Unfortunately many solar companies lean towards the sketchy side. Fortunately, StraightUp is not one of those companies. We had them replace an inverter last year and it worked fine for about a year, then it quit and triggered an error code. The service crew came out and were on the roof for a bit, and when they were done, we were told no charge as it was due to an installation error. Mistakes happen, and I am ok with that, especially when the company owns up to it and fixes the issue at no charge. This is especially impressive since I am not an electrician, and would have had no idea it was an installation error unless they informed me. Kudos to the repair crew and kudos to the Service Project Manager for also proactively following up with more details. This place is super professional, and I highly recommend them for your solar needs.

I have several solar systems at a number of locations. I've worked with more than one company. I am pleased with StraightUp. Office management is very attentive. The field technicians are knowledgeable and work efficiently. The sales staff is respectful and listen to detail. Their repair and service prices are reasonable. This is the company I will be using for the foreseeable future.

They answered my phone call and sent an email to assure me they were on the question about my issue. Which was not an issue after all. Nico was very helpful and reassuring. I've had my panels for 7 years and am very satisfied and delighted with my power bills.

Straight Up Solar removed 6 solar panels to allow roof repair and then returned to reconnect the panels. The work was done in.a timely fashion when scheduled. When they ran into a shortage of parts for a 12 year old solar system, they had to extend the timeline but gave me a $100 discount due to the delay. I mean, what company does that today? Great customer service. I will definitely use them for continued maintenance and panel cleaning.

When we had our roof shingles replaced due to their damage in a hail storm, we had our solar panels removed for the roofing work and then reinstalled upon completion of the roofing work. The StraightUp Solar workers did an excellent job with both tasks. They were very efficient in their work and completed the tasks within the schedule and cost they gave us. After the reinstallation they tracked our solar system to ensure it was operating properly. I rate their customer service as outstanding!
