Everyone we had contact with from sales to installation were extremely friendly and helpful. Due to issue with our existing roof we had to postpone the installation 1yr and Sunation honored the original quote, no questions asked. Due to Covid-19 supply shortages they had to substitute panels to a different manufacturer which required additional panels which they provided at no extra charge, increasing my total output an extra 400 watts. Sunation handled all the paperwork and made for a smooth and speedy process from start to finish. 100% satisfied.

Christina, over 1 month

We were told that we would get the system installed by 2020 and receive the 2020 credit. Fast forward to March, still waiting for installation. After we paid the deposit in September, pretty much radio silent through February. We would have gone with a different company who told us they would write off the difference if not installed in time, now we have to eat the cost. Unless you get the promised work/timeline in writing, otherwise do not make any payment.
