How it works

From your electricity bill to a running solar system — in three steps.

01

Run the calculator

Tell us your bill, roof, and hours lost to power cuts. An honest estimate in 60 seconds — including whether solar actually makes sense for your home.

02

We assess your roof

Our own expert does the site visit and produces an independent report — sized for your home, not for a sales target. Theirs to sell. Yours to keep.

03

Compare quotes that are actually comparable

MNRE-certified installers quote against the same WM report. No site-visit upsells, no oversized systems, no cold calls. Pick the installer that fits — we'll guide you.

The independent assessment

₹99 that saves you a ₹4 lakh mistake.

A free installer visit isn't really free — the person measuring your roof is the person who profits from selling you the biggest system. For a refundable ₹99 you get an assessment by someone with nothing to sell you.

No installer agenda

Our assessor isn't trying to sell you the biggest system. We measure what your roof can actually carry and what your home actually needs.

Refundable if you install with us

Free if you convert, paid only if you walk away. The ₹99 is a refundable commitment token — not the price of a visit. The independence is the point, not the fee.

The report is yours to keep

Sized BOM, savings projection, subsidy eligibility, structural notes. Take it to any installer — or take it to ours, where every quote is built on the same baseline.

We never sell your number

Your contact is masked from installers until you choose to engage. No cold calls. No follow-up spam from vendors you never picked. Watt Matters is the only party that talks to you.

The ₹99 assessment kicks in only after you decide to move forward.

How we're different

Side-by-side quotes

Apples-to-apples,
for once.

Every installer quotes against the same independent WM assessment. Same kW. Same BOM baseline. So when prices diverge, you know exactly why — and you can pick on fit, not on whose visit was the most convincing.

MNRE-certified installers only

Every installer is government-registered and has completed at least 100 installs in their region. We've done the vetting so you don't have to.

100+ verified across India

We tell you when solar isn't right

Rented home, shaded roof, bill under ₹1,500? We'll say so. Nothing builds trust faster than an advisor who puts your interests first.

We stay after install

Your project, on record. For life.

Project repository (design, invoices, warranty, net-metering papers), maintenance reminders, complaint mediation, and a service backup if your installer ever steps away. Most marketplaces ghost after the sale. We don't.

Free site visit vs independent assessment

A free installer visit is a sales call. You don't pay in rupees — you pay in bias.

Watt Matters assessment

Whoever measures your roof also wants to sell you the biggest system

Independent assessor — paid by you, not by an installer's commission

Each installer brings their own sizing assumptions — comparing quotes is impossible

One shared assessment. Quotes diverge on price + warranty, not on system size

Free visit feels free — until you're stuck with an oversized 6 kW you didn't need

Right-sized for your roof, your bill, your power cuts. Refundable when you install via us

Your phone number is sold to 3 vendors who call for months

Contact stays masked until you choose. We never sell your number — full stop

When the installer ghosts post-sale, you're on your own with warranty + maintenance

Project repository, complaint mediation, maintenance reminders, service backup for life
