On-Grid Solar Systems

On-Grid / Grid-Tie Solar

How On-Grid Solar Works

An On-Grid solar system — also called a grid-tied or grid-connected system — is directly connected to your local utility grid. Solar panels generate DC electricity, which the inverter converts to AC power for your home or business. Any excess power is exported to the grid and you receive credits on your electricity bill through Net Metering.

This is the most cost-effective type of solar installation because it doesn't require expensive battery storage. With TANGEDCO's net metering policy, every unit you export earns you a credit at the feed-in tariff rate, significantly reducing your annual electricity bill.

Why On-Grid

Top Benefits of On-Grid Solar

💰

Lowest Cost Option

No battery storage required — makes on-grid the most affordable solar system type with the shortest payback period of 3–4 years.

🏦

Earn from Net Metering

Export surplus power to TANGEDCO grid and earn credits @ ₹3.5–₹4.5 per unit, dramatically reducing your annual electricity bill to near zero.

🎁

Government Subsidy

Avail PM Surya Ghar subsidy up to ₹78,000 for residential systems up to 3 kW, and additional TANGEDCO state subsidies for larger installations.

🌍

Reduce Carbon Footprint

A 5 kW system prevents approximately 6 tonnes of CO₂ emissions annually — equivalent to planting 280 trees every year you use solar energy.

📈

Increase Property Value

Studies show solar installations increase property value by 3–5%. A 5 kW rooftop system can add ₹3–5 lakh to your home's resale value.

🔧

Minimal Maintenance

On-grid systems have no batteries to replace, reducing long-term maintenance costs. A simple quarterly cleaning keeps output optimal for 25+ years.
