I highly recommend Sunpro. My sales rep was extremely knowledgeable and patient. I seriously compared apples to apples for months before deciding to use Sunpro, and he was instrumental in making me comfortable (thank you. Lawrence!} I have had the panels for 5 years now and am very happy with the installation and production. I have a zero dollar monthly bill. and at the end of the year when the electric company audits production. I usually get a credit of around $100. Now we are selling our house and Sunpro's customer service is helping to facilitate the transfer of the lease to the new buyers. I am very pleased with Sunpro on all levels.
