Leaks! Beware!!

I hired Sunergy 6 years ago. Originally, they did a good job, but here are the problems I've had since the install: 1.) Leaks! There was water intrusion into the inverter!! They "fixed" it by drilling a weep hole. I don't know about you, but I'm *still* concerned about high voltage and water in the inverter! 2.) Leaks in the roof. They do not have proper on-call processes in place when their office is closed. I notified them about the leak and they were only able to get someone to the house to take a look 2 weeks later. 3.) They tried to skirt around their responsibilities to fix the actual damage in #2, and only wanted to put some caulk on the leak. Then they proposed an obviously sub-par (but cost-effective for them) solution to prey on an uninformed homeowner. 4.) They clean your panels with soap that has caused permanent stains on the panels. It has probably caused some loss of production due to this. Given my experience, I can no longer recommend Sunergy Systems.

Great sales and instillation

Great company to work with, and I’m very happy with the outcome. Minor bump with the final billing as it went to my spam folder and immediately I received a delinquency notice. Mind you I had already paid for 85% or 90% of the total bill. A phone call would’ve been a lot nicer. However, the outside – they were fantastic with scheduling, the work people were meticulous, and the sales person went above and beyond every single time we met. I would highly recommend this company. On a reasonably sunny day my output is exactly what I want, and on a sunny day I am thanking Solar for those gray winter days ahead.

Sunergy Solar + PowerWall install

From the sales consultation through installation the experience was Sunergy was great. They provided a comprehensive and detailed analysis of our technical options, costs, and payback. The install team was on time, did a great job, and left the job site in great shape. We're very happy with our new solar system!

Thrilled with Sunergy!

When we mentioned thoughts of solar to a coworker, she said, "let me tell you about Sunergy!" She and her husband were very happy with their system. We would much prefer a live, word of mouth recommendation to phone solicitation or a flyer in the mail. Sunergy had been everything our friends said. They are prompt, professional, and downright friendly. The office staff is very responsive. The installers were on time and incredibly clean in their work. And bless them, they installed our system in January---anyone remember January rainfall . Weve only had our system a short time and can SEE it working vis the easy app. We look forward to years of clean energy and continued service from Sunergy.

Great to work with

They were very responsive. It took a little time to get on their schedule, but the install and activation went smoothly.

I have had my 12 panels installed for a few years. My PSE bills have been about $10/ month except for three times. The last one was last month when it rained all month. Even then my bill was $20. I figure my system will have paid for itself next year.
