Certasun

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!

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.

Total Quality Service

Certasun provided courteous, informed and professional service throughout the installation process of my solar panel system. Excellent presentation, technical expertise and liaison support. The only "full service" solar company I know of.

The process to install solar panel was smooth.

The install crew finished in one day and cleaned after themselves Certasun did everything necessary from obtaining permits to getting the city approving the installation I am very satisfied

Enjoying Sunny Days Even More

Their estimate came with the best panels and quote. There was a break in their schedule and they fit us in early. Everything was installed professionally. Looks great and when others are telling me that the price of electricity was skyrocketing, I would say there is an alternative.

Happy overall with my installation

My solar panels were installed without problems and in a quality manner. I have already seen significant changes to my electricity bill.

Professional and friendly.

Certasun was very upfront and transparent about every step of the process. There were some delays that really happened because of my local municipality taking pretty long to approve and issue permits. Then ComEd also took their time to approve the project. Certasun staff were there with us every step of the way. My experience so far is that they use the top of the line products and are the top rated installers in our state. I am the type of person that looks up 8 to 10 companies. Certasun beat the competition even price wise. If you are looking for solar panels in the state of Illinois, you should definitely give them a call.

Great experience.

The salesperson prepared us for every detail and not just the good stuff (she told us our home owners insurance would increase slightly due to solar). Certasun has its own installers. When our roofer did some work on our house for unrelated reasons he commented that the installers had done a great job on our solar installation. One year after installation we got the promised results. It feels good to do our part, however small, by relying on solar power. We're glad we chose Certasun to make it a reality.

Certasun Solar System

Certasun did a great job from start to finish with our solar system installation. Paul did an amazing job explaining and answered all questions we had regarding solar system before installation. And installation team did great job as well. They hid the conduit pipe to the side of the house the way I wanted it.

Great service

If everyone does the job as these guys we would be a different world. Excellence at all levels. I am so happy I picked Certasun for this project. Thank you the installation team. They are the best!!!

We highly recommend Certasun.

We found that from the start of the project, beginning with the initial consultation to the final hook up of our system that Certasun was professional, extremely pleasant and patient to work with, and considerate in all aspects of this process. All the steps leading toward getting our system up and running, including helping us with our HOA contract, setting up county inspections, installation, obtaining state rebates and filing for tax credits, as well as answering our many questions we felt were exceptionally well handled. We are happy to be doing our small, but important, part to help the environment in our community and state of Illinois. We highly recommend Certasun Solar.

No more ComEd bills this summer!

Normally we pay $150/mo for coal-generated electricity from ComEd in the summer months because of air conditioning. Now, our panels are making all the electrical power, carbon-free, for us and the extra is stored with ComEd through the net metering program. We are storing away sunshine for cloudy days! If ComEd power goes out, our solar panels will continue to give us electricity! Our panels give us the energy first and any extra goes to ComEd for storage that will be given back to us when our electricity demand exceeds what the panels can give us. Our summer ComEd bill is $30 now. ALL THIS BECAUSE OF CERTASUN! We have been wanting solar panels for years for one reason: to help be a part of the solution to stop emitting carbon. Solar panels were always so expensive in the past. But, now with state and federal incentives, solar panels are 1/2 price. This past January, 2022, I looked at the Illinois Shines website and saw lots of vendor choices for solar panels. We called several vendors but weren't ready to commit to them. Frankly, it was overwhelming. I was nervous that vendors would stand behind their product. Luckily, my husband heard an ad for CertaSun on NPR and I gave them a try. I was not disappointed. Bill Wayne, Senior Solar Consultant, was excellent. He spent all the time that we needed to answer our questions and he gave an excellent presentation. Way better than any of the solar presentations I had heard previously. We pestered him with lots of emails and phone calls and he responded every time and was patient and extremely informed on the solar landscape including state, federal, and local regulations and incentives. If it weren't for Bill Wayne, I don't know if we would have solar yet! Certasun staff kept their promises, sent us the paperwork, and followed through in the time period promised. And as promised, It took 3 months from the initial contact to installation. Staff were knowledgeable, professional and really easy to talk to. Neighbors, and people driving through the neighborhood, including the skeptical ones, are constantly asking us about the panels and admiring how they look. I don't know how many times I have heard "I think we are going to look into it too!" My next door neighbor is very particular on how things look and she always reminds us how pretty the solar panels look on our roof. Not to mention, the value of our house increased by 4%...we checked Zillow. This investment is a win-win. We win with low energy bills and zero carbon emissions and our neighbors and surrounding community wins because of increased homeowner value. I highly recommend CertaSun. Great company. Love the Sun Power app that tracks our energy usage and the power from the sun. Sun always wins! For example, our 1 month home usage is 610 kWh. The solar panels are generating 774.4 kWh = 127%. The extra energy is being sent to the grid and is being stored by ComEd for us when days are cloudy or at night. The savings for September is $58.37 = 62 gallons of gas. Impressive. Oh! And CertaSun guarantees production! For us, they guarantee annual 112%.

