Solar energy systems play a crucial role in achieving clean energy goals, with Off-grid PV Systems and On-grid Photovoltaic Systems being important solutions for different application scenarios. This article will delve into the differences between these two types of systems to better understand their characteristics and suitable scenarios.
Off-grid PV Systems are completely independent from the electricity grid. They use solar energy to power the load, converting solar energy into electrical energy during the day through solar panels while charging batteries for backup power. If necessary, a backup generator can be added. Such systems perform excellently in remote areas with no grid access.
When urban electricity demand is high, causing power shortages or instability in certain areas, Off-grid PV Systems become particularly important. They do not depend on the city's electric grid and can provide stable and reliable uninterrupted power supply for households, offices, industries, agriculture, power communication, transportation, travel, and data centres among other fields.
Highlights:
A completely off-grid power solution
Converting solar energy into electrical energy during the day
Directly powering the load
Powering the load from the battery
On-Grid Photovoltaic Systems are a way to reduce electricity bills, connecting to the grid and converting solar radiation into electricity during the day through solar modules. The system includes a on-grid photovoltaic inverter, providing electricity to the load or selling excess electricity back to the grid through net metering or feed-in tariff schemes.
Highlights:
Converting solar energy into electrical energy during the day
Directly powering the load
Selling excess electricity to the grid
The difference between off-grid and on-grid photovoltaic systems is that Off-grid PV Systems cannot feed electricity back into the grid. Therefore, Off-grid PV Systems are mainly used in remote areas with unstable or no grid access. In contrast, on-grid photovoltaic systems focus on reducing electricity bills and achieving economic returns by selling excess power back to the grid.
Considering demand, geographical location, and economic benefits, choosing the right type of photovoltaic system will provide the greatest benefits for various scenarios. Whether it's achieving independent power supply or reducing electricity bills, photovoltaic systems make a positive contribution to the promotion of sustainable energy.
