Photovoltaics

Photovoltaic systems, commonly known as solar cells or solar panels, were originally developed for use in space. Photovoltaic systems still power nearly every satellite that circles the earth because they have no moving parts and thus operate reliably for long periods without maintenance.

Individual photovoltaic cells are electricity-producing devices made of semiconductor materials. They come in a wide range of sizes and provide energy for everything from small consumer items like calculators to more advanced systems that power schools, homes and even traffic lights.

Sustainability in action

Photovoltaic systems have very little impact on the environment, making them one of the cleanest renewable energy technologies available, and they can supply electricity on and off the grid. Photovoltaic systems can operate where electricity is most limited and most expensive, making it an important component of a sustainable-energy mix.

While photovoltaic systems cannot solve our energy problems alone, they can make an important contribution. And they are unique in that individuals can use them to produce some or all of their home’s electricity needs. Take the technology to your home, literally, by outfitting your roof with photovoltaic film to harness the sun’s rays and generate power for your home. Not only are there tax incentives you can take advantage of, but the installation will lower your monthly energy bill and reduce your carbon footprint.

There are many companies that provide photovoltaic installations to residences and offices. Check here for more information on adding photovoltaics to your roof.

ACCIONA's commitment

ACCIONA focuses on building utility-scale renewable energy solutions, like solar power plants. Our photovoltaic installations total over 115 MWp, the majority of which is contributed to energy coming from our “huertas solares” (solar gardens) in Spain and Portugal.

In 2008 in Moura, Portugal, ACCIONA completed the biggest photovoltaic facility in the world in terms of installed capacity (45.6 MW). It has a total of 2,520 solar trackers, with an investment of 260 millon euros, and provides electricity to 30,000 Portuguese homes.
