good jobs in the District and reduced energy costs for many of its residents.

Double Down

Since solar and clean energy have been delivering in DC, the stakeholders decided they wanted a more ambitious goal.  In the summer of 2018 the District started on a path to double down with their commitment to renewable energy by proposing the most aggressive renewable energy target in the country when compared to other state policies.  The new goal calls for 100% clean energy (5.5% solar) by the year 2032, with 10% solar by 2041.  Hawaii and California are the only other states that have 100% goals, but both of those targets are positioned for 2045, quite a few years later than DC. 

Other Benefits of the legislation

In addition to doubling the renewable energy target, the proposed legislation would provide a few more benefits to solar advocates.  The bill:

  1. Limits geographic eligibility over time to concentrate the solar development in the District or on the District’s grid
  2. Pulls the current solar carve-out schedule forward by two years to increase SREC demand
  3. Extends the solar carve-out from 5.5% in 2032 to 10% by 2041
  4. Addresses specifics about previously contracted (“grandfathered”) load that is exempted from the newest RPS
  5. Includes transparency requirements on the energy suppliers to provide insight into the exempted load and associated time periods
  6. Modifies Alternative Compliance Payment (ACP) schedules to require $300 ACPs through 2041
  7. Increases the shelf-life of an SREC from three to five years, increasing SREC price liquidity and stability.
  8. Introduces various reporting requirements on the Public Service Commission in order to keep the Council and the Public apprised of the progress of renewable energy development.

We’re in the Home Stretch

The Clean Energy DC Omnibus Amendment Act of 2018 was introduced in July 2018 and made its way through the Council over the fall with hearings and two unanimous votes of support on November 27th and December 18th.  In January, the bill was submitted to Mayor Bowser for her signature and she obliged on January 18thClick here to read the bill“.   The remaining hurdle is for approval by the US Congress within 30 legislative days.  The only way that Congress can stop this legislation is with a joint resolution and the President’s signature.  As a result, passage into law is considered by most to be inevitable and in fact we are seeing market pricing for SRECs responding accordingly.

Thank your Legislators

So now that the law is almost passed, it is time to prepare to deliver.  The industry has a lot of solar to build and we’re working hard at that.  As a solar advocate who cares about renewable energy in DC, please consider taking a few moments to call or write to your Councilmember to thank them for their support of Clean Energy DC Omnibus Amendment Act of 2018.  It’s always important to show our gratitude.

Thank you for your support of solar!

Buy American and Save

For the month of February SES is offering $1000 off of any solar system that includes US Manufactured Panels.  That’s right, support US manufacturing and Save!  All you have to do is reference this offer during or before your site visit.

Here’s 5 More Reasons Why:

1.    Provides Jobs

The Solar Industry’s growth and inherent job creation is no secret, we are leading the pack among every other industry nationwide. Most of these jobs are being created on the installation side, but we also need to support the rest of the value chain.

2.    American Independence Includes Energy Independence

We as Americans have pride in our nation and in our independence. By generating our energy locally, with renewable resources, and US products, we strengthen our country and our independence, both individually and collectively as Americans.

3.    Do It for The Environment

Current technologies allow manufacturers in the US to support a greener, cleaner solar manufacturing process. If we invest in American-made products, we strengthen our manufacturing base, support US jobs, while insuring  that we are doing our part to contribute to a cleaner environment for ourselves, and the generations to come. Also, by reducing the need to ship overseas, the net carbon footprint is much lower

4.    We Control Labor Standards, They Don’t

The US is a leader in fair labor and safety standards. With minimum wage and safety regulations in the workplace being upheld, you can be sure that your panels are made by people who are being supported and treated fairly in the workplace.

5.    Guaranteed Quality of Goods

The term “Made in the USA” speaks of quality, excellent craftsmanship and a superior product. With a lower cost of labor abroad, many factories rely on fabrication and assembly processes by hand. This introduces higher rates of  failure when compared to the American Standard of automated soldering and assembly. While panel quality continues to improve in the aggregate, US products remain the leaders in quality and performance.  Price tags are slightly higher for Made in USA products, but you find true value among longevity and performance.

