"Simply the best around! Sales consultant, install team and post support have been on point, so thank you AES!"

- Paul B., Chico, CA

"All of their workers were very professional and kept me well informed of what they were doing and when. I would highly recommend AES. From the install of the ground mount system to setting the 56 panels — the electricians were very knowledgeable, workmanship was excellent."

- Craig H., Paradise, CA

"Very friendly and professional employees every step of the way. The installers were top notch. They were meticulous in their work and cleaned everything up so thoroughly that if we didn't have solar panels on our house, we wouldn't be able to tell they had even been there!"

- Jason H., Chico, CA

"Brian A. — what can I say, I can not recommend him highly enough! He is so helpful and answers all of your questions without making you feel ignorant!

Great people!"

"My experience with Alternative Energy Systems was great. After researching so many other companies, I am so glad I went with AES☀️😎"

- Uriel M., Gerber, CA

"We just powered up our solar system. I have been very impressed with everyone I had contact with at AES. They were all very knowledgeable, courteous, and professional. During the course of the solar panels installation we dealt with five, or six people who had different roles in the process. I can't say enough about how well they performed their various roles as the process unfolded. Throughout the process there was one person (Elizabeth) who also kept us up-to-date at every step. I would recommend AES with absolutely no reservation whatsoever."

- Dan S., Chico, CA

"I have had a great experience with [AES] from initial contact to installation. I don't do a lot of reviews but I don't think these guys are getting the notice they should be getting. They have a professional setup team, construction team and ongoing service team.

The system looks great on my roof and we have been sending the max to PG&E since day one and our True up is looking real promising. This system is a dream come true. The longer you wait the more your sweat."

- Bruce S., Cottonwood, CA

"The panels seem to be of high quality. [AES's staff] always kept me informed of what was happening."

- Brenda R., Orland, CA

"I had a great experience. I was well informed at every step of the process. This is a well run local business."

- Pat S., Chico, CA

"The warranty and reputation are admirable. All aspects of the transaction were professional, timely, informative and top-notch when it came to customer service by explaining, problem solving, listening to requests and overall communication."

- Joanne V., Chico, CA

"We're so impressed with everyone who worked on our system. What a great company! 5 stars!"

- Lori M., Red Bluff, CA

"AES a truly great provider, very on top of their game. They are really a professional company all the way around. I was pleased with all aspects of their service. LOCAL Company!"

- Ty B., Chico, CA

"Thanks for all your close attention to our inverter issue. Thanks also for sending Kjell to teach us how to reset it if it stops again before a more permanent fix is in place. Kjell was clear, informative and personable. He taught us a lot about our system, and also had some nice things to say about [AES]. We thought about inviting him to dinner but knew he had a life of his own to attend to. Bottom line: we are happy to be associated with the crew of AES."

- Joe L., Chico, CA

"Fantastic communication and quality of job completed. Service in all steps was excellent."

- David C., Chico, CA

"Alternative Energy Systems is perhaps the most efficient and professional business I have ever worked with. From the first visit they were great, answering questions and providing information in an accessible way. Everything they said they would do they did on time and in budget. We are very satisfied with the installation and the product. We highly recommend AES!"

- Laura M., Chico, CA

"We recently worked with AES when they donated over 300 solar modules to our nonprofit, Good Sun. On top of the generous donation, they helped us to load up the equipment, which was a huge time saver for our team. Most of all, the AES team - all the way from upper management to project management, to the crew on the ground - everyone at the company was extremely nice which made the whole experience just awesome. It is clear that this company really cares about the work they do and the people they serve. Really looking forward to working with this great company again soon!"

- Eric Stikes, President and CEO of Good Sun, Grass Valley, CA

"We just wanted to say thank you to you, and everyone who has helped along the way. Everyone throughout every step of this project has been so helpful and so professional. We have been very happy working with your company and have already recommended you guys to our friends who are interested in solar."

- Eric P., Orland, CA

- Vickie B., Chico, CA

"I have nothing but good to say about the service I received AND all the people that I have had dealings with at A.E.S."

- Josh G., Cottonwood, CA

"Initial power generation results are what was projected. We also had a pretty good hail storm the third week the panels were installed and I have not noticed any damage.

From the first meeting to the first power bill every interaction with AES staff was a pleasure. What stood out the most was how good the communication was throughout the process."

- Stephen E., Chico, CA

"Excellent quality, look and warranty. Great expectation management throughout the process and friendly, knowledgeable staff."

