Guides

Longer guides organised around a decision rather than a single question: what to back up, when to re-roof, and whether you need solar, storage or both.

What a guide is here, and when to read one instead

A guide covers a decision that takes more than one answer to make — sequencing a roof replacement around an array, planning backup power before hurricane season, working out whether storage without solar makes sense for your house. If your question has a direct answer, the answers section is faster and gives it to you in the first paragraph.

Each guide states what it assumes about your situation, and each is written to be useful to someone who decides not to buy anything. That is deliberate: the parts most likely to be left out of solar content are the ones that argue for waiting, and those are often the parts that save the most money.

Every time-sensitive fact carries the date we last verified it and the source it came from. Solar content ages badly — the federal tax credit changed in 2025 and a great deal of published advice still assumes the old rules — so a guide without dates on its numbers is not doing you a favour.
