Compare battery size, generator watts, fuel cost, fuel needed, and solar refill time for the same outage appliance plan.

Compare battery and generator backup costs using your outage hours, power load, fuel price, electric rate, and equipment costs.

Compare exporting extra solar with charging a battery, including efficiency, export credit, payback, and export-limited solar.

Estimate solar used at home, exported kWh, grid power needed, annual value, and extra EV solar charging value.

Estimate home battery TOU savings, mid-price shifting, and simple payback from your rates, battery size, efficiency, and cost.

Estimate battery payback using installed cost, cycles, peak/off-peak rates, export credit, incentives, and battery aging.

Estimate panels needed, system size, monthly production, roof space, roof fit, and rough cost from kWh use and sun hours.

Size off-grid solar panels, batteries, inverter, and controller, then check weak months with your own monthly sun hours.
