Bill band guide
A ₹1,500 monthly bill is a common inflection point. Solar can work — but payback stretches unless your slab tariff, sun exposure, and CFA band align. We give honest yes / maybe / not yet advice, not a hard sell.

Installers love quoting “free electricity” to every homeowner. Sealix advises independently: we are not your installer. A ~₹1,500/month bill usually maps to roughly 250–350 units depending on DISCOM slabs and fixed charges — enough to consider solar, but not always enough for fast payback. Run the free home check with your exact bill amount.
At typical domestic slab tariffs (varies by state), ₹1,500/month often implies:
This band is above the “bill too low for solar” floor — but payback may run 5–8+ years unless CFA and slab savings stack well.
Many homes in this band land on a 2 kW plant first — enough CFA to help, without overspending on capacity you cannot use. See 3 kW vs 5 kW before upsizing.
Central residential CFA is commonly ₹30,000 / ₹60,000 / up to ₹78,000 for eligible 1–3 kW+ systems. At ~₹1,500/month, you may qualify for assistance but might not need — or justify — a full 3 kW+ system to capture the ₹78,000 ceiling. Full walkthrough: PM Surya Ghar guide.

It can be, but it is a genuine judgement call rather than an obvious yes. This band sits above the floor where bills are too low for solar, yet payback may still run five to eight years or more unless central assistance and slab savings stack well together. It works best where you pay a steep rate on your top block of units, have a clear shade-free terrace, and expect your bill to rise.
Roughly 250 to 350 units a month, depending on your DISCOM's slabs and fixed charges. That typically reflects lights, fans, a fridge, pumps and one air conditioner or geyser. If two air conditioners push your summer average higher, size from the annual pattern rather than a single peak month.
Many homes in this band start at 2 kW, which attracts assistance in the region of ₹60,000 and offsets roughly 200 to 240 units a month in good sun. Move to 3 kW only if units consistently exceed about 300 a month and the roof allows it. Going larger to capture the full ₹78,000 ceiling is not automatically worthwhile if you cannot use the output.
Wait if your bill is below roughly ₹1,000 a month, since payback often exceeds ten years even with assistance. Also wait if you have heavy shade or a shared terrace with no clear approval path, if you are a tenant or expect a short stay, or if the quoted net cost after assistance still feels like a stretch. Trust the arithmetic rather than the brochure.
Central residential assistance is commonly ₹30,000, ₹60,000 or up to ₹78,000 for eligible systems from 1 kW upwards. At this bill band you may well qualify for assistance, but you might not need or be able to justify a full 3 kW or larger system purely to reach the ₹78,000 ceiling, since the capacity beyond what you consume earns the least.
