Awesome Company!!!
Great company to work with. Very detailed and clean while working as well as the installation. Spencer and Jessie were awesome and helpful during the process and the system is working great! Would highly recommend ECG if you are looking for a solar install.

Battery complement to Solar system
I recently had ECG Solar add a battery system to my existing solar setup, and I couldn't be more pleased with the experience. From start to finish, they demonstrated an impressive level of expertise—not just with the new battery system, but also with my existing solar array. They took complete ownership of the project, ensuring that everything was integrated seamlessly and delivered the expected outcome. ECG Solar stood out for their unwavering support, guiding me through the process from my initial analysis all the way to post-installation follow-up. Their commitment to making sure my system performed as expected was evident every step of the way. In an industry where companies come and go, ECG Solar is a reassuring presence—professional, knowledgeable, and stable. Their ability to work with a broad range of reputable brands further highlights their expertise. If you're looking for a solar and energy company you can trust, I highly recommend ECG Solar.

Awesome System ECG is the best!
I cannot thank ECG Solar enough for everything they did for my family. I originally contracted with Moxie Solar to install my solar system. They went out of business and took my family's money with them. I called up the local news station and told them my story which was featured on I-9 investigates. ECG Solar saw the story, called me up, and offered to install a solar system on my home for free. I was taken aback as I have never experienced kindness, or compassion from a business in the past. Not only did they install everything free of charge they managed to get all of the equipment free of charge for my installation. The solar system has significantly reduced my electricity bill and is extremely reliable. The team is extremely professional. They show up when they say they are going to be there, clean up after themselves, and treat your property with respect. Deciding to make a financial investment this big is already a huge decision. Please take it from me and give ECG Solar a chance to win your business. You will receive a quality product from a quality team that stands behind their work. These two things are rare in this industry. Let them guide you through the process you will not regret your choice!

ECG was professional, competent, and thorough
I began to research solar energy about 5 years ago. I checked out solar brand panels and solar installation companies. As a result, ECG carried the brand of panels I hoped to have installed, and ECG had many excellent reviews, so we selected ECG. We have no regrets. First of all, there was no hard sell, but their approach was to provide us with information. From the beginning of the process to the end, communication was ongoing and excellent. The electricians did an excellent job and worked efficiently and tried to save us money in the process. Every step of the way went well and was well timed. Our solar array is producing electricity and we are totally pleased with the final result. We would recommend ECG highly and have let friend know about this ECG.
John R | Cedar Rapids, IA | 04/16/2023
ECG Solar installed our system in the Fall of 2022. They were very professional, installation of panels and electrical system updates were performed over 3 days. ESG coordinated all of the paperwork - particularly the coordination with local utilities. System is performing as advertised and we are enjoying our reduced electrical bills.
Bruce Barton | Riverside, IA | 04/03/2023
Very good company
We did a twelve panel installation on our home. Everything went well and according to plan. All the technicians were great people to work with. Our system is working well. I highly recommend ECG Solar!
D. Butler | Waterloo, IA | 01/10/2023
Easy to work with Great service!
ECG is a great company to work with for your solar needs. This was a major purchase for us and the proposal that was given to us had all sorts of great information that helped me make the decision to move ahead with the project. ECG made this a turn key operation and answered any questions i had which was really nice. Plus they are a local business offering top of the line products and excellent service. I make sure to let people know who installed my system
Scott B | Bettendorf, IA | 12/12/2022
Highly recommend
Entire experience with ECG was top notch. They took the time to explain the entire project and how/what would take place, and they were exact on target. I had several other companies give quotes and presentations that thankfully I ignored as they were not honest in the expectations. If/when I add onto my system with batteries I’ll definitely contact ECG to do the work. Best workers in the office and the field.

