What Is A Solar Panel?
A solar panel, also known as a photovoltaic (PV) panel, is a device that converts sunlight into electricity. Solar panels are made up 1 of interconnected solar cells, which are typically made from silicon. When sunlight strikes the solar panel, the photons in the light knock electrons loose from the silicon atoms, creating an electric current. This process is known as the photovoltaic effect. Solar panels are a clean and renewable source of energy, and they can be used to power homes, businesses, and even entire communities. Solar panel longevity is a vital factor in their long-term value.
Understanding Solar Panel Lifespan
The typical lifespan of a solar panel is around 25-30 years. However, many solar panels can continue to generate electricity well beyond this timeframe, albeit often at a reduced efficiency. Solar panel longevity is influenced by several factors, which we will explore in detail. While the panels themselves can last a long time, other components of a solar system, such as inverters, may need replacement sooner. Therefore, when discussing solar panel longevity, it’s important to consider the entire system.
