I arranged the photovoltaic installation from abroad. When I arrived on site, the deadlines were met, and the work could begin on the scheduled day. The technicians were absolutely professional. The installation was up and running in three days. I highly recommend Solstis!
From the request to the commissioning, everything went very well! A team of efficient and attentive professionals. The few minor issues encountered were resolved quickly and to our complete satisfaction. Furthermore, Solstis's quote was among the least expensive of the ten offers received, while offering a more attractive product. I highly recommend Solstis!
Great work, fast, good coordination, just a shame the electrician didn't protect the parquet floor when using the jackhammer... Otherwise perfect 👍 R&I Grobe
The company tried generated a quote with some work that I said was already done, thus increasing the quote by 1k+ & thus billing me for the work I have already done. They were unable to generate a quote taking into account the work that was already done. This is unacceptable. 4kCHF for drawing a cable, connecting it on 2 ends and generating a certificate. I do not recommend.
My solar project with Solstis went perfectly, from the initial visit to define the needs to the completion of the installation. The deadlines were met. Everyone involved was efficient, professional, and caring. I am very satisfied with my choice of Solstis and can only recommend them.
