OFF GRID OR standalone power systems are not connected to the power grid . The energy produced is stored in batteries. They are suitable for areas that face frequent power cuts as it lets you save extra solar energy in batteries for use during power cuts. These type of Solar Power Solutions are also suitable for homes or facilities that do not have access to grid. A battery bank is set up which stores excess energy and can be used later when required. Here cost saving is not an advantage in such system because batteries have regular maintenance and recurring costs.
