Everything was seamless and delivered as promised.

They maintained excellent Communication during the entire process. The installers were very clean, friendly, and knowledgeable. The system was turned on and I saw my electric bill take a dramatic drop immediately. I would highly recommend Ben & llum Solar to anyone, especially friends and family as this was actually a really great experience.

There are few companies that I would rate 5 stars.
Ilum Solar is one of them.

As a retired electrical engineer and home owner I carefully monitored the workers during the installation and the finished product. The workers were very friendly and did not appear to be bothered by my monitoring them. I could not be more pleased with the quality and care of the installation.

Installation on our home was professional and fast.

The team were courteous and took all the steps to guide us through the install, inspections and final testing of our system. I would highly recommend using Ilum for your solar needs.
