We started our search for solar panels in July of 2024. We called and received quotes from 3 other solar companies and made the decision to go with Sunline Energy based off the price, communication, and reviews that Sunline has.
Amber Simpson was our sales rep and she was by far the best rep from any of the other solar companies that came by. She was knowledgeable and gave us the run down of how things would work out and made her self available to us throughout the process. She informed us about the battery rebate that was going to begin and signed us up for it. Once we knew we were approved we went ahead and signed off on the contract.
I believe TEAM 2 - with Manny as the lead were the installers. The first day of arrival they walked me through the process and they got to work. 3 days later our system was set up and ready for inspection. TEAM 2 was punctual and organized. I was able to leave and go to work and not worry about watching them.
Sarah was our account manager, she communicated well with us and answered all of our questions.
The only issue, we had was regarding our solar panels. We chose the Maxeon panels, but we were told the day of installation that they were stuck in Mexico and they would not know when they would be released from customs. We were given the option to wait with no known delivery of the panels or go with the Panasonic panels. We were not very happy with this, but after doing some research into the Panasonic panels I was fine with moving forward with them.
Our system was completed on December 13th, 2024 and the inspection was done and passed on January 13th, 2025. We received PTO on February 6th or 7th, 2025.
The system is performing great as of now. No complaints.
Overall, the team at Sunline kept up with its standards of great customer service and I recommend them.

Ricardo and Jerson were so helpful when our inverter stopped working. The original Solar Company who installed the system went out of business . Sunline helped us get the inverter replaced by Solar Edge and it was covered under the manufacture warranty.
I paid Sunline for the installation and they were much more affordable (and helpful) than the other companies I called.
Plus communication was great via text and phone!

Sunline Energy did an excellent job guiding me through selecting and installing solar for my home. Amber is the best sales representative, she is quick to respond and will always find the answers to your questions! I also used Sunline to replace the shingle roof prior to the solar installation and Erin and Sarah were great to work with to line up all projects around our schedule. I would 100% use Sunline Energy again and highly recommend them for roofing and solar work!

Working with Sunline Energy has been nothing short of a nightmare. We signed a contract nearly two years ago for a new solar system and upgraded electrical panels, yet our system is still not connected. The company continues to give excuse after excuse, repeatedly blaming SDG&E—even when the mistakes are entirely Sunline’s fault.
One of the biggest failures happened when Sunline installed the wrong electrical panel. After waiting over six months for SDG&E to connect the system, the linemen arrived only to reject the installation because Sunline had installed a panel that does not meet SDG&E’s requirements. The issue? The panel lacked a required external locking ring—something any competent solar company should already know. Instead of taking responsibility, Sunline blamed SDG&E, claiming they were never told about this requirement.
Our tenants cleared their belongings for this appointment, only for it to be canceled last minute. On top of that, Sunline’s installers were unprepared, failing to install containment sheathing and floor protection when doing drywall cutting and drilling—we had to handle that ourselves. During a previous visit, they left a mess, including metal debris in the tenants’ yard.
The incompetence continued today. They were scheduled to install the correct panel at 7 AM—an appointment set a week ago—but canceled via email at 6:30 AM, claiming all their electricians had suddenly gotten sick. This last-minute cancellation pushes the installation out another week, further delaying the SDG&E connection process. At this point, we've been waiting nearly two years—this is beyond unacceptable. Meanwhile, friends who signed with other solar companies have had their systems installed and running in just a few months.
Sunline claims the electrical panel swap should take only 30-60 minutes. If they cared about making things right, they could have hired a subcontractor to do the job and take the required photo for SDG&E. Instead, they continue with excuses and delays. Sunline either doesn’t know what they’re doing or simply doesn’t care about their customers.
Given the ongoing delays and lack of accountability, we are considering filing a formal complaint with consumer protection agencies. If Sunline makes a genuine effort to resolve these issues, I will update this review accordingly. But as of now, I cannot recommend this company. If you're considering solar, do yourself a favor and choose a different company. Don't make the same mistake we did.

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.
