Investing in solar power for your commercial property is a smart move toward sustainability and cost savings. One thing to consider as you make the change to solar is “How long will these solar panels last?” Understanding the lifespan of solar panels and their long-term value is essential in considering your overall investment and financial savings. While a variety of factors influence their durability, including climate, installation quality, and maintenance, the benefits of solar panels extend well beyond their years of operation. Learn more about how long solar panels last on your commercial property:
The Average Lifespan of Solar Panels
Solar panels are built to last. According to EnergySage, solar panels last 25 to 30 years on average. This doesn’t mean they stop working altogether after this period, but their efficiency in converting sunlight into electricity begins to decline, typically around 0.5% per year. By the 25-year mark, many panels still operate at about 80% of their original efficiency.
High-quality panels often outperform expectations. It’s essential to factor in the type of solar panels you’re investing in. Monocrystalline panels, for instance, tend to offer higher efficiency and longevity compared to polycrystalline panels, though their upfront cost is higher.
Factors That Affect Solar Panel Lifespan
The actual lifespan of your solar energy system depends on a combination of factors, including climate, installation, and maintenance.
Climate
Solar panels are designed to withstand harsh conditions, from scorching heat to heavy snow. However, extreme weather can impact their longevity over time. Hailstorms or heavy winds may damage panels if exposed too frequently. At the same time, panels in environments with mild, predictable weather might perform optimally for many years.
In Arizona, solar panels are uniquely positioned to work efficiently, with 300 sunny days per year.
Type of Installation
Proper installation is critical for durability. Roof-mounted systems and ground-mounted systems have their pros and cons, but poorly-installed panels are more likely to sustain damage or degrade faster.
Regular Maintenance
Maintenance is another factor that significantly impacts solar panel longevity. While panels require little upkeep overall, regularly cleaning them to remove dirt and debris ensures optimal sunlight absorption. Periodic inspections by professionals can also identify wear and tear before it becomes a significant issue. Keeping your system’s inverters, wiring, and mounting structure in good condition further ensures long-term reliability.
Financial Savings Over Time
Even with a lifespan of 25 to 30 years, solar panels can deliver immense financial benefits for commercial property owners. These savings begin immediately with reduced electricity bills. Over time, the panels essentially pay for themselves, typically within the first five to 10 years of operation, depending on your system's size, energy usage, and local energy rates. That leaves you with decades of nearly “free” energy to power your business.
Some businesses also qualify for tax incentives, rebates, and credits, further increasing the value of going solar. While there’s an upfront investment, the return on investment (ROI) for solar panels is incredibly compelling. By shielding your business from the unpredictability of traditional energy costs, solar power offers long-term certainty in your utility expenses.
Recycling Solar Panels After Their Lifespan
Solar panels are highly recyclable. Most panels are made primarily of glass, aluminum, and silicon, with a small number of metals like copper or silver. These materials can be extracted and reused in the creation of new panels or other products. There’s a growing industry around solar panel recycling, with facilities dedicated to breaking down and repurposing old components.
Recycling panels reduces environmental impact, ensuring solar technology remains a sustainable energy solution. By choosing solar, you’re not just saving money or reducing carbon emissions during operation; you’re also contributing to the circular economy at the end of the system’s life.
The Benefits of Solar Panels Outweigh the Lifespan Limitations
Regardless of their lifespan, solar panels are an undeniably smart investment for commercial properties. They offer significant financial savings, support corporate sustainability goals, and enhance a property’s value. The energy independence they provide protects businesses from volatile energy markets, while tax breaks and incentives sweeten the deal. These benefits far outweigh the need for maintenance or eventual replacement.
And even when their efficiency declines, solar panels still produce considerable energy. They can supplement your building’s power needs for decades before recycling becomes necessary.
