Is This Kit Right for You?

Suryam Max is for 3–4 BHK homes with monthly bills of Rs 5,000–10,000. If you have 2 or more ACs running most of the year, the 5 kW system typically eliminates the majority of your grid consumption.

Monthly bill: Rs 5,000–10,000
Home: 3–4 BHK
Available roof: 300–400 sq ft
Goal: Nearly eliminate your electricity bill, not just reduce it

The hybrid inverter option

Suryam Max can be configured with a hybrid inverter (+Rs 35,000–50,000) that gives you 3–4 hours of backup during power cuts — without a separate battery unit.

Customer Stories

In Kerala, power cuts during monsoon are real. The hybrid inverter was the deciding factor for me — 3–4 hours of backup without a separate battery. Ten months in, saving Rs 4,200 a month and never worried about power cuts. The 10 panels take up about half our terrace. Still plenty of room for everything else.

BrightSun spent a full day just on the roof survey. The system generates 32–35 units on sunny days. Monthly bill dropped from Rs 9,500 to under Rs 1,500. Payback will be under 3 years.

Questions

Frequently Asked Questions

Yes. The PM Surya Ghar subsidy is capped at Rs 78,000 for systems of 3 kW and above. A 5 kW system gets the same maximum subsidy as a 3 kW system.
For an additional Rs 35,000–50,000, the standard string inverter is replaced with a hybrid inverter. This allows you to add a battery later. Even without a battery, a hybrid inverter gives limited backup capability (enough for lights and fans for a few hours). Your installer explains the exact backup configuration.
A 5 kW system generates roughly 20–25 units daily in peak summer. If you are running 2 ACs simultaneously, you may still draw some grid power during peak afternoon usage. The calculator and your site survey will give you the exact picture for your consumption pattern.
