Solar Battery DC systems consist of the solar panel, mounting system, battery bank, charge controller and connection to the electronic device. The charge controller prevents the PV units from overcharging the battery. These systems store the sun's energy even on cloudy days or at night and also have a remote capability. Businesses use them to light their signs, water features that use high efficiency pumps that they made especially for these systems.
One of the disadvantages is they produce DC direct current while many appliances require AC alternating current. Depending on how much storage you need, the cost can increase with the amount of batteries needed, and the batteries require regular maintenance.
