Two paths for the next ten years: keep paying CSPDCL, or invest once in solar. The cumulative numbers side by side.

Anyone weighing solar in Raipur against staying on grid power is really comparing two cash-flow paths. This guide lays them side by side for a 3 kW household over ten years, with assumptions stated so that you can replace them with your own.
Quick answer: with the central subsidy, a typical 3 kW system breaks even around year three to four, after which the saving is almost pure gain; tariff increases improve the picture.
| Assumption | Value |
|---|---|
| System | 3 kW, tier-1 equipment |
| Price | Rs 1.80 lakh |
| Central subsidy | Rs 78,000 |
| Net cost | Rs 1.02 lakh |
| Annual saving, year one | Rs 33,000 |
| Tariff growth (flat case) | 0 per cent |
| Tariff growth (modest case) | 3 per cent a year |
| Maintenance | Rs 2,000 a year |
| Year | Net position, flat tariff | Net position, tariffs +3% a year |
|---|---|---|
| 0 | - Rs 1.02 lakh | - Rs 1.02 lakh |
| 1 | - Rs 0.71 lakh | - Rs 0.71 lakh |
| 3 | - Rs 0.09 lakh | - Rs 0.05 lakh |
| 4 | + Rs 0.22 lakh | + Rs 0.28 lakh |
| 7 | + Rs 1.15 lakh | + Rs 1.30 lakh |
| 10 | + Rs 2.08 lakh | + Rs 2.40 lakh |
These figures are simple arithmetic, ignoring degradation and an inverter replacement later. They show the shape: a few years to recover cost, then steady gain.
See solar payback calculation for the method.
| Item | Amount |
|---|---|
| System price | Rs 1.80 lakh |
| Loan at about 7 per cent over 5 years on Rs 1.5 lakh | EMI about Rs 2,970 |
| Down payment | Rs 30,000 |
| Monthly saving | About Rs 2,750 |
| Subsidy (Rs 78,000) used to prepay part of the loan | Reduces interest and EMI burden |
On this path, the monthly saving almost covers the EMI, so the household effectively pays little out of pocket each month and owns the system outright after five years.
Some households use more electricity once the bill falls, running an extra air conditioner or charging an EV. That is a benefit, not a loss, but it changes the arithmetic. Compare the extra comfort against the cost you would have paid on the grid for the same use. If you expect your consumption to rise, size the system accordingly, since net metering will offset it.
| Risk | Grid only | With solar |
|---|---|---|
| Tariff increases | Fully exposed | Largely hedged on the units you generate |
| Power cuts | Exposed | Same, unless hybrid with battery |
| Upfront cost | None | Net cost after subsidy |
| Equipment failure | None | Inverter risk; covered by warranty then replaced |

For a 3 kW home with the central subsidy, break-even is typically in about three to four years, sooner with the state top-up.
Solar still pays back; flat tariffs give the conservative case.
The inverter may need replacing once in 25 years, which belongs in a fuller comparison.
Small, and often just your own time or a low-cost cleaner.
If the EMI is close to the monthly saving, yes for many households.
