IMO panel choice is the least important consideration; Even racking is more important. If you want black panels for aesthetics get black panels. If you're space constrained get higher wattage panels; If you're on a budget get the cheapest ones (So long as they're UL) even 'B' grade is fine IMO. I've bought B grade.... it's usually just a cell misalignment that doesn't effect performance and can only be see if you're on the roof inches away from the panel.
If cost is a concern Renvu is selling Talesun panels for $0.36/w.
