Clean Energy Hub: Solar + Battery + EV + Heat Pump

Direct answer
Rooftop solar is the anchor, but the real savings come from what you power with it. A home battery shifts daytime solar to evening use and adds backup; an EV turns your panels into ~5¢/mile fuel; a Level 2 charger makes that practical; and a heat pump moves heating/cooling onto solar electricity instead of gas. Together they cut combined energy bills 60–90% and shorten solar payback — especially in 2026, with the federal residential credit gone and electrification load doing the heavy lifting.

🔋 Home Battery Payback

Does a battery pay off in your state? Critical for NEM 3.0 states where exports are cheap.

How the pieces compound

ComponentWhat it addsWhy it pairs with solar
BatteryEvening self-consumption + backupStops wasting 5¢ exports; uses solar you already paid for
EV~3,500–4,500 kWh/yr new loadSolar electricity at 0–5¢/kWh beats gas at ~11¢/mile
Level 2 chargerConvenient 4–10 hr home chargingMakes the EV practical so the solar/EV savings actually happen
Heat pump~3,000–7,000 kWh/yr new loadReplaces gas furnace with solar electricity — biggest single electrification load

Start with the calculator, then the guides

If you already have (or are sizing) solar, the two calculators above show the dollars. The two guides below fill in the real-world costs and sizing — charger installation by region, and how much extra solar a heat pump needs. All figures are 2026 market data; verify installer quotes for your exact home.

Disclaimer: Cost ranges are 2026 national/regional installer averages (EnergySage, Forbes Home, This Old House) and efficiency figures from DOE/EnergyStar/NREL. Your actual cost depends on your electrical panel, distance to the panel, and local labor rates. Not a quote. Retrieved Aug 2026.
