For most families, the question is simple: what will solar do for my home and my bill? This guide to solar for home in Raipur answers it by family type and appliance load, shows the cost and saving at each size and walks through the decisions that matter, from system type to subsidy.
Quick answer: a typical three-bedroom home using 300 to 400 units a month needs about 3 kW, costs about Rs 1.65 to 1.90 lakh before subsidy and saves Rs 2,400 to 3,000 a month.
| Household | Monthly units | System | Panels (540 Wp) | Roof area |
|---|---|---|---|---|
| Couple, fans and fridge | 100 - 200 | 1 - 2 kW | 2 - 4 | 10 - 20 sq m |
| Small family, one AC | 250 - 350 | 2 - 3 kW | 4 - 6 | 20 - 30 sq m |
| Family of four, two ACs | 350 - 500 | 3 - 4 kW | 6 - 8 | 30 - 40 sq m |
| Large home, 3+ ACs, pump | 500 - 700 | 5 kW | 10 | 50 sq m |
| Home with EV and many ACs | 700+ | 6 - 8 kW | 12 - 16 | 60 - 80 sq m |
Use your own twelve-month average, not a single summer bill. See solar size by electricity bill.
| System | Before subsidy | Net after central | Annual saving |
|---|---|---|---|
| 2 kW | Rs 1.2 - 1.4 lakh | Rs 60,000 - 80,000 | Rs 19,000 - 24,000 |
| 3 kW | Rs 1.65 - 1.90 lakh | Rs 87,000 - 1.12 lakh | Rs 29,000 - 36,000 |
| 5 kW | Rs 2.6 - 3.0 lakh | Rs 1.8 - 2.2 lakh | Rs 48,000 - 60,000 |
Air conditioners and geysers are the largest loads. A 1.5 ton inverter AC can use 8 to 12 units over eight hours; see can solar run an AC. A solar water heater can replace most geyser use; see solar water heater in Raipur. Efficient LED lighting and five-star appliances reduce the system you need.
Up to Rs 78,000 central subsidy for 3 kW and above, plus a reported state top-up. Read PM Surya Ghar Yojna in Raipur and solar subsidy in Raipur.
Your bill falls to fixed charges plus a small net amount in heavy months. You become a producer, with an inverter app showing daily generation. Maintenance is light. You may also find that you use appliances more freely because each unit is cheaper. If you expect an EV, plan capacity for it; see solar and EV charging at home.
A family of four in Avanti Vihar uses 450 units a month with two ACs and pays about Rs 3,800. They choose 4 kW, pay about Rs 2.2 lakh, receive Rs 78,000 and net about Rs 1.4 lakh. Annual saving is around Rs 40,000, so payback is about three and a half years. After that, the saving is almost pure gain for two more decades.
| Step | Benefit |
|---|---|
| Switch to LED lighting and five-star appliances | Cuts the system size you need |
| Run heavy appliances by day when practical | Uses solar directly |
| Service air conditioners and set 25 - 26 degrees | Reduces cooling load |
| Add a solar water heater | Removes a large geyser load |
| Plan for an EV charger | Adds capacity before you buy the car |
Independent houses have the simplest process. Duplexes and row houses need care with shared walls and shade. Flats need society consent. Rented homes need the owner's written consent. Read solar installation in Raipur: bungalow vs flat to see how each case differs.
The simplest way to size solar for a home in Raipur is to start from your monthly units. Divide your average monthly units by about 120 to estimate the kilowatts you need.
| Monthly bill (at about Rs 7 per unit) | Approx. units | Suggested system | Central subsidy (eligible homes) |
|---|---|---|---|
| Rs 1,500 | About 215 | 2 kW | Rs 60,000 |
| Rs 2,500 | About 355 | 3 kW | Rs 78,000 |
| Rs 3,500 | About 500 | 4 - 4.5 kW | Rs 78,000 |
| Rs 5,000 | About 715 | 5 - 6 kW | Rs 78,000 |
For most homes, a 3 to 5 kW grid-tied system sized from twelve months of bills; read 3 kW, 5 kW or hybrid.
A 3 kW system typically saves about Rs 2,500 to 3,000 a month; test your numbers in the savings calculator.
Only if power cuts are frequent or long; otherwise grid-tied costs less.
