Solar Guides

Solar is the home-improvement category where the sales process and the engineering have drifted furthest apart. A system is a twenty-five year decision about your roof, and it is routinely sold in a single evening by someone who has never been up there. That mismatch is the reason so many homeowners feel uneasy about the whole category.

These guides are written to close that gap. What actually determines whether a roof is a good candidate, which questions expose a proposal built on assumptions rather than measurements, and what changes about production when the sun sits low and there is snow on the array.

What none of these guides can do is tell you whether solar makes sense on your specific roof. That answer comes from measurements and from twelve months of your own usage, and anyone offering it without both is guessing. What these can do is make you a much harder person to guess at.
