CleanTech Energy Solutions Inc.

Since I have benefitted several times from NextDoor neighbors' advice, I'd like to return the value. I had a serious repair problem with my large 11 yr old solar system. The inverter failed! For the month of May I was not generating any electric for my home or back to the grid. Fortunately the SolarEdge inverter was still under warranty. I contacted CleanTech Energy Solutions. They responded within minutes and scheduled an installation diagnostic appointment for the next day. The following day they did the install. The work was superb and very fairly priced. The "handholding" they provided for registering the new system was simple and complete. I'm now going to work with them for a battery backup system. I could not have asked for a better experience. Thank you Karin & Keith.

CleanTech was phenomenal to work with - one of the most responsive and accommodating contractors I have ever used.

Stop looking, Clean Tech is the answer to all your solar needs. They actually do what they say they will do! Our Solar journey started in April 2023 with an dishonest solar company. They went bankrupt and left us high and dry with equipment and panels up but not connected and NO permits - a nightmare! For over a year we looked to find someone to take on our project and got a "no" after "no", nobody wanted to help us. I was about to give up when I checked SDGE website, looked for approved Solar installers and found CLEAN TECH ENERGY SOLUTIONS. We set up an appointment and met Keith and Karin, owners operators. From the first meeting they inspired confidence and honesty. Honestly they were a true blessing to find such honest people in a world full on unscrupulous contractors. Keith and Karin explained things in easy to understand language, they are extremely knowledgeable, very easy to work with, honest and upfront. Karin was attentive and responded quickly via text or email to my questions or concerns. I can't say enough about them - Thank you so much!

We are very happy with our solar system and the customer service is truly outstanding. All of our questions were answered, and we received a detailed notebook including all warranty and necessary information. Our friends even received a referral bonus!

As a person who retired from 43 plus years in the construction industry I am intimately familiar with the process of vetting potential contractors and reviewing contracts for work on projects that demand quality, reliability and responsiveness. I spent several months of research in preparation for our Solar Energy project which included some very big names and some very old established companies. Of course just because they are old and established does not mean that they have been performing Solar installations for all of the stated years as it is still somewhat of a newer industry which runs contrary to what some of those commercials imply as one will encounter on the television commercials. My research included interviews with folks in my neighborhood with prior Solar Energy installs as well as online research. I always include The Better Business Bureau in my personal research as well as the California State Contractors Licensing Board. I prepared a spreadsheet where I could compare each companies offers, working to get each to an apples-to-apples look as much as possible. I also researched the products that they were proposing, especially the rooftop tile installation mechanisms. But perhaps the most telling and the most critical revelation was when I asked for prior references. That is were CleanTech Home Energy Solutions absolutely blew away everyone else. Nobody else touched the positive feedback and the number of responses I was able to contact and converse with. I was really taken aback by the lack of references to contact especially from that one much older establishment who advertises so much on television. Oh, and CleanTech was the only company of my selections who came to the home to review the site conditions including the current grounding situation prior to completing their proposal. That's a sign of a truly professional company speaking as someone who has visited 100's of sites for site inspections throughout San Diego County during my career. As I noted one of the things I was concerned with was the roof mounting system for our Spanish style concrete tiles. They have it right and it's the same products used by the bigger companies. NO LEAKS, no drilling through tiles. And the work performed by CleanTech Home Energy Systems is flawless and professional in the greatest sense using REC panels and SolarEdge products for my installation. which was my preference. Down the road, if we are still at this home I will be looking to CleanTech Home Energy for the battery backup supply and installation. The SolarEdge unit I had them install in the garage is already "battery ready". It is also EV charger ready if you are ready to go that route. So I hope you have read through the length of this (sorry), but I can't say enough good about CleanTech. They are the way to go. Don't hesitate to vet them and ask for references. I truly think you will want them installing your Solar system as well. And let's not forget that wonderful Federal Tax Credit to be realized.

We are very happy with the entire process of buying solar for our home from Karin. She's incredibly knowledgable, has been in the industry for years, and is a local vendor. She's very honest, answered all our questions, sells a great product, and it was a delight to meet Keith and the rest of the crew. They let us know when they were coming, always showed up, cleaned up after the work. We installed 22 panels, and in the future we'll have them add a battery wall. I hope my review gives you the confidence to purchase from CleanTech for your business or residential installation. Overall our experience was wonderful!

My old solar hot water storage tank finally gave out. Clean Tech was able to find a replacement tank to match and they installed it quickly and brought our solar hot water system back to life. I am very impressed with their knowledge of my old system installed by others years ago. Clean Tech will be my servicer.

