Homes all across Florida are taking advantage of the state’s endless sunshine by installing solar panels. Solar power is an environmentally friendly option that offers impressive energy efficiency.
Unfortunately, even the best solar systems won’t last forever. As your solar panels age, they gradually lose their efficiency.
Various factors cause degradation of solar panel efficiency over time. When you need services for your Orlando, FL, residential solar panels, PES Solar can help you restore your solar power.
What Is the Average Life Expectancy for Solar Panels?
The life expectancy of solar panels depends on various factors, but the average lifespan is about 25 years. The first 25 to 30 years of your panels’ life are known as their “useful life.”
After about ten years, solar panels gradually lose efficiency and produce less electricity. The gradual loss in electricity production is known as the degradation rate.
Although solar panels’ useful life ends around 30 years, they can continue to produce electricity for up to 60 years, just at a lower efficiency rate.
Due to degradation, warranties for solar panels tend to change as they age. For example, most manufacturers guarantee about 90% of solar panels’ production within the first decade. After that, they drop the guaranteed percentage to 80.
What Causes Solar Panel Degradation?
Solar power degradation is the result of two main factors:
Unfortunately, neither of these factors is controllable. Aging is inevitable, and you will likely need to replace your solar panels at the end of their working life. Weather is unpredictable and can impact your solar panels in various ways.
One of the most common weather-related problems facing solar panels is wind. Strong winds can force the panels to flex and cause potential damage. The best protection for solar panels against the wind is professional and high-quality installation.
Extreme changes in weather also impacts solar panel efficiency over time. Snow, ice, extreme heat, and humidity cause panels to expand and contract, which can cause tiny micro-cracks. Since UV rays are especially harmful, many solar panel manufacturers use UV blockers to protect the panels and improve their durability.
How Can I Improve Solar Panel Efficiency Over Time?
The best way to improve the efficiency of your solar panels is to start with a professional installation service. Since solar panels lack moving parts, little maintenance is necessary after installation. The best way to ensure that you achieve maximum solar power efficiency over time is to hire a trusted and experienced solar power company in Orlando, Florida.
