What We Can Help With
- Data corrections: our calculators run on city-level peak sun hours, DISCOM planning tariffs, subsidy slabs and 2026 per-kW price bands. If you spot a figure that has gone stale, for example a revised tariff order or an updated subsidy rule for your state, tell us the city or state and include a link to the official source. Verified corrections go straight into the calculation engine that powers every tool on this site.
- Tool suggestions: missing a calculator you needed? Describe what inputs you have and what answer you were looking for, and we will consider it for the roadmap.
- Bug reports: if a calculator gives an output that looks wrong, send the exact inputs you used (city, bill amount, system size and so on) so we can reproduce it.
- Advertising and partnerships: the site serves ads through Google AdSense. For direct advertising or partnership queries, use the same email with "Advertising" in the subject line.
- Content use: want to reference our tables or estimates in an article or report? You may, with a link back to the tool page you used.
What We Cannot Help With
We are an independent estimates website, so please note:
- We do not sell, install or quote solar systems, and we cannot recommend specific installers or brands.
- We are not affiliated with any government body, DISCOM or subsidy portal, and we cannot check, file or speed up a subsidy application. For subsidy applications, contact your DISCOM or the official national rooftop solar portal.
- We cannot provide personalised financial advice. Our EMI calculator and savings calculator are planning tools, not loan or investment offers.
Anything you email us is used only to reply to you, as described in our privacy policy.
