Our experience with Sunline has been one of the worst we’ve ever had with a company. We decided to expand our solar system by adding more panels and two Tesla batteries. After extensive research, we narrowed our options to Sunline, Baker, and Semper Solaris. We ultimately chose Sunline for two reasons: their financing options and their use of Maxeon panels, which are high-end and highly efficient.
Initially, everything seemed fine—they provided all the necessary details. However, we couldn’t use their financing company and had to secure our own, which wasn’t their fault. The real issues began after we made the initial payment for permits. From that point on, communication was virtually nonexistent. Weeks passed without any updates, and we had to repeatedly reach out to our Sunline representative just to get basic information about our permits. We understood the process takes time, but proactive updates would have been appreciated.
Once the permits were approved, we were eager to proceed—only to be told that the Maxeon panels were unavailable due to customs delays. Our only options were to wait indefinitely or accept Panasonic panels with two extra panels as compensation. Wanting to complete the project before SDG&E’s price hikes, we reluctantly agreed.
The installation was scheduled for December 17-18, but after those two days, a significant amount of work remained. Because Sunline doesn’t work on Fridays and the holidays were approaching, we had to wait until after Christmas for them to return. Throughout this process, the project manager was disorganized and consistently failed to provide accurate timelines. My garage was left in disarray for weeks, and my wife and I had to take multiple unplanned days off work to accommodate the installers.
To top it off, when the installation was nearly complete, the workers discovered extra panels—our promised compensation for the unavailable Maxeons. When my wife informed them, they didn’t believe her because the project manager had failed to update the work plans. This mistake led to yet another delay.
Now that everything is finally installed, the system is functioning well, and I sincerely hope it stays that way because I have no confidence in Sunline’s ability to resolve future issues. The way they manage projects is shockingly unprofessional, and if they don’t make major improvements, I wouldn’t be surprised if they go out of business in the near future.

Excited to start my new solar journey with Sunline! Customer support and communication has been top notch. Henry and his team were friendly, professional, and fast. They were able to install the panels in one day and the job looks spectacular. My friend recommended Sunline to me and I’d do the same. Time to go green!

We had our solar panels installed over the past day and a half by Team 1 and they were so easy to work with. They were courteous, on time and kept us abreast of what to expect now and in the coming weeks. Thank you Allen, Rome, Habib & Nawin. Really appreciated your professionalism.

We had Sunline put in a small 2.8KW system, plus Tesla PowerWall, in our house in Mission Valley.
Everyone at Sunline; from the sales team to the Inspections team; were truly polite, responsive, and a sincere pleasure to work with and do business with.
I do also want to give a huge shout out to Sunline Instillation Team #1. Having Henry, Allen, Jamie & Nawin; all working the install, made me extremely confident that the project was going to be performed in a professional manner.
They were all true craftsmen.
In conclusion, a very positive experience with Sunline, throughout the process.
My only lesson learned that is worth mentioning in the review: SDG&E has the vendor set up and lock your Powerwall so that it can be charged by solar only (you cannot charge off of the grid). This unfortunately will NOT allow you to charge during the super off peak rate (from midnight to 6 am) for use on a cloudy or winter day… So you could end up occasionally paying SDG&E’s exorbitant rates under NEM-3.

I have been impressed with Sunline Energy from start to finish. I set up an appointment for an estimate and Matthew sat down with me in June and went over all options. He was knowledgeable and listened to my concerns and questions. I signed a contract and made a deposit.
Liz was the project manager who made sure everything was scheduled, including surveys installation and inspection. Liz scheduled us for installation in August but got our project going even earlier when an unexpected vacancy came up on Sunline's installation schedule.
Mike was the final person who brought the project to final completion ahead of schedule. There was an unexpected glitch in the San Diego Gas & Electric (SDG&E) inspection and approval process. Mike not only got everything corrected, but he also got the final permission to operate our Solar Power System from San Diego Gas & Electric days earlier than expected!
I tried to work with a different Solar Power Company before turning to Sunline. The other company quoted a higher price for fewer solar panels and warned about probable added expenses once the project was in progress. I signed a contract, put down a deposit, and then that company stopped answering my emails, texts, and phone calls. I fired them and got my deposit back. That was a blessing in disguise. Sunline installed more solar panels for a significantly lower price than quoted by the other company. Sunline always answered all my communications quickly. There were no unexpected expenses. The price quoted stayed the same from start to finish. I am incredibly pleased with Sunline Energy.
Months later the system is working fine and saving me a lot of money!