- Tyler S., Chico, CA

"AES provides the definition of ideal customer service. From active communication, site visits scheduled around the homeowner, and using every opportunity to provide info/answer questions, they were outstanding. We had tried for weeks to even get basic quotes from other local and national solar providers, all of which either 1) wouldn't call us back, or 2) used evasive sales tactics with no follow through. AES provided the complete opposite of that with clarity, good pricing, and top-of-the line equipment. You will not be disappointed with both your solar equipment and the level of service. I wouldn't even recommend wasting time with others for quotes that will be the same, or higher, for a worse experience."

- Seth G., Red Bluff, CA

"We could not be more pleased with the work you are doing. Thank you."

- David W., Chico, CA

"From the very start of this process AES was amazing to work with. They kept us informed every step of the way. We originally went in just to get information and ended up starting the process. I never felt pressured from the sales rep and felt confident that the information she was giving us was correct not just a sales pitch. The entire staff is very knowledgeable and professional. I will definitely be recommending them to whom ever is looking for solar...thanks again to all the staff at AES!!!"

- Kimberly C., Chico, CA

"Great to work with and always responsive. Only had the system operating for 2 weeks so far, but so far so good!"

- Johnna Q., Chico, CA

“The City Council and staff are pleased to be investing in solar energy to offset a large portion of the necessary power consumption at city facilities. This is good for the city budget, and good for the environment.”

- Peter Carr, Orland City Manager, Orland, CA

"This was an amazing experience from the get go. Our rep, Ian was extremely helpful and just pleasant to be around. He made the process understandable, and smooth. We were kept well informed with every step. I had no idea that getting solar installed could be such an easy process. AES easily has our highest recommendation and we couldn't be happier that we chose them."

- Yvonne R., Red Bluff, CA

"Everyone at AES, the sales, installation and training staff, were all excellent. Highly recommended!"

- Margaret B., Chico, CA

"Excellent communication and service. All staff involved in the process were friendly, helpful, patient and professional. The final product looks great. It was a pleasure to work with all personnel involved and we would recommend them enthusiastically and without any hesitation."

- Brad and Debbie D., Chico, CA

"After almost a year and a half of doing my own solar research and having multiple companies come to my home, AES is by far and away the best here in Northern California. The team at AES is the best in every aspect of the solar process. If you don't have solar on your home, please look into it...I encourage you to shop around like I did. I can guarantee you that once you're finished shopping, AES will beat every competitor with a far more superior product. If anyone needs a referral, tell them I sent you there. You won't be disappointed."

- Christopher S., Chico, CA

"Excellence is hard to attain, AES has done just that. Thank you."

- Norm P., Orland, CA

I think that is a win/win situation. Everything was so easy and hassle free to get going. No issues."

- Carol S., Cottonwood, CA

"We just had our solar system from AES go online and we couldn't be happier. Excellent communication and service. All staff involved in the process were friendly, helpful, patient and professional.

It was a pleasure to work with all personnel involved and we would recommend them enthusiastically and without any hesitation."

- Brad D., Chico, CA

- Luis J., Chico, CA

"I highly recommend AES Team...they are Incredibly through, very fast & efficient, wonderful communication skills with the whole Team. I got five quotes from different companies regarding my high electric bill and AES blows everyone out of the park!!!! KEEP UP THE GREAT WORK AES!!!!"

- Christine S., Orland, CA

"We just installed solar at our home with Alternative Energy Systems and are extremely pleased! From start to finish, the company walked us through the process, answering questions, giving information and showing us how to use our new system. The salesman, Jim, was very helpful with his demonstrations and explanations. The crew installing the system was efficient and courteous. The project manager was on top of everything, making sure things ran smoothly. Kimmie, in the office called every day, asking if we had any questions and pulling everything together. Finally, Abby - who was great - came to our home after everything was installed and walked us through how to monitor the system. Overall we felt that the company did an excellent job of educating us about solar power and how to use it."

- Martha M., Chico, CA

"We recently got our new solar system hooked up and we are looking forward to a long and efficient energy plan. As a businessman I am often times very disappointed in the service level of many companies but in the case of AES I have to say that the service level has been excellent. Every person that I came in contact with including Brian, Chris and crew, Gys, and the very nice ladies in the office, were all very helpful and professional and seemed very content with their jobs. Credit is due to you for having a team with the highest levels of service and professionalism, it shows in each and every team member. I will always recommend AES to friends and associates and I just wanted to let you know that you have a great company."

“I just wanted to send you and everyone a big Thank You for getting my Tesla Wall Charger installed. Really, really appreciate scheduling, permit getting and everything else AES did to get this done for me.

Also, Chad and Kjell did a phenomenal job on the installation They listened to where I wanted the charging station and went out of their way to accommodate my needs. The installation is very clean and professional thanks to their hard work.

