4 FAQs about Solar panels generate electricity and store heat

How does solar power work?

Solar power works by converting energy from the sun into power. There are two forms of energy generated from the sun for our use – electricity and heat. Both are generated through the use of solar panels, which range in size from residential rooftops to 'solar farms' stretching over acres of rural land. Is solar power a clean energy source?

How do solar panels generate electricity?

This process is constant. Over 500 million tons of hydrogen atoms are converted into helium every second, resulting in photons that generate solar energy here on Earth. In a nutshell, solar panels generate electricity when photons (those particles of sunlight we discussed before) hit solar cells. The process is called the photovoltaic effect.

How does solar thermal energy work?

Despite the heat, there are more hours of solar radiation, with little cloud interference. While photovoltaic solar energy converts light into electricity, solar thermal energy actually uses the sun's heat as its main source.

Do solar panels produce more electricity if temperatures rise?

Since solar panels rely on the sun's energy, it's common to think that they will produce more electricity when temperatures rise. However, that's not the case. Photovoltaic solar systems convert direct sunlight into electricity. Therefore, these panels don't need heat; they need photons (light particles).
