Homemade Solar Panel Tilted Single Axis Sun Tracker

Here is my first attempt at a solar panel tracker (tilted single axis). So far I'm just powering the linear actuator with a battery (sorry) but I will make an Arduino powered sensor array of some kind soon to do it for me.

During the sunlight hours I get about 325 watts just from these 4 panels (after the inefficiencies of the wire/inverter). I have 4 more to make another one of these trackers with (and with both arrays I get 650+Watts).
