VI.FAQ

Solar & Battery — Frequently Asked Questions

Is solar still worth it under NEM 3.0?

Yes — but only when designed properly with battery storage. Solar-only installs under NEM 3.0 have payback periods of 12+ years, which is hard to justify. Solar plus battery, sized for your actual load profile, can pay back in 6–8 years and provides backup capability. We model the math for your specific home before quoting.

Do I need a panel upgrade to add solar and battery?

Sometimes. Panels rated 200 amps with available bus space generally handle solar interconnection. Older 100-amp panels and panels at capacity often need an upgrade or a load-side tap solution. We verify panel capacity at design and quote upgrades transparently if needed.

How long does a solar + battery installation take?

From signed contract to system turn-on, expect 8–14 weeks total: 2–3 weeks design and permit submission, 3–6 weeks permit and utility approval, 1–2 days installation, and 2–4 weeks for utility Permission to Operate. The actual on-roof installation is the fastest part of the process.

Will my system work during a power outage?

Only if you have a battery. Grid-tied solar without battery shuts off automatically during utility outages (an anti-islanding safety requirement). With Tesla Powerwall, Enphase IQ, or similar battery systems, your home stays powered through outages — duration depends on battery size and load.
