An off grid solar power system does not connect to a local utility. Representing the largest investment of any solar solution, an off-grid system is best-suited for places that have limited or no access to utility power and low daily electrical usage. In an off grid solar system, solar panels are connected to a charge controller that uses power produced by solar panels to charge a bank of batteries, electrically storing the solar power for later use. The stored power travels from your batteries through an inverter which converts the DC battery power to readily usable AC power.
Off-grid solar may be a practical option for those in remote locations, cabins, or vacation homes. While this alternative lacks the peace of mind provided by the local utility, it does maximize energy independence and provides the environmental benefits of harnessing solar energy.
