Highlights

Why most Indian homes pick on-grid

The grid stores your surplus, the app shows every unit, and nothing costs less to install or run.

0 Batteries to buy or replace

The grid stores your surplus. Units you export by day come back at night through the net meter, so there is no battery bank to buy today and no replacement bill in year eight.

Hourly Generation you can read

Units produced, units exported and rupees saved, hour by hour, in the RePrime app — the same figures your DISCOM settles against, so the bill never surprises you.

Lowest Cost of the three types

Of on-grid, off-grid and hybrid, a grid-tied system costs the least to install and to run, and it is the type PM Surya Ghar subsidises by system size.

Questions

On-grid, answered

Battery or no battery, what happens at night, and what a system costs after subsidy. Anything else, our team answers on a call — no script, no pressure.

Talk to us

No. The grid plays the part of the battery — surplus units go out through the net meter during the day and you draw them back at night. That is what makes on-grid the cheapest of the three system types.

They do not generate after sunset. The net meter switches to import and the credits you built up during the day are used before you are billed for anything.

A hybrid system adds a battery and a hybrid inverter, so essential loads keep running through a power cut while surplus still gets exported. A plain on-grid system shuts down during an outage.

Indicatively ₹1.80 lakh for 2 kW to ₹6.50 lakh for 10 kW before subsidy, depending on the city. Subsidy then takes ₹30,000 to ₹78,000 off, plus a state top-up in Uttar Pradesh and Delhi.