Excellent installers, quick service, and helpful staff!
ECG did a fantastic job of the install. I'm producing wonderfully clean power and I couldn't be happier with the team and their patience with all of our questions. If you're going to get solar installed - go with ECG!
Nick Becker | Cedar Rapids, IA | 05/19/2022
Disclaimer: ECG incentivized me to leave this review, but I've done my best to keep my review accurate and honest. My solar system was installed on June 14th, 2021 and (finally) powered on July 17th, 2021 after being approved by Alliant. ECG did a great job throughout the entire process. They adequately sized my system based on my needs, and the panels have effectively eliminated my electricity bill (minus monthly service fees) over the past year. Prior to installation, they provided an extremely detailed report with information about the expected performance, utility savings over time, expected ROI, and environmental impact. I've attached some pictures showing the end result at my home. ECG subcontracted a lot of the electrical work, but I thought they did a great job making the conduit not stand out too much. Initially I wasn't too happy about how they routed the conduit up and over the roof, but I rarely notice this anymore. They also removed a large chunk of drywall to run some of the conduit into my breaker. It would have been nice if they patched this up afterwards. One minor complaint is that the estimated utility savings in the report provided by ECG assumed that the power company had a policy of "net metering", but Alliant switched to an "inflow-outflow" tariff for systems (like mine) that were connected after December 30th, 2020. In particular, the inflow-outflow tariff does not include a "True-Up" payment to reconcile net-meter credits accumulated during the year, which was assumed in ECG's analysis. So currently I don't have a solid understanding of how much money I'm actually saving, but I assume it is comparable to what ECG estimated I'd be saving under net metering. It was disappointing how long it took to actually turn on the panels after they were installed, but this was no fault of ECG, and I was warned of this ahead of time. After the panels were running, I discovered that Enphase offered some optional hardware to enable consumption monitoring. I reached out to ECG and they were able to install this optional feature within a week or two. It makes it much easier to see how much energy I'm using and producing, and also makes it easier to verify that Alliant is billing me correctly. Overall, I'm very pleased with my experience with ECG and would recommend them to anyone interested in solar. I will definitely be reaching out to them in the near future when I decide it's time to add batteries to my setup.

Great Company
Nothing but good things to say about ECG. From first visit with Steve to finding out what hardware we needed to pricing (which was exactly what was quoted) to installation to start up everything went smoothly. The APP is a lot of fun and super easy to use to see what your production is. I would recommend ECG to everyone.
Jeremy Kunz | Mount Vernon, IA | 05/15/2022
2nd project
This has been our second project with ECG Solar. We could not be more happy with the results and the quality of the workmanship and the project. Our system has kept pace with our uses and our electric bills have been the mini-immune charge all winter. They helped with all of the rebate information and all of the set up. Excellent staff and local contractors. My wife and I highly recommend them.
Steve | Cedar Rapids, IA | 05/15/2022
Very good experience with ECG Solar. My site was not ideal but Jason explained everything, gave me the data to evaluate the viability and I am very pleased with the results. Andrew and the crew from A&H Electric were awesome. I highly recommend ECG Solar for both solar panels an Kohler standby generators.
Tammy M | Marion, IA | 05/05/2022
Great company to work with
This was a great company to work with. They under promised and over delivered on the electrical output. Compared to the other companies that came out ECG was more knowledgeable compared to other companies for the questions we had. You will still have Fees on you electric bill that you will need to pay, Even when the electric company buys back from us. Many people ask about that so I want to make sure people are aware that you will still have fees. In the middle of summer when running the AC Our electric bills was less than $10.00 because of the fees.
Kevin JJ | Waverly, IA | 05/03/2022
ECG took care of most everything for the installation. Excellent communications throughout the process. I have not had any issues in the 10 months it's been operating. The net-metering system has been able to keep up with my electric power usage even over the winter months. I would recommend ECG solar.
Hart | Marion, IA | 05/03/2022
Extremely Professional
Below is the review I left on Google so I won't repeat it all, but these guys were great. They held my hand from beginning to end and even after it was all wrapped up. I haven't dealt with other solar installation companies, but it would be hard to imagine someone doing a more thorough, professional job. Google Review: ECG Solar was passionate about their product, extremely knowledgeable about the process and industry and their professionalism throughout the entire process was very, very impressive. From answering pre-sales questions, to scheduling, and even following up with tax deduction documentation after the project was complete, ECG was buttoned up throughout the whole process. Can't recommend them enough!
Clay G | Cascade, IA | 05/03/2022
Extremely Satisfied
Installation was smooth. The system performs exactly as promised. The savings and benefits grow each month.
Nathan G | Iowa City, IA | 05/03/2022
Great experience start to finish
The team at ECG walked us through the process, explaining details and answering questions as we went. They took care of the paperwork with the electric company, and did the install with minimal disruption. Within about a year, one panel stopped working, and ECG took care of the RMA and install of the replacement panel under warranty at no cost to us.
Wayne F | Marion, IA | 04/29/2022
Great experience and value
ECG Solar was great to work with. They quickly responded to my inquiry with detailed information and site evaluation, making sure that we understood all that was involved. The installation went smoothly and quickly. The crew was efficient, answered my questions and left the worksite clean. This is one of the best investments we have made. Our electric bills have been extremely low over the first winter.
Dan C | Marion, IA | 04/26/2022
Jason and his team were great to work with. Made the process very smooth.
Derek | Cedar Rapids, IA | 04/23/2022
Great company with great product
ECG recently installed solar panels for a my house. They worked around my schedule and managed the project very well, including answering all of my questions promptly. The solar system has been operational since last fall (2021) and has been great. Monitoring the amount of power generated is intuitive and it has become clear that ECG was able to calculate a system size that is perfect for me. The system is not too large or too small.
Lincoln R. | Cedar Falls, IA | 04/22/2022
I would highly recommend. East to work with and do a great job.
Roy H | Marion, IA | 09/15/2021
Professional, quality installation of our solar electric system
Very happy with our Solar Electric installed by ECG. Owner is passionate about quality and meeting standards and that showed throughout the process. ECG was not the least expensive of the proposals we received, in fact they were the highest cost, but, we had a relatively painless installation and commissioning of the system. One little hiccup when trying to commission the system, found connections not made right during installation, but it was fixed that same day and producing power. Must be patient with this process regardless of vendor, have to get through utility and local inspectors, it took a little over 3 months from start to finish for us. ECG's installation was one day, electrical was one day and then commissioning the system was another day. Most of the rest of the time was waiting for paperwork and approval from utility and some likely waiting for equipment and ECG's workflow. Do some research ahead to have an idea of what panels and systems are available but be open to input during proposals too. The owner provided us a good education and made a great presentation. Any questions were answered quickly, don't be afraid to ask questions, I waited on some and shouldn't have. ECG has a strong local presence and a passion for quality from the owner to the installers and we felt those we important qualities.