AES is very fortunate to have such a great team in the office and in the field. Once again, Thank You so much. Now I’m ready to take delivery of that Tesla P3D!”

- Randy B., Palo Cedro, CA

"We did a lot of research about solar panel construction types by the various manufacturers and after reviewing their track records and warranties we settled on Sun Power panels. Although we are in the Redding area we chose the Sun Power dealer, Alternative Energy Systems, in Chico based on recommendations from friends that have used them.

We cannot say enough positive things about our experience with AES from our initial visit to their show-room in Chico to the final walk-through after our system was up and running. Instead of experiencing a sales pitch when we visited the showroom we had a very informative discussion regarding the various options regarding size, configuration, and benefits. If anything we felt their estimate of "time to pay-off" was very conservative based on PG&E's track record of rate increases. Once we decided to proceed we were contacted by a project manager, who explained the entire installation process and time line. Throughout the installation process she kept us updated and shepherded the paperwork through the county for permitting and PG&E for approval. She also set up convenient times for the work crews to install the panels and all electrical connections to our main service panel. The crews that did the work were fantastic; they were prompt and courteous and their work was top notch. I was truly impressed with their attention to detail; something that I have not seen with other company's installs that we looked at. Once the installation was complete AES had a "solar coach" come to our house to explain how to monitor our system in terms of energy production and how to monitor our PG&E account including a discussion of how PG&E's net metering and annual "true-up" process worked. Bottom line AES has great folks that do fantastic work."

- Don K., Redding, CA

"We reached out to a few different companies at the beginning of our solar journey and couldn't have been more impressed. SunPower has the most efficient panels on the market and AES has the best service in the industry.

We had a tremendous experience from the initial consultation, through install and all the way through the final solar coaching meeting. We are saving money, doing the right thing, treated wonderfully by AES and have the best hardware on the market - I don't know how we could ask for more.

Highly recommended!"

- Ben K., Chico, CA

"We want to thank you and the entire SunPower and Alternative Energy Systems Team for all that you did for us, as we changed to your remarkable solar system. Every single one of you did outstanding work, and your customer service is the very best! It has been a pleasure to work with you."

- Denise and Mike O., Chico, CA

"Good quality panels and a good [warranty]. AES was good at communicating with us, were professional, did a quality job and continued to communicate and educate us after the job was done."

- Dominique T., Gridley, CA

"Panels are look too be good high quality hardware, Looks nice and has a minimally noticeable setup once completed. Have seen my employer's home install as well as a large system installed at our company prior to having them do my house. Have already recommended them to my mom."

- Greg and Heather K., Chico, CA

"Good, friendly people to work with. All their employees were courteous and respectful."

- Randy and Sheryl C., Chico, CA

"Every [AES] employee I came in contact with (eight) would be considered a "standout" in most other businesses. They always did what they said they were going to do, did it when they said [they would] and whenever they did not do it the way I would, they did me one better."

- Charles T., Los Molinos, CA

"We are so happy we chose Alternative Energy.. We received three other bids and tried to deal with different companies and found out about hidden fees not revealed, false promises, etc.. This company was so honest, professional and top notch. I recommended them to my neighbor who just installed their panels too. Great service, homeowner training and best on the market panels..."

- Debbie L., Redding, CA

"Thanks again for all your help…you all have been fantastic with your communication and follow-up, and I do mean all of you. It has been a pleasure working with a company like yours…very rare in my opinion, so thank you!"

- Andy B., Chico, CA

"We are impressed and pleased with the product and service provided by AES. They surpassed my expectations in all aspects from start to finish. The company was in constant communication in regards to timelines and updates on the installation process -which I appreciated. I even was pleased with the follow-up appointment after our solar was up and running to ensure I had all pertinent paperwork and understood how to monitor our system.

The employees were an absolute pleasure to work with from the initial consultation, through installation and set-up, to follow-up. Zayd and Isaac, the installers of the panels, are my heroes! During installation the neighbor dog knocked out a fence board and was aggressively ready to charge my granddaughter and me. As I was holding the fence board Zayd quickly rushed off the roof and screwed the fence board back into place! He did not hesitate to come to our rescue. Before returning to work Zayd and Isaac made sure my 1 year old granddaughter and I were OK and calm. They put "people before task." AES hires quality and professional people."

- Helen G., Yuba City, CA

"Jim and Kimmie who helped me, were extremely knowledgeable on their process and were very easy to contact. Of all the contractors that I have ever worked with, the [AES] team is the best experience that I have had."

- Michael & Sandy C., Chico, CA

Everyone from our initial sales person to our solar coach was outstanding and very flexible in meeting our needs and time table. Your program goes beyond what we found from other solar providers.

