Your export rate is a council decision, not a regulator decision
The Net Billing Tariff that reshaped California solar economics from 15 April 2023 applies in the territories of the large investor-owned utilities. The CPUC page setting it out says its content applies to PG&E, SCE and SDG&E.
Roseville Electric is owned by the City of Roseville and is not one of those, so none of it binds your account. What governs instead is the city own rate structure, adopted and revised by the City Council.
That is a genuine advantage in that it has spared Roseville customers the export collapse seen elsewhere in the state. It is also a different kind of risk, because a council can revise a rate on its own timetable without the notice and process a CPUC proceeding involves.
The city says as much in the programme material: the net surplus energy compensation rate is subject to revision by the city council as energy prices and system requirements change. Treat the rate as current policy rather than as a locked term of your purchase.
Published figures disagree, so confirm before you sign
The city Roseville Solar 2.0 page states a net surplus energy compensation rate of $0.0691 per kWh, applying to customers interconnected on or after 1 October 2018.
The rate schedules and municipal code material carry higher and later figures, including $0.1176 per kWh effective 1 June 2024 and $0.1469 per kWh effective 1 January 2025.
Those cannot all be the operative rate today, and the difference between roughly 7 cents and roughly 15 cents is large enough to change whether a system makes sense at all. We are not going to guess which is current.
So ask Roseville Electric directly what the net surplus energy compensation rate is for a system interconnecting now, get it in writing, and check it against whatever figure your installer used. This is a ten minute phone call that can move a payback estimate by years.
How the meter treats your generation
Roseville Solar 2.0 uses a multi-register meter that measures the energy delivered to the grid after serving your instantaneous load. Self-consumption is settled first, and only what is left over is treated as an export.
That ordering is favourable and it is the reason self-consumption is worth more than export here, as almost everywhere. Electricity you use as it is generated displaces a purchase at your full retail rate; electricity you send out earns the surplus compensation rate instead.
Eligibility for the residential NM-1 schedule is framed around customer generators with a maximum yearly demand of 10 kW or less, and qualifying systems are capped at 1,000 kW and at no more than 100 percent of the customer annual energy usage.
That 100 percent ceiling is stricter than the 115 percent some California utilities allow, so a system sized against future load rather than historical usage may not qualify as designed. Ask how the cap was calculated for your address.
What the federal change did to the arithmetic
The 30 percent Residential Clean Energy Credit under Section 25D expired for property placed in service after 31 December 2025, so a cash or loan purchase now does not receive it.
That removes roughly a third of the effective subsidy that most published payback figures assumed, and much of the material still circulating was written before the change. A quote applying it is not describing a project you can actually buy.
Section 48E remains available at 30 percent to third-party owners, which means a lease or power purchase agreement provider can still claim it. Whether any of that value reaches you depends on the rate they offer, so ask them to show the comparison rather than assert it.
The California Active Solar Energy System Exclusion still keeps the added value of a qualifying system out of your property assessment. That is a state provision, unaffected by which utility serves you, and worth confirming with a tax advisor.
