12 x 360w panels at 21 2 efficiency 4 300 w.
Highest percentage solar panels.
These solar panels have higher than average efficiencies and also come in at a higher price tag.
It probably comes as no surprise that california ranks first among states in generating electricity from solar power.
The top honor was claimed by.
Sunpower panels are known for being the most efficient solar panel brand available on the market.
The golden state generated more than 37 percent of the u s.
For example 12 x high efficiency 360w solar panels such as those from lg or sunpower with a 21 2 conversion efficiency will provide up to 1100w 1 1kw more total solar capacity than the same number and size 270w panels with a lower 16 5 efficiency.
12 x 270w panels at 16 5 efficiency 3 200 w.
The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.
The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.
So if you plan to use high efficiency solar panels keep in mind that your solar panel installation could end up costing you more money than if you used standard efficiency panels.
