Why Solar
How Solar Works?
On Grid Solar System
On grid/ grid-connected photovoltaic power system is an electricity generating solar PV power system that is connected to the utility grid. A on grid system is consists of Solar PV Modules, one or several inverters, a power conditioning unit and grid connection equipment. They range from small residential and commercial rooftop systems to large utility-scale solar power stations.
Working Principle
Solar PV Modules convert energy from coming from sun into electric energy, Direct Current (DC), which is sent to inverter.
The inverter then converts DC it into Alternating Current (AC) because you can’t use DC directly – all your electronics need AC supply. The PV cells may make excessive DC but all that DC can’t be fed into your main supply as it may be too much to handle. Inverter regulates the voltage of DC that it gives to the main supply.
Inverter converts DC into usable AC and feeds to the main supply.
Now that it is in your main supply, you can power your electrical appliance and enjoy free, clean and green solar.
Net Metering
In areas where net-metering policy is in place, the energy generated by a grid connected solar plant is recorded by the bidirectional energy meter which is installed on site and on grid system feeding excess power that it makes back to the grid and your electricity meter going backward. The net import and export of electricity will be adjusted per billing cycle.
Off Grid Solar System
An off-grid system is not connected to the electricity grid and therefore requires battery storage. Off-grid system has enough power generation and battery storage to meet the home or larger site requirements even in the of winter when there is little sunlight. The off-grid systems are usually only found in areas which are far from any electricity grid.
Solar PV Modules mounted on roof or near ground mounted site, capture energy from the sun and convert this energy into DC electricity.
A Solar Inverter converts this DC electricity into AC electricity.
The main switchboard takes electricity from the solar inverter or battery inverter and sends it to power your home.
The battery inverter is two way and can take surplus electricity from the main switchboard and convert into DC electricity to be stored in batteries or demand is their convert stored DC electricity from the batteries into AC electricity to power your house.
