Solar panel payback and sizing, home batteries, and backup power — the evergreen math, no incentive chasing.
Yes — and cold makes panels more efficient. Why winter output really drops, and what snow does to production.
Panels last 25–30+ years — here's how output fades, what actually wears out, and what the warranty guarantees.
When dirty panels are actually worth cleaning, the safe step-by-step method, and what never to use on the glass.
What actually sets the number of panels — your usage, local sun, and panel wattage — plus typical system sizes and how much roof space they take.
What a solar panel and a full system actually generate — daily and yearly — plus why output swings by season and fades slowly over the panels' life.
The payback math behind solar — sun, your rate, install cost, and usage — and how to tell whether panels actually pay off for your home.
What a home battery actually does, how to size it for backup, and how it stacks up against a generator for keeping the lights on.
