Monocrystalline silicon solar panel

On-Grid: On-grid means your solar system is tied to your local utility's GRID. This is what most residential homes will use because you are covered if your solar system under or over-produces in regard to your varying energy needs. All this means for you is that your utility system acts as your battery space. Off-Grid: An off-grid solar system is a solar panel system that generates electricity, stores that power in solar batteries, and runs independently from the power grid. These systems encourage off-the-grid living, a lifestyle centered around energy independence and self-sustainability.
