Solar Questions, Answered
Everything you need to know before going solar in India
Why Go Solar in 2026
Four data-backed reasons why 2026 is the best year yet to go rooftop solar in India — and what it actually means for your electricity bill.
Electricity Costs Only Rising
Average Indian electricity tariffs have risen 38% over the past decade and show no signs of slowing. Locking in solar now hedges your household against future hikes — typical savings compound to ₹8–12 lakh over 25 years.
PM Surya Ghar Subsidies at Peak
The Central Government is offering up to ₹78,000 in direct subsidies under the PM Surya Ghar Muft Bijli Yojana. Add state-level top-ups (Maharashtra, Rajasthan, Gujarat offer additional ₹10,000–₹30,000) and payback periods shrink to under 4 years.
Solar Panel Costs at All-Time Lows
In 2026, premium 400W mono-PERC panels cost 60% less than they did in 2018. A fully installed 3kW rooftop system (with subsidy) now costs ₹1.2–1.8 lakh after government support — down from ₹2.5–3.5 lakh five years ago.
India Getting Sunnier — More Output
India averages 4.5–6.5 Peak Sun Hours per day — among the world's best for solar. Rajasthan, Gujarat, and Tamil Nadu households generate 20–35% more electricity per panel than homes in Germany or the UK, cutting payback significantly.
