What is Photovoltaic Technology?
Photovoltaic technology involves the conversion of sunlight into electrical energy using specialized materials called photovoltaic cells. These cells are made from semiconducting materials, such as silicon, which release electrons when exposed to sunlight. The electrons flow through a circuit, generating a direct current (DC) electrical power that can be converted to alternating current (AC) using an inverter, making it suitable for use in homes, businesses, and industries.
