Bill band guide
A ₹500 monthly bill is below the threshold where grid-tied rooftop solar typically pays back in a reasonable timeframe — even with PM Surya Ghar CFA. We give honest not-yet advice, not a hard sell.

Installers love quoting “free electricity” to every homeowner. Sealix advises independently: we are not your installer. At ~₹500/month, the maths usually says wait — unless your bill is about to jump sharply (new AC, EV, growing family) or you have a non-financial reason to install now. Run the free home check with your exact bill amount anyway; we will tell you honestly.
At typical domestic slab tariffs (varies by state), ₹500/month often implies:
This band sits well below the inflection point where solar economics start to work for most Indian homes.
Central residential CFA is commonly ₹30,000 / ₹60,000 / up to ₹78,000 for eligible 1–3 kW+ systems. At ~₹500/month, a 1 kW plant might qualify for ~₹30,000 assistance — but net out-of-pocket is still substantial relative to monthly savings. Full walkthrough: PM Surya Ghar guide.

Usually not yet. At this level the arithmetic says wait, unless your bill is about to rise sharply because of a new air conditioner, an electric vehicle or a growing family, or you have a non-financial reason to install now. This band sits well below the point where solar economics start to work for most Indian homes.
Four reasons compound. Monthly savings are small, so even a well-performing 1 kW plant saving ₹300 to ₹500 against a net cost after assistance of ₹40,000 to ₹60,000 implies eight to fifteen years or more. Installers have a floor on project size, and small systems cost more per kW than 3 kW plants. Process overheads such as feasibility, net metering and society approval cost the same whether you save ₹500 or ₹3,000. And assistance of around ₹30,000 at 1 kW helps without making a low-bill home cash-positive quickly.
Track your bill for twelve months and note the seasonal peaks. Improve efficiency first through LED lighting, efficient fans, sensible fridge placement and geyser timing, since these cost far less per unit saved. Then re-run the numbers when your bill crosses roughly ₹1,000 to ₹1,500 a month, and again if it climbs toward ₹3,000.
Yes, four. If your bill is rising fast because you are adding an air conditioner, vehicle charger or water pump and expect ₹500 to become ₹2,000 or more within a year. If a narrowly targeted state package with zero upfront cost genuinely covers your cohort. If you have a non-financial priority and will keep the home fifteen years or more. Or if ₹500 is an annual average masking ₹2,000-plus summer months, in which case size from the annual pattern rather than the low month.
No. Oversizing on a low bill wastes money, because capacity beyond what you consume earns the weakest possible return and capacity beyond 3 kW attracts no extra central assistance in any case. A vendor pushing 3 kW at this consumption level is sizing to the subsidy ceiling rather than to your household.
No. A standard grid-tied system produces nothing during an outage, because the inverter must disconnect when it stops sensing the grid. Backup requires a hybrid inverter and battery storage, which is a separate purchase with its own replacement cycle, and it makes the economics harder rather than easier on a low bill.
