Off-grid means no connection to the grid. Solar panels charge batteries; inverter powers your load. Ideal for:
• Areas with frequent power cuts
• Remote locations with poor grid supply
• Loads that must run 24/7
You need: solar panels, charge controller, inverter, batteries.
On-grid solar
On-grid connects to the grid. Excess power is fed back; you get credits (net metering). No batteries. Ideal for:
• Stable grid supply
• Reducing electricity bills
• Offices, shops, factories
Sizing: based on roof area and monthly bill. 1 kW ≈ 100–120 sq ft. 5 kW can offset ₹5,000–8,000/month bill (Hyderabad rates).
