Most solar companies sell you a list: panels, inverter, structure, cables, installation. We think you should be buying something simpler — performance.
TerraEnerG 8K is one complete solar product. We design it, install it, and support it — so you don't have to pick components or compare brands. We take full responsibility for how well it performs.
9,600 units is our minimum guarantee for each of the first 5 years. Your system is designed to generate more — this is the floor, not the target.
| Year | Guaranteed Generation |
|---|---|
| Year 1 | 9,600 units |
| Year 2 | 9,600 units |
| Year 3 | 9,600 units |
| Year 4 | 9,600 units |
| Year 5 | 9,600 units |
If your system makes less than 9,600 units in a year, you get ₹8 for every missing unit. Paid automatically, every year, between January and March. No forms, no claims.
Any repair or replacement your system needs in the first 5 years is completely free — parts and labour, zero cost to you.* This is a real commitment, not a marketing line.
*Excludes damage from events outside our control (lightning, flood, theft, and similar) — full terms on the Generation Guarantee page.
One price, paid once. There is no subsidy to apply for, no waiting for it to be credited, and no risk of it being rejected.
The PM Surya Ghar subsidy is capped at ₹78,000, however large the system. It also requires DCR panels, which typically cost about ₹12,000 more per kW. The bigger the system, the more that premium outweighs the subsidy.
The ₹12,000 per kW difference is typical, not fixed, and panel prices change. At 5 kW and below, subsidy usually works out better, which is why TerraEnerG 3K and 5K are subsidy systems.
Compare with TerraEnerG 8K, with subsidy →It depends on how you use the power. Units used at home offset your ₹7 tariff. Units exported earn ₹3.8. BESCOM no longer banks units, so size for your own use.
| Scenario | Units a year | Worth a year | Payback |
|---|---|---|---|
| Guaranteed minimum, all used at home | 9,600 | ₹67,200 | ~5.9 years |
| Typical output, all used at home | 10,560 | ₹73,920 | ~5.4 years |
| Guaranteed minimum, all exported | 9,600 | ₹36,480 | ~10.9 years |
Estimates, not guarantees. Typical output is 110 units per kW per month, the average across about 30 of our installations. Assumes a flat ₹7 tariff and no panel degradation, and ignores financing costs.
Work out the right size and payback for your bill →Installation is just the start. For 5 years, we watch, maintain, and repair your system — and any repair or replacement it needs is completely free to you.* We catch problems before you'd even notice them.
Solar panels slowly generate a little less power each year — that's normal. So every 5 years, we lower the guaranteed number by 5% and guarantee it fresh, for another 5 years. Renew your AMC, and your generation guarantee renews with it. Skip the renewal, and the guarantee simply doesn't continue — the numbers below become long-term projections instead.
These numbers become guaranteed again each time you renew your AMC. Without renewal, they're projections, not guarantees. Actual generation depends on sunlight, shading, and site conditions.

TerraEnerG 8K is priced at ₹3,99,000 all-inclusive. It is a non-subsidy system, so there is no subsidy to apply for and the price is what you pay.
TerraEnerG 8K guarantees a minimum of 9,600 units per year for the first 5 years. Across our installations, systems average about 110 units per kW per month, which for 8 kW is roughly 10,560 units a year.
The PM Surya Ghar subsidy is capped at ₹78,000 and needs DCR panels, which typically cost about ₹12,000 more per kW. At 8 kW, that extra panel cost (about ₹96,000) is more than the subsidy. So 8K uses non-DCR panels and is priced lower upfront, with no subsidy wait and no risk of rejection. Actual panel prices vary.
Yes. Non-subsidy systems earn ₹3.8 per exported unit against ₹2.2 for subsidy systems. BESCOM does not bank units any more, so the best value still comes from using your own power.
If every unit offsets a ₹7 tariff, about 5.9 years at the guaranteed 9,600 units, or about 5.4 years at a typical 10,560 units. These are estimates that assume a flat tariff and no degradation. They are not a guarantee.
It is sized for homes using about 800–850 units a month. As a guide, each ton of AC adds about 120 units a month at 8 hours a day, and an EV charged once a week adds its battery kWh × 30 ÷ 7. Our capacity guide works this out for you.
About 520–560 sq ft of shadow-free space.
Yes. The price is all-inclusive — system, design, installation and commissioning.
No. Your BESCOM meter is charged separately, at actual billed price from BESCOM.
Yes — financing up to 10 years is available through Jan Samarth or NBFC partners. See our financing options for a full comparison.
If your system generates less than 9,600 units in a year, you are paid ₹8 per missed unit, automatically, every year. See the full Generation Guarantee terms.
Generation continues on a projected basis (5% lower every 5 years), and AMC can be renewed in 5-year periods for continued maintenance support and a renewed guarantee.
