We just got about 500 sq/ft of Techno-Solis solar panels installed in the backyard with a Hayward Aqua Solar controller and it works well, actually sometimes too well. Pool water early this week was close to 90. Which made me wonder, in the peak of the summer, if the water was to be too warm, can the water circulation in the panel be turned off during the day... but then could the panels get damaged with the overheating? I can't really find information on the subject, I understand though that I can cool the pool with the system (circulate water at night to radiate out through panels) which would be one option if they can't be turned off. Thanks for sharing your experience.
