Before buying solar in Raipur, spend a weekend finding where your electricity actually goes. Every unit you save is a unit you do not have to generate, which can mean a smaller, cheaper system.
Quick answer: list your appliances, read twelve months of bills, fix the biggest wastes, then size solar to what is left.
| Step | Action |
|---|---|
| 1 | Collect twelve months of bills and total the units |
| 2 | List every appliance with watts and daily hours |
| 3 | Mark the top three users (usually AC, geyser, fridge) |
| 4 | Service ACs and set them to 25 - 26 degrees |
| 5 | Replace old bulbs and pumps with efficient ones |
| 6 | Check the fridge door seal and defrost |
| 7 | Shift flexible loads such as pumps and washing to daytime |
| 8 | Recalculate monthly units and size solar from the new figure |
Households often find a tenth to a quarter of their use is avoidable, though results vary. Cutting 60 units a month from 360 cuts the solar need from about 3 kW to 2.5 kW, which lowers upfront cost. See efficiency before solar.
Give your installer the audit and the twelve bills. A good surveyor will check the numbers against your roof and sanctioned load, then size the system. This keeps the quotation honest and avoids oversizing.
| Appliance | Typical watts | Hours per day | Units per month (approx.) |
|---|---|---|---|
| Ceiling fan | 60 | 10 | 18 |
| LED bulb | 9 | 6 | 1.6 |
| 1.5 ton AC (inverter) | 1,200 | 8 | 290 |
| Refrigerator | 150 | 24 (cycling) | 40 |
| Water pump | 750 | 1 | 22 |
| Geyser | 2,000 | 1 | 60 |
| TV and set-top | 100 | 5 | 15 |
Multiply watts by hours and by 30, then divide by 1,000 to get units. Use your actual appliances; the figures above are typical ranges only.
Look at units per month rather than the rupee total. Note the seasonal peaks, usually April to June when air conditioners run. Solar sizing should lean towards the annual average, not the single worst month. If your usage has jumped recently because of a new AC, size for the new level.
A written audit lets the surveyor focus on your roof rather than guessing your load. It also protects you from oversized systems. Pair this guide with kW vs kWh vs kWp to understand the sizing arithmetic.