I strongly recommend CleanTech. CleanTech guided us through a complicated water heater problem - where both the manufacturer and the installer (from a different company) wanted to avoid resolving the issue. We thought our recently installed and badly leaking water heater had to be replaced, but Pablo from CleanTech fixed all the manufacturing and installation problems saving us thousands of dollars. Karin from CleanTech watched over us and always had a plan b or c - a very comforting situation. We had to call CleanTech again because of yet another problem caused by another company. Pablo returned, fixed the problem and spent the time to go over the system with us.

We chose Clean Tech because they were highly recommended by another client and upon meeting Karin and Keith, it became clear very quickly that they were knowledgeable and would be a pleasure to work with.

CleanTech took care of installing our solar and they made it a pain free process. Karen was professional and took the time to explain each step of the process. The technicians who came out to the house showed up when they said they would and they were very nice and took extra care installing all of the equipment. I would recommend Cleantech for anybody looking to go solar.

From the time I called for a estimate until the solar was turned on, The service was top notch. Finally a contractor who shows up when they say they will. As well as the price was MUCH cheaper then others for the exact same system as well as installed sooner then others could.

The people from CleanTech were informative and answered all my questions and also made things simple by describing them in plain english without overwhelming me with too many complicated details. They were also helpful in dealing with SDG&E and County offices.

Karin was a pleasure to work with throughout. The installers were very professional and courteous. CleanTech worked well with the roofers. The installers painted the conduit lines to match my roof and walls. The SolaRay System consisted of two 3ft x 8ft Solar Hot Water Collectors and one 80 gallon HX Solar Tank. This system used my gas hot water heater as backup and therefore qualified for the State rebate. Since the install, my gas bill was offset by 80%. Well worth the investment.

Karin and I sat down 2 years ago and designed a system to meet our needs. Karin took time of use, aspect of the roof, and many other items into her calculations. Prior to the solar system my bill was $3000.00 a year, the first year with this system our electric bill was $75.00. Yes $75.00 for the year. Our system cost about 24K. We received about 8K in tax credits. This made the system cost 16K. with a 3K savings per year the system will pay for itself in a little over 5 years. I challenge you to find a more secure and better investment. 16K paying you 3K a year with no taxes. Stephen Thomas

This was a great experience from start to finish. Each person in the process proved to be professional, helpful and knowledgeable. I worked with Karin on the proposal and the contracts and she was timely and helpful at each step of the way. The installers were Pablo and Keith and they did a great job. They did the work on Sunday (yes, Sunday!) at no extra charge and made sure everything was done to exact standards. They took their time, explained everything to me and made sure it was working properly before they left. The pricing was highly competitive with four other different proposals, but only CleanTech offered a 2% discount for paying by check. It made their price the best. I would highly recommend this firm to anyone for this service. Great job!

Clean Tech did an outstanding job installing our solar, wiring our electrical, and planning the project. We were very pleased with the overall price as well. Our roof looks great and our neighbors are commenting that it looks good as well. Couldn't be more pleased. Thank you to the entire crew.

We have had the best experience with Clean Tech. Karin and her crew have been on top from the moment I called to express interest in a PV system. We are up and running in record time. She kept us informed on a near daily basis and her crew was dedicated to completing the job in a prompt and very courteous manner. Our system is generating at a high level. Because I have been a Clean Tech customer for many years (Solar hot Water), I am aware of their excellent after sales support.

Very good to work with I highly recommend Karin and her crew. Very nice clean professional installation.

Cleantech was a good company to work with. They completed the job quickly and professionally in the time and at the price agreed upon.

Great service. Great people. Easy to work with. Price was right.

We manage Homeowners associations and deal with a variety of vendors. Your team couldn`t have been more helpful, communicative and efficient! I called them just to thank them for their diligence and efficiency. Great experience and kudos to Karin Poelstra. She worked with the roofer and coordinated everything, making this job very pleasant for our team. Sincerely, Sharon Briskin, Owner Guardian Association Management

We had our original solarhart tank installed by another Solarhart representative in town. In the process of removing the tank for a re-roofing job, the other company`s workers dropped the tank off of the roof. They then replaced it with a tank that was constantly problematic. I realized I could no longer work with the original company In an effort to resolve my problems, and so I called CleanTech. Karen, at CleanTech, was able to contact the Solahart company and they made our warrenty good. Their employees are excellent and very professional, I would recommend them highly to anyone and they can use me as a reference any time. Tom Hatton, Solarhart owner since 1992

I had some bumps in the road with approvals from the City of Carlsbad and Clean-Tech took the lead on all of these and got all issues resolved.

The people at Clean Tech were great - they made all arrangements for replacing a damaged panel and getting inspection approval by the County of San Diego. Unfortunately SDG&E have not been as cooperative - the system has been installed and ready to go for over two weeks now but, still no word from SDG&E, except for a request for additional diagrams, when the project was first submitted.

Recommend this company highly (and already have to 2 other family members who are serioulsy considering a PV installation)
