Off-Grid Solar System

Off-grid solar systems are usually found in remote locations where it is difficult and/or expensive to connect to the power grid. Solar power is a very cost-effective solution in these situations.

Did you know that the use of off-grid solar goes as far back as 1947 when it was used to make up for the decrease in energy during World War II?

An off-grid system is made up of solar panels and battery banks. The batteries store the sun’s energy to be used at night or on cloudy days.

Off-grid solar systems differ from grid-tied systems in the sense that solar is the primary source of electricity to the structure. This requires some adjustment of when and how the pwoer is used in order to live within the design of the system.

For example, the battery banks can store enough electricity for a household for 1 to 3 days (or more, depending on the battery size). If there is a longer stretch of cloudy days and the sun energy is running low, a back-up generator would need to provide power. For these reasons, off-grid solar systems are seen as a primitive or “remote-only” alternative to more common solar setups.

Can you install an off-grid solar system in the city? Technically this is possible, but doing so would exclude you from most government incentives offered to homeowners who switch to solar. Some federal tax credit (30 percent) is available for off-grid systems, but there are no incentives from the utility company. So while you can be off grid, it usually doesn’t really make financial sense in an urban setting.
