How Long Do Solar Panels Last?

05 Jul How Long Do Solar Panels Last?

Solar energy has become a top contender in New England’s efforts toward sustainable energy sources. Solar panels, which use the sun’s abundant energy, have emerged as a vital element of the green revolution and a symbol of sustainable living. But for how much longer can we hope for these technological wonders? Discover the answer to the question: How long do solar panels endure? Let’s explore the intriguing world of solar panels.

The Invention of Solar Panels

We could go all the way back to 1839 for the discovery of the photovoltaic effect, but we have other blog posts for that. Let’s start with the creation of solar panels to comprehend their lifespan. Solar panels, invented in the 1950s, have advanced significantly in durability and efficiency. To counteract climate change and lessen reliance on fossil fuels, photovoltaic (PV) cells, primarily composed of silicon, gather sunlight and transform it into valuable electricity.

Estimated Lifespan

Solar panels are made to last, and their designers ensure they can survive various environmental factors. A properly maintained solar panel system can typically last 25 to 30 years. Although many solar panels continue to produce electricity well after this period, this estimate is cautious. Solar panels are incredibly long-lasting; some have been reported to produce electricity for over 40 years.

While the average lifespan is remarkable, several factors can affect how long solar panels last, including:

• A critical factor in influencing the panel’s lifespan is the quality of the materials utilized during manufacturing. High-quality solar panels with durable parts typically survive longer than their less expensive counterparts.
• Proper upkeep and maintenance significantly increase the lifespan of solar panels. Regular maintenance, inspection, and fast problem-solving can help guarantee maximum effectiveness and longevity.
• Solar panels are designed to resist a range of weather conditions. However, severe weather conditions like hurricanes or hailstorms pose a risk of panel damage. Harsh regions with excessive humidity or extreme temperatures may impact longevity.

Degradation and Power Output

Over time, solar panels go through a natural process of degradation called “power output degradation.” Most panels experience an annual efficiency loss of 0.5% to 1%, a relatively moderate decline. As a result, solar panels can continue to generate a large amount of electricity even after many years.
