Frequently Asked Questions
FAQ
Frequently Asked Questions
Which battery is better during a hurricane?
Both are excellent. The real difference is how much power you need and how long you want it to last.
Can I add batteries to an existing solar system?
Yes — both Tesla and Enphase can be retrofitted, though it’s cheaper and cleaner to add them during a new roof + solar project.
How long do these batteries last?
Tesla: 10-year warranty. Enphase: 15-year warranty. Both are designed for 10,000+ cycles (20+ years of daily use).
Do batteries qualify for any extra incentives in 2026?
They help with insurance discounts and can improve net metering efficiency, but the old federal tax credit no longer applies to homeowner purchases.
Is one brand clearly cheaper?
Pricing is very close in 2026. The best value usually comes from the contractor who can install both the roof and batteries together.
