The whole process was suppose to be 2-3 months from start to finish. Throughout that process Sustainable sent numerous incorrect application forms to PEPCO, sometimes sending in forms from Maryland instead of DC, submitting specs above what DC allows, and without a required filing fee. Finally Sustainable screwed up another filing form and opted to forge my signature rather than let us know they made another mistake. When I saw the fake signature and contacted them they explained it was done to save me time since I previously signed a similar form. After that we had to fire them and received a refund of our deposit.
Aside from the lack of professionalism the system they were building had a few less than desirable features. First they were going to mount it directly to my roof against the recommendations of my roofing company. We had asked about a mounting system that spanned party walls and sat elevated but they said they did not install them because of quality issues. They also were using just one inverter for 17 panels, rather than individual micro-inverters on each panel. The company we selected to correctly do the install said both of these were not best practices. In the end the new company completed the full install, with better solutions, in six weeks compared with the seven months of failed attempts to even get started with Sustainable.
Sustainable had very polite staff that seemed energetic about what they were doing. However I can not recommend anyone use them given the numerous mistakes, basic lack of any quality control, and likely illegal activity (forgery).
