Understanding the Lifespan and Durability of Solar Panels

When it comes to investing in solar energy, one of the most common questions we hear is, “How long will my solar panels last?” It’s a valid question; after all, installing a solar panel system is a significant investment. Let’s delve into what you can expect in terms of the lifespan and durability of solar panels.

How Long Do Solar Panels Last?

Most solar panels come with a warranty of 25 years, but that doesn’t mean they stop working after that period. On the contrary, a well-maintained solar panel system can continue to generate electricity for 30 to 40 years or even longer. However, the efficiency of the panels — that is, their ability to convert sunlight into electricity — does decrease over time. The industry standard for solar panel degradation is about 0.5% to 1% per year. So even after 25 years, your panels could still be operating at around 80-90% of their original capacity.

How Durable Are Solar Panels?

Solar panels are designed to be very durable and can withstand a range of weather conditions, including rain, wind, and snow. They are constructed with robust materials like tempered glass and aluminum, which can resist damage from environmental factors. The majority of solar panels are tested to withstand hail of up to one inch falling at about 50 miles per hour.

However, while solar panels are built to be resilient, they’re not indestructible. Extreme weather conditions like hurricanes or tornadoes can cause damage. It’s also crucial to ensure proper installation to avoid issues like water leaks or roof damage.

Maintenance and Solar Panel Longevity

Proper maintenance can help prolong the lifespan of your solar panels. While solar panels don’t require a lot of upkeep, routine checks and cleaning can ensure they’re performing at their best.
