No jargon, no sales fluff. Plain-language guides to help you buy, finance, install and maintain solar with confidence.
Your rooftop solar feeds the grid during the day and draws from it at night. A bi-directional meter keeps score — you pay only for the net units you consume.
Illustrative — rates vary by state and tariff plan.
Four things matter more than the brand sticker: cell technology, efficiency, temperature coefficient and the fine print of the warranty.
TOPCon leads on efficiency and degradation; Mono-PERC is proven and value-priced; bifacial adds rear-side gain.
Higher efficiency means more power per square metre of roof — critical when space is tight.
A lower %/°C means the panel suffers less in India’s heat — check it on the datasheet.
Look for 25-year linear output warranty AND a product warranty that actually covers workmanship.
Most rooftop systems can be installed with almost nothing down. Here’s the money picture for 2026.
Central subsidy up to ₹78,000 for eligible residential rooftops up to 10 kW — paid directly to your bank.
Solar loans at 7–10% with tenures up to 10 years; many installers offer zero-down schemes.
Businesses can use group-captive structures to cut power costs 25–40% without capex.
