FAQ: Rooftop solar cost in Bangalore
What is the rooftop solar cost in Bangalore after subsidy?
Published Eltron ranges include 3 kW at ₹1.8–2.4 lakh before subsidy and 5 kW at ₹2.1–2.7 lakh net after subsidy. Your final quote depends on your roof, structure, equipment and site survey.
How much PM Surya Ghar subsidy can a home get?
₹30,000 per kW up to 2 kW, plus ₹18,000 for the 3rd kW, capped at ₹78,000 for 3 kW and above, subject to scheme rules and approval.
Is rooftop solar worth it after Gruha Jyothi?
It is mainly worth checking if your household regularly pays for electricity above the free entitlement or has a high monthly bill. Share your BESCOM bill so your usage in units, not just rupees, can be checked. If you regularly pay above that entitlement or have high daytime usage, solar is worth calculating, and we will tell you honestly if a smaller system makes more sense.
What is the payback period?
Eltron states a 2–4 year break-even. Your actual payback depends on system size, how much solar power you use directly, your tariff and generation at your roof, and we calculate it from your bill before quoting.
How long does installation take?
Timelines depend on roof readiness, materials, BESCOM feasibility and PPA steps, and net-meter scheduling. We will give you a timeline after your survey.
Which size should I choose — 3 kW or 5 kW?
Start with 12 months of bills, your daytime load and future plans such as AC, an EV or a home office. See our 3 kW guide and 5 kW guide, then confirm your size on a free survey.
