What Happens to PV Panels When Their Life Cycle Ends
The energy industry has been experiencing a radical change and the gradual shift towards renewable energy sourcing is more than evident. Nevertheless, not all that looks sustainable stays that way upon the end of its life cycle. At least that is the most common worry regarding photovoltaic (PV) solar panels. They are a sustainable source of energy, dependant only on solar radiation, and capable of delivering electricity to our homes. However, what happens to solar panels when they fail to perform efficiently? Explore their journey through the recycling process in the infographic below:
The Lifetime of Solar Panels
How long do solar panels last? A question that most people have in mind when considering solar panels. According to studies, the life expectancy of solar panels is about 30 years before decommissioning.
During the life of photovoltaic panels, a 20 per cent decrease in power capacity might occur. Between the first 10 to 12 years, the maximum decrease in efficiency is 10 per cent, and 20 per cent when reaching 25 years. These figures are guaranteed by the majority of manufacturers.
Still, experience shows that, in reality, the efficiency drops by merely 6 to 8 per cent after 25 years. The lifespan of solar panels may thus be much longer than officially stated. The lifespan of high quality PV panels may even reach 30 to 40 years, and be still functional afterwards, though with decreasing efficacy.
