The solar systems can be classified into 3 different types based on their grid-connections. They’re on-grid, off-grid and hybrid systems which are a combination of both. The on-grid solar power plant is a solar energy generation system. It is connected to the utility grid. The electricity produced by the system is routed to the grid. From where it’s used to operate various appliances. Whatever the extra electricity is generated, it again sent back to the grid.
An on-grid solar energy system is very attractive than an off-grid system. In an on-grid system, solar energy is produced only the grid is out there. This power supply gets completely cut-off if in case the grid is out of reach. Hence, one must depend upon back-ups like DG sets for emergency power supply. The power shut down happens if in case of any safety and technical reasons are there.
How does the on-grid solar energy system work?
This system works in two-ways — the availability of electricity can be due to flow from the grid. Due to which the grid is connected to the user’s home and from the user’s home to the grid. This feature makes the on-grid system affordable and highly useful. The solar panels, installed on the user’s home are ‘tied’ to the grid. The solar panels convert sunlight into electric energy, which is Direct Current (DC). This current is then sent to an inverter. The solar inverter then converts the DC to Alternating Current (AC). Thus making it power the electrical items. This electricity is then routed to the grid where it is supplied for day to day use.
The grid-tied inverter additionally regulates the quantity and voltage of electricity. Which is enough for households, since all the energy generated is usually far more than a home needs to handle. A very important feature is a net meter. It’s a tool that records the energy supplied to the grid and therefore, the energy consumed. At the end of each month, the outstanding is recorded and the consumer is given a bill. This ‘converted’ power supply is then utilized by homes through the most electricity distribution panel.
Benefits of on-grid solar
- Zero Electricity Bills — Though the solar energy system is connected to the grid. The user has to pay only for the excess electricity he consumes. The bill generated on a monthly basis determines whether the buyer has any payments to be made. However, meanwhile, if the consumer utilizes less electricity. The excess supply is sent back in the grid.
- Easy maintenance — The on-grid solar energy system has the least number of parts along with simple installation. The elimination of batteries makes the maintenance quite easy.
- Passive income generation — With a connection to the grid, the consumer can charge. For the excess amount of electricity, he has generated. It eliminates your electricity bills. It also avails the value in cost benefits for the surplus electricity generated.
- On-grid solar systems are the foremost cost-effective and convenient to install. These are ideal systems for households. As the cost charged is often recovered easily. Through the extra power transmitted to the grid.
We have designed and installed a much on-grid power plant. Through which electricity is generated and used by the consumers. To Know More Click Here.
