I am extremely Impressed with Celestial Solar. I called other Solar company's who came out to give us estimates. Celestial is the most professional company out there. Celestial was on time, the installers were wonderful. Other companies were unable to install in a timely manner (ie.. months) From the date of estimate from Celestial to install was only one week. Ben Nef is fantastic and a huge asset to this company. Communication is amazing. Celestial has a class act operation going on! We are very pleased.
