Wow, that is an awesome result. With a cooling panels on the shade side of the roof and water pipes behind your PV panels on the sun side you can boost solar PV production by 3 - 5%. PV panels become less efficient when they are hot, we put some drip irrigation drippers on roof behind our panels (the panels are about 4" above the roof surface) and the evaporating water improved production by 2% on otherwise hot days.

Do you mean 2% or 2 percent points?
2%, in my case generating nearly an additional kilowatt hour per 24 hour period (33.8kwH vs 33.2kwH).
