Interesting Facts about Solar Energy

Maryland Solar CompanySolar energy as a topic is quite interesting. What follows are some fun facts that should increase your knowledge on the subject.

  1. Solar energy comes directly from the natural energy that is generated by the sun.
  2. It takes the sun’s rays eight minutes to travel through space and reach the earth’s atmosphere.
  3. Solar cells are designed to capture solar radiation and change it into electricity. This electricity is used to power homes and businesses.
  4. Most solar panels face south in the United States. It is the optimal position for capturing solar radiation.
  5. Even when the sun is not shining you can still use solar energy to power homes and businesses. That’s because solar cells are able to store energy for later use.
  6. Solar power is simply the most eco-friendly, inexpensive and safest form of energy on the planet.
  7. Solar energy, in the form of solar panels, solar batteries and solar cells, can be used to run everything from central air conditioning to a houseful of electronics.
  8. According to one expert it is possible to power the entire earth with solar energy, making the planet reliant solely on renewable (and clean) energy. To do this, solar panels would have to be installed on a little less than 200,000 square miles of land. While this may sound like too big a challenge – consider the fact that there are 57 million square miles of land on the entire earth and it is apparent the project is quite doable, with room to spare.
  9. There are numerous health benefits that come with the utilization of solar energy. First and foremost, it does not have pollution as a byproduct. The only time there is any pollution generated is during the manufacturing of the solar panels themselves. This is important to note because the production and use of all other forms of energy cause pollution in several forms – either in emissions into the air, as runoff into our groundwater, and the desecration of natural, nonrenewable resources.
  10. While you can purchase the solar system outright, that is not the only option for accessing this energy resource. There are instances where it is possible to rent or otherwise finance a solar system.

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.

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.

Commercial Solar Water Heating: ANOTHER Renaissance?

Washington DC Solar ,Commercial Solar ServiceSolar water heating has quite a long history. In the United States alone, the industry has boomed and busted 3 times in the last 130 years – each time displaced by cheap energy. Many are surprised to know that the first US patent for a residential solar water heater was issued in 1891 to Clarence Kemp, a Baltimore inventor. That’s right, 1891.  In the 1920’s, 30% of the homes in Pasadena, CA had solar water heaters.  With the discovery of natural gas resources in the region, the industry evaporated almost overnight.  Solar thermal technology is mature and efficient; the problem lies with allowing our commitment to solar to dissolve in favor of decreasing natural gas prices.

In these previous industry “busts”, energy became cheap and we were lulled into a false expectation of stable prices. Each time, not long after the industry was dismantled, energy prices began to creep back up, making us long for that clean and cheap solar energy again. So today Solar Water Heating is on the rise again. Will it be different in the 21st century or are we doomed to repeat the same cycle? What was it that Winston Churchill said about failing to learn from history….?

The recent surge in US solar water heating deployments began in 2008. This resurgence, especially at the commercial scale, has helped to drive up adoption rates while scaling down installation costs. Several factors are converging in recent years to bring about this renaissance:

  • Engineers, architects, and contractors are becoming increasingly familiar with this mature technology – improving costs with increasing experience
  • Regional incentives are bolstering the existing federal incentives to reduce the capital investment.
  • The federal government has mandated that a minimum of 30% of water heating must come from solar for new construction or major renovations on federal buildings.
  • Project Developers like Skyline Innovations (http://www.nextility.com/) have introduced new business models to help deploy these systems for those without available capital.
  • Property owners increasingly want to have more control over their energy budget
  • Various societal pressures continue to reward solar adoption
  • An improving economy has allowed property owners finally to reinvest in their buildings

Remarkably, much of this has occurred despite a backdrop of rapidly falling natural gas prices (the primary heating fuel for commercial water heating), decreasing drastically from 2008 to 2012. However, in the last 18 months, natural gas prices are climbing again in a trend that is likely to continue: gas exportation; deployment of energy intensive manufacturing in the US; diversion of more natural gas to transportation (locomotives, trucks, fleet vehicles and eventually automobiles); conversion of more power plants and residential heating to natural gas.In light of these trends, property owners are rapidly moving forward to install solar water heating systems before the financial incentives expire. Business owners with substantial hot water loads in Washington DC and Maryland are able to achieve simple ROIs of 2-7 years. This approach requires them to take a slightly longer perspective, recognizing that they are buying 30+ years of energy up front for a fixed price (with generous subsidies). Whether financed independently or through the bank, building owners are able to lock in their energy prices and hedge the inevitable increase in fuel costs while leveraging all of the other benefits of renewable energy.

If you have any doubts about this trend, visit our commercial solar water heating page and take a look at the photos of just a subset of the projects we’ve been deploying in the region (https://solarsaves.net/commercial-solar-water-heating/).

Maryland Solar Water Heating Bill Moves Forward

The House of Delegates voted 132-5 Saturday, following the Senate’s unanimous 47-0 vote March 17.

The legislation would allow owners of solar water-heating systems to sell renewable energy credits. The credits are bought by utilities and power companies that need to meet government quotas of renewable energy generation; if they can’t generate enough green power on their own, they can buy credits from someone else who has.

The ability to generate credits via solar water heating makes those systems a more attractive investment and rewards the buyers for using less fossil fuel. That is expected to be a boon for the green power industry, seen as a growing source of new jobs.

Gov. Martin O’Malley pitched the legislation along with dozens of lawmakers as co-sponsors. House and Senate versions of the bill still must be passed by the opposite chamber, which is expected since the two bills are identical. O’Malley is then expected to sign off.
