How to install a photovoltaic array in a few simple steps:
Build a support rack for the PV modules. As you can see, our panels will be standing up from the roof, at an angle and direction calculated precisely to catch the most sun during those critical peak generation hours. We could have instead chosen a flush-mount design, but the reduced electrical output would have extended our payoff date by a year. (!) The angle is easier to see from below.I watched the crew in awe today. I can’t imagine a less fun job than working on someone’s roof, fully exposed, during a cold rain, bolting a steel rack together. OK, wait, I can too. These are hearty souls, though. They were cheerful about it all. They put in a full day’s work up there in the drizzle.
