Most Efficient Solar Panels

If you have limited space and need to get the most energy for your area, then you need the most efficient solar panels for your project. People always ask me, “which panels have the highest efficiency?” or, “which solar PV panels are the best?” The truth is that solar panel efficiency isn’t as important as you might think. For most homeowners, the better question to ask is, “which panels will give me the most electricity for the best price?” You can find out how much solar might cost for your home by using our free solar calculator. But you’re here to find out the most efficient solar panels, so let’s get on with it.

The most efficient solar panel in 2016 is the SunPower SPR-X22-360 with a 22.07% panel efficiency.

Below is a solar panel comparison chart comparing the solar panel efficiency of all other modules rated at 360 watts like the SPR-X22-360. The 360 watt rating means that in strict laboratory conditions, these solar panels produce the same output. However, because solar panels vary in size, some end up being more efficient compared to others – meaning they can produce the 360 watts using less space (area).
