Engineers working for them first calculate the electricity demand of the system and then size the solar hydro or wind system that has the capability of generating desired output. The size of the battery tank is another factor where special care is required and their engineers do it perfectly. The system they have in place is ridiculously cheap when compared to diesel generators. However, there are certain elements that need to be bought. It includes a prime mover in the form of wind turbines, Solar PV or even generators and electrical storage facilities. Here one can expect Inherent Off Grid to supply quality items for such purposes.
