The deal between us, in plain English.

These terms govern your use of wattmatters.co.in and the Watt Matters service, operated by Deepam Enterprises (“Watt Matters”, “we”, “us”). By using the site, creating an account, or paying for an assessment, you agree to them. If anything here is unclear, email [email protected] before you proceed — we’d rather explain than surprise you.

What Watt Matters is (and isn’t)

Watt Matters is an independent solar advisory service. We help owners of independent houses in India decide whether rooftop solar and battery backup make sense for their home, size the system honestly, and — if they choose — connect them with vetted installers who quote against our assessment.

• We are not an installer. We do not sell, supply, or install solar equipment.
• We are not a lead-selling marketplace. Your contact details are never sold, and stay masked from installers until you choose to engage one.
• Your installation contract is with the installer, not with us. We vet installers, standardise their quotes, and keep your project records — but the supply and installation agreement, including its warranties, is between you and the installer you select. If something goes wrong we will help you raise it with them and put the paperwork in your hands; we cannot enforce an installer’s warranty on your behalf.

Estimates are estimates

Calculator results, assessment reports, savings projections, payback periods, and subsidy figures are good-faith estimates based on the information you give us plus public data (solar irradiance, DISCOM tariffs, the PM Surya Ghar subsidy rules as published). They are not guarantees. Actual generation, savings, and subsidy amounts depend on your roof, your usage, tariff changes, equipment, weather, and government decisions we don’t control. Subsidy approval and disbursement is entirely the government’s decision.

The ₹99 assessment

The ₹99 fee, paid when you book, buys a professional site assessment by a Watt Matters assessor and the resulting report — which is yours to keep, whichever installer you choose (or none). The price is all-inclusive: GST and payment processing are built in, and nothing is added at checkout. It is a fee for a real service, not a deposit toward equipment, and it is not refundable once the booking is made — except in the specific situations set out in our Refund & Cancellation Policy. If plans change, you can ask from your dashboard to move the visit — the first reschedule is free.

Accounts

• You must be 18 or older and provide accurate information.
• You’re responsible for keeping your sign-in credentials safe; anything done from your account is treated as done by you.
• One account per person. We may suspend accounts used fraudulently, abusively, or to scrape or resell our data.

For installers

• Installer partnership is by application and vetting; we may accept or decline at our discretion, and remove installers who fall below our standards.
• The subscription is ₹999 per month (exclusive of GST), billed monthly in advance via Razorpay and renewing automatically until cancelled. Cancellation and refund rules are in the Refund & Cancellation Policy. Cancelling stops new customer connections; it does not end your installer agreement or cancel fees on work already in hand. A completion fee stays payable on any quote a customer accepted before you cancelled — and on any quote you submitted before cancelling that a customer accepts within its thirty-day validity afterwards — however long the installation takes.
• A completion fee is charged once per job, as a flat amount for each kW — not a percentage of the project value, and it does not vary with what you quoted. It is earned when the customer accepts your quote, and invoiced at the earlier of commissioning or thirty days after acceptance — the thirty days being slack for net metering, materials and the customer’s own payment schedule, not an expectation that a job takes a month. Nothing is payable on a quote, on being shortlisted, or on a project cancelled before installation begins; where a cancelled project has already been invoiced, we issue a credit note. A project that is merely delayed is still chargeable. The rate is the same for every installer on the platform and is stated in figures in the installer agreement issued with your offer, before you sign. Government subsidy is not part of the calculation. GST is charged on the fee, and the fee is commission for the purposes of s.194H, so tax deducted at source is yours to deduct and deposit against a certificate.
• These two are the only charges. There is no per-lead fee, no per-quote fee, no placement fee, and no charge for a job you do not win.
• Customer contact details shared with you may only be used to serve that customer’s Watt Matters enquiry — never for unrelated marketing, resale, or off-platform solicitation of Watt Matters customers. Breach means removal from the platform.

Payments

Payments are processed by Razorpay, a licensed payment aggregator. We never see or store your card, UPI, or banking credentials. Prices shown are in Indian Rupees and include applicable taxes unless stated otherwise. If a payment is charged but the service isn’t delivered (for example, a duplicate charge), we refund it — see the Refund & Cancellation Policy.

Your data

How we collect, use and protect your personal data is set out in our Privacy Policy, which forms part of these terms. In short: we never sell your details; installers see only your area until you accept a quote; and the people and providers who handle your data for us — including our assessors and advisors, and Google, whose maps we use to locate and trace your roof during an assessment — do so only to deliver the service.

Our content

The site, calculator, reports, articles, and brand are ours (or licensed to us). You may use reports and results for your own home’s decision-making, and share them with family or your installer. You may not scrape the site, republish our content commercially, or use our data to build a competing service.

Limitation of liability

We stand behind the honesty and care of our advice, but to the extent permitted by Indian law: we are not liable for the acts or omissions of installers (your contract is with them), for government subsidy decisions, for losses caused by inaccurate information you provided, or for indirect or consequential losses. Our total liability to you for any claim is capped at the amount you paid Watt Matters in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited under Indian law, including for fraud.

Disputes and governing law

These terms are governed by the laws of India. If something goes wrong, email us first — almost everything is fixable in a conversation. Failing that, disputes are subject to the exclusive jurisdiction of the courts at New Delhi, India.

Changes to these terms

If we make a material change, we’ll email everyone with an account at least 14 days before it takes effect. Trivial edits (typos, clarifications) we update in place with a new “last updated” date. A change never applies to an assessment you have already paid for, or to a quote already accepted — those stay on the terms in force when you paid or accepted.
