This system combines the grid connection with the energy storage capacity of your home – i.e. instead of sending the excess power back to the grid (as in On-grid systems), you can store the energy for use during power demand peaks or low production due to less or no sunlight. This system is highly sophisticated and gives it users reliable, cost effective and environment friendly electricity at all times. In the world today energy prices are going north and creating imbalances in the lives of the masses. The great part about solar power is that it gives you a number of choices and provides you with the edge in dealing with the energy and its cost problems.
