Solar energy is a renewable source of energy that is sustainable and totally inexhaustible, unlike fossil fuels which are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity. The solar electricity that is produced can supply your entire or partial energy consumption.
PV ON Grid systems generate energy from sunlight during the day. This energy goes into a grid connect inverter which converts the DC current into AC current, similar to that of the grid. If you need more electricity than your grid connected solar system produces, that power will simply come from the main distribution grid. On the other hand, if you produce more energy than what you use, then you will find a credit for the surplus on your electricity bill.
A standalone solar system means that there is no connection to the public grid. When you are “off grid” it means that you must create your own electricity to run your home. In this case, solar panels charge batteries which store energy. We often connect batteries to an inverter which supplies 240V AC power to run most appliances.
The solar modules generate DC electricity. The DC power goes through a Solar ON Grid Inverter. The On Grid Tied performs the conversion of the variable DC output into a clean sinusoidal AC power Inverter output connected at LV Panel.
The Solar power will be synchronized with grid supply and supplied as the primary source of energy. Solar Generation and Grid consumption both will be measured in smart meter.
Solar Modules generates DC electricity in day time. The Charge controller in PCU (Power Conditioning Unit) charge the battery and Inverter converts DC input to AC. These systems will have option of charging the battery with grid also during non-sunny days.
