EVs, Heat Pumps & Whole-Home Electrification
Planning solar and batteries around an electric car, a heat pump or a pool — and sizing for the home you will have, not just the one you have today.
Should I size solar for a future electric car?
If you expect an EV within a few years, it’s often cheaper to size the system for it now than to add panels later. A typical EV adds a few thousand kWh a year depending on miles driven. Charging overnight from the grid on a low-rate plan, or midday from solar, both work — your plan and schedule decide which is better.

Can a home battery charge my EV during an outage?
It can, but EV charging drains a home battery fast, so most families limit or pause EV charging during outages to protect essentials. Some systems can automatically manage that. Plan EV backup expectations in your sizing conversation.

Do I need a main panel upgrade for solar and a battery?
Sometimes. Older or smaller electrical panels may need an upgrade or alternative solutions to safely add solar, a battery, an EV charger or a heat pump. Your consultant should check your panel during the in-home review and include any upgrade cost in the proposal.

Does a pool pump or AC upgrade change my solar size?
Yes. A pool pump can add a lot of yearly usage, while a high-efficiency AC or heat pump can lower it. Tell your consultant about planned changes so the system fits the next 10 years, not just the last 12 months.
