Solar panel efficiency rating measures the percentage of sunlight that gets converted into usable electricity. There are two ways to measure photovoltaic solar efficiency: You can look at solar cell efficiency or at solar panel efficiency. Solar cell efficiency is the amount of sun light that the individual solar cell converts to electricity

The greater the efficiency, the less surface area it will take for the solar panels to meet your energy requirements.

Some people associate greater efficiency levels with higher-quality panels, but this isn’t necessarily true. High efficiency means your solar PV system will utilize less space. Therefore, those who live in high-density areas and have very limited space for solar are generally more concerned with efficiency levels.

The current efficiency leader, multi-junction solar cells work by combining rare semiconductor materials with differing band gaps—such as germanium, gallium and indium—to convert a broader range of the solar spectrum into energy.
