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.

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.

Solar Systems with Integrated Electric Vehicle Chargers

[vc_row][vc_column][vc_column_text]

â€Ķ.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.

The Fairytale of the 25 year Solar Workmanship Warranty

[vc_row][vc_column][vc_column_text]

Commercial Solar Service,Solar ServiceIf you’re like most solar shoppers, you prefer two or three bids on a substantial home improvement project; enabling you to sanity-check pricing, design options and find the overall best contractor-fit.  Included in these proposal comparisons is the Warranty. Most solar systems come with 3 warranties:

  1. Solar module manufacturer’s warranty; usually 25 – 30 years,
  2. Inverter(s) manufacturer’s warranty; usually 10 – 25 years (inverters convert DC energy to home-accessible AC energy)
  3. Workmanship warranty – entirely separate from 1 & 2 above. This insures the design and installation, insofar as contractor/labor portion of your install is covered for a given period of time, as determined by the installation company.

Industry Standard

As the popularity of solar has increased – so has the number of competing contractors and their accompanying solar proposals. All of these proposals should include a workmanship warranty. What will differ is the duration of the workmanship warranty. The standard duration for a residential solar system was always 5 – 10 years until a couple of years ago when some contractors started offering an unprecedented 25-year workmanship warranty. This is a good thing, right? On paperâ€Ķsure.

Compete only to Beat

With over 35 years in the solar industry, it’s fair to say we’ve seen a lot of solar installers come and go; especially in the last five years. The go-ing usually brings with it a slew of phone calls to our service department as solar system owners panic about no longer having their contractor around to honor the workmanship warranty; particularly those looking to resolve existing issues. Ironically, these are sometimes homeowners that chose the contractor over us due to a workmanship warranty of shorter duration. We have stuck with the industry-standard of 10 years, whereas some other installers have increased to 25 years to match the manufacturer warranties.

So, the big question – and the reason for this current article is – Why? If some of our competitors are offering a 25-year warranty – why don’t we? Seems only natural, given the fact that we’ve been in business for longer than 99% of them – greatly increasing the probability that we’ll be around to honor an extended workmanship warranty.

The Big Answer (in two parts)

  1. We’re keeping it Real: Understandably, a 25-year workmanship warranty is attractive to a homeowner because – by design – it matches the 25-year solar panel warranty. This does not change the fact that a workmanship warranty exists entirely independent of the installed equipment warranty(s). A contractor’s history, fiscal health and future plans have little or nothing to do with the equipment warranties. Given this, we avoid inflating the language in our contracts to provide misleading comfort to a home or business owner, with the sole purpose of beating out the competition at contract-signing time.
  1. We’re still keeping it Real: Of all the orphaned solar projects we’ve come across – we cannot cite a single known instance where a homeowner has taken legal action over an abandoned workmanship warranty item; simply not worth the court fees or the hassle. Most exert their energy on finding a contractor who will fix the problem as soon as possible and get their solar system restored to full working condition. Hence, the true value of the workmanship warranty is contractor integrity and the likelihood of whether they both intend to and will remain in business to honor their contractual agreement. For most solar contractors, the standard ten-year commitment reflects a realistic forecast of longevity and commitment; avoiding the temptation to head off into fairytale land in order to beat-out the competition.

Diagnosing and Preventing Critter Damage to Solar Panel Arrays

[vc_row][vc_column][vc_column_text]

Solar Service ,Home Solar Panels It’s no secret that hundreds of thousands of homes have installed roof mounted solar panels, with that number increasing with each passing day. The upward trend brings increasing problems that arise when tech meets nature. In an acorn shell we’re talking critters who nest, feed, chew and live their critter lives in and around solar panel installations.

Which Critters?

Any animal that can fit under your array poses a risk to a solar installation. Pigeons and other birds looking for a warm/safe place to build nests may do so under a solar array. This doesn’t usually cause any malfunction to the system. However, water build-up and bird waste may cause minor roof damage and may be more of a nuisance than anything.

