Super advice from ZOLAR
-We were very well advised by our contact person, Mr. Rick Kengen. He responded to all our wishes and was available at all times. So far, one of the best consultations regarding PV systems.

I was very satisfied. The advice at the beginning, the customer service during the implementation, even with adjustments due to the supply bottlenecks at the moment, the timing and the partner company Solaray on site were excellent. I would do it again with Zolar in a heartbeat.'
Many thanks

We received really good advice from Mr. Nicolei, but then decided to go with another provider because they evaluated the average hours of sunshine over the last ten years in comparison to sunny regions (Freiburg Breisgau / Munich). Furthermore, we were offered a solution by means of amplifiers, but unfortunately Zolar did not come up with this idea.

Dear customer,
thank you very much for your positive review.
We are pleased that you were satisfied with our advice.
At zolar, we examine the location and conditions of our customers' solar projects very carefully in order to provide needs-based and economical advice. The reason why we did not recommend module optimizers in your case is that we could not see any partial shading on your images of the roof as well as the satellite images.
Even if we will not realize your solar project together, we wish you much pleasure in producing and using your own solar power.

Recommendation
I was interested in a PV system with battery storage in December 2020.
When I searched for offers, there were some more expensive offers and also local providers who had no capacities.
The first contact with Zolar was very positive and the online configurator is really good.
However, as always in life, it is advisable to know yourself what you want and need.
There was an on-site visit about the feasibility of the project.
The further communication runs exclusively by email or with agreed telephone appointments which were always kept. This takes some getting used to, but it worked.

The work was all done well according to my personal assessment. The employees were nice and willing to talk. There were actually no major delays.

One module had a scratch after completion of the work, which was not communicated. I was not on site at that time. I do not want to imply that this was not communicated intentionally. But it was not so good for the time being. I have complained about it with photos. It took some time with the reorder and installation of the new module. But Zolar has proven that they act correctly and seriously.

The installation of the bidirectional meter took almost two months, but Zolar can't be held responsible for that.

The plant does not reach its planned 10.8 kwPeak but the modules are distributed on 3 directions east / south / west maximum I had probably 8, ... kWPeak.
But the 10,8 kwPeak is the ideal value. You should be aware of that.

I have also ordered a 12 kwh battery and I am glad about it. It can be deducted from the input tax and helps to charge the electric car when the sun is not shining at its maximum and in the evening when electricity is also consumed and, for example, the heat pump is running.
The wallbox has also installed Zolar in connection with the PV system.

I can recommend Zolar, because everything has worked and have always responded seriously.
Smaller things there certainly can be improved and of course you have to keep in mind that you are not the only customer and therefore some things do not go as quickly as you would like. For me, 4 months in total + 2 months. Waiting for the meter to be connected by the network operator.

PS: All formalities with network operator and federal network agency has also taken over Zolar. 👍

Thanks again to Zolar. I am satisfied.

Hello, was fully informed and advised by the consultant Mr. Orestis Anastasiadis. My specific wishes were addressed and an appropriate offer was made. After the first phone call, I was given access to the online configurator, which is really good and transparent. I found it particularly good that I was not pressured to conclude at any time. I can only recommend ZOLAR GmbH. Unfortunately, it did not come to the conclusion of the contract, because internal family problems stood in the way of the conclusion. If a solar plant, then ZOLAR GmbH! Thank you very much!

Quotation was made by a very nice and competent customer consultant. Offer, according to my ideas, was created in a very short time on the Internet. Since I have decided otherwise, however, I can not make any statements about quality and performance.

Poor
Unfortunately, very bad experience. Offer phase was still good, then a disaster. Before ordering, an implementation period of 8-10 weeks was promised, then nothing happened. No information - nothing at all. Inquiries were not answered and only referred to the fact that one should have patience. After 8 weeks, the first viewing appointment should take place. Unfortunately, the staff is not customer-oriented at all. Order was then canceled - after 20 days is still no refund of the 500 € deposit. Are all the good reviews here just fakes?

Dear Customer,

First of all, we would like to formally apologize for the delayed refund of your deposit in the amount of 500€. Unfortunately, the transfer in your individual case could only be released late, but has now been made and will be received in your account in the coming days.

This delay is in no way in line with zolar's style. We therefore hope that you will accept our apology.

With sunny greetings,

The planning is complete and on 28, 29, 30.8 will be installed 8 Kwp plant. Quality I have not yet evaluated, because the plant is not yet installed. But will still give an overall assessment at the end. So far I am but very satisfied especially with the advice of Mr. Rene Böth, the absolute blast, just mega good!!!!! For one it is a vocation and for the other simply a job. Callbacks were mostly immediate or on the same day. I have looked closely at the reviews here and join Mr. Müller. An acceptance protocol is very important to me see. I also informed Mrs. Vocke in an email (customer service). Here still fast the evaluation of Mr. Mueller. I think the solar team still gets that done.

The advice and planning and installation all top, only then it became extremely tough and unpleasant. Despite multiple requests and countless mails and inquiries, they do not see themselves in a position to create an acceptance protocol of the system and hand it over to me with the measured values of the system. One considers corresponding commissioning measurements of the VDE as a mere recommendation and not as the standard of action. Obviously, the realization during installation "oh it all works" is sufficient as commissioning u as proof of a Sach- und Fachgerrrchten assembly. So caution to all, because should it come to a technical defect with fire consequence, the air becomes quite fast thin. This is exactly how it is with the proofs of the modules. These flash certificates are the only proof of the modules' performance when new. Here, too, one had to literally beg to be moved in order to provide these proofs. Without such evidence, no real guarantee of guaranteed performance towards the end of the warranty period! Cable feed through the underlay not with the intended sleeves but tape and glued. So in conclusion remains to say installation ok u cleanly executed but Adminstrationstechnisch a disaster

Recommendation
The consultation, offers and initial planning (sales) went well and with commitment. After the contract was signed, the handover to the project team also worked well. In the subsequent implementation of the project, there were unfortunately a few weaknesses, in particular a project planning was not to be recognized from my point of view. The communication to the "subcontractor" who installed on site did not work so well from my point of view, so that I had to ask several times myself. In the actual realization is still unclear to me who has planned this final (Zolar or the installing company) at least no coordination has taken place here. I would also have liked to see an acceptance protocol according to VDE or similar, which can also be useful for insurance reasons.
Certainly, every situation is somewhat individual.
My conclusion: Before signing the contract, define a rough time period (e.g. month) of the complete installation, as well as clarify the desired documentation and acceptance protocol beforehand.
System including battery storage runs well, I am satisfied with the components.
The customer service seems to work well, can basically recommend Zolar.

Advice and execution were excellent. The system was installed quickly and easily despite pouring rain. Craftsmen worked cleanly and quickly. The support on site and by the ZOLAR staff in Berlin went hand in hand, so there were never any delays or misunderstandings. The documents provided were complete.
