CSC did a very good job from beginning to end. They hosted an online seminar to explain the process of getting a solar installation, the ins and outs of financing the installation, how the system works with PG&E - the works. When I requested a solar evaluation, the written evaluation and estimate was very complete. It accounted for the location and orientation of my house, the type of financing I wanted, my average PG&E bill over a 12-month period - and then showed me the savings over time and at what point the system would pay for itself. My installation was a bit unusual - a ground installation on our steeply sloped back yard, with the array tilted at a compound angle to maximize sun exposure. They did a great job with it. The array actually looks pretty cool in my back yard, and I very much enjoy watching the monitor as those Megawatt - hours keep piling up!
I absolutely recommend CSC, and buying - not renting - your solar array.
