What Is Photovoltaic (PV) Energy?
What Is Photovoltaic Sunlight changed directly into electricity is known as photovoltaic (PV) energy. The DC (direct current) electricity created by PV panels is converted to AC (alternating current) – the same current used in your home and transmitted on the power grid – by an inverter installed with your PV system. This power is then fed directly into your home’s overall electricity supply by connecting to the main circuit breaker panel. This is “parallel generated electricity” that works in conjunction with the existing utility-grid supply (grid-tied). During times when the PV system is generating less than the building’s demand, the additional required power will be automatically drawn from the grid. As PV production increases, the electricity meter will slow down depending on how much solar power is being generated. When the solar PV system is producing more electricity than is being consumed, the excess will flow on to the grid, making the meter run backwards. This electricity wi