Solar Plus Storage is Ready for Prime-Time Backup Power for your Home

As we’ve seen the cost of solar drop rapidly in the last ten years (more than 80%), we continued to endure those naysayers in the distance arguing that “no matter how cheap you make solar; much like wind, it will never dominate the energy landscape because of intermittency.” It’s hard to believe people still say “Never” in the context of technology? That term only provokes our great American drive and ingenuity, which continues to deliver. Witness electric storage costs have dropped 80% in the last eight years, outpacing the dramatic solar cost reductions!

Battery technology today

Today, electric batteries continue to back up solar in more and more markets every year. Batteries are giving solar system owners a lot more control and choice about energy independence, while giving grid operators a game changing tool to help manage the modern grid with greater economic efficiency. We’ll talk more about the how and why, later in this post.

Storage market is heating up

So far SES has contracted for 7 battery installs already this year in Maryland, up dramatically from 2017. The residential solar plus storage market has begun to take off in many markets. In fact, the preferred battery suppliers were out of stock for more than 4 months this year, both from increased demand to complement solar projects, but also due to the soaring demand increase for Electric Vehicles (EVs) that use the same battery technologies.

Storage is like bacon

Why is storage so valuable? One of my favorite energy experts, Katherine Hamilton (https://38northsolutions.com/team/bios/) once said that “storage is like bacon, it makes everything better.” Storage has almost a dozen value streams that can be monetized now or in the future. The two biggest and most obvious value streams are that it can provide extra capacity in times of high demand, and it can provide extra demand in times of excess capacity. In both cases, it provides stabilizing value to the grid and more efficient use of generating assets.

A testament to the value of storage on the grid was seen several years ago when the California Public Utilities Commission required utilities to procure a minimum amount of storage. Not only did the major utilities comply, they all procured more storage than mandated. They are well aware, storage helps them modulate an increasingly dynamic and decentralized grid.

Residential Solar Panels Anne Arundel County MD

Why should I consider solar plus storage for my home?

If you deploy solar along with your energy storage solution, you can utilize the same federal tax benefits as you do for solar, namely the 30% investment tax credit. In Maryland, you are eligible for an income tax credit on the storage portion of the system, in addition to the other state solar incentives (https://energy.maryland.gov/business/Pages/EnergyStorage.aspx). As a result, the economics in Maryland for residential solar + storage are much improved from a few years ago.

The main reason our residential customers are deploying energy storage is for backup power during a grid outage. This is typically done by way of an essential loads subpanel in their electric system. SES often installs these subpanels as part of our solar + storage project.

Another factor driving this trend is a residential customer’s desire to position themselves to cut the cord in the future, if the utility relationship becomes unappealing or uneconomical for them.

Lastly, future changes to electric rate design and/or net metering policy, could present solar + storage owners the ability to increase their savings or even generate revenue from the services that their frequently-idle storage can provide.

Are you building a new home and want to be sure it is ready for the energy architecture of the future? It’s easier than you think. Ask your builder or electrician to insure you have an essential loads subpanel (to use with electric battery storage, or possibly a generator). Secondly, request they install an empty (capped) electrical conduit from attic to electric room for us to easily add your solar energy conducting wire in the future.

Please see Roger Perry’s technical writeup on residential storage applications recently implemented by SES.

What has brought about this market opportunity?

Electric storage has long been an essential part of any true off-grid solar/wind application and this is where the earliest developments have taken place. As solar began to penetrate the grid in the last 10 years, there has been a lot of R&D investment in this future “holy grail” of renewable energy development. The investment is now paying off.

Storage broke into the US grid-tied market about five years ago. In the case of Hawaii, it was mostly a market driven change. Extremely expensive power, a grid congested with rapid solar growth, denials and delays of solar interconnection applications, and abundant sunshine, all contributed to the new paradigm. This resulted in economics that justified a certain segment of residential customers in Hawaii to cut the cord and embrace storage as a long-term solution. This sent an alarming message to utilities around the world: You better embrace these changes or plan to go the way of the buggy whip!

At about the same time, California’s PUC mandated a specific quantity of storage on the grid, much of it behind the meter. The utilities went on to exceed that mandate in the first auction and later in 2017, the target was increased again, with little to no resistance. In the past year, we’ve seen California utilities choose new battery storage over new gas fired peaker plants to meet peak loads in three separate cases. This is a tremendous validation of the economics of storage, particularly in an age of record low natural gas prices.

