Located in Golden, Colorado, NREL is the United States primary laboratory for renewable energy and energy efficiency research and development. Currently NREL is funded through the Department of Energy and receives the majority of funding from the DOEs Office of Energy Efficiency and Renewable Energy (EERE).
NREL’s mission and strategy are focused on advancing the U.S. Department of Energy’s and our nation’s energy goals. The laboratory’s scientists and researchers support critical market objectives to accelerate research from scientific innovations, such as advancements to the photovoltaic cell solar panels, to market-viable alternative energy solutions.
Established in 1974, NREL began operating in 1977 as the Solar Energy Research Institute. NREL found early success under the Jimmy Carter Administration, receiving large amounts of funding, using the research to expand the populations knowledge concerning solar power. However, during the Ronald Reagan Administration, funding was cut by 90%. Since then funding has fluctuated.
In 1991, the name was changed to NREL and was designated a national laboratory of the Department of Energy. Currently, NREL is managed for the Department of Energy under the Alliance for Sustainable Energy, LLC.
NREL’s R&D areas of expertise are:
- Renewable electricity
- Renewable fuels
- Integrated energy system engineering and testing
- Strategic energy analysis

Born in Paris, Edmond Becquerel (1820-1891), a French physicist in 1839, is known for his studies in the solar spectrum, magnetism, electricity and optics. He is best known for his discovery and unraveling the key principle to solar energy cells, the photovoltaic effect. He received his doctorate from the University of Paris, and eventually took
a professorial position at the Agronomic Institute of Versailles. He was especially interested in phosphorescence and luminescence, chemical reactions caused by exposing certain substances to light. In the1840s he found that these reactions could produce an electric current in both liquids and metals. The connection between light energy and chemical energy was seized upon by many scientists in the following years, and research has led to the development of the photoelectric cell.
Photovoltaic effect
The photovoltaic effect is the basic physical process through which a photovoltaic cell converts sunlight into electricity. Sunlight is composed of photons which are packets of solar energy. These photons contain different amounts of energy that correspond to the different wavelengths of the solar spectrum. When photons strike a photovoltaic cell, they may be reflected or absorbed, or they may pass right through. The absorbed photons generate electricity.

Four Reasons Why Building Your Own Solar Panels Is a BAD Idea

If you Google solar panels, most of the top results are for websites selling DIY solar panel kits. The same search on YouTube is filled with videos on making your own solar panels.
While building and installing your own solar panels might seem like a good way to save some money, there are several reasons why doing it yourself is a bad—sometimes even dangerous—idea. Here are five reasons why you should work with a professional solar panel installer:
1) You will pay more for materials.
Professional solar panel installers are able to obtain a higher quality product at a lower price. The panels you get at Home Depot or other online retailers are, to say the least, a much lower quality. They are less efficient and will generate less electricity, meaning that you will have to install more panels to generate the same amount of energy, which will ultimately cost you more than a high-quality solar panel you get from a professional company.
2) Doing your own electrical can be dangerous.
This might seem obvious to some, but you’d be surprised how many people think that can do their own electrical work without having any formal training. Unless you are an electrician, installing your own electrical devices, much less a set of solar panels, can be incredibly dangerous. A professional installer will have both roofing and electrical experience, and will know how to safely install your solar panels.
3) Protecting your purchase through the warranty
Companies can be picky about their warranty. If you install your own solar panels, even the smallest mistake can void your warranty. Then you’re stuck with a system that might not be working right, has no warranty protection, and still cost you some money to install while not generating any income.
4) Paperwork, Paperwork, Paperwork
It’s great to use green solar technology and do your part to improve the environment and reduce our dependence on oil. But there’s also a financial benefit, with federal, state and local solar tax credits and grants, not to mention getting Solar Renewable Energy Credits (SRECs).
Obtaining those tax credits, grants and SRECs can be a bureaucratic nightmare. There are numerous forms to fill out, certifications to be obtained, and other hurdles that the homeowner might have to jump through. And if you make a mistake on any of your forms, you have to start all over from the beginning. Doing all this yourself can add months—sometimes years—to the time it takes for you to see a financial benefit of your solar panel system.
A professional solar installer can help you get every single cent you deserve from your solar panels, while installing a higher quality product safely.
We don’t like to brag too much (after all, this blog is about more than our company), but here at Solar Energy World, we take pride in helping our customers through every step of the solar installation process. From the first free solar analysis, through the installation and inspection, to the processing of paperwork, we provide customers with a seamless experience that makes switching to solar easier.
Far easier than doing it yourself.

In celebration of Earth Day’s 40th anniversary, we’ve list 40 interesting and alarming environmental facts. We’ve posted these facts every day for the past 40 days – thanks for listening and sharing with others!
- Approximately 20 million people across the United States celebrated the first Earth Day, on April 22, 1970. Today, more than 1 billion people around the world take part in the event.
- In 1995 over 200 of the world landfills were full.
- Each person throws away approximately 4 pounds of garbage per day.
- Approximately 5 million tons of oil produced in the world each year ends up in the ocean.
- The energy we save when we recycle one glass bottle is enough to light a traditional light bulb for four hours
- In, 1931, Albert Einstein, collected a Nobel Prize for is work in solar and photovoltaic experimentation.
- Every ton of paper that is recycled saves 17 trees, 2 barrels of oil, 4,100 kilowatts of energy, 3.2 cubic yards of landfill space and 60 pounds of air pollution.
- 14 billion pounds of trash is dumped into the ocean every year
- 84% of all household waste can be recycled

- Only 11% of the earth’s surface is used to grow food.
- If every newspaper was recycled, we could save about 250,000,000 trees each year. Unfortunately only 27% of all American newspapers are recycled.
- A highlight of the annual Earth Day ceremony at the United Nations is the ringing of the Peace Bell that was given to the UN by Japan. It is made from coins given by school children to further peace on our planet.
- By using renewable energy sources to provide your daily energy needs we can decease CO2 emissions with 20,000 pounds less of carbon dioxide each year, including 50 pounds of nitrogen oxide less, and 70 pounds of less sulfur dioxide omitted into our atmosphere.
- Americans throw away enough aluminum to rebuild our entire commercial fleet of airplanes every 3 months.
