Why do solar panels need cooling?

One problem in using photovoltaic panels to extract energy from sunlight is the effect of temperature. As the solar panel heats up, the efficiency of converting light to electrical power decreases, reaching an efficiency between 14% and 17% . For this reason, several cooling techniques have been implemented, named active and passive methods.

Do solar panels cool a house?