Great experience

Certasun made the process very easy, and the installation was professionally done. I especially like the 25 year guaranteed kWh guarantee, where the last 5 years is only 5% less than the first 5 years.

Start to Finish, knew what was coming

From the low pressure sales call to the final permit inspection, I was kept informed of all that was going on. Longest part of the process was getting the building permit, after that the installation(one day), testing, and final sign off happened within weeks. Installation crew was here on time, were always professional and cleaned up well after themselves. Certasun was not the cheapest but have the best guarantees and the best rated products. I am very happy with how the whole process was handled!

Great Company to work with

No hassles. Everything explained upfront. Solar units producing as advertised. So far no issues

We had our 14 panel solar system installed by Certasun on September 15, 2018. We have since than saved $1610.20, 17 tons of CO2. Planted the equivalent of 264 fully grown. Not driven 39327 miles and saved 1783 gallons of gas The system is amazing which the above data proves.

Happy with results!

Up front sales with Dan was hassle-free and very transparent. Through that process learned all about third-party aggregators that many other installers use (CertaSun doesn't), which was very good information to have. Upon installation the crew (Jeff, Matt, David, and Corey) did a phenomenal job. They asked all the right questions, provided me with the right information upon request, and kept the area they worked in clean and tidy. They even removed an old light fixture that had been under the eaves of our roof, which helped make the installation cleaner aesthetically, and removed an old eyesore I had never gotten around to taking care of. Top notch guys, top notch work. A word of advice if you're considering solar: Plan on it taking up to six months from the time of contract signing to your first electric bill with solar savings. I signed in March and got my first bill in August, which meant I missed most of the best solar production for this year (and the resultant savings/credits)!

Quality Product and great Company

Very professional with project management that made the process easy with excellent communication every step of the way. I spent a lot of time researching products and installers. Definitely the best in the Chicago area.

I love my solar

From the start, Certasun was a class act. I was able to ask as many questions as I could think of in the beginning to fully understand how solar works in Illinois. Paul was a great help here, as he spent an extra hour (or two) explaining about SRECs and the installation timeline. Once the permitting was done, installation itself was done in a single day (mostly morning) by a great crew who themselves were very willing to share details about the process and how much they loved working for Certasun. The panels look great on the roof. After a few days the system was inspected and turned on to start collecting immediately afterwards. Almost 2 weeks later we have collected over 500 kWh and everything is smooth sailing.

Happy Homeowner - Grayslake

6.54 kW system installed on time in December 2020. Excellent service all around. Certasun took care of applying for the SRECs.

Highly Recommended

I was extremely happy with my experience with Certasun Solar. The initial sales consultation was informative but not aggressive. All of my questions were answered thoroughly. Follow-up questions were answered in a timely manner. The process from engineering to permitting to installation went exactly how they laid it out. The installation crew was thorough and professional. The system looks good on the roof and is up and running. It's too soon to confirm the amount of savings but I'm confident the estimates will be realistic. Overall a very good experience. I would highly recommend using Certasun Solar.
