It will be interesting to see if the pannels put forth the intended wattage. One of the most motivated guys exposing the stratospheric injection of nanoparticles for solar radiance dimming program (geo-engineering) had a huge solar array up in northern California (as I recall) and he started noticing about a 60% drop in power from the areosol spraying of nano aluminum, barium, strontium etc...
Still I'm sure you will enjoy lots of power from the sunshine. What a great project you're working on!
