Solar panel efficiency refers to the percentage of sunlight that a solar panel can convert into usable electricity. For example, if a solar panel has an efficiency rating of 20%, it means that 20% of the sunlight hitting the panel is transformed into electrical energy, while the remaining 80% is either reflected or lost as heat. Generally, the higher the efficiency, the more electricity a solar panel can generate in a given amount of space, which is especially important in urban settings where roof space is limited.
