Capner Bewertungen 

On 28th April I signed a contract for 39 panels and a battery. Included in the quote was a Dulaan 180 Thermodynamic boiler.
Despite many attempts from me and the chief of the "Service Technique Communal" to get a proper installation plan from Capner they only gave the proper information at the end of November and we were given authorisation from the commune on 5th December. on 17th December I received an email from the accounts department saying the onduleur and battery installation was planned for 7th and 8th January 2026 and enclosed an invoice for another large portion of the total bill 15554,99 € which I paid immediately.
Eventually some people arrived to install the panels, I think it was 28th February only to be told that due to technical reasons they could only install 35 panels instead of 39. I said no problem.
on 4th May I received an email from the accounts department saying that everything was now connected and enclosed the final invoice for the remaining 1728,33 €
The next day, on 5th May I replied that in fact I was missing 4 panels (at 612.85 each) therefore they owed me 723,07 and provided my bank details.
NO RESPONSE. And they have not given me the paperwork required to claim my money back from the government. Just gone silent.

⚠️ Avis important pour les futurs clients ⚠️

Je partage ici mon expérience avec Capner, afin d'informer les personnes qui envisagent de faire appel à cette entreprise.

En septembre 2025, j'ai signé un contrat et réglé intégralement l'installation de 15 panneaux solaires avec batterie. Le 9 décembre 2025, le technicien n'a installé que 10 panneaux — soit 5 de moins que ce qui avait été payé — et sans la batterie. J'ai donc payé pour 15 panneaux et n'en ai reçu que 10.

À ce jour, le 24 juin 2026, ni les 5 panneaux manquants ni la batterie n'ont été livrés ou installés.

Neuf mois après le paiement et six mois après l'installation partielle, la situation n'est toujours pas réglée. Les tentatives de contact avec l'entreprise sont très difficiles, et la seule réponse obtenue est systématiquement : « ce sera réglé dans 10 jours » — promesse qui n'est jamais tenue.

J'avais initialement recommandé Capner à trois autres foyers. Aujourd'hui, je ne le ferais en aucun cas. Je conseille vivement aux futurs acheteurs de faire preuve de la plus grande prudence avant de s'engager.

We have not had a good experience with Capner. All went well with the installation of the solar panels but the installation of the electrical components in order to connect us to the grid has been disastrous. There have been many changes of staff and we feel that the electricians who were sent at the beginning were not Capner employees nor very competent. It has taken months to get connected. We cannot recommend this company.