Squirrels, mice and rats, on the other hand, can wreak havoc on a solar system. These members of the rodent-family have teeth that require filing down throughout the course of their lifetime. The wires, plastic connectors and small parts that run underneath the panels can be excellent teeth-filing equipment. We have seen squirrels chew the outer plastic covering of wires, as well as penetrate junction boxes on the back of panels and chew into the solar panel interiors. This type of damage will cause panels and even whole systems to cease power production.

Solar Service, Home Solar Panels ,Washington DC SolarWho’s at Risk?

Any solar system can be susceptible to critter damage. However, those most at risk are usually systems that are in wooded areas; particularly where tree branches extend close to the rooftops, allowing easy access for squirrels to make the jump from branch to solar system array. Although many homes and businesses fit this description, it’s also worth mentioning that for every critter complaint we’ve had – there are 20 or 30 more systems that have had NO issues with critters. However, it’s also worth mentioning that most of our customers are no more than 10 years into a 25 – 40-year solar system lifespan. Time will tell what the probability of critter-damage risk over a system’s lifetime will end up being.

Detecting and Diagnosing the Damage

Most solar system owners first become aware of a problem when their solar system does not seem to be producing as well as it used to. For homeowners with online monitoring, they may see that a string of panels – or individual panels (in the case of those systems outfitted with a microinverters or optimizers) are no longer registering power output. Others may hear scampering around on their roofs and may notice their utility bills creeping up. That’s when they call our service department. Our technicians need to remove and inspect each panel, as well as their connecting cables, suspected of damage. In most cases, we can remediate the wire damage onsite without engaging the solar panel manufacturer for a replacement panel. Whether this takes removal of every solar panel, or just a few – depends on the extent of the damage or ability to detect the extent of the damage.

Home Solar Panels,Solar Service, InstallationInstalling Critter Guard

There are a variety of anti-small-animal solutions out there for solar systems designed to create a barrier around the perimeter of the solar system. We usually choose the one most compatible with your solar system; depending on the type of racking initially installed. Most critter guards are made of some type of strong steel-mesh screen and they do not require drilling into the roof.

One of our more popular systems, the aptly named “Critter Guard” employs clips that attach to the bottom flange of the module frame and have hooks to snap the screen into place. The clips are painted steel and can be snapped to the appropriate length to accommodate height variations so there are no small spaces that accommodate a small animal. The mesh screen is vinyl-coated steel, rigid enough to keep out even the most industrious squirrel.

Residential Solar Panels ,Solar ServiceCritter Guard is now a standard option that we offer to our customers and we strongly encourage it when the structure has trees that are encroaching on the rooftop. While the tree branches may not be close enough today to make contact with the roof, over time, if not maintained, they can grow out to become that ideal path to an appealing new nesting site.

What are the costs involved?

The costs are always less if you can prevent the problem in the first place. Adding Critter Guard at the time of installation typically costs from $500 – $2000 depending on the size of your system; but of course this cost is integral to the solar system so most tax advisors would agree that the 30% tax credit would apply.

The costs for any rodent damage remediation will depend on the extent of the damage. Critter damage is not related to defects in installation covered under our standard Workmanship Warranty; neither will most solar panel/inverter manufacturers consider this damage a Material defect. Our service department charges Hourly-Time + Materials. These costs may range anywhere from $500 to $4000 for a mid-sized solar system including all remediation and installation of Critter guard to prevent further damage. We recommend inquiring with your home’s insurance agent to see if the costs can be covered under your homeowner’s insurance policy.

Washington DC Solar Owners and Selling Solar RECs Upfront

[vc_row][vc_column][vc_column_text]

Solar Service ,Home Solar Panels

Before we dive into this conversation – let’s be clear that SRECs (Solar Renewable Energy Credits) can be the most confusing part of figuring out the economics of a solar project.  Let’s also be clear that – as with anything confusing, (as well as possibly boring) – the temptation is to remove the confusion as quickly as possible.   In the world of solar installation and selling SRECs this sometimes translates to simply selling up to 15yrs of SRECs all at once to a solar installation company, who then installs the system at a bargain price.  Buyer beware – the immediate gratification of selling all of your SRECs in one fell swoop could be misleading.   When it comes to How and When you get paid for your SRECs “â€Ķthe Sooner the Better”  may not be a sound financial strategy.

