The Good

  • Accreditations
  • Referral Program
  • No Surprises Guarantee
  • Warranty

Accreditations

Certasun is a SunPower Elite Dealer, signifying that SunPower has determined Certasun provides the highest level of quality and customer service in its solar installations. This partnership with SunPower ensures that every phase of the solar installation process, from initial consultation to final installation and inspection, is accompanied by an exceptional customer experience team and top quality service. The Certasun team will handle everything, including filing the necessary paperwork for permits, to ensure the entire process is seamless.

As a SunPower Elite Dealer, Certasun also installs some of the best solar equipment on the market, including high-efficiency solar panels and solar inverters. The company also provides solar energy storage and EV charging options as way to improve the solar system's overall efficiency and savings potential.

Certasun is also Illinois Shines Approved Vendor #1.

Referral Program

Certasun customers who refer someone else to the solar company will receive $500 after the referred person completes their solar installation.

No Surprises Guarantee

Certasun offers a “No Surprises Guarantee." The guarantee makes a number of promises to Certasun customers, including that Certasun employees will leave the customer’s home as clean or cleaner than when they arrived, that Certasun will give customers unbiased information about their financing options, and that customers’ solar power systems will perform as intended over the lifetime of the system. This guarantee should help increase potential customers’ confidence in working with Certasun.

Warranty

Certasun solar installations come with a 25-year warranty across the board. Because the company exclusively installs SunPower Equinox solar systems, every part of its solar power systems is under the same warranty, so there’s no confusion on which company is responsible for an issue.

Financing Options

Certasun provides homeowners with multiple financing options to help them make the switch to solar, including multiple solar loan programs, as well as its solar lease product. Loan options include traditional term loans with low monthly payments, as well as bridge loans that significantly reduce the upfront investment.

The solar provider also provides a solar lease, which does not qualify for state and federal tax credits, but does require zero money upfront and comes with low monthly payments.

The Bad

  • Limited Service Area
  • Residential Only
  • Exclusive SunPower Installer
  • Missing NABCEP Accreditation

Limited Service Area

Certasun serves only those homeowners located in northeastern Illinois, eastern Wisconsin, and southeastern Massachusetts.

Residential Only

While many solar companies work with residential, commercial, and agricultural clients, Certasun installs only residential solar power systems. 

Exclusive SunPower Installer

Certasun exclusively installs the SunPower Equinox solar system. While SunPower is a reputable solar brand, this choice does limit customers’ options if they install through Certasun.

Missing NABCEP Accreditation

Certasun does not appear to employ any NABCEP-certified technicians, which puts it at a disadvantage compared to solar companies that do. The North American Board of Certified Energy Practitioners is one of the most well-respected and sought after solar certification programs in the United States.

Limited Certasun Reviews

Unfortunately, few verified customer reviews on Certasun's products and services exist online. Verified Certasun reviews are crucial to establishing the company's online reputation and helping Certasun distinguish itself from different companies.

The Bottom Line

Certasun installs residential solar systems for homeowners in Illinois, Massachusetts, and Wisconsin. 

Certasun is a SunPower Elite Dealer and exclusively installs SunPower Equinox solar systems. On the positive side, SunPower is an extremely reputable brand with 25-year warranties, and Certasun’s practice of installing all the products in its systems from the same brand simplifies the warranty process for homeowners. On the other hand, those who are interested in products from other brands will need to look elsewhere.

Unfortunately, Certasun does not appear to employ any NABCEP-certified technicians. Many other reputable solar companies employ NABCEP-certified technicians, which indicates a high level of training, ethical standards, and continuing education.

The solar company also deals exclusively with residential solar power systems, while many other solar companies install commercial and agricultural systems, as well. Commercial and agricultural customers — as well as those who live outside Certasun’s service area — will need to work with another solar company.

But for residential customers who are interested in a SunPower solar system and live in northeastern Illinois, eastern Wisconsin, or southeastern Massachusetts, Certasun is an option worth considering.
