Great system, honest local installer.

Solar is a BIG purchase, but Cascade Solar made it a transparent, honest one with skill on install, flexibility in scheduling, a competitive price per watt compared to most, and access to a lender specializing in green lending at market or slightly-below market rates. They communicated great throughout and the process is more streamlined with them than two other firms installing for different friends of ours were. Our experience with bidding firms was wildly divergent - from “that big firm” that felt like dealing with a bot, to other mid-tier firms that frankly padded their bids (one firm quoted the same price for final install that we had for CS, but for 60% the array size!). Our Enphase system is performing as advertised and the backup Powerwalls give us a bit more assurance in outages which have become all-too-common in PDX winters. They got us to a reasonable cost per watt installed with high-quality components, took care of the permitting and inspections, and did a final walk-through meeting to test our system performance and make any adjustments needed. If you are considering solar, give these folks a call. There are a lot of shady characters looking to make a mint on folks not doing their due diligence. Cascade Solar is local to PDX and absolutely worth your time to consider!

Amazing End to End

I recently had Cascade Solar install an 8.6 kW system in Oregon City, and I couldn't be happier with the experience. The sales rep was low pressure, making the decision-making process stress-free. Working with Cascade Solar was great, and their pricing was competitive. Communication throughout the entire process was perfect, keeping me informed every step of the way. I highly recommend Cascade Solar for anyone considering solar installation, and I’ll likely be working with them again in the future for a battery installation.

Excellent Installer, Great Customer Service

Cascade Solar was excellent to work with and did a great job installing our home solar system. From the start, David Nicholls was professional, knowledgeable, responsive, and very patient in answering all the questions I had regarding the project. He worked with me to evaluate different sizes of arrays and different equipment options, in order to best meet our current and projected energy use. Cascade Solar’s pricing was the best of the several bids I received through EnergySage and elsewhere, while also including components featuring the latest technology. Once we settled on a design and decided to move forward, David worked hard, under tight deadlines, to ensure we received the best incentives and rebates available. When it came time for installation, David and his crew did a very professional job, and he subsequently returned to ensure everything was in good working order and answered any further questions we had. It was a pleasure working directly with an owner of the company who truly cared about making sure the customer is satisfied and the job is well done. I highly recommend using Cascade Solar.

Complex system, great work

My system was a large and complex system involving permitting from all levels of local and federal authorities, and Cascade Solar handled it all without me having to deal with the legal complexities. The work was professional and looks and works great. I would definitely recommend Cascade Solar to anyone wanting to go solar....

Great Company

Cascade Solar did an amazing job on adding batteries to my existing system. What I thought would be easy, turned out to be more difficult because of the age and arrangement of my old system. However, they came through with flying colors, providing me with an affordable solution. The system has been running flawlessly for several months now. Besides their technical expertise, I was impressed by how they communicated clearly and promptly.

Very pleased with Cascade Solar

From the beginning to the end, Cascade Solar exhibited patience, courteous behavior and in-depth understanding of the project. It did not push us to make a hurried decision, answered any questions that we had, and provided an excellent value for money, and found us an extra incentive from the state. It moved our schedule up to accommodate our travel plans. It educated us on all aspects of the system including, material, installation, and monitoring the system. It set us up with monitoring website and followed up with us to make sure things were working properly. For us the, the most pleasing aspect was the owners installed the system and there was no third party to deal with.
