With an automatic light tracking system your solar array will be pointed directly towards the sun all the time. This would be done automatic in realtime with the help of robotic scaffoldings of the same type as some of the large solar farms are using. The price of a system like this is likely to be expensive and will probably not pay itself off with just a small number of home solar panels bracket. Not unless you are able to cut the costs by manufacturing the scaffoldings yourself. We still believe that the moving parts in the scaffolding would have a high chance to brake down a couple of times, during the 25 year old lifetime of a solar panel. Making the system more of a cost then what you will gain in having your panels tilt angle pointing towards the sun at all times. And not to mention the moving of the panels will cost you energy. That energy will naturally have to be taken from the excess energy you make on moving the panels around in the first place. This will cut down the winnings on having a solar tracker a lot. Still it could be a fun DIY project for the hobby engineer.
