Tripura: Special-category CFA applies here — ₹85,800 at 3 kW instead of ₹78,000 — so the same system costs less in Agartala than in most states. The domestic slabs step up at 150 and 300 units, and generation dips in the monsoon, so size from the annual total rather than a summer month.

What each size needs and produces in Tripura
Output is 107 units per kW per month — Tripura’s own figure, not a national average — so a system here generates about 1284 units per kW over the year. Roof area assumes 90 sq ft of shadow-free space per kW.
| System | Roof needed | Units/month | Units/year | Sizing guide |
|---|---|---|---|---|
| 1 kW | 90 sq ft | 107 | 1284 | 1 kW guide |
| 2 kW | 180 sq ft | 214 | 2568 | 2 kW guide |
| 3 kW | 270 sq ft | 321 | 3852 | 3 kW guide |
| 5 kW | 450 sq ft | 535 | 6420 | 5 kW guide |
| 10 kW | 900 sq ft | 1070 | 12840 | 10 kW guide |
Annual output is the monthly figure × 12, so it assumes average weather. The weakest month is roughly 25% below the average — worth knowing before you size a system against a summer bill.
