[RE-wrenches] Minimum Lux needed

[Ray Walters]

On module IV curves,  100 w/m2 is the lowest insolation level usually 
listed.  It would also depend on the charge controller or inverter being 
used.  I've seen arrays make power at below 100 w/ m2 if there is enough 
array to overcome the operating losses of the electronics.
