Panel Upgrade
Replacing a home's electrical panel with a higher-capacity one (typically 100A to 200A) to accommodate additional electric loads like solar, battery, EV charger, or heat pump.
Why It Matters
Many older homes have 100A or 150A panels that can't support solar + EV + heat pump. A panel upgrade costs $2,000-$4,000 and may qualify for a 25C tax credit or HEEHRA rebate.
