<br>
I’ve inherited an incorrectly sized solar thermal evacuated tube system. <br>
It’s too many tubes for the use most of the year. <br>
<br>
Does anyone know of a design or product that can remotely cover them?  <br>
I can find shade cloth of course that I can cover them but something remote control would be better <br>
<br>
Thx<br>
Jay<br>
