We had an amazing experience working with Cinnamon Energy Systems to install our solar panels and battery. Michael Croft was our primary point of contact, and he guided us through every step - from exploring our options to making sure everything was working smoothly after installation. He was always prompt, clear, and proactive in his communication, helping us stay on track and meet our goals. We highly recommend Cinnamon for their expertise, reliability, and great customer service!

I sent a kiln outlet installation request via yelp and LCX energy is the only company replied asking for which brand and model I planned to get so they could do some research before they come and give us an estimate. That's the main reason my husband and I decided to hire them for the project. The estimate was reasonable. Everything went smoothly and efficiently. The work is very neat. This morning, I ran the test fire for my kiln and it reached the proper temperature in 7 hours and a half smoothly. I can't be happier. Will definitely hire them again if we need help from electricians.

Cinnamon Energy Systems installation panel crew were fantastic. They did a great job in a timely manner as well as picking up and not leaving any trash behind. Very polite and knowledgeable crew.
The electrical pair James & Newman were super! They explained before and after the battery & power wall installations. Again the area was completely cleaned from any trash. After a brief discussion, they even had an excellent alternative for some wiring (copper) to be installed and not be so visible.
I would highly recommend Cinnamon Energy Systems for your solar needs. I look forward in using Cinnamon for my future needs (HVAC).
Happy & satisfied custom. Sterling Makishima

Cinnamon did a great job for us replacing, expanding, and adding whole-house battery capability to our solar system. Jessica at Cinnamon did a fantastic job speccing out the project, walking us through how the new system would work, where we could expand our capacity and matching our system to our energy use. We decided to replace our roof at the same time, and Cinnamon worked seamlessly with the roofers. The installation was done quickly and as expected. We ran into a glitch with final County approval, due to some personnel changes at the County, and this necessitated some rework. Cinnamon (Jack, Mark, Paula, Joanne and Jessica) were straightforward, proactive and transparent about this issue and we addressed it effectively. Our system is up and running and we love seeing how we are not using PG&E basically at all (for electricity at least)!

One thing that is really great about Cinnamon is that everyone is very responsive. If you have a question or send an email they get right back to you with a real answer.

This past December 2024, we had to replace the entire roof on our hone.  This required removal of our old PV solar panels and PV system.  We signed with Cinnamon Energy Systems (CES) based on a high recommendation from Los Gatos Roofing.  Randy from CES came out for the initial survey and we discussed what the new system would look like.  Randy gave us a proposal for the new system, and he made some adjustments per my review and recommendations.  Jonathan from CES came out and did the technical survey and drew up the plans to be submitted for permits.  Please keep in mind that there have been some recent changes in the fire code that affect where and how battery systems such as the Powerwall 3 can be installed.  Both Randy and Jonathan were very thorough and provided details on the fire code.    Once LGS gave us a schedule for when they would replace the roof, CES scheduled a crew to remove the existing solar panels one week before the roof replacement work.  Their crew came as scheduled and went to work.  It wasn’t until February 2025 when CES was able to install the new solar panels and the Tesla Powerwall 3.  Note that there are some things that are not in the installer’s control such as permit reviews and approvals by the city.  PG&E also have to install a collar on the meter.  Also, the Powerwall 3s are very popular and are in high demand so some time may be taken for Tesla to deliver the Powerwall 3.  After the installation and startup of the Powerwall 3, it turned out that Powerwall 3 was failing diagnostics.  Not to worry, the CES crew contacted Tesla while on site and they worked together to diagnose what was wrong.  Tesla determined that our Powerwall 3 was defective and would ship a new one.  It can take more than 2 weeks to get a replacement.  CES however, decided to pull another Powerwall 3 from their inventory and install it.  It was installed and passed all diagnostics.  It’s now working properly.

The crew at CES are well trained, talented, professional, and great to work with.  Paula at CES managed the scheduling and was also great to work with.  She kept us posted on the project schedule.  As I’m into technology, the CES crew didn’t mind me watching them work and looking at the technology of the Powerwall 3.

We highly recommend CES if you are looking for a PV solar system.  5-stars.
