The night before the PV crew was to begin reconfiguring the array to prevent shading, the company’s designer sent two additional layout options — CAD diagrams as PDF, regrettably marked “not to be reproduced without written permission.” Apparently the initial redesign attempt didn’t meet generation expectations either.

We selected a design that best accomodates the area tree cover. The 24 modules will be split onto two racks (rather than the current five). A “shading study” shows the roof lit by the afternoon sun on the longest day of the year, December 20, to prove that the southern rack won’t shade the northern one.

Yesterday the crew disassembled the current system and built one of the two new racks. I realized that reinstalling solar is even more work than the initial installation; last December, the crew started with an empty roof.
