Solar Arrays. [RE-wrenches]

[marco mangelsdorf]

>From Dean Newbury:

When possible I mount PV over pool panels. Leaving 4" for ventilation
the same as a plane fo roof mount. We estimate 30% shading losses, so
add a panel or two to the pool heating to get the required insolation
for that system.

--Say what?!  Cover metal or plastic pool panels with PV modules?  Since the
very large majority of the heat produced from thermal panels comes from
direct insolation, how can it make sense to cover thermal panels with PV
modules?  I gotta believe that the shading losses is way more than 30
percent, no?
