Types of PV Systems

PV systems come in several flavours:

• Grid Inter tied systems integrate solar electricity using the grid as a secondary power source.
  
  
• Grid Inter tied with battery backup Add a battery to the system to collect excess solar energy for use when light is low. Also tied to the grid as a secondary power source.
  
  

• Off Grid Photovoltaic Systems are not tied to the grid as a secondary power source.
