We are very satisfied with the personal advice, processing and execution. All contact persons at Energieinsel, in particular our personal advisor Mr. Gloy, project group 3 and Ms. Küßner from the financing department were very committed and gave us the best advice.
The companies and trades involved also worked to our complete satisfaction.

The advice was precisely tailored to the project, adapted to our needs, everything can be done, nothing has to be done, we never had the feeling that we were getting a service that we didn't need, serious to the point.
They say what they do, they do what they say. For me, exactly what I expected.
Thank you

Competent and friendly advice right from the start, time was taken to answer all questions. Transparent planning with the relevant advance information, prompt and punctual execution of all trades involved. All planning and coordination services were provided by Energie-Insel, a pleasant all-round carefree package.
Not the cheapest provider, but due to the smooth process we would gladly use them again!

The work of a subcontractor caused a problem that led to delays in the commissioning of the entire system. However, Energieinsel worked out and implemented an amicable solution.
The cooperation with an installer for heat pumps worked very well, so that both systems were as if made of one piece. Highly recommended.

Recommendation
We were particularly satisfied with the quality of the work carried out, with the individual consideration given to our structural conditions and with the minimal amount of damage to our structural substance that was required for the installation of the PV system. We were less satisfied with the amount of time invested in the survey, planning, order confirmation and execution. Overall, however, it is clear that the result is good and good things take time.

The planning took a very long time, but the implementation with the installation of the system was very satisfactory. Due to frosty weather, the installation of the electrics was started on two days in January. A super team of three worked quickly, conscientiously, effectively, very thoroughly and visually excellently on the finishing work in the cellar and outside, including the charger up to the edge of the roof. As I said, January was cold and slippery, so in the 4th attempt a new team of 3 did the roof work again. It was simply crazy how the 16 parts were completely assembled from 8:00 to 12:30 at plus 1 degree. I can only recommend Sonneninsel for their craftsmanship and I would like to emphasize two people. Firstly, the salesman Thomas Wiebelitz and the electrician Kutte and then the others. We did not ask or were not told why the planning took exactly 1 year. Today, the whole family, from the 13-year-old great-grandson to the 93-year-old great-grandfather, look at the apps from Sonne and SolarEdge and marvel together at the results of our solar system from Sonneninsel. All German quality and with a long guarantee. We have become happy customers.

What is to be criticized is that there is no detailed billing. All items on the invoice are not listed in detail, but there is a lump sum total.

It took exactly one year from planning to implementation of my solar installation. The planning and implementation process went without a hitch. The employees were available at all times and helped with questions competently and quickly. The implementation (panels and electrical installation) took exactly two working days. Deadlines were met one hundred percent, the construction site was set up smoothly, as was the dismantling of the construction site. Everything was left meticulously clean. All the employees are extremely friendly. My expectations were fully met, if not exceeded.
Conclusion: It is better to spend three euros more, but to get good quality.
As a "bonus" I would like to add that the registration and commissioning of the system via my basic supplier was completed within 7 working days with the renewed assistance of Engergieinsel (Federal State of Brandenburg).
I don't think it could be better :-) big smiley

Very good coordination of the trades.
Agreed deadlines are met punctually.
Exceptionally polite, friendly and helpful German-speaking staff.
Inquiries are generally answered very quickly.
Very careful execution of the electrical installation and scaffolding erection and dismantling.
Quotation and invoicing were not very transparent (no individual prices).
The realization of the project took 15 months instead of the (non-binding) 10 months predicted when the order was placed.
The company's internal communication needs to be improved. On several occasions, information did not reach the employee responsible or involved.
Deadlines were sometimes communicated at very short notice (the day before).
