Best value among highly rated competitors ⭐️ ⭐️ ⭐️ ⭐️ ⭐️

I am absolutely thrilled with the exceptional service provided by Complete Energy Solutions! From start to finish, their team demonstrated unparalleled professionalism and expertise in installing our solar power system. First and foremost, the design process was outstanding. The engineers at Complete Energy Solutions took the time to understand our specific needs and created a customized solar solution that maximizes efficiency and savings. Their design standards ultimately outweighed cost in our consideration of contractors among the very highest rated companies on We chose Complete Energy Solutions as the best value over the lowest cost. The quality of the components used is top-notch. It's clear that Complete Energy Solutions prioritizes using the best materials available, ensuring long-term reliability and performance. Our new solar panels are not only highly efficient but also aesthetically pleasing, seamlessly blending with our home's architecture. Communication was another area where Complete Energy Solutions excelled. Throughout the entire project, they kept us informed and updated, promptly addressing any questions or concerns we had. Their transparency and willingness to go the extra mile made the entire experience smooth and stress-free. Matt spent the inspection day waiting and then escorting both the electrical and construction inspectors through the project. This ensured a single inspection was sufficient!

I highly recommend this Colorado-based, Veteran-owned company to anyone considering solar power – you won't be disappointed!

Craig Fisher, president of fisher auto in Boulder

I hired Complete Energy Solutions to install a 18.86kW system comprised of 46- Silfab 410BG solar modules, and 3-SMA inverters, on my personal home, I had two other local people turn down my home due to complicated roof design, but Complete Energy Solutions figured it out and did a tremendous job on my home. The owners, Matt and Jennifer and their team have the technical know how regarding product, permitting & installation. I am also having complete energy install an approximately 1600 panel system on our dealership in Boulder, I have a complete trust in them and I’m totally satisfied .

I am writing to recommend Complete Energy Solutions to anyone considering installing solar panels on their home. I had a wonderful experience working with them, from the initial consultation to the final installation. The first thing that impressed me about Complete Energy Solutions was their knowledge and expertise. The owners, Matt & Jennifer, took the time to understand our needs and goals, and explained the solar process in detail. They also answered all of our questions patiently and honestly. I was also impressed with the quality of the solar panels and installation. Complete Energy Solutions uses high-quality components that are NOT made in China, and their installers are experienced and professional. The installation process was quick and efficient, and the panels were installed neatly and securely. Since the installation, I have been very happy with my solar panels. They have generated more electricity than I expected, and I have already started to see a HUGE reduction in my electric bill. I am also proud to know that I am doing my part to reduce my carbon footprint. Overall, I am very satisfied with Complete Energy Solutions. They are a family company that I would recommend to anyone looking to install solar panels on their home. If you are considering installing solar panels, I highly recommend Complete Energy Solutions. They are a family owned and operated reputable company that provides a high-quality product and service.

Outstanding and Practical Knowledge and Service

Our original solar pv panel and inverter installation was in 2011 from Complete Energy Solutions (a.k.a. Denver Solar at the time). For 12 consecutive years, we've had a reliable and trouble-free system. We recently upgraded the panels and inverter, and are glad we chose Matt and Jennifer and their team once again. The quality of the design, which includes reducing points of potential failure, is top notch. Matt, Jennifer, and the Complete team are a pleasure to work with! Highly recommended!

Best Solar in Colorado

We purchased a solar system from Jennifer and Matt, and their company is excellent. They are small enough to give personalized support, and yet they also work big, commercial projects, so they know what they're doing and can offer solutions customized to your needs. They are available for questions and concerns and treat you like family. The experience working with Complete Energy Solutions was the best contractor situation we've had with our home, and we've used quite a few over the years. My in-laws used a different Denver-area solar provider at the same time and had a rough experience, so I know Complete Energy Solutions stands out as an excellent provider in the Denver area. I went with Complete Energy Solutions based on their online reviews, and I am not disappointed. They deliver and are worth your time and money.

Wonderful! Local! Home-Grown

It’s a big move when an older couple puts its trust and considerable capital into as big an investment as solar panels! It also comes with loads of research and pondering when choosing a company to make that dream come true. Enter Complete Energy Solutions LLC! Knowing it would be a big outlay of cash, we agreed to research online sites like Solar Reviews, the BBB and Energy Sage for reviews. With several others, Complete Energy Systems emerged with an “elite” rating so they “made the cut” to our short list of possibilities. Additionally, we asked friends who had solar panels or knowledge about the industry for recommendations and some good acquaintances recommended Complete Energy Systems. Here’s what we found: where other very well rated companies didn’t even return our calls, Jennifer Morrison, co-owner of Complete Energy Systems was immediately responsive and very forthcoming with information and patiently answered our questions. We learned CES is a twenty year old local firm, based in Arvada, CO and the definition of a family business. It’s owned and run by Jennifer and her husband, the very professional and competent Matt Morrison. We were also attracted to the “genuine” feeling of this firm and contracted with them in early September. Jennifer visited or was available by phone many times before the real installation. They took our suggestions seriously, obtained the necessary permits. The installation went smoothly thanks to the work and expertise of Matt and Jennifer as well as their team which included members of their family (their actual offspring). This is the definition of an American family business. The installation took place in October where here in Conifer with its unpredictable weather but they forged ahead with what seems to be a very good job with quality components. The system has been up and running for about two weeks and so far we’re very pleased. The few times we’ve phoned with questions, they’ve been very forthcoming.

Just a really good company

I had had others come look at my home as I had very specific needs. Jennifer and Matt came and said no problems,, identified the specific things they needed to meet those specificities a reality. It was not the wait for install that I had expected. There were some post install issues. No idea as to where the problem was, since multiple projects at the same time. They came out, identified the problem, which was not theirs, so the repair could be done. They are available to all my questions. I have found that winter is not the time to install the solar panels to see great sales to the grid, but know in the sunny months it will be gangbusters. I am so impressed with their kindness, expertise and professionalism. The knowledge base for both of them is far reaching. They have my absolute trust and respect. Thank you!

Amazingly responsive

Generally, I am skeptical of all contactors based on their sales techniques and performance. However, this company is absolutely the exception. In fact, I wish that all contractors were as attentive as this company. We first contacted them over one year ago and learned what we needed. However, we weren't quite ready to pull the trigger. A year later, they had all of our information and were able to schedule us right away. They outlined the specific steps in the process, provided realistic timeframes and performed as promised. Every step of the process was met with high energy, competence and attention to detail. This was true from the engineer, the production manager and every employee. They have a wonderful team. In the end, we are not only satisfied with the work performed but have also referred them to others. I am proud to have them on our side AND on a side note, I feel like I can call them my friends. It is not often that you fall into a groove with a person/team. They have such a genuine approach to fulfilling expectations. And at the same time, willing to share their personality with you.

The BEST Solar Company that won't cheat you

I spent 2 years researching solar companies and doing my due diligence with regard to whether I'd need them or not. Given that Colorado—demographically—produces the most sunshine with less atmosphere and that they were shutting down the coal plant near our home, it seemed a no brainer. The rest of the companies we looked at were... sketchy at best. Jenn and Matt (the owners) are both veterans and straight shooters. They do NOT finance, but only do install and were able to explain everything in layman's terms. They were able to compare other bids and point out the issues. We've had our system now for a month and have no electric bill and actually rolls over onto the grid to save us money in the winter months. Point being, is that you shouldn't waste your time on other companies. I researched them all for you already, and Complete Energy Solutions/DenSolar is, hands down, the best!
