What Should You Know About GRNE Solar

Founded by Eric Peterman, GRNE (pronounced “green”) stands for Global Renewable Natural Energy. Although GRNE was started just 10 years ago, collectively its people bring over two decades of renewable energy and green construction experience. The company has gained a reputation for professional and reliable services in the Midwest. As an EPC (Engineering Procurement Construction) company, GRNE has its own installation team and does not use subcontractors. Some companies, like Sun Badger and Tron Solar, even hire GRNE’s teams for their own installations.

GRNE is also a certified vendor for the Illinois Solar for All program, which improves low-income communities’ access to the clean energy economy with incentives that help make solar installations more affordable. GRNE also has a podcast called “Watts Up” that invites industry experts to share their innovations, solutions and knowledge.

GRNE Solar Services and Installation

GRNE offers installations for homeowners and businesses as well as utility-scale solar and is experienced in handling a wide range of solar system sizes. It also offers energy storage and is a Tesla Powerwall certified installer. GRNE’s lower-profile offerings include EV charging stations and project management services.

Solar Installation Experience

Partnering with GRNE on your solar system installation is straightforward. A typical residential installation experience goes as follows:

  1. When connecting with GRNE about your solar project, you will submit your address and phone number and most recent electricity bill amount.
  2. Based on the bill analysis and satellite imagery, GRNE’s design team will work out the amount of solar power you need and how much can be generated by your roof. The team will compile this information and a salesperson will reach out to you with a quote.
  3. If you are satisfied with the proposal and the pricing, you will sign a contract and choose a purchasing option.
  4. GRNE will handle all the permitting and incentives for your system, applying with the local jurisdiction, the local electric utility (such as ComEd in Illinois), and for any incentive or rebate programs.
  5. Once the necessary permits are secured, GRNE’s technicians install your system in a day or two.
  6. The installed system needs final approval from the local jurisdiction, which conducts an inspection to ensure it meets regulatory and safety standards. Once your system is approved, it can be switched on, providing you with clean energy for up to three decades.

GRNE Solar Customer Service

GRNE has experienced rapid growth, and its uncompromising customer service has helped it expand. Happy customers have described the company’s customer service as “first-rate” and “amazing.” Some have even reported GRNE granting discounts for installations that were delayed.

No matter how great a solar company’s reputation, its pricing can make or break a deal. GRNE doesn’t owe its popularity to its pricing, but prices are often close to average or even slightly lower. Many customers describe them as competitive. GRNE also has a referral program that scores you a $25 gift card for a qualified referral and $500 in cash if the referral installs a system.

With this in mind, GRNE offers an array of purchasing models, including loans and power purchase agreements (PPAs) with $0 up-front payments.

  • Equipment warranty: GRNE’s solar modules and inverters come with a 25-year warranty, while the batteries come with a 10-year warranty.
  • Workmanship warranty: GRNE provides a 10-year workmanship warranty on its installation that protects your system from faulty installation.

Positive GRNE Solar Reviews

GRNE’s positive reviews speak to the company’s professionalism, responsiveness and reliability.

“I couldn’t recommend them more highly. Every person I’ve had contact with has been professional and extremely helpful every step of the way, very conscientious and patient with all my questions. The install went great and the panels have been up and running for months now, working like a dream. Thanks GRNE!” – Christopher G., via Yelp

“GRNE Solar was fantastic! I had a very specific problem regarding a unique issue and the team was still willing to help out and solve my issue. They are a group of likable, passionate people that seek to make the world a better place. Wouldn’t recommend going anywhere else for solar installations or general help.” – Charlie K. via Kev’s Best

Negative GRNE Solar Reviews

The company’s negative reviews speak to the occasional poor instance of customer service.

“I was regularly underwhelmed by the customer service. I wrote repeatedly to various people and to some unclear overseer from another organization involved in Illinois solar installation. It regularly took weeks to get basic questions answered. The panels are in, they work fine, and we are getting some kind of rebate check, but it was literally 14 months from start to finish. Not impressed.” – Melanie H. via Google
