We were very happy to go with SunPower by EmPower Solar and very pleased with the results. From start to finish, they are very knowledgeable and informative. They took us through the process from beginning to end. No surprises. Everyone involved were great. They listened to our concerns and helped us make the best decisions. I love the SunPower Monitor. I can see daily how our system is performing, which is great!! I would highly recommend them.
