I have used Diablo Solar Services for various repairs for my solar system. For this job, they repaired and replaced the sun power controller box or main power panel. They really struggled to get a replacement box due to a change in the industry but they went to bat for me and found the correct one. It did take some time, about a month and was really challenging to find it but they persevered. Once they located the power box they were able to install it quickly and took great care not to damage my roof, which is different than most avoiding the cracks and things. Since this repair, I have had no issues at all!
