Its all ways a trade off.
However, my static 3kW PV frame cost me about $400 in materials, concrete, steel, rails, cables etc.
My 2kW trackers cost me about $1100 in materials, concrete, metals, activator ram, Daves Australian Electronic control, (LED type sensor, but looks every 10 minutes, and auto parks at night) etc. But I get a 1/3rd more output than the static array over the year.
Using good MPPT controllers, means I can squeeze a good 10% plus out of the PV in ambient light conditions.
For home built stuff, that's cost effective, I have found that 2kW size, 8 x 250W, is the max size to play with in those violent Winter storms.
