Solar Panel Efficiency
Solar panel efficiency refers to how much sunlight a panel can convert into usable electricity. Higher efficiency panels require less space for the same power output.
10 years ago, a 13% efficiency solar panel means one square meter of solar panel is around 130 watt, today this number almost doubled thanks to the breakthrough of the solar panel development.
