Solar Energy System reviews in Sacramento, California

Got solar last year and they helped me get the best deal. Workers were very knowledgeable and got it done very quick.

Thank you ILUM SOLAR our electricity bill goes down great price. It’s highly recommended. Thank you

Ilum Solar was easy to work with and did an excellent job accommodating my concerns with their installation location. All in all, a great experience, I would definitely recommend. The solar is definitely saving me $ too.

I had a great experience working with Ilum Solar on my solar + Powerwall installation. The team was organized, communicative, and committed to meeting the timeline we discussed. Even when the installation date was pushed back at first due to weather and the busy season, they worked out a plan to squeeze my project in and still complete everything within the original timeframe. That flexibility made a huge difference.

They completed the full system installation on schedule, and thanks to their guidance and follow‑through, my PTO was approved shortly after the project wrapped up. I worked closely with David and Jeff, and both were fantastic—knowledgeable, responsive, and proactive in making sure everything went smoothly. The installation quality is professional, and the system has been performing exactly as expected. Highly recommend!

Very shady business practices
