Istallati 4 kw di pannelli fotovoltaici Sunpower pannelli da 400 w. La resa è ottima per la posizione dei miei pannelli, producono circa 3800 w. Purtroppo non sono orientati perfettamente a sud. Mi riservo di aggiornare questa recensione nel periodo estivo così da avere il tempo di verificare i rendimenti con il sole allo zenit. Io per ora mi stoi trovando bene.

Warren was great, fixed a problem left behind someone who was fired from the company. Could have given up and left but stayed to fix a complex problem. For Warren specifically, this review is for him

I just recently moved into a new home and was having trouble activating my solar control box. SunPower sent out a tech, Warren, to help get it activated. Warren kept me informed via phone call for when he would be arrive and he got right to work. He was professional and explained everything to me once he finished the job so I understood how my solar worked. I appreciated how quickly he worked and how friendly he was! :)

Warren Grennan arrived on time on the day we had the service scheduled. He was very knowledgeable and walked us through using the system after installation. He was friendly and professional and set up the system very quickly for us.

Julian Sierra came out after I was unable to activate my system. He was extremely knowledgeable, professional and kind. My issue was quite troublesome but he stayed until my issue was resolved. I commend him on this, especially in a new development with prebuilt technology sources. He was very patient with me as I’m not familiar with how this all works. Even my internet was tricky because I initially went with one provider and upon activation of the smart home, my Wi-Fi was changed. It was very confusing to me, but he helped me sort through it all. Also, he took the time after resolving a lengthy activation process and walked me through the system to ensure I understood its functionality. Julian is a pure gem and an exceptional professional.
