Electrical Service to Ag lot/Contractor's Service
#13

Interesting thing about being in the tropics, the north side of your house will actually see sun during the longest days of the year.

Hilo is somewhere around 19 degrees (too lazy to confirm at moment), and the sun varies +/-23.5 degrees throughout the year. In FF you'll probably still grow moss on the north side. In FF with any kind of shade trees, you'll probably grow moss on the south side too ;-)

On the south face, the steeper pitches will work better in the "winter", and not so well in the summer. Again, going with 19N, a pitch of 42.5 degrees would get optimal sun exposure on the shortest day of the year, and something like 68% insolation on the longest day of the year (cosine of a 47 degree angle...)

If you go up to a pitch of 24 in 12 - 63.5 degrees, then you're looking at incident sun angles between 21 and 68 degrees, or 93 down to 37 percent insolation - not ideal, but not totally dysfunctional.

.....

Thanks for the Heart update... I traded e-mails with him about joining his engineer's commune on Bahia Ballenas Costa Rica, it probably would have been a better move for the family than the one we made to Houston - if our newborn didn't get eaten by a Jaguar.
