We are somewhat surprised by the amount of comment induced by the post on the solar array, so we thought we’d update you to the present (things are moving quickly).
Earlier in the week it became obvious that the roof over the upper deck would benefit from enhancement. The negative was shading at some angles on a portion of the solar array.
So, why not add a couple of compensating panels to the upper roof? Indeed.
If two, then how about 12? Sure, these are significantly less efficient due to shading from the masts, radar, and whips. But they’d be at least 50% as good as below, and possibly better than that in some conditions. That’s a 50% increase in usable power. We are still working out the shading factors, but we expect to be in the 25,000 and 30,000 watt range before converting to DC for charging the batteries.
Now we have enough for the air conditioning on a modest basis and to take care of domestic loads in less favorable seasons.
