~₹1,500/month electricity bill — when rooftop solar fits (and when it does not)

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.

What ₹1,500/month roughly means

At typical domestic slab tariffs (varies by state), ₹1,500/month often implies:

• ~250–350 kWh/month average consumption
• Often a mix of lights, fans, one AC or geyser, fridge, and pumps
• Sometimes two ACs in summer pushing the average up — size from annual pattern, not one peak month

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.

When solar often makes sense at ~₹1,500/month

• High marginal slab — you pay steep rates on the top block of units; solar offsets expensive kWh first
• Clear south-facing terrace — minimal shade, room for 2–3 kW
• Eligible for PM Surya Ghar CFA — commonly ₹30,000–₹60,000 at 2–3 kW bands via pmsuryaghar.gov.in
• Bill trending up — new AC, EV charger, or growing family pushing units higher each year

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.

When to wait or skip

• Bill under ~₹1,000/month — payback often exceeds 10 years even with subsidy
• Heavy shade or shared terrace with no NOC path — process cost exceeds savings timeline
• Tenant or short-term stay — you will not capture payback
• Quoted net cost after CFA still feels like a stretch — trust the maths, not the brochure

PM Surya Ghar CFA at this bill band

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.

Typical sizing at ~₹1,500/month

Rough guide only — your DISCOM slab and consumption pattern override any rule of thumb:

• 2 kW — common starting point; CFA ~₹60,000 band; offsets ~200–240 kWh/month in good sun
• 3 kW — if units consistently exceed ~300/month and roof allows; targets full CFA ceiling

Compare with the ₹3,000/month bill guide if your bill is climbing.
