Overview of On-Grid Solar Systems
An on-grid (grid-tied) solar system connects to the main utility grid via a bi-directional (net) meter. A key advantage is the government subsidy for rooftop on-grid systems: ₹30,000 – ₹78,000 depending on system capacity.
| Example Price Demo (with subsidy) | City | Approx. Price |
|---|---|---|
| 3 kW on-grid | Bhopal | ~ ₹ 1,35,000 |
| 5 kW on-grid | Bengaluru | ~ ₹ 3,00,000 |
*Indicative as of 29 Apr 2025 for Blue 6ft variant. Final price varies by city, DISCOM, product variant, panel type, inverter, structure height, after-sales service, savings guarantee, roof height, etc.
What is an On-Grid Solar System?
An on-grid system connects to the utility grid through a net meter. Homes with reliable grid supply typically choose on-grid because it can support full household loads without batteries.
Core Components
- Solar panels
- Solar inverter
- Module mounting structures
- Bi-directional (net) meter
- Accessories: AC/DC cables, combiner boxes, conduit, LA, MC4
Mounting Structures
Standard-grade, prefabricated, hot-dip galvanized structures for rust protection & cyclone-grade wind resilience.
- Withstand high wind speeds
- Rust resistance with HDGI coating (~80 μm)
Net Metering
Replaces the regular meter to track import and export units. Bills reflect net usage.
- Export more → bill reduces via credits
- Import more → added to bill
How Does an On-Grid Solar System Work?
- Solar Energy → DC: Panels generate DC based on irradiance & efficiency.
- Inverter (MPPT): Converts DC to AC (50 Hz) & tracks maximum power.
- Net Meter: Records import/export for accurate net-billing.
- Home Loads: Daytime loads run on solar AC first, reducing grid import.
- Export Surplus: Excess flows to grid, earning credits per policy.
- Import When Needed: At night/low sun, draw from grid (using credits first).

FAQs
Does on-grid solar need a battery?
No. That’s a major advantage — no battery means lower cost and less maintenance vs hybrid/off-grid.
Do solar panels work at night?
Panels generate only in sunlight. At night, on-grid systems draw from the grid, using available net-meter credits first.
What’s the difference between on-grid and hybrid?
Hybrid connects to grid + batteries; on-grid connects to grid only (no batteries).
What is the on-grid solar panel price in India?
It varies by panel/inverter tech and the factors listed above. For example, MonoPERC half-cut panels are ~₹24/W (indicative).