What’s ahead for energy storage?

The horse is out of the barn. Distributed energy generation combined with storage, will be the foundation of the future electric grid. The role that storage will play in this transformation will be enormous at the macro level, but somewhat uncertain at the micro level due to regulatory policy, incentives, and local market conditions.

We should expect to see strong storage growth in markets with the following attributes:

  • Places where local or state incentives are promoting storage – Maryland is one of them.
  • Markets where system owners can capture supplemental revenue from their storage investments (Our grid operator, PJM has piloted bundling distributed storage as a revenue generating resource for storage system owners)
  • Markets with high electric rates or Time of Use (TOU) rates.
  • Markets where electric “demand charges” represent a large cost for commercial and industrial (C&I) customers. This is because storage can dramatically lower a building’s electricity demand profile, and thus add energy bill relief to a portion of the bill where solar has had limited impact.
  • Microgrids are increasingly popular, particularly with campus style environments and military installations. These applications will increase storage demand and further drive down costs through scale and experience.

Next steps

Be sure to contact SES if you are interested in solar + storage. We will be happy to design a system that is customized to your needs. As always, we’ll provide you all the support you need to capture the Maryland solar grant and the storage tax credit (which has a limited budget) so contact us right away.

Practical Considerations for a Battery System

As long as I’ve been doing solar, people have been asking about batteries. The response has always been “yes, we can do them, but it will cost a lot”. That usually ended the conversation.

One question to ask is “why do you want batteries?” Do you lose power frequently? If not, a portable generator will keep your refrigerator, freezer, computers, tv and some lights going. Downsides are; noise, fumes, refueling, having to run extension cords to where needed and putting everything away when power comes back. Not too bad once in a while and it’s very cost effective. Just hope you aren’t out of town when power goes out. There is nothing automatic about this set-up.

If you lose power often and don’t want to do the portable generator dance every few months, you can get a permanently installed generator with automatic start. These are close to $5000 installed for the ones that will run most of your house when the power goes out (a larger one can be installed for a few thousand more that will run everything). This is what hospitals and critical buildings use. Power goes out, the generator starts automatically and powers the house with only a momentary loss of electricity.

Downsides? Noisy, they need maintenance and, if propane or diesel powered, they need the fuel tanks to be kept filled.

What if you lose power often, don’t want the noise, maintenance and fuel expense of a generator? What if you want a system that is environmentally friendly, will turn on automatically, is silent, will run pretty much nonstop without refueling? You should look into installing a battery back-up system connected with a solar system.

What are the downsides? Well, cost is one. While not as expensive as in years past, battery back-up systems are still costly. Compared to a permanently installed generator, battery backups tend to run few thousand more. Ask your accountant but you may be able to take the 30% solar tax credit on the additional cost of the batteries. This brings the price in line with a generator.

Another downside is you can’t run everything in your house. Things a battery cannot run for any length of time are air conditioners or heat pumps, electric water heaters, electric dryer or electric ranges. What they can run are gas or solar water heaters, gas or oil boilers, refrigerators, freezers, lights, tvs, computers, fans and pretty much everything else. Well pumps are on the edge depending on how efficient they are. While running a modern variable speed well pump is not an issue, older well pumps require a large startup current which can be too much for the battery to handle. We are about to install a “soft start” control to try and reduce a well pumps surge demand for one of our customers but the jury is still out.

We are now installing LG Chem lithium Ion batteries. LI batteries have a lot of advantages over the old lead acid batteries. The big advantage they have is they are not damaged by running them dead, whereas lead acid batteries do not like being discharged to less than 50% of charge, a Lithium Ion battery will give you it’s full rating. The one we use is rated for 10 Kilowatthour (KWH). A lead acid battery would need to be rated at 20 KHW to achieve the same capacity. Lithium batteries are also much lighter (not that the customer will have to move them) and can be charged much faster.

The big downsize of LI batteries is the upfront cost compared to LA but they will last much, much longer and they are maintenance free.

