Power Efficiency Guide Review
There are two types of roof penal systems. the off grid Power Efficiency Guide Review solar power system and the grid-tied solar power system. The off-grid power system, as the name indicates has nothing to do with the local grid and is your personal system that supplies power for your personal use and benefits. Usually, it is more useful for remote areas that are not connected to the main power grid. The power so generated is used for lighting and other applications.
On the other hand, the grid-tied solar power system remains connected to the local power grid. As a consequence, the surplus power that is not consumed by the producer or the owner of the solar system is fed back to the local grid system and gets distributed to other consumers, meaning that power produced but not utilized by you is not wasted or stored but is used by somebody else.
But, the others don't get that power for free. It's your choice if you like to give excess of power available with you to the local grid, which in turn pays you for your contribution. Now, that's a great benefit of having your own solar power system at your rooftop. No doubt, installation of system at your rooftop is expensive but if you decide to sell the excess of power, you have that opportunity of recovering your expenses while conserving energy at the sake tine.
Surely, you have seen solar panels, if not used them. Primarily these panels comprise of solar cells arranged and connected in a definite manner to collect maximum sunlight, which is transformed, to electric power. The panels employed for producing power give an output of approximately 2 amps at 2 volts. As it is the quality of solar cells and other materials used that determines the life of these panels, it makes better sense to make your calculations on the basis of watts versus dollars rather than the surface area of the panels.
