CIGS solar roofing tiles are (or were, not sure you can still get them) about 6% efficient. These are, according to what was in the TechCrunch article are over 20% efficient[1].

[1] I got there by taking the '98% as efficient as regular solar' from https://techcrunch.com/2016/10/28/these-are-teslas-stunning-... and the current 22% number advertised by Sunpower here : https://www.greentechmedia.com/articles/read/SunPower-Breaks...

DOW's CIGS was pretty garbage compared to Certainteed's Apollo II system, which achieved 13.2% efficiency. [1]

There are also up-and-coming competitors such as SunTegra that hit 14.6% [2].

It seems like asthetic options and possibly efficiency improvements is what will set this apart from previous stumblings in this space. We'll see how this looks in the real world!
