Solar Electric Off-Grid Systems
Off-grid systems are traditionally used in remote places where the utility grid does not exist or would require exorbitant connection fees. Although this is where they are traditionally used they can work anywhere.
Since these home solar power systems operate with no connection to the grid, you don’t have any electricity bills to pay and you won’t experience any blackouts that occur on the utility-grid.
People choose this system type for several reasons such as the appeal of an independent lifestyle, the overall reliability off-grid systems provide, or the cost of bringing utility lines to such a remote location costs more than a home solar power system.
Living off-grid, however, doesn’t afford you the ease and comfort of on-grid living. Off-grid living often entails making adjustments to electricity usage habits to ensure living within the limitations of the system’s installed design specifications.
Don’t take this as having to sacrifice all the finer electrical luxuries of life but see it more as a move towards greater electric conscientiousness.
The main differences between grid-tied systems and off-grid systems is that you:
- Have a connection to the utility grid
- Need to have a battery bank to store electricity when the Sun is not shining
- Requires a back up generator for those times when you don’t have enough energy stored in your batteries to meet your energy needs
