Solar On-grid system
A grid-connected photovoltaic power system, or grid-connected PV power system’s an electricity generating solar PV power system that is connected to the utility grid. A grid- connected PV system consists of solar panels, one or several inverters, a power conditioning unit and grid connection equipment.
How it Works
When sunlight hits the solar photovoltaic (PV) panels, electricity (or ‘solar energy’) is produced. The electricity then runs from the solar panels through an inverter. The inverter turns the power from direct current (DC) into alternating current (AC), which you can then use for electronic appliances in your home.
- Systems such as Net Metering and Feed-in Tariff which are offered by some system operators, can offset a customer’s electricity usage costs. In some locations though, grid technologies cannot cope with distributed generation feeding into the grid, so the export of surplus electricity is not possible and that surplus is earthed.
- Grid-connected PV systems are comparatively easier to install as they do not require a battery system.
- Grid interconnection of photovoltaic (PV) power generation systems has the advantage of effective utilization of generated power because there are no storage losses involved.
- A photovoltaic power system is carbon negative over its lifespan, as any energy produced over and above that to build the panel initially offsets the need for burning fossil fuels. Even though the sun doesn’t always shine, any installation gives a reasonably predictable average reduction in carbon consumption.
