Data last verified: August 2026Clean 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.

Why a heat pump is the best solar load, how much extra solar it needs, and the combined savings.
Read the guide →How the pieces compound
| Component | What it adds | Why it pairs with solar |
|---|---|---|
| Battery | Evening self-consumption + backup | Stops wasting 5¢ exports; uses solar you already paid for |
| EV | ~3,500–4,500 kWh/yr new load | Solar electricity at 0–5¢/kWh beats gas at ~11¢/mile |
| Level 2 charger | Convenient 4–10 hr home charging | Makes the EV practical so the solar/EV savings actually happen |
| Heat pump | ~3,000–7,000 kWh/yr new load | Replaces 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.
