Recommendation
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).

Everyone worked very carefully and the carport has become a real gem. The electricians "as a courtesy" also connected a lamp, which was very helpful.

Because the advice and execution were good to very good, except for appointments. But you have to pay a lot of money for that.

With the advice of H. Lehmann. The company that installed the system on the roof, the fitters were super and really worked hard in the full sun at over 30 degrees, special praise for this. Appointments were sometimes a bit bumpy, but we are very satisfied with the overall package.

We ordered a PV system with emergency power from SolarEdge from Energieinsel. The system with 10 KWP and a storage unit of 9.2 KW was not cheap. But with a 25-year guarantee on the entire system, including the inverter, it was certainly worth the price.

We were looked after by a very friendly and competent project consultant, from the initial consultation and quotation to the conclusion of the contract.

The installation of the solar panels was carried out separately from the installation of the electrical components in the house. On both dates, the work was done very neatly. The installers were competent and answered every question expertly. Communication with the entire Energieinsel team was always friendly and quick responses are obviously part of the team's everyday routine. The system was commissioned just one week after installation. Since then, we have been marveling at the performance of our system via the convenient app, which gets an amazing amount out of the light even in cloudy weather.

The result is impressive in every respect and exceeds our expectations. The Energieinsel team did not disappoint us.

The only suggestion for improvement we gave the team is that we would like the quotation and invoicing to be more transparent. Everything else was great.

We are completely satisfied and can only warmly recommend "Energieinsel". We would particularly like to emphasize that Ms. Franziska Hornig, as customer advisor, is always available from the first contact throughout the entire construction period and has an open ear for all questions.

In principle, the energy island is customer-oriented, but it took just under a year from commissioning to installation and the installation was very bumpy due to a lack of trained personnel and took longer than estimated. However, the end result was fine.
