An off-grid solar system is a solar panel system that has no connection to the utility grid at all. To keep a house running off-grid, you need solar panels, a significant amount of battery storage, and usually another backup power source, like a gas-powered generator. Grid-tied systems generally provide the best return on investment because of their low upfront cost and simple system design.

A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. The cost of producing photovoltaic cells has dropped because of in production and technological advances in manufacturing. When there is more local generation than consumption, electricity is exported to the grid.
