Solar Panels Comparison Efficiency

Solar panels comparison efficiency.

These days the average efficiency of a solar panel is about 18 7 percent. This is in the top 5 of module manufacturers. Solar panel efficiency is one useful metric used to determine how much power a solar panel produces compared to other products. 12 x 270w panels at 16 5 efficiency 3 200 w 12 x 360w panels at 21 2 efficiency 4 300 w.

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. What is solar panel efficiency. For those looking for the most efficient solar panels for their solar energy system the first thing you need to know is how to compare efficiency metrics for different manufacturer brands. Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity.

The most efficient solar panels commercially available today have solar panel efficiency just under 23. The graphic below shows how dramatically solar panel performance has improved over time. A higher solar panel efficiency rating means a panel will produce more kilowatt hours of energy per watt of power capacity.
