Nexus Energy Systems isn’t just a solar company, our roots go back to custom home building through Rietkerk Construction, founded in 1978. When we adopted solar into our product lineup in 2008, we had one clear advantage over our competitors that has stood the test of time – EXPERIENCE THAT MATTERS.

our customers say it best

From the salesperson to install, and amazing experience. I was able to be up and running in less than four weeks from sign up. The install crew was fast had the job installed in one day. Color-matched our stucco on all related piping and upgraded the main panel with ease. I would highly recommend Nexus to all.

Wayne Burnham

Nexus energy is a wonderful company to do business with. They have the best looking solar panels you’ll ever find and they also include bird netting around it. You can’t go wrong with an nexus energy!!

Jode Ann

From beginning to the end this company delivered everything as promised faster than expected without me ever visiting the city office or applying for anything. All I had to do was agree, sign, pay, and now I have solar panels on my roof. Bill and Tony did an excellent job at installation including color matching the conduit pipes to the wall, eve, and roof tile. They took time to install correctly in three different arrays. The panels look beautiful all black frame and enphase app let's you see exactly how much electricity is being generated. If you are thinking about solar don't go anywhere else. This company is it. And don't even think about going with anything other than micro inverters by Enphase.

Shin Rad

Professional from pre-sale all the way through installation and follow up. A slight conduit routing error was made during installation and they came back out and fixed it, truly a marker of a good company. Good monitoring software and customer service all around. I was weary about the process of going solar due to the number of flakey companies out there, but I basically e-signed the papers and literally they took care of the rest. Highly recommend!
