This Never – ending, Non-polluting renewable source of energy saves money on your electricity bills and acts as a hedge against rising electricity tariffs. It also acts as source of revenue generation through Net Metering Framework. Going solar has significant environmental impact. It is one of the most influential decisions a homeowner or Business owner can make who is concerned with the environment. Solar power contributes directly to tackle the problem of Global Warming and climatic changes as every solar system saves some amount of CO2 emission, which otherwise would have resulted from conventional resources.
Sunlight is made up of photons. Photons contain various amounts of energy, corresponding to the different wavelengths of the solar spectrum. So, when Photons strike a Solar PV Cell (a semiconductor), they get reflected or absorbed or pass through. The absorbed photon’s energy when knock an electron in an atom of PV cell it frees the electron from atom, thus generating a flow of electricity. This way Solar PV Module convert sun’s energy into direct current (DC). But As most homes and business run on alternating current, So, the DC current is then passed through an Inverter to convert it into usable AC current. At that point, you either use the electricity in your house or send it back to the electric grid.
A Solar PV system is made up of different components which include Solar PV modules which are commonly called Solar panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (AC) rather than direct current (DC) is required; wiring; and mounting hardware or a framework.
Solar rooftop solution is a type of solar power system in which solar panels are installed on the roof of any residential, Commercial, institutional and industrial buildings. This can be of two types (i) Solar Rooftop System with storage facility using battery, and (ii) Grid Connected Solar Rooftop System.
Yes you will receive your electricity bills unless you have a Grid-connected solar power system including battery storage to generate your own electricity. But surely you can dramatically reduce your utility bill by installing a solar power system that matches your energy requirement.
The size of solar system depends on several factors. The First and the most important one is how much electricity you use, what all appliances you will run on solar power and for what duration of time. Next comes the size of your roof which will determine the no. of panels you can install, and the last one is how much you are willing to invest.
Net metering is a billing mechanism which allows residential and commercial customers who generate their own electricity from solar power systems to feed electricity they do not use back into the utility grid and earn some revenue in return. Only the grid connected rooftop system can work on net metering basis. With net metering you only pay for the electricity that you use beyond what your solar panels can generate. Net metering policies differ from state to state.
If you have a Grid connected solar power system installed at your place then it will shut off in the event of a blackout or power outrage to prevent utility repairers from getting electrocuted from your panels sending power back to the grid. However you can use inverter paired with battery along with your solar panels to provide you power backup during a blackout.
The cost of your solar power system will vary greatly depending on the Wattage of appliances to be run on Solar, Monthly energy consumption from these appliances, Energy Backup required, Roof space available for plant setup.
The direction of solar panel installation varies from country to country. The solar panels should be installed facing south if you are located in Northern hemisphere and true north if you are in southern hemisphere. Our country India, lies in the southern hemisphere so when the sun travels from east to west its inclination is towards south, be it summer or winter. So, In India the panels should be installed facing south direction.
