Solar thermal panels might be wonderful for heating up water or buildings, where the target temperature is fairly low. However, as the target temperature goes up, the target starts radiating that heat energy back out, which is where this innovation could be useful. So, it's useful for applications where you want a higher temperature than most solar heating applications now.
