Fearful
Participant[quote=jeeman]Well, I got a quote from Performance Solar to install 10 Sunstar panels including the computerized valve for $6970. Does this sound reasonable to all you folks?[/quote]
WOW
How much natural gas can you buy with $7 grand?
How much electricity is going to be used pumping the water up to your rooftop?
How long will the things last?
Plus they’re ugly as stink.
Side note, why don’t they make those damn things any other color than black? You could make, say, a terra cotta colored panel, and it would have a good percentage the absorbance of black. This is what happens when engineers make things like solar collectors. “Let’s make it black, because that absorbs the most light, 90% versus merely 80%!”
In solar panels, you can have any color you want, as long as it’s black.

Participant[quote=jeeman]Open loop…you mean, run the pipes out in the open sun?[/quote]
Open loop. Where you run the pool water up in the panel and dump it right into the pool.
I wouldn’t tie it to your domestic water because they are 2very different problems
Pool :water 58 f raised to 75. 17000 gallons, sterility not a big deal, seasonal,
Hot water 58 raised to 125 or higher, 120-500 gallons, sterility big deal, year round
So open loop is more efficient for small temp rise.
