Embed Our Calculators on Your Website

Every ProSolarCalc tool is available as a free embeddable widget — the live calculator, styled and kept up to date by us, running inside a simple iframe on your site. Perfect for solar installers, bloggers, energy sites and forums. No API keys, no signup, no cost. The only condition: keep the attribution link below the widget — that link is the license.

How it works

  1. Pick a calculator below and click Copy embed code (or use the embed box on any calculator page).
  2. Paste it into your page’s HTML. The widget loads the calculator in a clean, chrome-free view with a small ‘Powered by ProSolarCalc’ bar.
  3. Keep the attribution link under the iframe. The included script auto-sizes the frame height as users interact (optional but recommended).
Terms, in one sentence: free for any website, commercial or not; do not remove the attribution link or the powered-by bar, and do not present the tool as your own. Widgets always compute from our latest published data — when we update a subsidy or tariff, your embed updates too.
