Frequently Asked Questions
While the federal residential solar tax credit expired at the end of 2025, California homeowners still have access to several valuable programs.California’s property tax exclusion for solar energy systems means your solar installation does not trigger a property tax reassessment. Lease and Prepaid PPA financing options may allow access to the commercial 30% Investment Tax Credit through third-party ownership. Contact our team for guidance on which incentives apply to your specific property and situation.
Yes – solar is still worth it in California in 2026, even after the federal residential solar Investment Tax Credit expired on December 31, 2025. California utility rates are averaging around $0.347 per kWh and rising approximately 5% annually, which means the financial case for solar continues to strengthen each year. The key shift is that pairing solar with battery storage is now more important than ever – maximising self-consumption under NEM 3.0 delivers significantly greater savings than exporting energy back to the grid. Lease and Prepaid PPA options may still allow access to the commercial 30% Investment Tax Credit through third-party ownership – consult your tax advisor for guidance specific to your situation.
Under California’s NEM 3.0 net billing structure, excess solar energy exported to the grid is compensated at a significantly lower rate than under previous programs – averaging around $0.05 to $0.08 per kWh rather than near-retail rates. This makes battery storage essential for California solar owners in 2026. By storing your solar energy and using it during peak evening hours rather than exporting it, you maximise self-consumption and avoid purchasing expensive grid electricity when it costs most. A properly designed solar and battery system remains one of the strongest energy investments available to California homeowners and businesses under NEM 3.0.
California AB 942 is a state law that directly affects homeowners currently enrolled in older NEM programs. Starting July 1, 2026, customers who have been on their existing NEM tariff for 10 or more years will be forcibly transitioned to the state’s latest NEM version, currently NEM 3.0. Nabu Energy This means reduced compensation for solar exports and exposure to non-bypassable charges that legacy NEM customers were previously exempt from. If your solar system is approaching or has passed the 10-year mark, now is the time to evaluate adding battery storage to maximise self-consumption and protect your long-term savings under the new tariff.
Yes. Nabu Energy manages the complete permitting process on your behalf – including city building permits, HOA submissions where required, and utility interconnection applications with PG&E, SCE, and other California utilities. Our in-house team has extensive experience navigating California’s permitting requirements across multiple counties, helping ensure your system passes inspection on the first submission and reaches interconnection as quickly as possible.
Yes. Battery storage can be added to most existing solar PV systems in California. Our team assesses your current system’s inverter compatibility, electrical panel capacity, and energy usage patterns to design a battery storage solution that maximises your solar self-consumption and backup power capability. Given California’s NEM 3.0 structure, adding battery storage to an existing solar system is one of the highest-return upgrades available to California homeowners right now.
No. Every Nabu Energy installation is carried out entirely by our own in-house team. We do not use subcontractors at any stage – from system design and permitting through to installation, inspection, and interconnection. This means consistent quality, a single point of accountability, and no risk of becoming a “solar orphan” if a third-party installer goes out of business.
Most residential solar installations are completed within one to two days once permits are approved. The full timeline from consultation to system activation – including permitting and utility approvals – typically ranges from two to eight weeks depending on your utility, county, and whether electrical upgrades such as a main service panel upgrade are required.
