Main Panel Upgrade for Solar Cost: What You Will Pay in 2026
Written by HyreSolar Research Desk Price compilation from published, dated sources
The short answer
Main Panel Upgrade for Solar Cost depends mainly on the panel's current rating, whether the meter and service entrance must change, and local permit and utility rules, and this page gives the installed range from dated, sourced quotes.
Across 14 published, dated sources retrieved October 22, 2026, a main panel upgrade for solar, usually to 200 amps, runs $1,650–$4,000.
It is priced on its own line, on top of the solar system. No 30% federal credit applies to a system a homeowner buys: Section 25D ended for expenditures after December 31, 2025 (what changed).

What moves the price of a panel upgrade
Scope moves the price most. Swapping the panel itself is the cheaper job.
When the meter base, service entrance cable or the utility's service drop must also change, which is common on older homes with 100-amp service, the job adds utility coordination and can more than double.
That is why one source prices a full service upgrade separately from a panel swap, and why the top of the published range is far above the bottom.
Why solar triggers it matters. Solar feeds power back through a breaker on the panel's busbar, and electrical code limits how much backfed current a busbar of a given rating can take; a small or old panel often cannot accept the solar breaker as sized.
A larger system, a battery or a planned EV charger or heat pump pushes the same way. Our panel upgrade check works through the numbers for your panel.
There are sometimes cheaper routes. A supply-side (line-side) connection, a main breaker derate, or a smaller system can avoid the upgrade where the utility and inspector allow it. Region matters too: permit fees, utility scheduling and electrician labor rates differ widely, and California and Northeast installers publish higher ranges than national cost guides.
Price by scope
| Your situation | What the job usually includes | Read |
|---|---|---|
| Panel can accept the solar breaker | No upgrade; breaker and conduit only | Installation cost |
| 100 or 150 A panel, service adequate | New 200 A panel, permit, inspection | Panel upgrade check |
| Old meter base or undersized service cable | Panel plus meter base, service entrance, utility work | Ask for each item priced separately |
| Adding a battery as well | Panel sized for backup loads | Panels with battery |
How to check a quote
- 1Ask why the upgrade is needed, in numbers
The installer should show the panel and busbar rating and the solar breaker size that do not fit. Check them with the panel upgrade check.
- 2Ask whether a supply-side connection or derate was considered
Where the utility and inspector allow it, either can remove the upgrade from the bill.
- 3Get panel, meter, service entrance and permit priced separately
A single lump sum hides whether you are paying for a panel swap or a full service upgrade.
- 4Keep the upgrade out of the solar cost per watt
Divide only the solar price by the system watts, or the quote will look dearer than it is (cost per watt).
