Solar Off grid solar system

An off grid solar system is also known as standalone Solar Power System; these systems are totally independent of any electric utility grid.

Mostly its usage is based on rural areas where grid electricity is not available or other reason would be the high price of electricity. In such areas, it is best to produce your own energy via installing a solar power system.

Off Grid Solar Power Systems are used to collect and store solar energy to be used by household appliances. These systems typically generate from 100 Watts (very small systems) to 5 kilowatts (larger systems, multi-family homes).

Off grid Solar System

Solar Power System is composed of solar panels array, controller and a DC deep well pumps. Our Off grid solar system can be used in many application fields:

Solar power systems, or in other words grid connected systems, are connected to utility grids to feed power back into the grid, it is to transfer the energy produced by the solar system into the grid station. The system comprises of solar photovoltaic panels which are connected to the grid by the help of inverter. A photovoltaic panel generates energy by its system, which can be used in supply of electrical use to your nearby areas or the energy produced can also be sent back into the grid when the system is producing more than the actual requirements.
