How does on-grid solar power system work?
The arrangement of solar modules or on-grid solar power plant works in such a way to absorb the sunlight and convert it into electricity. The electricity generated here in the solar on-grid power system is Direct Current (DC). And the solar inverter then converts the DC to Alternating Current (AC), thus making it power the electrical items.
This electricity with the use of net meter is then routed to the grid and supplied for day to day use. The net meter is a device that records the energy supplied to the grid and the energy consumed. At the end of each month, the outstanding is recorded and provided to the consumer with a bill.
It is recommended to use the on-grid solar power system if you want to reduce your electricity bill and having a reliable grid where power cut happens in the day time and less than 2 hours.
The solar power system is a complete setup ideal for home and commercial places, which helps in producing electricity by utilizing solar energy (sunlight). A solar power system is made up of solar panel (which absorbs sunlight), inverter (which converts DC electricity into AC), mounting structure (which holds the panels in place), batteries (helps to store the extra power generated), grid box and balance of systems (wires, nuts).
In other words, a solar power system is composed of numerous photovoltaic (PV) panels, inverter (a Dc to AC power converter), and a rack system that holds the PV panels in place (solar PV panels on the roofs of homes and businesses generate clean electricity by converting the energy in sunlight). Solar power system comes in 1 kW, 3kW, 5kW, 10kW, and several other capacities. It is a good choice for those who want to reduce their electric bills and their carbon footprint.
