on-grid solar power plant uses high-efficiency photovoltaic (PV) panels to convert sunlight into clean electricity. The generated power is directly consumed by homes or businesses, and any excess electricity is fed into the public grid. Through net metering, users can earn credits for surplus power supplied to the grid. Unlike off-grid systems, this setup does not require batteries, as the grid itself acts as a virtual battery, ensuring uninterrupted power supply even when solar production is low. A 4kW system is ideal for small households, shops, and offices, helping reduce monthly electricity bills while promoting eco-friendly energy usage.
