Solar Panels: Longevity, Efficiency, and Environmental Impact
When it comes to solar panels, longevity, efficiency, and environmental impact are key considerations. Most solar panels boast a 25- to 30-year warranty, with a realistic lifespan extending from 25 to 40 years or more. Over time, solar panels experience gradual degradation, producing slightly less energy. Presently, industry standards indicate degradation rates between 0.1 and 0.8% per year, a figure steadily improving.
To estimate your panels’ output after a specific period, multiply the degradation rate by the number of years and subtract from 100%. For instance, with a 0.5% degradation rate, a 25-year-old panel will produce 87.5% of its initial output. As solar panels lack moving parts, they can endure for decades if undamaged by environmental factors.
Manufacturers provide equipment warranties against defects and performance warranties, often lasting 25 years, ensuring a specified electricity output. Remarkably, a solar panel’s 25- to 30-year lifespan surpasses its energy payback time (EPBT). EPBT signifies the duration required for a solar panel to generate enough clean energy to offset its manufacturing energy. Advances in technology have likely reduced the EPBT significantly, making solar panels even more environmentally friendly.
