If rising bills sound familiar
The pain — and the fix
Waiting has a cost
If the exclusion changes in 2027, new systems may not get the same property-tax treatment.
Completion matters, not just signing
The date that counts is when the qualifying system is completed — so leave room for permitting.
Ownership plan, not a scare pitch
We’ll show clear numbers and a realistic schedule. No fake timers — just the statute calendar.
Real installs. Real crews.

Questions, answered
How long does a free assessment take?
About a minute online. An Option One specialist calls shortly with numbers for your address.
Do I need a battery under NEM 3.0?
For most SoCal homes, yes. NEM 3.0 pays little for export — a battery lets you use daytime solar at night instead of buying power back at full retail.
What’s different about owning vs a lease/PPA?
You keep the savings and incentives. Leases/PPAs can look cheap monthly until escalators and the 25-year total — and you often still don't own the system.
What is the Dec 31, 2026 property-tax deadline?
Qualifying systems completed by Dec 31, 2026 can lock in today's exclusion. After that the rules change — start while there's time to permit and install.
