Most of our customers cut their electricity bill by 70 to 90 per cent. Here is the arithmetic behind that, for homes and for businesses.

Every solar quotation promises savings. Very few show the arithmetic. This guide does, using Raipur-specific generation figures and current CSPDCL tariffs, so you can sanity-check any quote you are handed.
The short version: a correctly sized system in Raipur typically removes 70 to 90 per cent of a household electricity bill, and pays for itself in three to four years once the PM Surya Ghar subsidy is counted.
The figure most people search for first is the 3kW solar system price in Raipur, because 3 kW is the size that extracts the maximum subsidy and suits the average family home. We break that down in full below, along with savings for every other system size and for commercial premises.
Savings start with generation, and generation starts with location. Raipur sits at roughly 21 degrees north with about 300 clear days a year and daily solar irradiance of 5.0 to 5.5 kWh per square metre.
In practical terms, 1 kW of well-installed solar capacity in Raipur produces around 4.0 to 4.5 units per day averaged across the year, or roughly 1,500 units annually. The same kilowatt in Delhi produces closer to 1,350 units, and in Kolkata closer to 1,250. That gap compounds across 25 years.
Seasonally, expect peak output in March, April and October, a dip through July and August when cloud cover is heaviest, and surprisingly good winter generation because panels are more efficient in cooler air. December mornings in Raipur are excellent solar weather.
Take a common Raipur household: a family in Shankar Nagar consuming 400 units a month, paying CSPDCL roughly Rs 3,200 including fixed charges and duty.
A 3 kW system generates about 360 to 400 units a month averaged over the year. That covers essentially the whole bill, leaving only the fixed meter charge of a few hundred rupees.
| System Size | Monthly Generation | Suits a Bill Of | Monthly Saving | Annual Saving |
|---|---|---|---|---|
| 2 kW | 240 - 270 units | Rs 1,500 - 2,200 | Rs 1,600 - 2,000 | Rs 19,000 - 24,000 |
| 3 kW | 360 - 400 units | Rs 2,500 - 3,500 | Rs 2,400 - 3,000 | Rs 29,000 - 36,000 |
| 5 kW | 600 - 675 units | Rs 4,000 - 5,500 | Rs 4,000 - 5,000 | Rs 48,000 - 60,000 |
| 10 kW | 1,200 - 1,350 units | Rs 8,000 - 11,000 | Rs 8,000 - 10,000 | Rs 96,000 - 1,20,000 |
These assume CSPDCL domestic slab rates with net metering in place, so exported units offset imported ones. Without net metering the numbers fall sharply, which is why we file that application for every customer - the process is explained in our installation timeline guide.
The 3kW solar system price in Raipur is the single most searched figure in Chhattisgarh solar, so here it is in full.
| Line Item | Amount |
|---|---|
| System cost (quality tier-1 equipment) | Rs 1.65 - 1.90 lakh |
| PM Surya Ghar subsidy | - Rs 78,000 |
| Net cost to you | Rs 87,000 - 1.12 lakh |
| Annual saving | Rs 29,000 - 36,000 |
| Payback period | About 3 - 4 years |
| 25-year generation | Approx. 1,00,000 units |
| 25-year saving at today's tariff | Rs 7 - 8 lakh |
That last row is conservative, because it assumes tariffs never rise. CSPDCL rates have climbed steadily for two decades. Every future increase makes your solar system more valuable, not less - which is the opposite of how most purchases age.

Commercial solar installation in Raipur works differently and usually better. Businesses pay higher tariffs, consume most of their power during daylight hours when solar is producing, and can claim tax benefits households cannot.
Three factors drive the commercial case:
| Business Type | Typical System | Annual Saving | Payback |
|---|---|---|---|
| Retail showroom | 15 kW | Rs 1.8 - 2.2 lakh | 4 - 5 years |
| School or college | 30 kW | Rs 3.6 - 4.4 lakh | 4 - 5 years |
| Hospital or nursing home | 50 kW | Rs 6 - 7.5 lakh | 4 - 5 years |
| Hotel | 75 kW | Rs 9 - 11 lakh | 4 - 5 years |
| Manufacturing unit | 200 kW | Rs 24 - 30 lakh | 3.5 - 4.5 years |

Three benefits rarely appear in a quotation but are real:
Five errors account for most disappointing solar outcomes in Raipur:
Generic calculators are guesswork. Ours is not. We take your last twelve CSPDCL bills, measure your actual shadow-free roof area, model shading across the day, apply Raipur-specific irradiance data and produce a month-by-month generation projection against your real consumption.
You get a figure for expected annual saving, payback period and 25-year return before you spend anything. If your roof cannot deliver a sensible return, we will say so rather than sell you a system anyway.
Yes, genuinely. Raipur gets around 300 sunny days a year and solar irradiance of 5.0 to 5.5 kWh per square metre daily - better than Delhi, Lucknow or Kolkata. Systems here are designed to make the most of that, so you get strong clean generation year-round rather than only in summer.
Most of our customers see their electricity bill fall by 70 to 90 per cent, and frequently around 80 per cent. A correctly sized 3 kW system in Raipur saves roughly Rs 2,400 to Rs 3,000 a month. Send us your current bills and we will produce a personalised estimate.
A quality 3 kW grid-tied system costs roughly Rs 1.65 to Rs 1.90 lakh before subsidy in Raipur. After the PM Surya Ghar subsidy of Rs 78,000, your net cost falls to about Rs 87,000 to Rs 1.12 lakh.
For a subsidised residential system, typically 3 to 4 years. For commercial installations without subsidy but with accelerated depreciation, typically 4 to 5 years. After that, generation is effectively free for the remaining 20-plus years of panel life.
Yes, at reduced output - usually 30 to 50 per cent of peak on heavily overcast days. Raipur's monsoon lasts three to four months, and the eight to nine months of strong sun on either side more than compensate. Annual figures, not monsoon figures, are what matter.
Solar is not a gadget purchase, it is a prepaid electricity contract. You pay once for twenty-five years of generation instead of paying CSPDCL monthly at a tariff that has never gone down. The only question worth answering is what your own roof would produce, and that takes one site visit to settle.
