Maybe I'll give an overarching comment. I would say, relative to your first comment, really the uncertainty in the end markets, I guess, a year ago was really being driven more by the Suniva trade case and the resulting potential cost increases on panels. How that would affect various end markets as it relates to utility-scale solar, whether it be in the trackers area or utility-scale solar as it relates to fixed tilt. To a lesser degree, how would it affect – those are two areas that we don't – we don't do large scale. We do community-based solar. It's smaller scale. So, we were more insulated against that, but certainly, it was for 2017, viewed by the market and industry experts that it was a headwind. We were less exposed to it just because of the type of the business we do. Everybody knows that trade case went through, the relative impact on panels for that operating – the balance of that operating year and certainly in 2018, 2019 and 2020 going forward is that panel prices have actually come down and are far under some of our best operating years from a market and the industry experts and Tim can reference some of them, and he did in the script, that the market is – continues to be a rising tide and it's going to expand in future years. So, I think that's an important element. The ITC, it's still out there. It was kicked down the road. And I think it expires now in 2021 area. So, that becomes, I guess, an artificial cleft, but to really a lesser extent, with 54% of new power generation investment going towards solar, that's not the same material impact it would have had when it was originally forecast to come to an end at the end of 2015. So, I think missed in all that is less of a shift that was forecast from fixed tilt to tracker. I think, as we've said all along, and as we've entered that market in a small way, the transition from fixed-tilt to tracker on large scale or community, certainly on community solar, we don't see a strong evidence of it in a material way. Our backlogs are up year-over-year both on our fixed-tilt systems, and we continue to grow on a crawl, walk, run basis in the tracker space as we test and implement and refine our new system design. So, Tim, you want to add some…