ECG made my dream of Solar Energy a reality!
I prefer to do things "in person". It gives me a sense of who I am doing business with. ECG was prompt and professional. Their products are superior, and they are quick to respond if you have a question or concern.

Energy Consultants Group performed a timely solar system install
ECG was the low bidder on our solar system installation.
Casey Simpson | Des Moines, IA | 02/24/2021
Excellent company takes the time to understand and give options
worked with ECG to complete 2 separate solar panel installs at my home. Sales rep (Steve) was incredibly responsive, answered all my questions, changed the bid easily a dozen times to make it work into my financial goals, worked with multiple finance providers to get me the best deal for my requirements (monthly payments less than what I'm saving in electric.). Steve did an excellent job in producing a full incredibly detailed forecast report on solar production to expect, and monthly electric savings. Jason did a great job in looking at the construction layout of my perlin-frame garage to make the panels use the maximum amount of roof space available. Installers were incredibly fast, got the entire array installed and up and running within a week (3 days initial phase, then about 1.5 days for the additional array on the back). The solar arrays have been in operation for nearly 5 months now and so far my actual production is beating Steves projections by about 15-20%, so producing even more than what they forecast. He did say their projection tool was on the very conservative side so not to over promise actual results and so far that appears to be accurate. Very pleased with the whole process. Cant forget mentioning Paula in this whole process also, getting all the paperwork submitted, installation crews lined up, scheduling electric company for tie-in, permits, filling out the tax rebate paperwork. The whole group was a charm to work with, and my electric bill has gone from $700/month average to less than $50 the last 2 months.
Doran Williams | Riverside, IA | 10/30/2020
New install
We were referred by a friend that had an array built on their house roof. We had a ground array set and and are very happy with it. High quality equipment and professionally installed. The system is very well built and is working great so far. We just got set up and can monitor everything that is being produced.
Michael | 10/21/2020
Great company, quality workmanship
Jason did a great job on our project, was responsive to all inquiries and very professional. I feel I got the best product available installed by the best installers.
Anthony | 10/21/2020
1 year in - very happy
In 2019, as the solar tax credit was about to start its slow march towards expiration, I decided I should look into solar power. I hadn't done as much research as I probably should have and had tons of questions for our first meeting. They stopped out and provided a ton of insights into the process, documented long term pay back, how the loan would work to effectively keep my monthly electric bill on par with what it was prior to the solar install. Note that Iowa has a lot of unique rules and regulations, and that your local power company also may have many rules and regulations and hoops to jump through. The most work I ever did was answer questions, sign some papers, and pay my monthly bill. No up front costs, no dealing with permits, no dealing with the power company. They took me through the whole process (I think Paula gets most of the credit outside of the install!)

