A1 Sun Inc.

So, how do I rate a contractor? (1) Communication. From telling me what's being done to why to when it's being done, I want someone who will communicate with me. I have NEVER worked with a company more communicative than A1 Sun. I knew when they were coming, what they were doing, how long they were going to be there, and so forth. If I had a question, I emailed them and had a response within HOURS, not days. They were truly an amazing group to work with. (2) Quality of work. I work from home, so I get to watch the work from start to finish and yes, I pay attention. They did excellent work throughout. (3) Quality of workers. The people who came to work on my house were uniformly wonderful, up to and including knocking on my door to suggest that I bring my "little ones" (cats) inside just in case anything fell off the roof (nothing ever did). They were conscientious. They were friendly. I honestly enjoyed having them around. How often can you say that about the workers at your house? (4) Clarity of the bill. I got an itemized bill before the project started. I was warned of one cost overrun because of dry rot in my roof. I paid EXACTLY the estimated amount, plus EXACTLY the overrun estimate. Nothing like knowing exactly what you're paying. (5) Ease. They showed up. They did everything. They even handled the PG&E paperwork. I signed one e-Document and now I have solar power. Couldn't have been easier! In short, they were fast, they were friendly, they told me exactly how much it would be up front, and they did quality work. I cannot imagine hiring any other solar company after having worked with them. (Yes, I'm copy-pasting my review from Yelp. I liked them so much I'm hitting a bunch of sites)

Our experience with A1 Sun has been stellar. After researching all the local solar company options, we were so grateful to have found and settled on the best. We had our panels installed three years ago and they have been generating and making us smile at our PG & E bills ever since. A1 Sun truly cares about each and every customer and is committed to making it as easy as possible for you. They, not you, do all the hard work, including the permits, paperwork and installation and followup. It was a great pleasure working with Larry, Kathleen and the rest of their crew. Thanks again A-1 Sun!

This Oakland/Berkeley based solar company is absolutely first rate. From the time of the first meeting (estimate) to the completion of the job I had no problems. Everything was done professionally and the workers were on time and worked hard until the job was completed. All of my questions were answered completely and quickly. I really did not need to do anything including the potential hassle of dealing with PG & E to get hooked up to the Grid. I think for anyone interested in installing Solar, AI Sun could not be a better choice.

System installed Dec 2012. No options on tilt of panel, but they did raise them to reduce shading from nearby building. No problems with the installation, which was quick. Panels were U.S. made per customer request (Sunpower). System uses Enphase inverters. Installation on a second house 2014. They came out to make a bid, and noticed roof was about to be installed. They installed standoffs that day without a contract (saving us some money). We accepted their bid, and again the installation was done promptly without problems. Very pleasant to work with.

I was skeptical about installing a solar energy unit. Had bad experiences with two large companies. Found a smaller, local company in A1 Sun. They are a pleasure to deal with and and provide good value. I could not be happier with the service and product they provided.
