While your critique is certainly true of the first generation of trackers, I'm not sure if you're familiar with a company called Qbotix[1]?
They're just one example where innovation in the space is producing cheaper and more reliable tracking. The basic idea is instead of having per panel tracking devices, rather, use a simple robot run around a fixed track and adjust the panels as needed. Then repeat again and again, throughout the day. If the robot malfunctions, swap it for the spare.
