Almost 100% of the module is covered with solar cells to produce superior power and exceptional efficiency.
So, what is solar panel efficiency?
The phrase ‘solar panel efficiency’ describes how well a solar panel captures sunlight (irradiation) and converts it into usable electricity. In normal environments, a high-efficiency solar panel will generate more electricity than a lower-efficiency solar panel of the same size. Put simply, a higher efficiency rated solar panel is mostly a better choice.
Higher efficiency means that less total solar panel area is needed to deliver a given power output, leading to savings on balance of systems components and labour. Efficiency makes make a huge difference in the extent of roof space required. Because high-efficiency solar panels generate more energy per square metre, they need a less overall area to deliver the same output. Read about how solar works here.
For customers planning on an electric vehicle in the future, you’d want to leave as much space on the roof (by using the highest efficiency panels) for future expansion to charge electric vehicles. This is even more important when considering adding battery storage to your solar system in the future, as the additional available roof space leftover from using high-efficiency solar panels will provide extra roof space to install future panels allowing you to generate enough excess solar to charge the solar battery.
