60 cell solar panels and 72 cell solar panels. That translates to just over 15 watts per square foot. For any given energy production target you need fewer panels if their individual wattage is higher. In order to find a range for number of solar panels we compared arizona and maine s solar panel production ratios 1 31 and 1 61 the highest and lowest in the u s.

So for homeowners who want the most powerful solar on their roof the sunpower 415 is it.
