Solar Panels Only vs Solar + Battery Storage
Solar-only systems run $15k–$45k pre-ITC but lose 70–80% of export value under NEM 3.0; adding a battery ($13k–$18k) recovers most of that and provides outage backup.
Solar for EV Charging vs Solar Panels Only
EV-sized systems (10–14 kW) cost $27k–$51k but offset both home and vehicle electricity; right-sizing to your annual kWh including EV miles maximizes the 30% ITC.
