I've done business with Paul Soucy numerous times over the past year, he is always available to answer questions about the equipment from installers and residential customers. He even made a two hour+ drive to come train our installation crews in-person. Each SunMate panel comes with everything needed to install the system, down to every last screw and bottle of caulk. He's literally thought of everything!

They said that is what it cost to transfer the ownership of the solar panels from me to the buyers of my property. Absolutely ridiculous.

Recently, when seeking repairs I was able to get through to Invaleon's answering service, which referred me to Silvermane Solar, a company run by Sven Amirian, the same person who was on all my Invaleon paperwork 3 years before. The office manager at Silvermane told me that Sven started Silvermane after leaving Invaleon in 2018, but that timeline makes no sense since he was on my 2022 paperwork. Unless I get information to the contrary, I'm assuming they started Silvermane just so they can still (over)charge people for repairs while refusing to honor the warranty. Please use any other company but Invaleon.

System design was good - the owner is a technical expert - and installation was quick and professional. Output exceeded the guarantee by a small margin and still does. Service - Over the last 9 years there have been a few minor technical issues but these were electronics-related not installer issues. They've always responded to calls - sometimes it takes a few day but they've never ignored me - and the issue always gets addressed. No one is perfect and Invaleon is no exception but they supplied a good system at a fair price and have performed work to contract.....and been pleasant to deal with. As part of my day job, I deal with big industrial contractors and in comparison with many of them Invaleon has been a pleasure to deal with.
