An on-grid photovoltaic system is a solar energy system that is directly connected to the public electrical grid. Unlike an off-grid system, it does not require batteries to store the generated energy, as the unused electricity is fed back into the grid, and any energy shortfall (e.g., at night or on cloudy days) is drawn from the grid.
The main components of an on-grid system are:
Solar panels: Capture solar energy and convert it into direct current (DC) electricity.
Inverter: Converts the direct current (DC) electricity generated by the panels into alternating current (AC), which is the form used in homes and the electrical grid.
Bidirectional meter: Measures the amount of electricity consumed from the grid and the amount sent back to the grid. In some cases, users may receive compensation for the energy they send to the grid, a process known as net metering.
Electric grid: The public grid to which the system is connected, allowing both consumption of electricity and the feeding of excess solar energy back to the grid.
This type of system is ideal for those who have access to the electrical grid and wish to use solar energy to reduce their electricity bills but do not require energy storage. Additionally, it allows users to contribute to the grid and potentially benefit from credits or compensation.
