What is Solar Panel Efficiency

Solar panel efficiency refers to the amount of energy from the sun that a solar panel can convert into usable electricity. It is typically measured as a percentage of the total energy from the sun that falls on a solar panel and is converted into usable electricity.

For example, if a solar panel has an efficiency rating of 20%, it means that 20% of the energy from the sun that falls on the panel is converted into usable electricity, while the remaining 80% is lost as heat or reflected back into space.

Efficiency is an important factor to consider when choosing a solar panel because it determines how much electricity the panel can generate for a given amount of sunlight. Higher efficiency panels can generate more electricity per unit of area, which can be beneficial for installations with limited roof space or other areas where space is a premium.

Overall, solar panel efficiency is influenced by several factors, including the type of solar cell technology used, the quality of the materials and manufacturing processes, and environmental conditions such as temperature and sunlight intensity.
