When I upgrade (by 1000 watts) I'll be using 250 watt poly panels with an MPPT controller. I may just start over and use 5 panels to get to 1250 watts.
That may be your best plan.
Just FYI, there is an outfit on the West Coast that makes a module that is somewhat transparent, i.e. lets light through the module surface. I'm sorry, can't remember the name. Their main application was for sun rooms and entry areas.
I thought of your situation with these being used over your existing Unisolar array. It may not work due to amount of light passing through and I would bet the pricing on them is astronomical.