That saidâ€ĶLet’s talk Solar Renewable Energy Credits in Washington DC.

Both Maryland and Washington DC, along with eight other states have enacted the Renewable Portfolio Standards which specify that a certain amount of the renewable energy generated within that state must come from solar.   Whether residential, commercial, or institutional, each time a solar system generates 1 Megawatt hour of energy – the solar system owner generates 1 SREC.  This SREC is then sold via aggregators to an  SREC market where it is bought by Power Companies to allow them to meet their share of the compliance obligation, or else pay a legislated fine (Alternative Compliance Payment, or ACP) for every SREC they are short.  Washington DC currently generates the highest SREC values in the country largely due to the fact that the District does not have the real estate to install large solar farms which can oversupply the market and drive down SREC prices.

How Much is an SREC worth?

The value of an SREC in a particular market is dynamic due to two primary factors

  1. by design, SRECs values are intended  to decline over time.  The legislated ACP which serves as a ceiling to the SREC price is usually scheduled to decline in future years. Among other factors, increased installations should lead to decreased system costs and less need for SRECs to help finance a solar system.
  2. The other reason for variations is due to market mechanisms.  Brokers buy and sell SRECs in order to help make a market for them.  When the market is undersupplied, SRECs trade high, at a price close to the penalty (ACP).  This is good for those selling SRECs.  If the market is oversupplied (like Maryland is currently), then SREC prices in that market will decline well below the penalty – not so good for those selling SRECs. Varying SREC payment options are intended to allow system owners to buy down their SREC price risk. The difference between an Upfront Payment option and a Brokerage Payment option (market price) can be many thousands of dollars to a solar system owner.  In an undersupplied market like DC, where there is very little price risk for SRECs, that upfront payment option leaves a lot of money on the table.

How many SRECs will my system generate?

The number of SRECs any given system will generate depends upon the output of your system.  For example, an optimized (as in good and sunny) 5.0 kW system in Washington DC would generate close to 6.0 SRECs/year.

How and When would I receive my SREC income?

SRECs are most commonly sold through an SREC aggregator/broker such as Washington DC-based SolSystems.  However, SRECs here in the District are so valuable – as well as stable – that solar panel contractors are also offering to buy your SRECs and simply deduct the upfront payment off the cost of your solar installation.  So THIS is the heart of this article:  Solar owners have 3 choices for how to get paid for their SRECs:

  1. Upfront Payment (all SRECs are forfeited for a 5yr or 15yr period)
  2. 3yr, 7yr or 10yr Annuity Contract (SREC prices Locked-in for a specific term)
  3. Brokerage (Current market price less broker commission).

Sticking with the aforementioned 5kW system example, the following table illustrates projected SREC values for the system, using current SREC prices (November 2016) offered by a competitive SREC aggregator).

System Size = 5kW                            SREC per Year = 6

So, reviewing the column above, this Washington DC Homeowner with a 5.0kW system has these financial options to choose from:

$$$$$:  Brokerage = $32,101.85 over 25yr life of systems (as warrantied)

$$$:  *Annuity =  $18,690 guaranteed then sign-up for another annuity or go Brokerage

$:  Upfront = $8025.60  SRECs cannot be sold again until 2032.

*Annuity is also available in 3 or 5 yr increments, as well as the 10yr

The Brokerage price is exponentially higher than the other prices, does that mean there’s a lot of risk?

Some risk – yes, because you’re not locked-in to a static price.   But remember – historically DC SREC pricing has remained stable (the geography does not accommodate  huge solar farms that can flood the DC SREC market).  You can receive an email monthly that allows you to check on current pricing AND should the price start to decline – you can, at any point in time, switch to an Annuity.  .

If I choose the 10yr Annuity Option and lock-in my SREC pricing, what happens at the end of that time period?

You simply choose another payment option being offered at the time of contract experation.  Maybe you’ll opt for brokerage – or another annuity, up to you.  Same with the Upfront Payment, after 15 years.

How do I receive my SREC income?

