“Solar photovoltaic systems” refers to a wide variety of solar electricity systems. Solar photovoltaic systems use solar panels made of silicon to convert sunlight into electricity.

Solar photovoltaics are used in a number of ways, primarily to power homes that are inter-tied or interconnected with the grid.

Grid interconnection

In a grid-interconnected solar power system, your photovoltaic panel or array of panels is added onto a regular source of electricity (provided by your utility company). The use of solar energy can reduce your reliance on other forms of energy to any degree you choose, depending on how big a system you purchase. Learn more about grid inter-tied solar.

Some homes and businesses require a guaranteed source of power – and this can be provided by a grid-interconnected system with a battery backup.

Solar Photovoltaics are also used:

  • To independently power homes and other buildings
  • In portable photovoltaic systems
  • In small remote solar systems that power electric fences and traffic signs.
  • In solar powered products – everything from calculators to clothing

Grid Independent

With enough panels and a high enough rate of sunlight, a large solar photovoltaic system will be able to power a home. You can learn more about off grid solar.
