There are a lot of solar companies. Few are local, family-owned, and built to still be here in year 30 of your warranty. iSolar is.

Quality work, priced fairly.

Frequently asked.
Is solar worth it in Minnesota?
For most homeowners who own their roof and use enough electricity, yes. With the residential federal credit gone as of 2026, the math runs on your utility rate, Xcel Solar*Rewards where capacity allows, net metering, and cash or loan ownership — we don’t do leases or PPAs. Most Twin Cities-area systems pay back well within their 25-30 year panel life — run your own numbers with us. Run your own with our free Solar Payback Calculator or Solar Savings Calculator.
