Sesol Reviews 

never expect to get scam from a such big company,purhcased a batch of panels sold as 'new but repacked' i literally received garbage used and scratched panels ,ask for a partial refund and they just disappered not replying anymore to email or whatapp, i deal with a guy named Jonatahan don't trust them,don't buy if they say new repacked they are giving you the scrap left over.

Jag har haft ett återkommande problem med mitt solcellssystem installerat av Sesol. I över två veckor har systemet visat “Faulty Power Collector”-fel, och den smarta mätaren är offline – vilket innebär att el inte styrs korrekt till huset, batteriet eller nätet.

Jag har fört detaljerade loggar, följt alla korrekta omstartsprocedurer (inklusive fullständig nedstängning av växelriktare och batteri), och lämnat över tydlig dokumentation till Sesol. Jag har dessutom varit tålmodig och tydlig i min kommunikation.

Trots detta är problemet fortfarande olöst. Den 17 juni visar systemet fortfarande samma fel, mätaren är offline, batteriet laddas knappt, och energiflödet fungerar inte som det ska.

Jag är besviken på den bristande supporten från Sesol och kommer att uppdatera recensionen beroende på hur de agerar framöver.

Title: Unresolved issue with “Faulty Power Collector” despite detailed logs and proper restarts

I’ve had an ongoing issue with my solar system installed by Sesol. For over two weeks, the system has been giving a repeated “Faulty Power Collector” error, and the smart meter remains offline—causing major problems with power routing to my house, battery, and grid.

I have kept detailed logs, followed all correct restart procedures (including full shutdowns of the inverter and battery), and provided Sesol with complete documentation. I have also been patient and polite in all communication.

Despite this, the issue is still unresolved. As of June 17, the system still shows the same error, the meter is offline, the battery is barely charging, and energy flow is not functioning correctly.

I am disappointed with the lack of timely support from Sesol and will update this review depending on how they respond going forward.

Redigering 20 juni:
Vi fick återigen besked om att en elektriker skulle kontakta oss “snart”, men ingen har hört av sig – precis som vid ett tidigare löfte för över två veckor sedan. Vi väntar fortfarande, och systemet fungerar fortfarande inte. Väldigt besvikna över bristen på uppföljning och ansvar.

Edit 20 June:
We were told again that an electrician would contact us “soon,” but no one has called—just as with a previous promise made over two weeks ago. We’re still waiting, and the system is still not working. Extremely disappointed by the lack of follow-up

Redigering 24 juni:
Vi kontaktade Sesol per telefon under måndagen. De kunde fortfarande inte ge oss något besked om när en elektriker kommer att kontakta oss. Enligt support har vi nu rätt till kompensation eftersom felet pågått i mer än 12 dagar – men ingen information gavs om hur detta kommer att hanteras.

Vi har nu haft ett ständigt fel i systemet sedan den 13 juni, och det fungerar fortfarande inte. Flera löften har brutits, och vi har inte fått någon konkret tidplan för åtgärd.

Edit 24 June:
We contacted Sesol by phone on Monday. They still could not tell us when an electrician will get in touch. According to support, we are now entitled to compensation since the system has been down for over 12 days—but no details were given on how or when that will be handled.

We’ve had a continuous system fault since 13 June, and it still isn’t working. Several promises have been broken, and no timeline for resolution has been offered. Our patience is wearing thin.

Redigering 26 juni:
Vi har nu fått besked från Sesol att felet – som gjort vårt system obrukbart sedan 13 juni – inte förväntas åtgärdas förrän någon gång i september eller oktober, alltså om 12–16 veckor. Det finns fortfarande ingen bekräftelse på när vår garantianmälan godkändes, vilket gör det oklart när kompensationsperioden börjar räknas.

Vi har nu haft ett helt ur funktionellt system i över två veckor, utan tidplan, utan åtgärd, och med enbart vaga svar. Vi är djupt besvikna.

Edit 26 June:
We’ve now been told by Sesol that the fault—which has left our solar system completely offline since 13 June—may not be resolved until sometime in September or October, meaning a delay of 12–16 weeks. There is still no confirmation of when our warranty claim was officially approved, which makes it unclear when compensation is supposed to begin.

We’ve had a non-functioning system for over two weeks, with no schedule, no resolution, and only vague replies. We are extremely disappointed.

Uppdatering 23 augusti:
Elektriker från Sesol fixade en lös fysisk koppling mellan växelriktare och batteri. Systemet fungerar nu igen. Vi inväntar besked om utlovad kompensation.

Solar cells, batteries and charging boxes can be easily obtained due to this company. My best friend is living in Sweden and once I visited him, we had a warm conversation, he complained about lots of compelxities with the process of building his house. I found this company and we decided to work with them because we wanted to get energy from renewable resources, not those which have their expiration date. Solar cells and batteries sold by these guys are of high quality and the price for the installment wasn't biting. My friend was quite satisfied with the result, me too, so I am reviewing it.

So my last post got deleted and Sesol reported it, that just shows how unserious this company is. This is straight facts and I have proof and text messages from the boss telling me I need to wait to receive my last salary. September I left the company and now it’s February and haven’t received and notice regarding my last payment.

Reported that the equalizer stopped working beginning of Dec.
After 3 weeks I got a request for more info which I provided.
Then nothing.

I was about to sign a deal with another company when my neighbor recommended sesol. The price was the same, so I decided to hire them for the project. I signed the papers in the end of May, and they promised to deliver it around the end of June. So far I'm extremely disappointed. You can't trust their seller, not only they don't keep their timeline, but also the solution recommended by him was wrong. It was stressful to adapt to what the installation crew told me to do afterwards. The delivery was done early July, but installation took place a month later. During this month, the house owner is responsible to keep it safe and dry. The panels were mounted 6th of August and they produced 0 kWh of energy, because sesol can't find anyone to connect cables.

Since Skatteverket announced you can use subsidized battery for power grid balancing, I decided to use my battery with CheckWatt, but they require you to contact your installation company to sign with them. I've contacted sesol twice in this matter, and besides the usual reply from support ("we're sorry for late reply, we'll get back to you asap"), nothing else happened.

I'm planning to invest another 300k SEK next year into my solar installation, and I know it won't be with sesol!

The installation was really good, and the work was carried out professionally. However, there was a lot of missing information and miscommunication, and for example we did not manage to change our electricity provider and now we are producing electricity that is sent back to the grid and for which we do not receive money, as the Checkwatt system is not currently used by EOn yet. Also, it took forever from delivery to installation, and our grass was really suffering having all the equipment sitting there for 2 months. All in all, since SeSol is the highest in Sweden, I was hoping for a better service.

The installaton was very fast but the approval took some time as the process was messed up. Also some of the tiles on the side of the roof were not put back.. Overall it was a nice installation

Battery delivered, but not working.
After 2 months still no action from SeSol.

We finalized our project with Sesol, but unfortunately I can not reccommend this company.

Pros:
Good products (inverter & panels)
Good first impression when serting up the project.
They have their own people doing the installation (less contractors)

Cons:
Project planning is a disaster. We had many months of delays.
Low monetary compensation for delays.
Workers come unannounced, despite complaints.
Even their own workers have bad opinion about their own company.
Custommer service is a disaster.
If you have any smaller issues with the installation then you are on your own.

All in all the project was a success and the solar panels do what they are supposed to do, but if I had a second chance I would choose a different company.
