On-grid solar: export surplus, import when needed
On-grid systems use solar inverters tied to your utility supply. When generation exceeds load, energy flows to the grid; at night or on cloudy hours, you draw from the grid. Savings depend on tariff slabs, export rules, and plant performance.
How net metering helps
A bidirectional meter records import and export. Billing is based on net consumption over a defined period—subject to your state's regulations and DISCOM procedures.
During a grid outage
Standard on-grid inverters shut down for safety when the grid fails—so rooftop solar alone won't power your home during blackouts unless you add approved backup or storage solutions.
