Re: [RE-wrenches] Solar over a Pool

[Starlight Solar Power Systems]

85°….I wish…it’s 114° here right now. Unshaded pools are unusable for many 
summer months, even at night, without a refrigeration system. But, in the 
winter, they need solar gain to reduce heating bills. Not a good plan for a 
permanent cover.

Tom,

Down here a little further south in Florida, many of our clients might actually 
find that to be a benefit in the summer! Pools get bathwater hot here and 
nocturnal solar cooling is a hopeless proposition when it's 85F ambient and 95% 
humidity at night.

That said - I totally agree. Bad idea.

[toddcory]

increased corrosion from chlorine gas would likely be an issue too.

Re: [RE-wrenches] Solar over a pool - what must I pay attention to?

[Jason Szumlanski]

See NEC 680.8. From what I have been able to determine, it's completely
unworkable to install solar modules over a swimming pool unless you can
complete enclose all conductors in raceway, and even then it would be very
questionable by AHJs I have asked.

I get this question at least once a week in Florida. Usually it's something
like, "can't I just install them on my pool screened enclosure." Um, no.
Have you seen what hurricanes do to those things? :)

What's interesting is that sometimes roofs extend over the edge of a pool,
or certainly within 10' of the lateral pool wall boundary. But solar panels
with exposed wiring above these roofs are allowed by AHJs, so I guess if
it's on the roof (or in the attic), the conductor is not considered
"overhead" or "exposed."

[RE-wrenches] Solar over a pool - what must I pay attention to?

[Howard Arey]

Greetings, Wrenches!

 

I have a client that wants one of our solar pavilions over their pool. We
have never done this and wanted to hear opinions on what code requirements
might be pertinent (or little known) for solar modules over water.
