HOW IT CALCULATES

Solar Panel Calculator — calculation method

Enter average monthly use and roof area — the calculator picks the panel count and inverter, then shows yearly output and payback time. For installers, SiteHub builds such a calculator into your website with your own prices and equipment.

  • Required power = yearly use × coverage ÷ specific yield (kWh/kWp).
  • Output is adjusted for orientation (south, east-west) and roof pitch.
  • Panel count is capped by the real roof area, including service gaps.

Demo prices are illustrative and configured for your company. SiteHub builds calculators like this for websites.

How accurate is it?

It is an initial estimate based on the assumptions shown on the page. The final design follows a site visit and real roof data.

Can I put this calculator on my company website?

Yes. We adapt it to your equipment, prices and region, and requests arrive in your CRM or Telegram.

HOW IT IS BUILT

Not pictures — a calculation engine

Separate pricing engine

Geometry, formulas, constraints, catalogue and prices are separated and unit-tested. Money is computed in whole bani — no rounding drift.

3D from the same data

The wardrobe model is built from the parts list the price is computed from. Change the width and both model and estimate change.

Integration with your site

Requests to CRM or Telegram, products to OpenCart or WooCommerce, prices from the admin. No React, no heavy dependencies.

FAQ

Frequently asked questions

Are the demo prices your prices?

No. SiteHub builds software and does not sell roofing, furniture or glass. Demo prices, norms and materials are configurable demo values; in your project they come from your catalogue and price list.

Can I change prices and rules without a developer?

Yes. Materials, prices and norms live in a separate configuration that we connect to your admin panel in the project.

Does it work with OpenCart or WooCommerce?

Yes. The configurator passes the product with chosen options and the final price is recalculated on the shop server.

Must a visitor leave a phone number to see the result?

No. The result and estimate are visible immediately. A request is a separate, voluntary step and the configuration is attached automatically.

Does the 3D work on phones?

Yes, on WebGL-capable devices. The scene loads only when a demo opens, renders on demand and frees memory on close. Without WebGL the calculation stays available.
