One battery or two?
A homeowner uploads a year of SDG&E interval data and the page simulates 8,760 hours of solar and battery dispatch against their own meter, pricing four builds: no battery, one, two, three.
The idea. Every competitor recommends a battery. This one names the point where the next battery stops paying for itself and says so out loud — a position no competitor can copy without giving up revenue.
