Advenso

Mijn ervaring met deze firma' Advenso, is top. Al van bij het eerste gesprek straalt Matthias met zijn professionele uitleg en zijn geduld voor leken zoals ik, vertrouwen uit. Meerdere offertes werden doorgestuurd, planning was top, de electricien, Stijn, is heel professioneel en eveneens de plaatsing van de zonnepanelen gebeurde zonder problemen. Door iedereen werd voldoende uitleg gegeven. De vragen na de plaatsing voor de app werden ook zonder problemen beantwoord en er is opvolging vanop afstand. Zeker een aanrader!. Bedankt aan de ganse ploeg. Hier een heel tevreden klant!

vriendelijk, geeft informatie,

"I was connected with Advenso through Groepsaankoop for Solar panels and batteries, not my own choice, but here is my honest feedback. I will share 4 major issues that we have encountered during installation of the solar panels and batteries. Long story short, avoid this organization if you want a transparant project.
1. They reduce the cost for installation on purpose, to make it look cheaper. Once you sign their Offerte, the send a person to validate installation. And then he makes you sign a document, which adds additional cost on top of the previous agreed price. Pay attention, this is a hidden cost they charge to people if you trust them. They might have more details, but they will not include it in the original price offer to make it look cheaper so you will sign the offer. That was the case with me. They knew that we already had some solar panels, but didn't include additional cost for ""aanpassing strings op de dak van bestaande installatie"". When that guy arrived, I was on the meeting, he inspected quickly the location where the batteries should be placed and then I had to sign a document. Without readying full document, I signed it, I though it was for his visit. Instead, apparently I agreed on additional of €415 on top of the offer. He did not inspect the flat roof and didn't check where the solar panels should be installed. Pricelist for the hidden costs is included in the picture.
2. When Advenso is cheking how many panels can be installed, they just use google maps satellite view. They randomly give you more panels than can physically fit. Because afterwards, they only reduce a small amount for not installed panels. I have received an offer for 9 panels €3221 (=+-€357/panel). Physically installateurs have installed only 8 panels. At first, I have received an invoice for 8 panels and (!)€30 less. After long discussion and including Groepsaankoop, they reduced the amount by another €180, so in total +-€210. However, if they had calculated and inspected the location properly, the invoices should have been €357 less.
3. They are not recognizing their own mistakes, until you escalate the issue. I had to involve Groepsaankoop to get some help. The first projectmanager Matthias stopped responding to me when I started asking the questions about the incorrect calculation on the invoice.
4. On the day of installation, they didn't had some parts that were required. All solar panels and battery were placed but not connected, including our old panels. It took 2 weeks to get it sorted. In fact, no injection for 2weeks in July, during the most sunny month.
They make it look cheap, but in the end, after recalculating all the hidden costs, they are not. That's their business model. Good luck!"
