The Lifespan of Solar Panels: What to Expect
Solar panels generally last between 25-30 years, assuming proper installation and environmental conditions. A modern solar panel experiences minimal efficiency loss—about 0.2%-0.3% per year—which means you can expect sustained performance even after a couple of decades. Manufacturers base their lifecycle predictions on this degradation rate, thus, with quality brands like Project Solar offering lifetime warranties, you get peace of mind against performance dips (Solar Energy UK, 2023).
Monocrystalline panels usually outperform their polycrystalline counterparts in terms of longevity and efficiency. While both types often come with a standard 25-year warranty, monocrystalline panels are expected to last around 40 years compared to 35 years for polycrystalline. The investment may be costlier upfront, but for long-term savings and performance, monocrystalline panels prove worthwhile (American Solar Energy Society, 2023).
Choosing Between Monocrystalline and Polycrystalline Panels
Understanding Solar Panel Warranties
Warranties on solar panels often span 10-25 years, covering performance degradation. A typical performance warranty guarantees 90% electricity production at 10 years, dropping to about 80% by 25 years. Additionally, batteries and inverters—which also require attention—come with separate warranties ranging from 5-15 years, ensuring a comprehensive safety net for your investment (National Home Energy Survey, 2023).
Maximizing the Lifespan of Your Solar Panels
To prolong the life of solar panels, regular maintenance is crucial. This includes cleaning to remove debris, avoiding physical damage, and proper installation angles. Over time, neglect leads to reduced efficiency. Experts suggest performing periodic checks for wear and tear, as well as protecting panels from external threats, like pests. Utilizing our comparison tool can help you find reliable providers for installation and maintenance (European Union, 2023).