Via check from the SREC aggregator which most pay quarterly (except with the Upfront Payment option which would be one-time).   This generally starts around two months after your system has been interconnected by your Utility and the SREC contract set-up.   We do advise that the contractual SREC relationship be kept between a professional broker/aggregator and the solar system owner.  Third parties, such as the solar panel installation company, may find themselves in a conflict of interest.

If the solar system installer is not buying my SRECs, who sets up the contract?

Most reputable solar panel installation companies will coordinate the initial set-up of your SREC contract with an SREC aggregator, as they have immediate access to the documents required for the initial set-up (Passed Building Permit, Interconnection Approval etc.).  Many installers have one or two aggregators they’re used to dealing with – or you may choose your own.

PACE Solar Financing in Maryland and Washington DC

[vc_row][vc_column][vc_column_text]

Typical Commercial Challenges

As veterans of the small commercial solar market in this region, we are very familiar with the challenges of financing solar energy systems to this group of property owners.  Small businesses want solar as much or more than any other market segment, but they are capital-constrained like no others so they need affordable financing.

Third party solar developers have been the answer for other markets.  They can easily finance large systems because the cost of assessing the applicant’s credit is well worth the return.  In the case of residential systems, they can use universal tools like credit scores to help manage their risk.  For the small commercial and non-profit market, there hasn’t been a super-attractive  way to finance solar, until now!

Commercial Solar Systems Now Recognized as Public Benefit

Washington DC and Maryland now have laws and programs in place for commercial (and nonprofit) property owners to utilize PACE.  Property Assessed Clean Energy (PACE) is a vehicle that is used to finance energy improvements for buildings.  It operates under the recognition that energy improvements are considered to be a public benefit.  As such, PACE uses the property tax as a vehicle to structure the financing payments – much like we would finance a sewer extension, but in this case specific to one property.

PACE is very appealing to property owners because they can add significant value to their building on a cash-flow-positive basis without personal guarantees or the application of additional debt to the balance sheet.  The financing payment must be less than the savings and it’s paid in the form of a special assessment on the property tax bill over the term of the financing arrangement (5-25 years at competitive rates).  Multiple energy improvements (i.e. lighting, solar, new roof) can be bundled into one financing package.

The best thing about this approach to financing solar is that the property owner will own the system, not a third party.  The property owner gets all of the benefits, including the energy savings, the substantial incentives, the marketing value, and the satisfaction.  All it costs them is the interest on the financing which pales in comparison to the savings.

More info is available on your webpage on our PACE webpage but you may just want to pick up the phone and call us to see if your property is eligible.

The Ballasted Solar Attachment: Maryland and DC Solar Panels

[vc_row][vc_column][vc_column_text]

Commercial Solar Energy, Residential Solar PanelsWays in which solar panel arrays can affix to a commercial building are as many and varied as the buildings they serve.  In this article, we’re focusing on one popular method of attachment – the Ballasted roof mounted system.

Many commercial solar prospects in and around the Maryland/Washington DC area have buildings with flat or low-sloped roofs.  These are generally defined as a roof with a 3:12 pitch or less.  For these applications, ballasted systems can offer a way of attaching solar arrays without any (or few) roof penetrations.   Many building-owners prefer this method of attachment as it negates the risk of leaking, particularly on flat roofs that may collect water.  With a ballasted system, the arrays are held down using the weight of the existing solar panel arrays, racking and – most importantly – concrete blocks.  These blocks are placed methodically throughout the system design to secure the arrays in place, resisting wind loads or other types of disturbance.

The addition of the ballast blocks to the solar system arrays adds additional weight to the roof.   As with any commercial solar project, this weight load is analyzed and approved by a licensed structural engineer as required by the permitting jurisdiction – with some differences in each locale.   Ballast racking manufacturers also specify the amount of blocks required throughout a design.  The number of blocks per panel typically varies throughout design due to array proximity to building edges, parapets, or other inconsistencies that can affect wind and snow loads.