In a future blog I will discuss the two different ways to interface a solar system with the batteries, AC coupled and DC coupled and the pros and cons of each as well as what a 10 KWH battery will give you as far as run times for various appliances. I’ll also talk about how a battery system can be retrofitted to your existing solar system.

Solar Systems with Integrated Electric Vehicle Chargers

….like Peas and Carrots

Solar Panel, Solar energy, Annapolis MDAs referenced in our accompanying EV Growth Blogs, the adoption of Electric Vehicles has skyrocketed in recent years. This is small wonder considering EV purchasers can look forward to a 30% federal tax credit on the upfront cost, reduction of fuel costs of at least 60% (according to this Nissan Leaf owner’s calculations), and State Grants/tax credits where applicable (Maryland, for example) and the negation of various oil changes and maintenance costs that accompany an internal combustion engine. For homeowners who have discovered the substantial energy savings by purchasing (not leasing!) a solar residential system, it’s a natural step to want to extend these savings to their current, or future, electrified vehicle.

Ahead of the curve on this natural progression is an innovative new product from inverter manufacturer SolarEdge. All solar systems have two major components 1. Solar panel arrays 2. Inverter(s) that convert incoming DC energy to appliance-ready AC energy. As the national leader in residential inverter supply, SolarEdge made a great move in developing an Inverter that has a built-in EV Charger with a 25’ charge connector. Net energy meter customers (NEM) or energy generating customers interconnected to Pepco are not eligible to apply for the R-PIV rate.

Electric Charging,Solar, Annapolis MD

Why not choose a separate EV Charger?

Four reasons:

  1. Cost. Upgrading to an inverter that has a built-in EV Car Charger comes at around a $1000 cost increase (assuming one inverter/car charger). However, this upgrade – as part of the solar installation – qualifies for the 30% federal tax credit, putting the material cost at around the same as a separate stand-alone EV Charger such as Clipper City. In addition, the integrated inverter has no additional labor or electrician charges – its all covered in the solar install.
  2. Warranty. Popular stand-alone Car Chargers such as Clipper City come with a 3- year warranty. Solar Edge’s integrated inverter has a 12-year warranty, with upgrades up to 25 years available.
  3. Design Elegance. Between service panels, routers, generators and other wall-mounted electronics – its nice to have a 2-in-1 solution and save some wall space. No additional wiring or conduits needed. Of course, the inverter does need to be placed within 25’ of where the EV will be parked nightly.
  4. All Pros no Cons. As with Stand-alone chargers, Solar Edge’s integrated solution allows for indoor/outdoor placement, comes with a 25’ connector and offers software that tracks your EV’s energy consumption that is accessible from desktop or phone, and can be controlled remotely.

Thinking Ahead

Due to the clear advantages, and seeming inevitability of rapid EV adoption by the majority of Americans by the Year 2030, we now ask all of our prospective solar shoppers two questions:

  1. “Do you plan to buy an Electric Vehicle in the not-so-distant future?”
  2. If so, “ What is your expected weekly/annual mileage?”

Mileage calculations inform how many solar panels we should add to the array in order to cover as much EV car use as possible (as roof space allows). Worth noting for our Washington DC/Montgomery County solar customers, PEPCO does require us to fill out an Electrical Usage Calculation Sheet if the solar system is sized over 120% larger than the past 12 months usage history. In those cases we simply submit the estimated kWh increase (as per expected mileage calculations) that the EV will add.

PEPCO Incentives for Electric Vehicle Owners in Maryland and DC

PEPCO has an Electric Vehicle (EV) Program for residential customers in Maryland. It is open to all qualified residents throughout the state. You can participate in the program if your electric vehicle is registered in Maryland.

This program was created to encourage off-peak vehicle charging. The benefits include lower off-peak electric rates for charging during the 16 hours of off-peak hours available Monday through Friday and all day Saturday and Sunday. This policy lightens the load and strain on the electric grid which improves the reliability for everyone. It also encourage the shift to clean energy which will reduce car emissions. And if you choose to charge your car with solar panels, you will achieve an even greater impact.

Another way you can make a difference is by shifting your energy usage to night time. Run your big appliances at night. Wash and dry your clothes at night. Run your dishwasher at night. Again, this will lower the burden on our power plants and it will also lower your electric bill too.

