Anyone can recommend a reasonable priced ground racking system for 30 large panels? Does tilt adjusting really make a good difference in overall solar power you get? Do I really need this feature or a fix system is OK.
A tracker that adjusts in two planes can yield up to 40% more PV output (from what I've read). However, is it worth the cost? There is a school of thought that adding a few more non-tilting panels alleviates the need for a tracker.
