SUNNY home energy estimator
Build a preliminary solar battery quote estimate.
Use your bill, solar, evening usage and property to estimate capacity, installed price, savings and payback. It takes about two minutes and is not a binding quote.

What affects the result
The same bill can need a different battery.
A daytime-heavy home may use solar directly and need less storage, while an evening-heavy household may benefit from more capacity even when today’s bill looks similar.
The estimator uses your answers to select a capacity path. SUNNY’s team then checks interval data, inverter compatibility, switchboard, export limits, cable routes and backup circuits before issuing a written quote.
