  • Aiming requirements

    One of the local electric providers is offering some incentives, but their aiming restrictions can be hard to meet. Basically, we need to be within 15 degrees altitude and 20 degrees azimuth for the customer to get the incentive. That's easy with a ground mount, but somewhat trickier when you're dealing with a roof mount on a roof that's not within at least the azimuth range.
    We're at 32.5N, so what we have to work with is basically 18-47deg elevation and 160-200deg azimuth. One of the customers wants roof mounts on two 3:12 roofs with ridges running 347deg and 60deg. Another has a similar pitch with the ridge running 320deg. With angled mounts, it's possible, but not very efficient and the quickest way we've found to find the angles is modeling it in Sketchup and rotating the modules until they fit. The result looks a little goofy, too, since anyone looking at it would swear those panels can't all be aimed at the same place. These are both fairly large jobs, so we're willing to do the extra work to try to accommodate the customers, but of course, anything that improves our efficiency is good.
    Just wondering if anyone else has run into this type of situation and how they solved it.
