Frequently Asked Questions
How many Powerwalls do I need for a Florida home?
For whole-home backup (running AC, refrigerator, lights, and basic loads) through an overnight outage, most Florida homes of 2,000–3,000 sq ft need 2–3 Powerwalls. One Powerwall can power essentials (refrigerator, lights, phone charging, one room's AC) for 8–12 hours during a typical Florida summer outage.
Is solar battery storage worth it in Florida?
Yes for most Florida homeowners — Florida's net metering policy changes (2023 NEM 3.0 transition) reduced the value of grid export, making self-consumption storage more economically attractive. Additionally, Florida's frequent hurricane outages make backup capability a genuine quality-of-life and safety issue, not just an economics question.
Does the federal solar tax credit apply to batteries?
Current federal note: the IRS says the Residential Clean Energy Credit is unavailable for residential property placed in service after December 31, 2025. Do not subtract the former credit from a 2026 residential proposal.
