How Long Do Solar Panels Last?

Is Your Solar Investment Long-Term? How Long Do Solar Panels Last? Here’s What You Need to Know!

There’s recently been a significant buzz about solar energy, especially in sun-drenched regions like Tampa. The benefits are undeniable: reduced energy bills, decreased carbon footprint, and the joy of harnessing the sun’s energy. But we often hear one question at Expert Solar: “How long do solar panels last?”

The Longevity of Solar Panels

Modern solar panels, often made of crystalline silicon, are built to last more than 25 years. Most manufacturers offer warranties that range from 25 to 30 years, but this doesn’t mean your panels will stop working after this period. Instead, it’s an assurance that by the 25th year, the efficiency of your solar panels will be around 80% of their initial capacity.

This is impressive! Think about it: your panels will still produce substantial energy after a quarter of a century. Beyond the warranty period, solar panels can continue operating for years, albeit with a slight dip in efficiency.

3 Factors Affecting Solar Panel Life-Span

It’s essential to note that while solar panels are designed for durability, several factors can influence their lifespan:

  1. Quality of Installation: Proper installation is crucial. At Expert Solar, we ensure a top-notch installation process to optimize panel longevity.
  2. Maintenance: Regular cleaning and maintenance can prolong the life of your panels. Dust and debris, if not checked, can reduce efficiency.
  3. Weather Conditions: Panels in Tampa are exposed to an abundance of sunlight, which is excellent. However, occasional storms can pose challenges. Choosing high-quality panels that can withstand these conditions is essential.

Invest with Confidence

Considering the long life span of solar panels, they’re an excellent long-term investment. Your initial setup cost spreads over many years of service, giving you an impressive return on investment.
