Field notes
The sizing tool converts daily use and desired outage hours into kWh and 13.5 kWh example units; the cost workflow then factors in installation cost, bill savings, and only confirmed programme payments. The page also includes appliance-load and EV-panel checks, plus battery-runtime, warranty-cap, and solar-recharge tools. It says calculator inputs stay in the browser and directs readers to official utility sources and licensed installers for decisions.
