UPDATE: My Sattler Solar system has been working flawlessly until a few days ago 1 panel was under producing (I noticed on the app Sattler set up for me). I messaged Sattler and they confirmed there was an issue and quickly created an RMA with the manufacturer and swapped out the bad micro inverter. Excellent communication, even following up after to confirm everythingwas back up to where it should be. Incredible support and service, even years after their install.

After about two years of consideration, we finally decided to invest in a solar system, in part because we learned the federal tax credits are going to eventually be stepped down. After getting quotes from five popular companies (both national and local), I got frustrated with the margin that was being charged for the service. I priced-out an equivalent system as if I was going to purchase and install it myself. I then called some solar system suppliers and asked if they could advise on my project or put me in touch with an individual consultant (who I would pay to help design and install the system). I ended up getting put in touch with Erik Sattler of Sattler Solar. He's a German solar consultant who was not only able to source the solar components for *CHEAPER* than what I could have bought them myself (online), he also charged very reasonable rates for doing a full owner-builder assisted install. What this really means is that I got to do a lot of the work, but it was more like I was his assistant and he was the lead. I loved doing it this way because a) I learned so much more about my system than if someone had just installed it all for me and am confident that I could deal with pretty much any future issue that might arise (although everything is warrantied for 20+ years), b) I saved around $15k compared to quotes from the large companies, and c) we got it done in a fast-tracked way that I don't think the larger companies would've been able to do...thereby locking us into NEM 1.0. If you're thinking of going solar and have the time and skills (basic DIY skills will do), I highly recommend this approach because of the tremendous money savings and the ability to get really involved with a system that's going to be with you for decades. I'm sure most people know this, but if you're going to re-roof your home at any point in the near future, it may be cost-effective to do the solar system at the same time. I must say that I am very happy with our system. We've had it for 2.5 years now without a single issue--other than getting a little carried away running the A/C even when we don't really need. to. ;-) Cost wise, the system estimate was 0.041 $/kWh. If anyone finds a better deal than that, please do everyone a favor and post it!! If you want to know more about my experience, my system or Sattler Solar, please message me directly. Thanks and good luck.

Erik is a solar demigod! He gave me 3 options, and helped me recommission an existing system with new panels. Improved my production 50%! He did all the math for me, and all I did was simply provide him the info he requested. Daniel was a professional installer, and I loved the care he took with by brand new roof! Would absolutely recommend you save yourself some time and $, ans call Sattler for a quote. Aloha!, Lane

Very professional and helpful. Every step was fully explained and every question answered thoroughly. Work was expertly done and the finish was very clean and professionally looking. Kenny and Vanessa were always there to assist. The workers were very respectful, courteous and conscientious of surroundings. Definitely above and beyond. Very highly recommended.

Great small business to work with!! Erik and Vanessa both helped to make plans, obtain permits, and supply all materials for my ADU project. Even though my project is a smaller job, they both were super responsive with every request.
