Royal Oak particulars
Royal Oak prices solar by the kilowatt on its Master Administrative Fee Schedule, effective July 1, 2025. It lists "Solar / Photovoltaic (per Kw)" at $20.00 under electrical, and the schedule's rule is to "Multiply the total quantity of each item by the unit price." A July 1, 2026 schedule is referenced on the city site, but its amount isn't printed here, so ask whether $20.00 still stands. Royal Oak sits in DTE Electric's territory on the MPSC map; confirm your address with DTE.
Size is the number to pin down. About 100 sq ft of roof per kW is what the Michigan Public Service Commission's consumer tips give for rooftop panels, and the city's fee runs on the same kW. Get the system size in kW DC from every installer, written on the quote. Royal Oak's building department (248-246-3210, per the city's page) takes code questions from its inspectors Monday to Friday, 8 to 9 a.m. or 3:30 to 4:30 p.m. One of those windows is the time to ask about the current per-kW amount.
Solar battery storage in Royal Oak: what to know
Storage kWh and export or nameplate capacity are left out of the 110 percent limit, and DTE says the system's total yearly generation or export must not rise because of the battery. Check with DTE that it serves your address.
Royal Oak's building department (248-246-3210, per the city's page) can tell you whether the battery needs a permit.
Permits for solar battery storage in Royal Oak
The 2023 National Electrical Code has been Michigan's electrical code since March 12, 2024, and LARA sends residential requirements to the Michigan Residential Code.
When to call 911 and when it can wait
- Smoke, a burning smell or fire at a battery, inverter, panels or wiring is a 911 call. Leave the equipment alone.
- The neighborhood is out of power and your panels with no battery are off, which is how grid-tied inverters are built to behave.
What to settle before you buy
Try this first: ask the installer how the battery is wired to the existing inverter, and get the answer on the quote.
- Decide what you want backup power for: a few circuits or the whole house.
- Ask whether the battery is priced inside or on top of the solar quote.
- Get the capacity in kWh, the warranty and the make and model in writing.
- Look up the company's electrical contractor license number with LARA.
What solar battery storage costs
The estimate below is the Michigan-wide one, adjusted for Michigan wages and not for Royal Oak in particular. The same table is on the solar battery storage page. How we estimate costs. Prices as of Oct 23, 2026.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $6,550 to $14,800 per home battery (about 10 to 13.5 kWh) installed, before any incentive | Built from 2 national published ranges, adjusted by the Michigan solar installer wage ratio (0.87). Before any incentive: there is no federal credit for a system installed in 2026. |
| Solar photovoltaic installer wage, Michigan mean | $24.29 an hour | What installers are paid (BLS OEWS May 2025), not what you are charged. Only 310 people are in the Michigan estimate. |
How we estimate costs: the Estimated range row comes out of a model, so treat it as a planning figure and never as a quote. It takes 2 published national ranges for this job (cost guides from third-party sites that we haven't verified and don't cite) and multiplies them by Michigan's solar installer wage ratio to the US (0.87, BLS May 2025). The range is before any incentive: the federal residential clean energy credit does not apply to systems installed after December 31, 2025. The wage and permit rows are what installers are paid and what the city charges, and neither is a price. We have not collected quotes, and too few Michigan installers publish prices to show a range.

Questions about solar battery storage
Will my solar panels work in a Michigan power outage?
Not without a battery, because grid-tied inverters shut off in an outage. The MPSC's consumer tips say backup power needs a battery.
Is there a tax credit or rebate for a home battery in Michigan?
Not a federal one for a battery finished in 2026. The Residential Clean Energy Credit ended for expenditures made after December 31, 2025, and installation completion is what counts.
Does a battery let me go off the grid?
Consumers Energy warns against claims that you can be independent of the grid, and says customers still have a bill for fixed charges.
