Certasun
Responsible solar panels company. Great followup and responsive feedback from initial permit application to final installation completion. There is sufficient feedback information in each stage of the project. Any request for additional information or clarification is answered within 48 hours. For our system, the entire process took 6 months even it's going thru the winter months. Our solar system is up for running for 2 months now. The energy generated from the solar system is more than enough to supply our electricity demand. Approximately 20% extra is stored in the Grid for future use.

Very responsive and efficient
The CertaSun team were never pushy when my wife and I were going through the decision making process. They were very helpful giving us facts and reworking proposals a number of times. Once we purchased, they had a great app where the entire project was managed out of from a tracking perspective. Communication was still old fashioned by phone and email, which was great for me! The installation crew were very mindful when on our property taking care to not disturb our garden. They got done - very clean job. The inspector and they came a week later, and all was well. I have recommended them to several friends who are now interested after I shows them my month to date savings. We got installed on March 31st, 2023 and should have made this decision years ago.

Happy with the team, equipment and process, from start to finish. System details / pricing was accurate, system looks good, conduit is hidden, installers didn't leave a mess behind, etc. They handled the State credit, City permits and the HOA approvals, too. Will definitely be recommending CertaSun / SunPower to all the neighbors in our new development.

High Quality Solar Panels / Good Installation
As an Electrical Engineer, I was focused on getting the highest efficiency solar panels and the cleanest look on the roof. Certasun installation has NO conduits running on the roof. The crew was very efficient on installing the panels. The final installation looks great and performs as specified.

Powerful and reliable system
Certasun did a fantastic job installing our 12-panel Sunpower system on a challenging roof. The installation looks much better than most others I've seen - close to the roof and no exposed conduit. The system provides more than 90% of our electricity to date (most months Comed bill is $14). Installation inside was very clean with monitoring box mounted where requested. Have had zero issues in past two years - system just works and generates power. Certasun was also very helpful and detailed with the financing and IL rebate process which all came through as expected. Highly recommend!

Great
Everything was done well. Everything was explained. Installation was delayed for multiple reasons (some my fault), but eventually completed in a timely manner. A window was damaged in the process, but Certasun has promised to fix it.
