Photovoltaic And Thermal Solar Panels

Solar thermal and solar photovoltaic.

Photovoltaic and thermal solar panels.

A standard photovoltaic panel only generates 20 of electricity during operation. Photovoltaic thermal pv t hybrid solar systems offer increased electricity production by cooling the pv panel and using the removed thermal energy to heat water all in the same footprint as a standard pv system. Solar thermal is currently used more often on large scale applications where lots of hot water is needed like a laundromat or a college dorm. Solar thermal electric energy generation concentrates the light from the sun to create heat and that heat is used to run a heat engine which turns a generator to make electricity.

The california energy commission licenses solar thermal plants above 50 megawatts and promotes solar photovoltaic installation through the renewables portfolio standard with building efficiency standards and as a partner in the california solar initiative. The energy is suitable for use in industries commercial and residential sectors. As the name may suggest to you solar thermals technology is used to create heat for your home. The heat in turn drives a heat engine which turns a generator to make electrical energy.

Solar thermal uses the sun s energy to generate thermal energy which is used to heat water or other fluids. Photovoltaic pv systems generate electricity rather than heat. Photovoltaic it is important to understand that solar thermal technology is not the same as solar panel or photovoltaic technology. The remaining 80 is heat.

In addition to being wasted this heat is also detrimental to the solar panel s efficiency which drops when the panel rises in temperature. Sunlight is collected as it would be via regular solar panels before being transformed into heat for water or your home in general. Solar energy in california falls into two categories.
