The lifespan of solar panels, also known as the "operational life," can vary depending on various factors such as the quality of the panels, the manufacturer, the environmental conditions they are exposed to, and how well they are maintained. However, most solar panels are designed to be durable and have a long lifespan.
On average, modern solar panels are expected to last for 25 to 30 years or more. Many manufacturers provide warranties ranging from 20 to 25 years, guaranteeing that the panels will perform at a certain level during that period. It's important to note that while the performance of the panels may degrade slightly over time, they will continue to produce electricity beyond their warranty period.
With correct installation from a reputable business like Volta Green Energy, and regular maintenance, solar panels can continue to generate electricity well beyond their expected lifespan. In some cases, panels that were installed several decades ago are still functioning and producing power.
In general, reputable solar panel manufacturers design their products so they don't degrade further than a rate of around 0.5% to 0.8% per year. This means that after 25 years, the panels should still be operating at around 80% to 85% of their original capacity. Therefore, it is not uncommon for solar panels to last 25 to 30 years or even longer with proper maintenance.
Regular inspection, cleaning, and maintenance can help ensure the optimal performance and longevity of solar panels. It's also worth noting that solar panel technology continues to evolve, and newer panels may offer improved durability and longevity compared to older models.
It's worth mentioning that the inverters, which are a key component of solar PV systems, typically have a shorter lifespan of around 10 to 15 years and may need to be replaced during the lifetime of the panels.
Overall, investing in high-quality solar panels and ensuring proper maintenance can help maximize their lifespan and the return on your investment.
