Solar power generation system
Working Principle
When photovoltaic panels receive sunlight, they use the photovoltaic effect to directly convert solar energy into direct current (DC). The DC is then inverted and stepped up by an inverter into conventional alternating current (AC). Grid-connected systems directly feed into the power grid, while off-grid systems store excess electricity in batteries, which can release power for continuous supply on cloudy days or at night.
Application Fields
1. Residential rooftop solar: Installed on rural self-built houses or commercial building rooftops for self-consumption, with surplus electricity fed into the grid for sale.
2. Commercial and industrial solar power stations: Solar panels installed on factory roofs, warehouses, or greenhouse canopies to reduce corporate electricity costs.
3. Remote off-grid power supply: Independent power supply in areas without grid access, such as mountain villages, islands, or border outposts.
4. Public facility power supply: Powering streetlights, surveillance cameras, traffic signals, and meteorological monitoring equipment.
5. Large-scale ground-mounted power stations: Centralized solar power stations built in deserts or open areas, connected to the grid to deliver clean energy.
