Common Questions

Frequently Asked Questions

One Powerwall (13.5 kWh) powers critical home circuits for 8–24 hours depending on usage. For whole-home backup during extended outages, 2–3 Powerwalls are recommended. With solar charging, the system can run indefinitely.
Yes. Battery storage paired with solar qualifies for the full 30% federal ITC. Standalone battery storage (not paired with solar) also qualifies for the ITC starting in 2023 under the Inflation Reduction Act.
In most cases, yes. We assess your existing inverter system and recommend the most cost-effective battery integration. Enphase and SolarEdge systems have the most straightforward battery add-on paths.
Tesla Powerwall systems run $8,000–$15,000 installed depending on number of units. Enphase IQ Battery starts around $6,000 for a single 5 kWh unit.