Great results from ECG!
We had a great experience with the Energy Consultants Group team when we had our panels installed. They were on time, quick, and very thorough. If you are looking for a Solar installer, you'll find no better team in Iowa!
Clive, IA | 05/11/2020
Premier Solar Installer
Living in Clive, IA, I spent a fair amount of time researching solar companies. The team at Energy Consultants Group is the one to turn to for any of your solar projects. They are well versed in the latest technology and ways to optimize your project for the best solar gain. The service was excellent from design, permits, installation, and tax forms. They kept me informed at all levels and continue regular follow up on the installed product.
PwdbySun | 04/21/2020
Great to work with: communication and professionalism.
Entire process went very smoothly. Communication was great at all stages. Held to original cost even though our installation needed an extra component and effort. Staff answered all questions and explained installation and system operation.

Spectacular to work with
Jason and the crew at ECG were fantastic to work with. They were knowledgeable, professional and timely in the work they performed and were able to answer any and all questions I had. In fact, Jason made a personal visit to my house to answer questions and help me move my hub from where it was installed to a more centralized location of my choosing. I recommend them if you are considering going solar. Ben C.

We contacted four companies and only two responded. Energy Consultants Group, LLC was the only respondent that gave us a detailed cost analysis at the first meeting and looked over the project site with a certified electrician.

A group of friendly folks installing my solar system.
I choose these folks for the positive comments I had heard from others about this company and the quality of products and work they perform. My son was also a customer of there's and he also was very please with the outcome of the system installed and the folks he also worked with at Energy Consultants Group, LLC.

This was a large installation and it was determined special mounting brackets were required. Jason was able to find a source for them. We had a lot more rain this summer than usual and the crew came out and worked hard on a day when rain was predicted by the weather bureau, but they got most of the mounting in place. We had a nice day later and the panels were installed. This was all hard physical effort. The electricians they contracted did an excellent job. We spent some time discussing the panel board and they installed it so a transfer switch for a backup generator could be added in the future. I probably asked more questions than most customers, and they patiently answered them. The system has been running for a week and all is well. I would recommend Energy Consultants Group to anyone in the area they serve.
P Whitman | Lisbon , IA | 08/02/2019

Residential install in Marion
ECG provided an incredibly detailed proposal for a plan which covers 99% of our total electrical needs. Their service was perfect and the installation went smoothly. The city inspection did not yield any required followup. All in all, we are incredibly satisfied.
Jason B. | Marion, IA | 07/30/2019
Great experience working with ECG!
ECG was a pleasure to work with! They provided us with a very detailed initial proposal within a few hours of contacting them. After speaking with them further, they provided a revised proposal with some changed we asked for. They answered all of our questions completely and accurately. Our installation was well planned, well installed and looks great!
Marion IA Residential ACPV Proje | Marion, IA | 05/11/2019
Marion IA Installation
Energy Consultants Group (ECG) provided the most comprehensive proposal, which outlined the use of high-quality LG panels and Enphase balance of system hardware. In sum, it was the superior proposal of all we received. Regarding our project, Working with ECG was exceptionally efficient. All work was completed within the agreed to scope and price. We are happy with the quality of the LG solar modules, the Enphase micro-inverters and Envoy control panel. The overall installation of the solar modules, supporting rack system, and electrical work was completed in a timely, competent workmanship manner. City electrical inspection and Alliant Energy approvals were attained without impediment - all managed by ECG. Since we are in the early phase of energy production, we have every reason to anticipate any potential support needs will be met with a high degree of responsiveness by ECG, consistent with our experience with our installation project.
