How is solar power used for heating?

a.) special cells store energy from the sun for later use.

b.) the sun heats water stored within panels containing copper tubes, and then the water flows into a home.

c.) heat from the sun causes a turbine to spin.

d.) the sun warms the ground from which heat flows into a home.

A.) Special cells store energy from the sun for later use.

Explanation:

Solar cells are used to convert solar energy to electrical energy. These are special cells composed of semiconductor material, mostly silicon. It absorbs photons and generates free electrons. A photovoltaic system consists consists of number of solar cells and placed on rooftops. The stored energy is later used to run electrical appliances.

Thus, option A is correct.
