Our system has been installed and operating for a little more than a year now, our system has produced more the expected bringing our yearly electricity bill to zero. While researching solar PV systems I had received several quotes from five solar providers, after asking several questions and numerous emails back and forth I was confident to go with Mike and his team at Watts Up Solar. They were always willing to answer any question I had no matter the time of day and explain everything in detail. A year into the system, there have been no problems.They have knowledgeable staff, great workmanship, kept a very clean job site, great products and truly know the equipment. After a year into having our solar PV system installed operating, if you are considering a solar installation I would highly recommend Watts Up Solar!