- Bill & Laura H., Marysville, CA

The quality and warranty appears to be more substantial than what other companies are currently offering. The installation was quick and hassle free.

- Sabrina S. & Jody B., Anderson, CA

Felt like family members working on our project. Professional and respectful. Excellent experience and always kept us informed about details throughout the process.

- Kevin & Robin B., Anderson, CA

We are so impressed with SunPower panels. They are top quality in every way. The panels are superior in their construction (nearly indestructible under normal conditions) and the amount of solar energy produced per panel is far more than most companies can claim.

Alternative Energy Systems guided us through the installation, permit and user info process seamlessly. They are very knowledgeable, professional and easy to reach. Every call was returned promptly and every concern alleviated.

Our installers were great! They worked right through the rain and then came back when the ground dried up to smooth everything out. The electricians were tireless in their effort to make sure the cables were out of sight. They also showed great care of protecting our property throughout the install.

We highly recommend this company and system to anyone looking to go solar.”

- Lynda F., Redding, CA

Dear AES team, thank you so much for the very generous referral [check] - we couldn't be happier with our system - we will be working on our neighbors to get on board.

- Bob and Kathy R., Chico, CA

"It took me three years to find a solar company that I felt comfortable with, which included passing on a good friend who is in the solar industry. When I finally pulled the trigger it was with SunPower by Alternative Energy Systems in Chico (yes, their name IS too long). I am that PIA customer that all salespersons dread. However, Chad took that in stride and was extremely patient and understanding with all my questions and concerns. He was so easygoing and low key I'm not rightly sure he can be called a salesman but salesman he is and a damn fine one at that.

If I thought that professionalism and friendliness would evaporate, once the contract was signed, I was sorely disappointed. The installation crew and electricians exemplified the highest standards of their profession. Not only were they punctual, efficient and quick, but they also cleaned my gutters and helped my wife charge her car battery. My only regret was not having a longer list of chores for them.

Because of the construction of my home (log cabin) I didn't want to ruin the aesthetics with a bunch of conduit, junction boxes and other unpleasantness associated with typical solar installation. Not a problem. The boys ran everything through attics and duct chases like little sneaky little ninjas! I don't think the bats or mice even noticed. If there weren't solar panels on the roof you'd never know anything happened and that included wiring in a backup generator.

I'd continue gushing with this review but I need to go outside and admire my glorious new solar array while mocking the PG&E trucks driving by."

- Sam C., Oroville, CA

"We were very pleased with the team at SunPower throughout the process. From the initial consultation to the final walk through, the entire process was easy and professional. They were incredibly fast with their install too as it allowed us to receive our tax credit on this year's instead of needing to wait until next year."

- Jody B., Anderson, CA

"Definite savings in my PGE bill. They enabled me to secure funding for the project. The sales and installation staff were professional, courteous, and competent. Not being an engineer, I could benefit by more in-depth knowledge regarding how to understand the system's operation and displays. Overall, this project gets top marks."

- Dana V., Yuba City, CA

"AES just finished installing our SunPower panels and we heartily recommend them to anyone thinking about solar panels on their home. They were professional and knowledgeable throughout the process and all their staff were courteous and great to work with. We especially like the software that allows us to monitor the performance of the panels on our smartphone and computer. Props to AES!"

- Lee H., Chico, CA

"AES did a fantastic pro job from start to finish. They have knowledge of the SunPower duct and know what they are doing. They have the same type of business ethics as SunPower. They strive to be better and are never satisfied with just being good."

"Good follow through - Brian helped with completion of all forms. [The panels are] functioning well. Looks nice on barn roof. I like the usage app and website to track power.”

- Bob M., Orland, CA

“Your Team kept me fully informed of each step during the entire process. Appointments were kept or updated as needed for both initial survey, and the two phases of installation. The roof mounting, along with roof penetrations was expertly done and very clean. We have had two heavy rain storms since finishing the project and there have been no roof leaks or any other problems associated with the installation. The electricians were well qualified and performance quality of installation was outstanding. The finished product is a fine example of proper installation of conduit, distribution panel, and monitoring equipment. Electricians were very friendly, explaining each step during installation and cleaned up their work area at the end of each day. Would highly recommend your product and crew to anyone considering a solar system.”

- Stan H., Oroville, CA

"From the first consult to the completed install, it’s gone great. Their team, run by Mischa (PM), Elizabeth (Project Coordinator) and the installers (Carlos, David, Mike and Justin) have done a fantastic job on communication of status, upcoming items, clean installation (detailed, hard workers) etc... I am extremely happy that we went with them on this install.”

- Bill J., Magalia, CA
