Photovoltaics use solar panels quizlet.

Solar photovoltaic pv panels are undoubtedly what comes to peoples minds when they talk about solar energy. In the 1960s the space industry began to make the first serious use of the technology to provide power aboard spacecraft. Thanks in part to research funded by the energy department s sunshot initiative photovoltaic solar panels have gotten dramatically cheaper over the past decade. Electrons in these materials are freed by solar energy and can be induced to travel through an electrical circuit powering electrical devices or sending electricity to the grid.

A pv system that operates in parallel with the utility grid and provide supplemental power to the building or residence. Photovoltaic pv devices generate electricity directly from sunlight via an electronic process that occurs naturally in certain types of material called semiconductors.

In june 2014 germany reached a significant milestone and national record by satisfying more than 50 of its electricity demand with 23 1 gigawatts of solar power which was half of the entire world s production at the time. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. It was billed as a solar battery and was mostly just a curiosity as it was too expensive to gain widespread use. What are the 3 main factors that affect the technological design of solar panels.

Sunshot was created with the aim of making solar power cost competitive with fossil fuels by 2020 and it has made significant strides toward that goal by supporting the development of. However with solar energy systems. The first photovoltaic module was built by bell laboratories in 1954. Also known as a grid tied system.

Considering that in an hour the sun radiates solar energy enough to cover for human energy consumption for a year then going green with solar pv panels is perhaps in the right direction. Since they are tied to the utility they only operate when grid power is available. Energy is collected during sunny periods and stored for use at other times. Start studying photovoltaic systems.
