Clean Technology

Maryland Solar CompanyMany people have a tendency to think of solar energy as a source of power. But, ultimately, the sun beaming down on the earth is more than that. It is also a heat generator, too. In other words, the sun’s rays are not only convertible to electricity, but also as a resource for inexpensive residential and commercial heating.

Solar thermal technology is this heat resource. It can be tailored to the individual homeowner’s needs by installing a solar thermal device that will collect the sun’s energy to heat your water, pool, and home. Certain systems negate the need for solar-driven electricity in the residence, and provide direct cooling and heating through a series of mirrors, sensors and controllers.

This is an important economical consideration for individuals and organizations of all sizes. Data reveals that as much as 75% of energy consumption in the home is the result of either heating water or space, or cooling space. This translates to nearly three hundred billion dollars in energy consumption annually in the United States alone.

Let’s focus on how this impacts you and your personal finances. Have you looked at your own heating and cooling costs and wondered how you might lower these expenses permanently? There are several suggestions that could make a lasting difference in your energy bills. For example, solar electric power panels are grid-like systems that continue to develop in sophistication while decreasing in size and cost.

Moreover, the installation and utilization of solar powered energy can lessen an individual’s impact on global warming by decreasing the size of the carbon footprint of single residences. Some experts hypothesize the use of a solar water heating system could reduce CO2 emissions by as much as 30%.

Now, that’s clean technology. The experts at Solar Energy Services have been a part of the clean energy movement for decades. We have developed our aptitude from years of training, and hands-on experience. Our expertise extends to both residential and commercial needs, and includes everything from the installation of solar panels, to solar-powered heating for homes, pools and businesses.

Isn’t it time you joined to solar-power movement?

Be Solar Savvy

Maryland Solar Company,Solar servicesThe most abundant source of raw energy is neither coal nor gas. It is not wood, wind, or even water. Look up and you will see a power generator without an equal – the sun! Scientists expect the sun to burn out in approximately 5 billion years. That means it should be able to generate kilowatts for homes, schools, and businesses over the next few decades at least!

Solar energy has developed into a variety of applications across the residential and commercial spectrum. Today, it is used to heat water for homes and pools through the solar thermal process. As well, solar power is collected in photovoltaic devices that then directly generate electricity using sunlight and semi-conductors.

Under the circumstances, it seems odd that mankind has not attempted to harness this limitless wellspring of electricity. Perhaps that is because collecting and converting the sun’s rays to usable current has been an intellectual challenge in the past. However, in recent decades, science and technology have collaborated to create a foundation whereby it can truly be possible for solar energy to become the single largest conductivity system on the planet.

Imagine never having to dip into our nonrenewable resources again. Imagine clean energy that leaves no waste byproduct. Imagine a form of power that does not decimate the earth, and does not make vast areas uninhabitable due to the disregard for the environment that often accompanies the collection of power resources such as gas and coal.

Solar Energy Services is here to make this possibility a reality. Our company has been serving the Washington D. C. and Maryland area for the past thirty-five years meeting our residential and business customers’ needs. Our solar design laboratory and separate headquarter offices are both located in Maryland. We are proud to be a vital member of the communities in which we are located. It is our mission to employ those who live in our area.

A Primer on Solar Power

Residential Solar Panels, Solar ServiceDid you know that attempts to harness the sun’s power through the development of solar cells dates back to the late 1800’s? I am sure that this, and other information, may be new to our readers. This article will provide you with some basic facts about solar power and solar energy. That way, you can join the conversation, and the renewable energy movement!

The first successful solar cell was developed in the early 1950s. It was made of silicon, and able to power small electronic devices. This was hailed as the beginning of a new era of energy resources, even then being acknowledged as having the potential to offer a limitless supply of electricity.

The first true application of solar cells could be found in the space program at NASA and in Russia. They were the only ones who could afford this technology in the 1960s.

The cost of solar cells continued to decline incrementally, but not so significantly that solar was a common source of energy through the 1970s. But, as the 1980s dawned, and ever since, solar power has insinuated itself into all aspects of life, commercially and residentially.

The first solar panels for buildings were developed in the early 1970s. In truth, this initial foray into the potential for large scale residential solar power was actually a solar array built into a rooftop. Panel development followed, as the cost and manufacturing efficiency increased.

President Jimmy Carter had solar panels placed on the roof of the White House in 1979. Everyone was getting into the act!

Welcome to 2018. Today it is common to find solar-powered cars, solar-powered telecommunications, and even solar-powered aircraft. One car company, renowned for their progressiveness, has incorporated solar panels into the roofs of their vehicles!

But, there’s more! Technology continues to expand the horizons of solar energy, making it affordable and applicable in new ways and new places. For example, it is possible that eventually solar panels on rooftops will be replaced with solar shingles!

Or, consider this, a solar fabric is being finalized that can be attached to houses as a cooling device!

We here at Solar Energy Services are excited about the future applications of this renewable source of energy for personal and commercial uses. You can count on us to utilize our superior knowledge and expertise to your advantage. We look forward to serving you!

PACE Solar Financing in Maryland and Washington DC

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.

