I had an excellent experience with Sunshine Solar Technologies when they did the solar heating for my pool. They were very professional in explaining exactly what I would need, where they could put the solar heating panels, and how the system would operate. Everything turned out great.
After the winter of the first year, when I had some trouble with leaks, I called Sunshine Solar Technologies and they came out immediately. They changed the panels and told me how I could winterize them. Every step of way, they were there...and very helpful. I have not had any problems since then, and have been with them for 3 or 4 years now.
The solar panels are so much more efficient than having a propane tank heat my pool. I just have one expense, for the solar panels on the roof that they attached to a pump in my pool. My pool is toasty warm. I would definitely recommend Sunshine Solar.
