I went with Diablo Solar Services to install a solar system on my roof. The installation was successful and people were pretty nice, but afterwards I found out the panels were susceptible to be hitting with golf $@!#%. After being hit, I tried to get a hold of someone from Diablo to talk to with no success. So for a while now, I haven't gotten anyone from Diablo to return my calls. I went with them for solar because they did a pretty good installation of a pool heater for me a while ago. However, communicating with them for a followup has been very difficult and frustrating.