DC Property Owners: Big Hot Water load = Big Solar Incentives

Commercial Solar Service, Annapolis MD

A growing number of building owners, developers and condo associations in the District of Columbia have come to realize that their building happens to be located in the most solar-friendly city in the USA .  Solar contractors, investors and financing vehicles are falling over each other to get solar panels on District roofs and start generating  the lucrative solar renewable energy credits (SRECs).   Whether via Direct Purchase, or $0 solar leases – SRECs are undoubtedly the reason for the solar season in DC (more to follow on those below).

However, before you sign on the dotted line and fill your roof with a 25-year solar PV (electric) system, as offered by 9 out of 10 solar professionals, make sure that you’re not losing the opportunity to vastly increase your return on investment with a Solar Thermal System.

Solar Water Heating Feasibility

The pre-qualification for a Solar Thermal System involves three questions:

  1. Does your building have a substantial, daily (365 day) hot water need? (i.e. apartment building/condos, restaurant, laundry, brewery, health center)
  2. Does your building have a centralized water heating system (as opposed to individual units throughout the building)?
  3. Can the building accommodate additional storage tanks?

If you answered YES to these three questions you really (really) should first consider a Solar Water Heating system either before – or at a minimum – in tandem with, a solar PV system.  (Shopper Beware – unless your solar contact has experience with solar thermal – which many do not – you’re going to have to be prepared to shop further).

What is Solar Water Heating (or Solar Thermal)?

Other than using the sun for energy generation, Solar Water Heating Systems operate entirely differently from their electron-shaking PV counterparts.  These time-tested, technologically mature systems are mechanical in nature and relatively simple.

Moreover, a solar thermal panel is 60 – 70% efficient; whereas a solar PV (electric) panel is typically 17 – 24% efficient.  Therefore, solar thermal panels generate substantially more energy per square foot than PV panels,  monetizing many more SRECs.

Solar Service , Home Solar Panels, Solar Renewable Energy

 

Let’s Review SRECs…

SRECs (Solar Renewable Energy Credits) – along with the 30% Federal Tax Credit and 100% Year 1 depreciation– are what drive the tremendous economic benefits of solar in Washington DC; one of several jurisdictions that have enacted a Renewable Portfolio Standard requiring that a specific percentage of electricity consumed 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 competitive energy suppliers 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 DC does not have the real estate to install large solar farms which can rapidly oversupply a market and drive down SREC prices.

How much are SRECs Worth?

Washington DC SRECs are currently trading at $395/SREC.  To provide a frame of reference, a 6000 sq ft rooftop in Washington DC outfitted with a 75kW solar PV (electric) system could generate around 90 SRECs/year (over $35,000/year).   Depending on variables such as system size, corporate tax rate and and project site attributes, this SREC income – combined with a 30% Federal Tax Credit and 100% Year 1 depreciation, typically result in IRR’s between 30% – 60% and a Simple payback of 3 – 5 years.    Assuming solar thermal is applicable, this same roof outfitted with a Solar Thermal System could fit a kWh equivalent of a 150kW+ system, generating 180 SRECs/year – and see an IRR of 50 – 80%, with a simple payback in the 1 – 2 year range.

Solar Service ,Home Solar Panels, Residential Solar PanelsMaintenance

Although Solar PV (electric) clients often opt for an O & M (operations and maintenance) contract through their solar installer, Solar PV Systems  have relatively minor maintenance needs; usually an annual inspection along with ongoing monitoring.    Solar thermal (water heating) requires a little more maintenance including a 3 – 5 yearly service which, at a minimum, includes a replacement of the propylene glycol/energy transfer fluid that can degrade with time.  Nonetheless, the impact of service costs on the overall IRR is relatively small and easily absorbed by the increased SREC income.

Press Release: Solar at the Chesapeake Bay Foundation

Press Statement
6-15-15

Solar Service, Home Solar Panels, Chesapeake MDCBF Merrill Center to Install 106 kW Solar System

(ANNAPOLIS, MD) The Chesapeake Bay Foundation (CBF) and Solar Energy Services, Inc. (SES) announced an agreement today for SES to design and build a 106 kW, grid-tied solar photovoltaic system at the Philip Merrill Environmental Center, CBF’s headquarters.

The Merrill Center rooftop solar system will include more than 370 solar panels from US manufacturer SolarWorld, as well as inverter systems from Solar Edge. The panels will be installed primarily on the available roof tops, but the design also calls for some unique solar shade structures to provide additional benefits to the facility and its occupants.

SES president Rick Peters shared that SES is pleased to participate in this marquee project. “I know personally that CBF has led the way on sustainable initiatives in our region for a very long time. It is an honor to be selected to construct this project, which will help advance CBF’s message and their environmental stewardship.”

The solar system is projected to produce more than 133 MWh of electricity annually, enough to power more than 10 average Maryland homes. This will significantly offset the facility’s consumption of traditional electricity.

