A complete 3 kW solar system for your home. Minimum 3,600 units guaranteed every year for 5 years — your system is built to do more. Plus zero maintenance cost for 5 years: any repair or replacement is completely free to you.*
*Excludes damage from events outside our control — lightning, flood, theft, and similar. Full list in the Generation Guarantee Terms.
Most solar companies sell you a list: panels, inverter, structure, cables, installation. We think you should be buying something simpler — performance.
TerraEnerG 3K 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.
3,600 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 | 3,600 units |
| Year 2 | 3,600 units |
| Year 3 | 3,600 units |
| Year 4 | 3,600 units |
| Year 5 | 3,600 units |
If your system makes less than 3,600 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.
Subsidy amount follows current government rules and your eligibility. It may change.
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.

Your electricity bill matters more than your house size. If your usage is around 300–350 units/month, a 3kW system is more than enough. If your usage is higher, take a look at our 5kW, 8kW and 10kW systems — or fill in the form and one of our executives will call you.
