How many kilowatts your roof takes, what the subsidy actually covers, and how many years until it has paid for itself. Before a salesman visits.
Sized on sun hours for this district. Real numbers need your last twelve months of bills and a look at the roof — shading changes everything.
Panels carry a 25-year performance warranty. This is what the cumulative saving looks like against what you paid, at the settings above.
A home paying ₹1,200 a month and a workshop paying ₹40,000 need different things. Each is sized from actual consumption, not from a brochure.
On-grid systems sized to your last year of bills, with net metering so surplus units go back to the grid.
Larger on-grid systems where the daytime load is the whole reason solar makes sense.
For areas with long cuts, where solar has to keep essentials running rather than only cut the bill.
Solar pump sets under the state scheme, with the paperwork handled end to end.
The central rooftop scheme pays a fixed amount by system size for homes, credited after installation and inspection. It is not a discount we hand you on day one, and any installer who shows it that way is quoting a number you will not see for weeks.
Housing societies and commercial rooftops are on different tracks entirely. Those are quoted separately rather than folded into a headline figure.
Illustrative slabs for this concept. Your exact entitlement depends on the scheme in force on the day of application, and it is confirmed in writing before you commit to anything.
One photograph of the last bill and the roof is enough for a first estimate of size and payback.
An on-site visit to measure usable area, check shading through the day and confirm the structure takes the mounting.
Subsidy and net-metering applications filed, then installation over two to three days once approval lands.
MSEDCL inspection, meter change, commissioning, and monitoring set up on your phone.
No, and this is the most oversold point in the industry. An on-grid system offsets units across the month; it shuts down during a cut for the safety of line workers. If the goal is running essentials through a cut, that needs a hybrid system with a battery, which costs more and is quoted separately.
Generation drops for those weeks. That is exactly why sizing is done on a full year of bills rather than a summer month. Surplus units banked in bright months carry the dip through net metering.
Roughly 65 to 70 square feet of clear, unshaded roof per kilowatt. A water tank, a parapet shadow or a neighbour's wall can take out more usable area than people expect, which is why the assessment happens on site.
Panels need cleaning and an annual check. Two cleanings a year are included for the first five years. The inverter carries its own manufacturer warranty, typically five to ten years, and is the part most likely to need attention first.
That single page carries your yearly consumption, which is what decides the system size and the payback. The roof visit comes after.
