SOLAR ROOFTOP
A rooftop solar plant refers to one where the solar panels are mounted on top of a residential or commercial building.When the sun shines onto a solar panel, the photovoltaics (PV) cells in the panel absorb the sunlight, helping in the creation of electric current. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories.
Rooftop Solar PV is an investment that saves electricity bills as well as the environment.
ADVANTAGES OF SOLAR ROOFTOP: · No additional space required for installation and require lesser space than ground mounted systems · Cost-saving as compared to electricity · Secure investment as it is immune to the varying electricity prices · Reliable source of energy for remote areas · Reduces carbon footprint as it helps cutting the emission of greenhouse gas · Low maintenance · Easy to calculate expenditure as it is a free source of energy
With the fluctuating prices of electricity, the calculation of expenditure for a certain period of time gets difficult. Whereas with Rooftop Solar the cost calculation of electricity generation for next decade can be done easily. Therefore, it is a secure investment. For ex: If an individual house consumes 360 units of electricity per month, then a 3 KW system would save approximately Rs. 33,000/- year ( Percentage of energy saved). UTILITY SOLAR POWER PLANT Solar Power Plant also known as the Photovoltaic (PV) Power Plant is a large-scale PV plant designed to produce bulk electrical power from solar radiation. It is the cleanest and most reliable form of renewable energy available that can be used in several forms to help in power supply for residential premises and business. Solar panels are composed of several individual solar cells which are themselves composed of layers of silicon, phosphorus (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the photons and in doing so initiate an electric current. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells which then pull these free electrons into a directional current. A Photovoltaic Power Plant is a carbon negative over its lifespan, as any energy produced over & above that to build the panel initially offsets the need for burning fossil fuels. Even though the sun doesn't always shine, any installation gives a reasonably predictable average reduction in carbon consumption.
