My wife and I did extensive shopping around on local solar companies in Paso and met with reps from three different companies. After talking with Chad, the choice to go with CalSun was a no brainer. Not only did they offer the best price, but their friendliness, efficiency and quality of work is top notch. Like another reviewer mentioned, Chad (owner) really does have your best interest at heart and if solar is not right for you at this time, I’m sure he would tell you. If it was possible to give more than five stars I would.

After years of thinking about Solar we finally decided to check it out. Had several companies come out and talk about different ideals on placement and all the costs. Mike came for CalSun and his customer service was a big plus. On time, explained the solar experience, talked about placement, the pros and cons. When we decided to go for it they handled all the process. We didn’t have to deal with getting permits etc. Wonderful. The installers were prompt, completed the job and cleaned up. So glad we did it with this company. Great follow up also.

In October of 2018 we started looking for a solar system for our new home in Paso Robles. Of the three companies we contacted Calsun, and in particular their sales rep, Mike Shaheen, was the most knowledgeable and responsive. Since we had no prior usage history, Mike was able to help us select and size the system for our needs. (All U.S. made components at our request.) So far it’s working out great. We’re nicely ahead of PG&E! In addition, we wanted to get the system installed before the end of 2018. Mike completed all the paperwork and permitting so that we could be scheduled ASAP. Mike was on hand during the installation as was the company owner, Chad, to explain the process. He also followed up by showing us how to use the computer program that monitors the system’s performance. Mike was punctual, informative and very helpful. All-in-all, one of the best contractor experiences we’ve ever had. Highly recommended!

On our home solar, Mike was “eyes on and hands on” with every aspect of the system design (we have trees), financing, the system installers, and putting the system into operation. Mike was both knowledgeable and professional while working with me like he was my best friend and only client. The system is working great and appears that I will be at a $0.00 “true up” at the end of the year. Great equipment and the installation crew was the best (fast and efficient) and kept me involved when certain decisions were necessary (this was important to me).

CalSun Electric & Solar has installed a Hot tub and solar system for our family. The service was outstanding. Pricing was competitive and when you consider the personal service, clear and concise agreement, and excellent workmanship, the cost was totally worth it. With regard to the absolute cost of the solar(rebates, tax incentives, etc), the system has completely paid for itself in less than 5 years! Chad from CalSun said this may be the case… but.. you’re never sure when you jump in. Now looking at it, and my electric bills, he was dead right! I will continue to use CalSun for solar upgrades, perhaps a Tesla powerwall and more electrical items as needed.

A+ for honesty and integrity! I called Chad about a small house solar system, and with several challenging roof problems, Chad spent a lot of time trying to make the system work to fill our electrical needs. He even contacted the fire dept to see if any codes would be a factor. In the end, he recommended AGAINST getting a solar system because he could only fit enough panels that would fill 50% of our electrical needs. This would still have been in the $20K-$34k range depending on back up batteries, etc. Other companies that I contacted DID NOT TELL ME THAT!. So buyer beware. Getting someone like Chad to do your electrical or solar work is rare. Thanks again, Chad. I’d recommend you to anybody!

If you’re looking to install solar on your home or business – look no further. Mike Shaheen is extremely knowledgeable and explained the pros and cons of adding solar power. Cal-Sun owner Chad along with Mike and the installation crew were a delight to work with. Competitive prices along with excellent service exceeded our expectations!

“Our experience with Calsun Solar was great!   Chad was on time and stuck to the budget. He took care of all the permitting…things could not have gone smoother.  I highly recommend Chad and his company.”

Chad W.

From the interview all the way to the final inspection Mike from Calsun was there for us. He answered all our questions accurately and timely. We are very happy with the results and the decision to go solar. We interviewed 2 other companies who were very competent as well but felt Mike was the best choice.

Daniel S.

Mike and Chad are very easy to work with. Honest , helpful and proactive. The whole process was simple and CalSun pricing was easily the best. They installed the roof panels in the perfect location and is practically invisible from the street. Highly recommended.

“DON’T SIGN a solar contract UNTIL you’ve met with CalSun.” BEST ADVICE I ever got. Everyone sells same panels, same converters… pretty much same price. So when selecting installer, pick the one that’s going to explain the alternatives, show up, deliver on schedule, follow up after install. From introduction to completion, you’ll understand why. Price, value, experience. Ask for Mike. You’ll thank me!

We had our home solar installed by Mike Shaheen at Cal-sun. After meeting with a few other companies, we felt that Mike offered a better price on a better quality product than the other companies. We also felt the most comfortable with Mike since he was honest, professional and super knowledgeable. He was very responsive and took the time to jump on a phone call with us whenever we had questions or needed guidance. We had a new roof put on our home at the same time and Mike went above and beyond to coordinate with the roofing company and make sure that things ran smoothly. We were very happy with choosing Mike and Cal-sun as our solar installer.

Going solar was one of the best decisions we’ve ever made, and selecting CalSun to do the work made all the difference. Chad was diligent and careful, thorough and time efficient. CalSun offered everything we were looking for, including competitive pricing.

Thanks CalSun for such a great solar project which exceeded all of our expectations. CalSun was one of four bids we obtained and the installation and performance of the system to date validates our selection of installer. Our 22 panel system was installed in two days including installing the inverter inside the garage. Your crew was courteous and clean up was complete. The output of the system in its first full month exceeded the production goal set, even with the rainy days. I would also like to thank CalSun for your referral program. After showing our system to a neighbor, they also used you for their installation. Thanks again!
