Choice of solar panel conversion efficiency
Firstly, let's understand the concept of conversion efficiency. The conversion efficiency of solar panels refers to their ability to convert sunlight into usable electrical energy. It represents the percentage of solar radiation that is successfully converted into electricity from the absorbed energy.
Secondly, let's discuss the benefits of higher conversion efficiency. It's easy to grasp the concept that higher conversion efficiency results in a greater amount of electricity generated per unit area exposed to sunlight. More specifically, solar panels with the same power output will have smaller volume and weight, making them more portable and easier to install.
Taking the above points into consideration, it's evident that higher conversion efficiency is preferred when selecting solar panels. However, it's important to note that higher conversion efficiency typically comes with a higher cost.
Lastly, it's crucial to have a concept of the achievable conversion efficiency within the current technological capabilities to avoid falling victim to false claims made by unscrupulous businesses. Generally, there is a difference between the achievable efficiency in laboratory settings and that of commercially produced products. However, in recent years, this gap has been shrinking due to continuous technological advancements.
Currently, common solar cell conversion efficiencies range from 15% to 25%. Considering comprehensive cost factors, the upper limit of conversion efficiency for most commercially used solar panels is typically around 23-24%. Therefore, remember this number and make a reasonable choice based on your needs and budget.
