STUDY TO ELECTRICITY GENERATION FOR A BUILDING FROM UNCONVENTIONAL ENERGY SOURCE.

Photovoltaic power systems convert sunlight directly into electricity. A residential PV power system enables a homeowner to generate some or all of their daily electrical energy demand on their own roof. The house remains connected to the electric utility at all times, so any power needed above what the solar system can produce is simply drawn from the utility. PV systems can also include battery backup or uninterruptible power supply (UPS) capability to operate selected circuits in the residence for hours or days during a utility outage. Sun is the largest source of power if we utilize it. From plants to animals, from human beings to domestic insects, from technology to science, nothing seems to maximize its existence without the availability of light.
