The Generation Guarantee

A Written Minimum. Every Year, Every System.

One promise, across every capacity — 3kW to 10kW and beyond.

Most solar companies give you an "estimate" and walk away. Every TerraEnerG guaranteed-generation system gives you a written minimum you can hold us to — fall short, and we pay you for every missing unit. Your system is built to do better than this number; the guarantee is the floor, not the target.

The Promise

What Exactly Are We Guaranteeing?

Simple numbers, no fine print games — find your capacity below.

CapacityGuaranteed Units/Year (Min)Total Over 5 Years
3kW3,60018,000
5kW6,00030,000
8kW9,60048,000
10kW12,00060,000

If we fall short of your capacity's guaranteed number in any year: ₹8 per missing unit, paid automatically.

A real example, not just a promise

Say your 5kW system generates 5,800 units in a year instead of its guaranteed 6,000. You get ₹8 × 200 = ₹1,600, credited to you automatically between January and March. No forms, no claims process — we track it, we pay it.

How It's Measured

How Is Generation Measured?

Your generation is tracked through the data logger and inverter attached to your system. If a few days of data are missing — say, due to an internet or logger issue — we don't just skip those days. We fill the gap using the average generation from the rest of that month, so your reading stays fair and accurate.

Example: if a month generates 300 units total and 2 days of data are missing, we take the average across the remaining 28 days — 11 units/day — and credit that for the missing days too. Final reading: 322 units for the month.

Start Date

When Does the Guarantee Start?

Your 5-year guarantee period begins the day your system is synchronized to the grid — not the day you sign the order, not the day of installation. From that date, five full annual cycles are covered.

Fair Terms

When Doesn't the Guarantee Apply?

We stand behind our systems 100%. But some things are genuinely outside anyone's control — here's what those are, in plain language.

1Acts of nature and events beyond our control
Lightning, fire from external causes, flood, cyclone, severe weather, earthquake, natural disasters, war, civil disturbance, or government restrictions.
2Outside damage
Rodent, bird or animal damage, theft, vandalism, accidental impact, or pest damage.
3New shading after installation
New trees, new buildings, neighbouring construction, water tanks, satellite dishes, or anything else that blocks sunlight after your system is installed.
4Roof or structural changes
Roof reconstruction, civil work, waterproofing, structural changes, or moving the system yourself.
5Unauthorized changes by anyone else
If the system is modified, repaired, rewired, or relocated by anyone outside TerraEnerG, or connected to equipment we haven't approved.
6Misuse
Deliberately switching off the system, disabling equipment, or blocking our access for maintenance and inspection.
7Grid and utility issues
BESCOM outages, grid instability, meter issues, net-metering restrictions, or delays outside our control.
These categories are covered in full detail in your signed installation agreement, which sets out the exact terms and conditions for your system.
Beyond Year 5

The 5-Year Guarantee Ends. Your System Doesn't.

Solar panels lose a little output every year — that's normal ageing, not a flaw. So every 5 years, at AMC renewal time, we re-guarantee your generation at a number 5% lower than your original guaranteed figure. Renew your AMC, and your guarantee renews with it — fresh, in writing, for another 5 years.

CapacityYrs 1–5Yrs 6–10Yrs 11–15Yrs 16–20Yrs 21–25

8kW9,6009,1208,6408,1607,680
10kW12,00011,40010,80010,2009,600

These numbers become a real guarantee again each time you renew your AMC. Skip a renewal, and the number simply becomes a projection instead — not a broken promise, just no longer backed by a payout.
