The calculators run in your browser. The numbers you enter (bill, tariff, location) are not sent to us, stored, or sold. If you use "search my location" or geolocation, your query/coordinates are sent to third-party data providers (OpenStreetMap for place lookup, NASA POWER and Open-Meteo for data) solely to return results — we don't retain them.
If advertising (e.g. Google AdSense) or analytics (e.g. Google Analytics) are active, those services may set cookies. You can opt out of personalised ads at Google Ads Settings and manage cookies in your browser.
arasniff provides free estimates and information for planning only. By using the site you accept that all outputs are estimates, not professional, financial, or engineering advice, and not a price quote. You are responsible for verifying figures (subsidies, tariffs, prices, rules) before making decisions. The site is provided "as is" without warranties; we aren't liable for decisions made based on it.
Estimates depend on stated assumptions and third-party data (NASA POWER, Open-Meteo, OpenStreetMap) which can change or be unavailable. Local factors (shading, roof, sanctioned load, exact tariff slabs, current government rules) materially affect real outcomes. Always get professional quotes and confirm current subsidy rates through official channels before purchasing.
