Sunny Boy in the sun? [RE-wrenches]

[Gary Higbee]

Wrenches,

In doing inspections for the Energy Trust of Oregon we're seeing a lot of
Sunny Boys, of course. I'd appreciate your pass on whether we should allow
the units to be mounted on exposed locations in the sun--in particular West-
and South-facing surfaces. At present we lean towards requiring some sort of
sun shade (while still maintaining good air circulation).

We know about the importance of good air circulation, but what about
significant direct sun and hot ambient temperatures?

What's your pass? Has anyone done a test to see what derating occurs? Should
we allow unshaded Sunny Boys on these surfaces or not?

Thank you,

Gary
