Given the existence of passive solar trackers that work mechanically, it's really hard to see how a complicated active tracking system could possible outcompete for a PV system. However, the company in the article is involved in concentrated solar power, so perhaps the situation is different enough to warrant such a system. I can _sort of_ see how there could be a feedback loop where changing ambient temperatures and radiative heat from the tower might effect the reflective array in complicated ways that would make it hard to maintain a very tight focus point. And, if tightening the focus point of the array can double or triple the incident W/m^2, maybe that gets past some sort of pass/no-pass temperature threshold that allows for higher overall energy conversion....
