Why most Karnataka homes that apply for solar never get it installed

Far more Karnataka households register interest in rooftop solar under PM Surya Ghar than ever end up generating a unit. The gap between the two is not apathy, and it is not the government withdrawing the money — the subsidy is real and it is still being paid. The gap is what happens in the middle: the months between "yes, I want solar" and a commissioned system with a net meter on the wall.

Almost every one of those plans died for a small number of ordinary, predictable reasons. Each of them is avoidable — but only if someone tells you about it before you sign, rather than after.

Where does a solar plan actually die?

Not at the decision. The decision is easy: your bill is high, your roof is empty, the government is paying part of the cost. Registrations are cheap and quick, which is exactly why so many exist.

It dies in the six weeks after. Here is what actually kills it, in roughly the order it happens.

The sanctioned-load mismatch, discovered late. Your BESCOM connection has a sanctioned load — often 1 kW or 2 kW on an older residential connection, set decades ago and never revisited. BESCOM will not sanction net metering for a system larger than your sanctioned load. So a homeowner signs for a 3 kW system, pays an advance, and only then learns that a sanctioned-load increase is required first: a separate application, a separate statutory cost, and weeks of waiting. It feels like a bait-and-switch even when nobody intended one. It is simply a number that should have been read off the bill on day one.

The quote that changes after the site visit. A price is quoted on the phone. An engineer visits. The price goes up — because of the roof height, the cable run, the structure, the "additional work". The homeowner, reasonably, stops trusting the number and starts collecting more quotes. Each new quote resets the clock. Many plans die in this loop, comparing figures that were never comparable.

The paperwork that stalls with no owner. A rooftop system in Bengaluru needs a PM Surya Ghar application, possibly a society or RWA NOC, sometimes a BBMP or BWSSB civil permission, and net-metering paperwork with your BESCOM sub-division. Any one of these can sit for weeks awaiting a clarification. When the homeowner is the one chasing sub-divisions between office hours, the plan does not get rejected — it just quietly stops.

The subsidy misunderstood. This is the big one, and we wrote a whole article about it. Many homeowners believe the ₹78,000 arrives as a discount on the invoice. It does not. It is credited directly to your bank account after commissioning and net metering. So you must fund the full amount first. Discovering that at the payment stage, rather than at the planning stage, kills plans outright.

Nobody accountable when something goes wrong. A panel underperforms. A cable frays. There is a leak near a mounting point. The homeowner calls the person who sold it; that person points at the installer; the installer points at the manufacturer. Nothing is technically anyone's fault, which is exactly the problem. Prospective buyers hear these stories from neighbours and quietly abandon their own plans.

The roof was never suitable. Sometimes the honest answer is no — heavy shading from a neighbouring building or a mature tree, an unsuitable structure, too little unshaded area. This is a legitimate reason to stop. It is only a failure when it takes three months and an advance payment to reach it.

What would have kept those plans alive?

Every failure above is an information failure, and information is cheap if you gather it in the right order.

The sanctioned load is printed on your bill. Your monthly consumption is printed on your bill. Your roof's usable, unshaded area can be assessed before anyone drives to your house. The subsidy timing is a fact of the scheme, knowable on day one. The approvals are the same approvals for everybody. None of this requires a site visit to establish approximately — and approximately, stated honestly, is worth more than a precise-looking number that moves later.

So the sequence that survives is: get the real number first, with the real conditions attached, before anyone asks for money. Then let one party own every form between you and a working system.

You can start that in under a minute — your bill, your roof, an honest estimate: helira.in/start.

What does the honest number look like?

Take a 3 kW DCR system on a Bengaluru independent house, base case — where the existing sanctioned load already covers the system and no increase is needed. The all-in cost is ₹2,62,725 including GST, and the net outlay after the ₹78,000 PM Surya Ghar subsidy is ₹1,84,725 — the full line-by-line breakdown, including where the sanctioned-load increase fits, is set out in our worked example.

This is an illustration, not a quote. Your own figure depends on your roof, your bill and your sanctioned load.

Two of those lines are the ones that usually go wrong elsewhere, so here they are in plain terms.

Regulatory handling — ₹15,000. One fee, one point of accountability: the PM Surya Ghar application (where you opt in), your society or RWA NOC, civil-work permissions (BBMP or BWSSB where applicable), the net-metering paperwork and the coordination with BESCOM. You sign the forms; we prepare them, file them, and follow up with the sub-divisions until they clear. It is a single line — never a pile of separately-named charges that grow after the site visit.

The sanctioned-load increase is not in that bundle. If your existing sanction is below the capacity your roof warrants, BESCOM requires an increase before net metering. That is a separate statutory line, billed extra, charged on the increase and rounded up to the next kW: ₹10,000 for +1 kW, ₹15,000 for +2 kW, and ₹7,000 per kW for +3 kW and above, each plus 18% GST. It is nil if your current sanction already suffices, and nil if you arrange it yourself. Shown upfront on the proposal — which is precisely the moment it should surprise you, rather than six weeks later.

And on the subsidy: for a 3 kW system it is ₹78,000, paid to your bank account after commissioning. Because the scheme requires DCR panels, which cost more than imported equivalents, the true incremental benefit is closer to ₹59,000 — an approximation, but a far more useful one to plan around than the headline.

Who answers the phone in year four?

This is the question that decides whether a 25-year asset was a good idea.

Helira Energy Private Limited is a brand and technology company for residential rooftop solar in Bengaluru. The physical installation is carried out by installers certified to Helira’s standard — but your contract is with Helira Energy Private Limited, and the warranty and accountability stay with us, not with whoever held the drill. One company answers for your system. You never chase a manufacturer or an installer between them. What is covered, and what is not: Warranted by Helira.

That is the whole difference between a registration and a running system: someone whose name is on the outcome.

The short version

Solar plans in Karnataka rarely fail because solar is a bad idea. They fail because the sanctioned load surfaced late, the price moved after the visit, the paperwork had no owner, the subsidy timing was misunderstood, or nobody would answer for the result. Every one of those is knowable at the start.
