Solar-Ready Electrical Work in the Twin Cities
Most solar projects fail or stall because of the electrical work behind the panels, not the panels themselves. A solar array is only as good as the service panel it ties into, the conduit it runs through, and the interconnect it’s inspected against. We handle that side of the install — the part that has to be done by a Minnesota-licensed electrician.
Three Rivers Electric is the electrical division of iSolar Minnesota. If you want a full solar installation, that’s iSolar — same team, same trucks, dedicated solar focus. If you want a licensed electrician to handle the panel upgrade, sub-panel, conduit runs, or interconnect prep that goes with a solar array (or a battery, or an EV charger), you’re in the right place.
Will your panel handle a solar interconnect?
A solar tie-in plus modern loads can push an older panel past its limit. Check your service panel’s headroom in two minutes before you commit.
What “solar-ready electrical” actually covers
- 200A service panel upgrades — most homes built before 2000 have a 100A or 125A panel that won’t safely handle a solar interconnect plus modern loads. We upgrade to 200A with the right bus rating and proper backfeed-breaker capacity.
- Sub-panels and critical-loads panels — for battery backup setups, we install a separate sub-panel that holds only the circuits you want running during a grid outage (furnace blower, fridge, well pump, a few outlets).
- Service mast and meter base replacement — old service masts often can’t pass Xcel’s interconnect inspection. We replace them ahead of the solar install so there are no surprises on inspection day.
- Conduit runs from roof to inverter to panel — clean EMT or PVC runs, properly bonded, with the right wire gauge for the array size. No spaghetti, no shortcuts.
- EV charger circuits that integrate with solar — if you want your EV to charge off your solar production, the circuit has to be sized and located correctly. We handle the 240V circuit; iSolar handles the inverter coordination.
- Xcel interconnect inspection prep — Xcel rejects more solar interconnects for electrical reasons than for solar reasons. We walk the system before the inspector shows up.
- Whole-home surge protection for solar systems — solar inverters and battery systems are expensive enough that a Type 2 SPD at the main panel is cheap insurance.
When you need us vs. when you need iSolar
- You’re planning a solar install in the next 6 months and want your panel sized correctly before the installer quotes you.
- You already had solar installed and Xcel flagged something on the electrical inspection.
- You want a battery backup added to an existing solar system and need the critical-loads panel installed.
- You want an EV charger circuit that’s compatible with future solar.
- You want a permit-pulled, code-compliant electrical setup that’s ready for any solar contractor to tie into.
- You want a full solar installation — panels, inverters, financing, monitoring, the whole package.
- You want a battery backup system designed, financed, and installed end-to-end.
- You’re comparing solar quotes and want a contractor who’s been in renewable energy since 2019.
- You’re shopping for solar in Minnesota and want to start with a free site assessment.
Frequently asked questions
Can you do my whole solar install?
For the full solar package — panels, inverters, monitoring, financing — we hand that to our sister company iSolar Minnesota. Same team, same address, just a different brand because solar work and electrical work are different specialties with different inspection regimes. Three Rivers Electric handles the electrical-only side: panel upgrades, sub-panels, conduit, interconnect prep.
Will my solar contractor accept your electrical work?
Yes. We pull the permit, the work is inspected by the Minnesota Department of Labor and Industry, and the documentation is what every solar contractor needs to tie in. If your solar contractor is iSolar, the handoff is even simpler — we’re already in the same project file.
Do I need to upgrade my panel for solar?
Usually yes if you have a 100A or 125A panel. Solar interconnect rules limit how much backfeed breaker capacity your bus can handle (the “120% rule”), and a 100A panel doesn’t leave enough room for most modern solar arrays. A 200A upgrade also future-proofs you for EV charging and battery backup.
What does a solar-ready panel upgrade cost in the Twin Cities?
Most 200A service panel upgrades run between $2,800 and $4,500 depending on the service mast condition, meter base, and grounding. We give a fixed quote after a 20-minute walkthrough — no surprise charges.
Are you affiliated with iSolar?
Yes — same ownership, same crew. John Ihle (Master Electrician, MN License EA761814) and Ryan Ihle co-founded iSolar Minnesota in 2019 and launched Three Rivers Electric as the dedicated electrical division in 2025. We split the brands so customers can find the exact specialty they need without the marketing noise of trying to be everything.
