iSolar is a Minnesota-based licensed electrical contractor and solar installer with the goal of empowering customers to be their own power supplier. The company sets residential, commercial, and agricultural customers up for success with solar from consultation to design to installation.  


The Good

  • Industry and Experience 
  • Diverse Project Portfolio 
  • Agricultural Solar 
  • Solar Panel Warranties 

Industry Experience 

With more than four decades of experience in the solar energy industry, iSolar boasts a high level of experience, expertise, and reliability.

Diverse Project Portfolio

iSolar offers solar installations for residential, commercial, and agricultural properties, allowing potential customers from various sectors to benefit from its services.

The company has an impressive online project portfolio, showcasing its work in various cities, including the following Detroit Lakes, Saint Paul Park, Felton, Big Falls, St. Louis Park, and Minneapolis. This expansive portfolio demonstrates the company’s ability to handle solar installations on different types of properties and in different settings.

Agricultural Solar

Many solar companies are residential- and commercial-only, so iSolar's capacity for ground-mount agricultural solar projects sets it apart. 

Minnesota farmers may qualify for some federal grant opportunities to help make the switch to solar for their power, and iReady will walk customers through those opportunities. 

After installation, as a certified building and electrical contractor, iSolar provides ongoing performance operations and maintenance for ground mount panels in agricultural settings.  

Solar Panel Warranties

iSolar provides competitive solar panel equipment warranties of up to 30 years. This indicates its confidence in the quality and durability of the solar panels used, providing peace of mind for customers.

For reference, most solar panels come with a 25-year manufacturer’s warranty, so iSolar’s 30-year warranty products are above that of the industry average. 


The Bad

  • Unknown Equipment Partnerships
  • Unknown Workmanship Warranty 

Unknown Equipment Partnerships

The company does not disclose information about its equipment partnerships, including the brands of solar panels, inverters, and solar energy storage systems it uses. While we can assume iSolar uses top-notch equipment, some prospective customers may want specific details about brands and their specifications before moving forward. 

Unknown Workmanship Warranty 

iReady doesn’t list a workmanship warranty length or any other details regarding a workmanship warranty on its website.  

For context, workmanship warranties for solar cover the labor associated with solar installation, specifically roof penetrations from installing solar panel mounting racks. The industry average tends to be 10–12 years, with top companies offering a 25-year workmanship warranty, matching the length of a typical manufacturer’s solar panel warranty. 


The Bottom Line

iSolar appears to have several strengths, such as its extensive experience, diverse project portfolio, and competitive solar panel manufacturer’s warranty. 

While we recommend iSolar overall, potential customers may want to seek additional information and clarification on specific equipment, workmanship, and production warranties offered before making a final decision.

A great group of people to work with. Easy to talk to and very flexible. A good, clean installation. There has been no problems with the system.
