Do Solar Panels Use Heat Or Light Energy

A solar panel uses both light and heat energy from the sun.

Do solar panels use heat or light energy.

One type of power called solar thermal does use the sun s light to generate heat which can be used for things such as household hot water or to generate steam to drive turbines and generate electricity. The light from the sun heats up the panels which can be used for household hot water or to generate steam and electricity. They couldn t be more wrong. Many people think the most efficient place to generate power with photovoltaic pv solar panels is a scorching hot desert where the sun bakes everything.

These panels directly make use of light to produce electricity. The solar panels use photovoltaic effects from the harvested light energy of the sun and convert the light energy directly to electricity. Then the heat is used for the various tasks in the home such as boiling water or running generators for lighting homes. The second type of solar power is produced by photovoltaic solar panels.

Sure there s plenty of sunlight. The other type of solar power is generated by photovoltaic pv solar panels which use light to generate electricity directly. They couldn t be more wrong. But those panels involve complex integration with hot water systems to operate.

When you get an array of panels installed on your site you realize that they are absorbing both light and heat energy. Many people think the most efficient place to generate power with photovoltaic pv solar panels is a scorching hot desert where the sun bakes everything. Nowadays there are two different technologies which are being used for electricity production solar thermal and solar photovoltaic. Only a part of the visible spectrum gets converted to electricity through excitation of electrons from valence band to conduction band and out of the rest of electromagnetic spectrum a part of the light energy dissipates as heat depending on the materials used.

Some solar panels do use the sun s heat to generate electricity and these are known as thermal panels. Now many homeowners think that photovoltaic panels work in the scorching heat. However photovoltaic panels use only light for energy harvesting. But the most important part harvested by a standard solar panel is the light.