In DC, PEPCO is proposing special incentives to owner’s of electric vehicles. The program will offer lower electric rates to owners of EVs that charge their cars during off-peak hours. Some customers will also qualify for discounts on Level 2 smart charging stations that includes 100% of the cost of installation. For commercial property owners, PEPCO will install charging stations at a discount and they will also install them for free. PEPCO is also planning to install 20 fast charging stations along the main roads and in each Ward and in each quadrant of the city. Finally, PEPCO will be creating a $1,000,000 fund that is designed to provide grants for people and organizations with ideas that can help encourage a greater shift towards electric cars.

Let’s also help PEPCO increase electrification by considering a shift towards renewable sources from solar panels. Please contact us via this website or call us at (410) 923-6090. We have hundreds of installations throughout the Baltimore/Washington/Annapolis area. We look forward to helping you too.

Incentives for Electric and Hybrid Cars in DC

Washington DC’s government is encouraging the ownership of electric and hybrid cars with incentives that will save you time and money. For one, if you own an electric vehicle, you are exempt from emissions testing. If your car emits nothing, there is nothing to test. You simply need to register it with the DMV in DC. And if your car is a hybrid that is both electric and gas powered, you only need to pass a smog test. For questions about this, you can call the DC Department of Motor Vehicles at (202) 737-4404.

Fuel Efficient Cars get Reduced Registration Fees

You can also qualify for a discount on the first-time vehicle registration for a qualifying electric, hybrid or clean fuel vehicle. Their rules state that your car must get at least 40 miles per gallon in city driving. Check www.fueleconomy.gov to see how your car rates. You also must be the original owner of the car. If your car is used, you are eligible for the excise tax exemption. This exemption is the tax you pay upon purchase of a vehicle. So, the exemption can be a nice savings for you.

You might also qualify for federal tax credits. Eligible cars include electric, hybrid, plug-in hybrids, diesels and alternative fuel vehicles. Ask your accountant about how this might benefit you. And another benefit is that your insurance company might offer a discount. If they don’t, you might want to call around to find a carrier that does. These savings can really add up.

And finally, if your business has a fleet of 10 or more clean fuel automobiles, you can qualify for an exemption to the HOV lane. Again, call the DC DMV at (202) 737-4404 to find out about this benefit. Going electric and fuel efficient will put you in the fast lane in so many ways.

And, of course, we are always available to help you power your electric car with solar panels at your home, in your community or at your business. Please contact us if you have questions about generating most, or all, of your energy from solar.

Solar in Critical Areas – Maryland, Virginia and Delaware

Solar Panels, Solar Energy, Solar in Critical Areas AnnapolisWhat is the Critical Area?

The Critical Area includes all land within 1,000 feet of Maryland’s tidal waters and tidal wetlands. Along our precious shoreline of the Chesapeake Bay and its tributaries, we have had many homeowners looking to take advantage of enhancing their waterfront landscape with solar panels.

Aside from the clear economic advantages, we are in solar for all the right reasons; to protect the environment, preserve our natural resources, and to leave the world a better place. With that said, installing solar in the critical areas encourages us to comply with two important regulations that ensure shoreline preservation.

Lot Coverage

In the critical area, you are allotted a certain amount of lot coverage depending on the size of your lot. Our first step in the process is to prepare a “Lot Coverage Calculation” worksheet that indicates how much lot coverage you have available and ensures that there is legally enough space to account for the square footage of your new solar panels.

Buffer Management Plan

Though lot coverage is not impacted by solar installations outside of the critical area, the total area of additional lot coverage leads us to our next calculation. The Buffer Management Plan requires that every square foot of additional lot coverage is mitigated by planting either grasses, shrubs, or trees within 100 feet of the shoreline. The goal for this mitigation is to slow down the erosion of the shoreline, and we are big supporters of this mission. There is some flexibility with the types of flora that can be planted in this area, so we consult the homeowner in selecting preferred plants for their new shoreline oasis.

Though this process involves a few more steps in terms of permits, we have become subject matter experts thanks to our waterfront solar supporters in Kent County, Queen Anne’s County, Talbot County, Dorchester County and Anne Arundel County. Every county has a slightly different twist on their permitting requirements, and this helps local companies like SES thrive.
