The weather has been quite cold yesterday and today (upper 30's, low 40's), but yesterday's wind has subsided today, and it was quite workable. Thus, the installing crew diversified their tasks because as the mechanical attachment continues, the strings of panels need to have cables routing the electricity to combiner boxes. 7 panels attach in series to form a "string". 8 strings come together in a "combiner". The combiners then come to a junction box, and the cable runs to an inverter. The layout of the panels on the roof involves not only how many can physically be placed in the space, but how they connect electrically in the most efficient manner.