“While we have had solar panels at the Merrill Center in the past, we are adding this new capacity because it is now more affordable as well as more efficient,” said CBF Vice President Mary Tod Winchester. “The new array will generate enough electricity to provide one third of the power for heating, cooling, and other needs of the more than 100 staff who work here. As a non-profit, we will not benefit from the many tax incentives available, but we encourage other individuals and businesses to closely examine the costs and benefits of adding solar generation.”

The project is expected to be completed before the end of this summer.

Solar Energy Trends

Some Positive Trends:

  • Solar Leasing on the Rise – increasing accessibility
  • System prices continue to drop
  • Maryland meeting its solar energy goals
  • Maryland Solar Industry exceeding 2200 jobs

Eastern Shore MD,Residential Solar PanelsThe Challenges:

Industry consolidation can be disruptive

Residential solar leasing is fast outpacing cash sales in many of the more developed states, like Maryland. It’s what many Americans want so it will continue to drive the market. It seems to work for more of America.   After all, we do like instant gratification and if I can save $10/month immediately, and feel good about it, where do I sign? While SES typically strongly advocates for cash sales to our customers who are able, no one can argue the enormous impact and value that the various residential financing vehicles have delivered. Getting solar access to the mainstream will be the most critical piece to advancing the development of distributed solar. It really has been transformational so far.

There’s other good news. System Pricing, though leveling off somewhat, has dropped dramatically in the past 5 years. While incentives decline as planned, the industry continues to drive down installation costs to maintain the impressive paybacks and internal rates of return.

Beneficiaries of solar price reductions include states like Maryland, who had the foresight to seed this industry over the last 6 years. Government and industry partnership in Maryland has built an economic environment that supports solar development and as a result, it is sustaining 2200 jobs while Maryland continues to meet its solar RPS goals. That’s right, our industry delivers over 2200 paychecks in Maryland. In fact, there is now a solar thermal equipment manufacturer in Baltimore. Much to be pleased about.

There’s also a darker side. Bankruptcies and consolidation of solar companies have carried the headlines quite a bit in the last year especially. While a natural part of the tech/business evolution cycle, consolidation and shake out are always disruptive, not only to industry members, but also to consumers of these solar energy products and services. As a result, all of the solar “investors” are asking lots more good questions – particularly about the longevity of the manufacturer and the installer. Popular questions, particularly in the solar PV panel world, are “Who will be here to support my warranty?” and “What is the design track record of these systems?”

The beneficiaries of these trends will be those with a proven commitment to the industry either through time or capital. It’s that commitment that gives customers confidence of future support if and when it is needed. Whether it’s an installer with 35 years experience or a manufacturer like SunPower that has 25 years in business, longevity is a key indicator of future availability to support the install base.

Supercharge your Solar Water Heater

Solar Thermal not Solar PV: When talking about solar and space heating, it’s worth mentioning that the panels used for this type of solar application are not the same panels that power a house, a light, or any other electrically powered appliance. In fact, the only similarity between a PV (photovoltaic/electric) solar panel and a Thermal Solar Panel is that they both absorb solar energy. However, how each panels processes and distributes that energy is entirely different.

Enlarged Domestic Hot Water System: In order to make a solar space heating system cost-effective, most space heating systems are designed to include the home’s domestic hot water supply – thereby offsetting the gas/oil/electric bill and returning the solar system’s investment. Therefore, any space heating system is basically an enlarged solar water heating system. These systems that combine solar water heating and space heating are often referred to as combisystems. This combination is achieved with a solar storage tank that comes equipped with two separate heat exchangers; one for the domestic hot water loop and one for the space heating loop. The cooler water returning from the heating system passes through the upper heat exchanger on it’s way back to the boiler where it does one of two things: It picks up some heat that was generated by the solar system or, if the tank is cooler than the returning water, acts as a buffer tank allowing the boiler to have fewer on / off cycles thereby making it more efficient.

Space Heating Infrastructure: Radiant floor heating systems are highly compatible with solar thermal energy. This is mainly because these systems are designed to operate at low temperatures and thus the solar system can contribute energy more of the time. Hot water baseboards, radiators and other hydronic heaters can also benefit, especially if an outdoor reset control is installed. The outdoor reset control adjusts the boiler’s target temperature according to the outdoor temperature.
Forced air systems can also be modified to accommodate solar by placing a fan coil inside the existing duct work. A controller senses when the fan needs to be activated and, again, a conventional back up system kicks on as needed.

Heat Dissipation in the Summer: Of course here in Maryland/Washington DC,  in our Mid-Atlantic climate, solar energy for space heating is being summoned at a time of year when insolation (sunshine) levels are much lower than the rest of the year. Therefore more solar panels are required to meet the quota. A family of four would realistically need two, 4′ x 8′ flat plate collectors for their home’s hot water supply. Depending on the required space heating square footage, this collector size may be increased anywhere between 30 – 100%. To avoid overheating in the summertime when space heating is no longer required, there needs to be a mechanism to dispose of the excess heat. This can usually be achieved with anti-stagnation functions on the controller or by installing a heat dissipater on the roof. An ideal situation is to redirect this excess heat to a pool or hot tub, thereby creating a year round triple-application system that provides the largest return on investment.
