The sun gives, the evening takes.
Households with rooftop solar export their midday surplus cheaply, then buy expensive power in the evening peak and sit in the dark during outages. Most owners cannot tell how much battery they need, which loads to protect, or how a day of sun, use and storage fits together. Quotes are opaque, and monitoring apps show numbers without saying what to do.
