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.

Transparent, professional, not salesy
Certasun was fantatic. They were honest and transparent throughout the whole process. Sales people were not pushy or annoying. The installers were the nicest contractors I've ever had work on my house; and they worked their butts off too. The *only* wrinkle in my experience was that it took several months to actually get the panels. But that seemed to be more of an industry-wide issue, rather than just Certasun's issue. In the end, they gave me slightly higher wattage panels for no extra cost to get my panels installed sooner.

Solar panel installation
Certasun was outstanding to work with. The proposal included reasonable, even conservative, assumptions about system output given area weather conditions. They provided clear, detailed information throughout the process. The installation crew worked efficiently and kept the work site clean. Post-installation follow-up with local electrical inspectors and the utility was smooth and hassle-free for me as the homeowner. I would unreservedly recommend them to others.

Going Solar with Certasun...
Reputable, Knowledgeable, Professional... this is Certasun!! We interviewed three companies amongst much internet research and speaking with other couple's experiences and choose Certasun for the three keys mentioned above in addition to their affiliation with the solar panel manufacturer SunPower. The deciding factor was their offer including the state dollar credit from day 1 when other companies putting it on the purchaser to 'apply for' the state credit after an 18-month (+/-) performance period to assure the state that solar power production was actually being produced to the levels stated in the proposed work. This was key and said to us that Certasun was placing 'skin in the game' by ensuring this production from the very first day!!

Happy overall with my installation
Certasun was very much upfront starting from the presales process and transparent about every step of the process. Bill Wayne (salesperson) shared me every detail including slight increase in home owners insurance. Installation team did great job as well by showing the plan and discussing the need to change little bit as a result of vent introduced after the plan was prepared. Certasun did a great job from start to finish with our solar system installation. I am really happy I picked Certasun for this project.
