1825 solar installers registered and practising across 67 towns in Alicante province, taken from the Registro Integrado Industrial, Ministerio de Industria y Turismo (datos abiertos, estado a 31/08/2023) on 8 October 2026.
Self consumption, with or without a battery. On a house used four months a year the sums are completely different from a house lived in all year, and honest installers say so.
Every name on this page is an installer registered with the Generalitat for low-voltage work including generating installations, which is what a solar array is, as published in the Ministry's Registro Integrado Industrial. Registration is what the law requires to sign off this kind of work; it is not a review of the firm. Each listing shows the registration number and every category the firm holds, exactly as the register states them.
Pick your town
Only towns with at least two listings appear. A town page with a single line is not a page, and filling a site with near empty pages damages the ones that are useful.

The Ministry's open-data file is dated 31 August 2023 and carries no address, so we show the town only; a firm registered since then is not here yet. The file lists sole traders as well as companies: we keep the name and the town, never the tax number.
