What is Solar PV?
It is the change of light into electricity.
Solar Electricity is often called Solar Photovoltaic (PV).
Photo + Voltaic (Light + Electricity)
Solar PV Systems Explained!
A solar photovoltaic (PV) system uses solar PV modules to directly convert light to electricity. The modules generate DC electricity that is changed to AC electricity by an inverter. The inverter then sends the electricity into the building through the load center panel, powering any loads that may be on. There also two electrical meters, one is the Production Meter and the other is the Utility or Net-Meter. The Electrical Utilities track your solar production and electrical usage through both of these meters.
DC and AC Current
DC and AC are different forms of electrical current. Direct current (DC) electricity as a positive and negative output, just like a battery, or a solar module. Alternating current (AC) electricity has alternating outputs, and is just like a wall outlet, or the utility grid. In order to go between the two types of electricity we must use an Inverter (DC -> AC), or Converter (AC -> DC).
