Solar On Grid PV System

A form of solar energy system that is connected to the electrical grid is referred to as a solar on-grid PV system, also known as a grid-tied or grid-connected PV system. Photovoltaic (PV) panels, inverters, and a connection to the utility grid make up this system.

A solar on-grid PV system operates as follows:

1. Multiple solar panels, which are composed of connected solar cells, form part of the system. These solar-powered panels produce direct current (DC) electricity from sunshine.

2. Inverter: An inverter receives the DC electricity produced by the solar panels. The main job of the inverter is to change the direct current (DC) electricity into alternating current (AC), which is the kind of electricity utilised in buildings like homes and offices.

3. Grid connection: Your electrical service panel receives the AC electricity generated by the inverter, which is then used to power your electrical loads. A bi-directional metre is used to feed any extra electricity generated by the solar system back into the utility grid when it is not needed at the moment.

4. The extra electricity you generate during the day is credited to your utility account under net metering. This implies that you effectively "sell" any excess electricity your solar system produces over what you use back to the grid in exchange for credits. When your solar system isn't producing enough electricity, such as at night or on cloudy days, you can use these credits to offset the electricity you use from the grid.

5. Grid backup: When your solar system isn't producing enough electricity, the utility grid serves as a backup source of power in a grid-tied system. This guarantees a consistent and dependable supply of electricity for your residence or place of business.

A solar on-grid PV system has the following advantages:

• Savings: If your system produces more electricity than you use each month, you can cut or do away with your monthly electricity expenses by producing your own electricity.
• Environmental impact: Using solar energy can help reduce greenhouse gas emissions and our reliance on fossil fuels because it is a clean, sustainable source of energy.
• Return on Investment: By saving energy, receiving possible government subsidies, and having the option to sell extra electricity back to the grid, investing in a solar PV system can yield a profit over time.
• Grid independence: Even though a grid-tied system depends on the utility grid for backup power, you may still drastically minimise your reliance on the grid and enjoy some degree of energy independence with it.
