CPVs, or concentrated photovoltaics, use lenses or mirrors to concentrate sunlight onto small, high-efficiency solar cells. This concentrated sunlight produces a higher voltage and current output, which is then converted into electrical energy.
The efficiency of CPVs can reach up to 41%, which is much higher than the average efficiency of traditional solar panels, which is around 15-20%. This means that CPVs can generate more electricity from the same amount of sunlight.
CPVs are typically used in large-scale solar power plants due to their high efficiency and cost. However, there are CPV systems designed for residential and commercial use, although they may not be as efficient as those used in power plants.
The lifespan of CPVs is similar to traditional solar panels, which is around 25-30 years. However, CPVs may require more maintenance due to their concentration technology, which can be affected by weather and debris.
CPVs have a higher efficiency compared to other renewable energy sources such as wind or hydro power. However, their cost and maintenance requirements may make them less viable in certain situations. It is important to consider the specific needs and resources of a location when choosing a renewable energy source.
