Would have given 2 stars, but Eric was amazing throughout the process

December 21st, 2022 - Agreement for 17 Q Cell panels signed. Told that the project would easily be done by May and potentially earlier if the weather cooperates. February 23 - Told our garage can only hold 4 panels instead of the 17 originally quoted. We request cancellation of project March 23rd - Windfree reaches back out and garage can now hold 12 panels. Project back on and new contract signed April 11th - Windfree sends application to We-Energies (why did it take over two weeks? I don’t know) May 9th - Receive invoice for ordering of panels per contract. I request an itemized list of what will be ordered. I find out they switched out the panels from the requested QCell panels to the REC panel. To swap out a major component without notification is EXTREMELY bad business. May 23rd - wiring diagram/one-line sent to We-Energies May23 -June 23rd - We-Energies denies MULTIPLE versions of Windfree’s wiring diagrams and includes notes of what needs to be changed. Windfree seems to ignore the notes that We-Energies includes with each rejection. June 23rd - wiring diagrams finally approved August 15th - Windfree attempts to add $2600(20% project increase) to the invoice to cover the cost of a dual meter pedestal We-Energies had required from the beginning. We do not agree to pay this additional fee. August 28th - solar panels are mounted September 18th - Meter wiring takes place (Windfree subcontracted it out) October 3rd - System fails inspection. Wiring that took place didn’t match diagrams. November 3rd - Another Full month of generation lost. Meter wiring takes place….for the 2nd time.(Windfree subcontracted it out). November 10th - System fails inspection….for the 2nd time. ANOTHER month of generation lost November 21st - We request a discount on the final invoice due to lost solar revenue….no response from Eric, Ashley or Mark at Windfree December 12th - We-Energies schedules their meter installer to be on site with the electrician (Windfree subcontracts it out) December 12th - System passes inspection. December 12th - Home power now on, but basement lights do not work (disconnected in breaker box during the day's work) December 12th - My wife notifies the electrician of this basement issue as he is preparing to leave. He spends more time to correct this problem. Had she not tried the light switch, it may not have been known or fixed. December 13th - Final invoice received from Windfree UPDATE: Eric went the extra mile before, during and after project completion. It was their first time working with We-Energies which made the project more difficult.

Great partners

We found Windfree Solar very easy to work with. Dan Green recognized that we had done our own research, so did not over explain in answering our questions. Jack and the install team are very kind and responsive, checking in every step along the way. The crew that came to do the install let me know exactly what was going on and was cognizant that I was working from home. We feel like we got a good deal and know we got great service.

Going solar in Illinois

After considering various possibilities, we chose Windfree Solar to complete our solar project. They provided clear explanations about rebates, the installation process, and kept us informed about each phase, resulting in the project being completed within the initially communicated timeframe. Since February 2023, my house has operated solely on solar energy, with only comed base delivery charges to pay. I highly recommend Windfree Solar to those interested in adopting solar energy in Illinois.

Solar for the win!!

I got 24 panels installed Feb of 22. Everything went well and dhas been great. Only gribe I have is a chunk of money is still owed to me from the state. I emaill someone from the state every 2 months. Supposedly I am finally getting payment next month, that said it had nothing to do with my installers and more just government being the government. I now have an ev and during the summer months I have had $0 or close to $0 bills. I recommend Windfree Solar to anyone looking for panels very professional and efficient process.

Finished, only after absurd delays

Purchased 14 solar panels, residential. Original install date was pushed back two months because they sat and twiddled their thumbs waiting for licenses from my town, while the town was waiting for info after explaining to them that they needed this. I know this because after weeks of no updates, I went to my town electrical dept and asked what the hold up was, and they explained that they sent and email to WindFree for info and were waiting for a reply. For MONTHS. After install, this happened again, where they sat on their butts for a month waiting for stuff from Aliant Energy, and I'm the one who pinged them asking what the hold up was, and turns out they were waiting for info from WindFree solar. Then once the panels were installed, I couldn't activate them until I got certain stickers safety, which WindFree screwed up repeatedly. AND THEN ONE OF THE PANELS WAS DEFECTIVE, AND I HAD TO NAG THEM FOR A MONTH TO GET IT FIXED, AND THEY ALMOST CHARGED ME FOR IT. tldr: It now works, but I'm convinced I'd still be waiting for those panels if I hadn't done part of their job for them and nagged them for updates.
