Solar energy emerges when light energy from the sun strikes a silicon solar panel to produce an electrical current. The silicon in the solar panels can transform light energy into electricity because the movement of elec... More » Science Chemistry

According to the Solar Energy Industry Association, solar power can involve generating current directly from the action of ultraviolet radiation on treated silicon using the sun's heat to boil water and drive an electric... More » Science Environmental Science Sustainability

A solar car uses photovoltaic cells to transform energy from the sun to charge a battery or to power the vehicle directly. The land speed record for a solar car is 55.2 miles per hour, set on Jan. 7, 2011 by the Sunswift... More »

The energy that powers the sun comes from proton fusion deep within the star's core. The extreme temperature and pressure rips atoms apart, allowing freed protons to combine first into isotopes of hydrogen and then into ... More »

Solar roof shingles work in the same way as standard solar panels, using photovoltaic cells to collect energy from the sun and convert it to electricity. It is the same technology first used in space by human-made satell... More » Home & Garden Outdoor

Install a solar panel by checking local zoning regulations, determining the location in which it receives the most sun, bolting the support to the roof and installing the panel on the support. Contact an electrician abou... More » Home & Garden Home Maintenance Tools

In plant cells, chloroplasts perform photosynthesis, a process that converts light energy from the sun into chemical energy in the form of glucose. Plants can later use this stored chemical energy to carry out activities... More »