Although ballasted systems have many advantages, as with any design, they have their disadvantages and are not compatible with every type of commercial building.   Let’s look at a generalized comparison scenario between a roof penetrated system and a Ballasted System:

Roof Penetrated System

Ballasted System

Labor Costs and Criteria HIGH:  Penetrations require flashing and sealing techniques – sometimes requiring coordination with a roofer. LOW.   Labor skills required for installation are fairly straight-forward and require no roofer coordination.
Panel Count INCREASED:  Systems attached to roof substructure require less roof space for mounting. DECREASED:  Ballast-blocks require roof space and can limit the available space for solar panels
Roof Loading DECREASED.  No concrete/ballast block INCREASED:  Ballast blocks add weight to the roof
Design Criteria FLEXIBLE:  Attached racking systems can usually negotiate hatches, HVAC equipment LESS FLEXIBLE:  Because of the increased space required per panel – designs may be more rigid.  However most ballast racking does have reasonable flexibility.
Roof Pitch 5 – 45 degrees Generally less than 10 degrees

 

Multi-roofed commercial applications may have a variety of racking types for both sloped and pitched roofs. There are other options for flat roofs also, including attached and hybrid solutions that use a combination of both penetrated and non-penetrated techniques.

Fannie-Mae Agrees: Solar is a MUST-DO for Homeowners

Fannie Mae Agrees:  Solar is a MUST-DO for homeowners

Solar Service, Home Solar PanelsJust last month, Mortgage Giant Fannie Mae announced their new mortgage option that allows solar energy projects to be rolled into the final mortgage amount.  Namely, the HomeStyle Energy Program is hot news for solar fans who use a Fannie Mae-approved lender for their mortgage; whether considering a first-time solar system purchase, or currently financing an existing solar system with an equity line of credit or unsecured loan.

Typical Solar Financing and Solar Energy

It’s no secret that solar energy system installations in Maryland and Washington DC have taken off like gangbusters.  In previous years, many Maryland homeowners were choosing to lease/rent solar panels in an effort to avoid upfront costs.  However, when compared with an outright solar purchase – a 20yr (or similar) solar lease proves to be quite expensive – as with most rental agreements.    Depending on whether the solar shopper lives in Washington DC or Maryland, the financial incentives (tax credits/SRECs) usually pay for between 40 – 80% of the system cost.  100% of this upfront solar cost needs to be sourced by the homeowner who usually use a financing vehicle such as an Equity Line of Credit or some sort of Unsecured Loan.

Fannie Mae’s Game-Changerâ€Ķ

As of June 2016, Fannie Mae borrowers have access to a new Energy Loan that allows them to simply add the cost of their solar system to their existing mortgage.  Here’s what makes this form of financing a game-changer:

  • Super-Low APR:  HomeStyle Energy can be used for new projects or to take higher-interest unsecured loans/lines of credit and refinance them or roll them into a potentially lower-cost mortgage.   In all likelihood this will result in unprecedented low financing costs for solar energy.
  • All Costs Covered:  Most financing vehicles have a non-negotiable cap on the loan amount, forcing some Homeowners to come up with a down payment.  With this program, lenders can finance up to 15% of the final property value.  For example, a typical single-family home located in Annapolis, MD may appraise for $350,000.  The available amount for the solar system on this Annapolis home would be $52,500.  In most cases, this amount would far exceed the amount of capital needed to complete the project, considering that most solar projects fall in the $24,000 – $34,000 range (before government incentives).
  • Peace of Mind:  The improvements also have to come with an energy report, whether a Home Energy Score Report or a Home Energy Rating Systems report, and must specify the monthly savings to the borrower.   Homeowners can rest assured that their mortgager fully supports the home improvement investment.

Does Every Home Qualify?

At this point in time, only Fannie-Mae  homebuyers or refinancers qualify.  The program does not extend to new construction or manufactured housing.  The following are eligible to apply:

  • New homebuyers
  • Existing mortgage holders looking to refinance their new solar system
  • Existing mortgage holders looking to refinance their existing financed solar system

All applicants have 180 days from close of mortgage note to complete the solar installation.  Bear in mind that refinancing homeowners may incur closing/additional fees in the transaction.

Contact your mortgage representative to see if the HomeEnergy Program is right for you.
