JAMP GmbH Photovoltaik und Stromspeicher Wuppertal

My mother-in-law took the plunge and commissioned a photovoltaic system. Mr. Borys from JAMP GmbH explained everything very clearly and empathetically, so my mother-in-law felt well taken care of. A 9.9 kWp system was installed on two sides of the roof. A 16 kWh battery storage system is now installed in the basement. In the event of a power outage, the house has three-phase backup power. The system is fully controlled by artificial intelligence. The system was ordered on June 18, 2025, installed on the roof on July 17, 2025, and the storage system was installed on July 18, 2025. Everything

After receiving excellent advice from Mr. Borys, we decided to have a photovoltaic system, including storage, installed by Jamp GmbH. The entire process was fantastic, and the installation was flawless. We've since had a wallbox from Sigenergy and a solar expansion module installed by the same company and are very satisfied. Mr. Borys answered all our questions very informatively and always had great tips for us beginners. I can highly recommend Mr. Borys, the owner of Jamp GmbH.

Very friendly and competent advice, as well as uncomplicated contact with prompt assistance. A truly exemplary company, both in its organization and in its expertise, with friendly, approachable staff on-site. We were very satisfied with Mr. Senad D.

The consultation was excellent! However, it would be appropriate to clearly state that the actual work would be carried out by a different company, which also did a very good job. Communication with the contractor could be improved during the preparation phase. Overall, very solid work that I would gladly recommend.

JAMP addressed my request very quickly. I consider the company to be extremely reputable. Of course, JAMP wants to make money through its work. However, that doesn't seem to be their primary focus. I am convinced that the owners and employees of JAMP are primarily concerned with satisfying their customers through good work.
