Solar On-Grid System: Connecting Your Home to the Sun's Energy
An on-grid solar system, also known as a grid-tied solar system, is connected to the power grid. The majority of Indian families with a dependable grid connection rely on on-grid solar systems to meet their energy demands. We at Sanelite Solar, specialise in the installation of on-grid rooftop solar systems for both independent households and housing associations.
The on-grid solar power plant for houses is a thoughtful combination of many components:
1. Solar panels
2. Solar inverter
3. Mounting structures
4. Bi-directional meter
5. Bi-directional meter
An on-grid solar power system is built for smaller purposes such as a single residence and has several capacities: 2 KW, 3 KW, 5 KW, 10 KW, and so on.
Remember, a solar system can have considerably higher capacity than 10 KW, however, the government only grants a subsidy on residential installations for solar systems up to 10 KW.
A standard Indian family with a monthly power expenditure ranging from 1500 to 3000 has a demand of just 2 to 3 kW.
The functioning of a residential on-grid solar system
An on-grid solar system generates energy using solar panels and then proceeds through many processes to keep your home powered up during the day and at night. Solar panels capture energy from the sun and convert it into direct current (DC). The direct current (DC) is sent through an inverter, which transforms it into an alternating current (AC). A bidirectional metre receives the alternating current. The bi-directional metre provides AC electricity to your residence, allowing all household appliances to operate. This metre transmits unconsumed and excess power to the grid. Whenever the exported units are needed again, the bidirectional metre imports them from the grid. Net metering refers to the process of exchanging power from the grid via a bidirectional metre.
Domestic on-grid solar system components
The solar panels of a residential solar grid are the most evident components. They've been mounted on the roof, facing south. When sunlight falls on these panels, they absorb that sunlight and convert it into electricity. The solar energy generated by the panels is direct current (DC). Because homes demand alternating current (AC), a solar inverter is required to convert direct electricity to alternating current.
Without the solar inverter, the complete solar system would have been an unrealistic concept. The solar inverter is responsible for converting DC to AC. This process is necessary since it is the only means to transform electricity generated by an on-grid solar panel into a useful form (AC) capable of powering domestic equipment.
Solar mounting structures
These are the framework that supports solar panels. They must be of excellent workmanship in order to endure high winds during storms and cyclones while also supporting the weight of the solar panels. The best solar installation structures originate in precision labs. They are rust-proof since they are hot-dip galvanised in steel. They must be constructed to withstand the wind speeds specified for the installation site and building height.
These include the AC and DC cables necessary to interconnect solar panels and link other sections to make the full solar grid function. DC combiner boxes and AC combiner boxes are the subsequent essential accessories needed to set up an on-grid solar system. A DC combiner box functions similarly to an isolation box. All wires transferring DC electricity from the panels are separated in this box. DC power from the panels can reach 1000 volts or more. It's hazardous, which is why a DC combiner box is required. This box supplies direct power to the solar inverter, which generates alternating current. This AC electricity is delivered into an AC combiner box. After the full on-grid solar system is installed, earthing is completed with earthing strips and cables.

Net metering on on-grid solar system
The entire idea behind an on-grid solar system is based on the net metering principle. Net metering is most easily understood as a way for the discom to keep track of the power produced by the solar system, the electricity used, the power supplied to the grid, and the power imported. When the electricity bill accumulates at the end of each month, the readings from the bidirectional metre account for how many units were provided to the grid and how many units were withdrawn from the grid. If you provided more units than you utilised, the difference will be subtracted from your invoice. It will further minimise the bill. If you had to utilise more grid units than your solar plant produced, those units would be added to your account.
Benefits of using an on-grid solar system
There are three kinds of solar systems: on-grid, off-grid, and hybrid. Although there are three varieties, the on-grid solar system is the most popular and trusted by Indian homes. Naturally, an on-grid solar system for the house should provide some exceptional benefits.
