Questions

Where do the prices come from?

Energy prices are read every day from each supplier's published price list and checked against it before they go live. Solar prices are the packages installers publish on their own websites; the solar estimates use PVGIS data for each county.

How are results ranked?

Energy tariffs by estimated cost for the household, solar packages by estimated payback. A commercial agreement never changes the order.

Is it free?

Yes: the website, the API and the MCP tools are free and need no account or key.

Which AI assistants can use Alva?
