Understanding Solar Panel Degradation and Why It Matters
Overview
Solar panel degradation is an important factor to consider when investing in solar energy. Over time, all panels experience a gradual decline in performance, which affects the amount of electricity they produce. This reduction, known as the degradation rate, directly impacts long-term savings, energy output, and overall return on investment.
Massachusetts homeowners and businesses, in particular, should be aware of these rates due to the state’s high electricity costs and commitment to renewable energy. Choosing panels with a low degradation rate, like REC’s Alpha Pure RX panels, can make a significant difference in energy production over time. At Spectrum Energy, we’re proud to offer these industry-leading panels to maximize the value of your solar investment.
What Is Solar Panel Degradation?
Solar panel degradation refers to the slow reduction in a panel’s ability to convert sunlight into electricity. This is a natural part of aging for all solar panels, but the rate at which it occurs can vary significantly based on the panel’s quality and construction.
The industry average degradation rate is 0.4% to 0.5% annually, with some lower-quality panels degrading as much as 0.6% per year. For a typical solar system, this means losing 10-15% of its efficiency over 25 years. However, premium panels like REC’s Alpha Pure RX degrade at just 0.25% annually, retaining 92% of their original performance after 25 years. This makes REC panels a standout choice for those looking to maximize long-term energy production and savings.
Why Solar Panel Degradation Rates Matter
At first glance, a difference of 0.25% versus 0.5% may not seem like much. But when you consider the cumulative effect of degradation over decades, the impact on energy output becomes significant. A lower degradation rate ensures your panels produce more power over their lifetime, which translates into higher savings and a better return on your investment.
In addition to financial benefits, low-degradation panels reduce environmental waste by maintaining performance longer, eliminating the need for early replacements.
Causes of Solar Panel Degradation
Solar panel degradation occurs due to a variety of factors, including:
Environmental Stressors: Over time, constant exposure to sunlight, extreme temperatures, and weather events can cause wear and tear on the panel’s materials.
Material Quality: Panels made with inferior materials degrade faster, while premium materials, like those used in REC Alpha Pure RX panels, resist environmental damage more effectively.
Manufacturing Standards: Panels manufactured with advanced technology and rigorous quality control tend to degrade at a slower rate, ensuring better long-term performance.
The Advantage of Low-Degradation Panels Like REC Alpha Pure RX
One of the biggest benefits of choosing REC Alpha Pure RX panels is their exceptionally low degradation rate of just 0.25% annually, compared to the industry average of 0.4% to 0.5%. Let’s look at how this difference affects energy production over 25 years for a typical system.
Example: Comparing Energy Output Over 25 Years
Imagine a solar system producing 10,000 kWh in year one:
System with 0.25% Degradation Rate:
After 25 years, this system would produce approximately 231,594 kWh.
System with 0.5% Degradation Rate:
After 25 years, this system would produce approximately 218,750 kWh.
The Difference
The REC system produces an additional 12,844 kWh over 25 years.
At an average Massachusetts electricity rate of $0.33/kWh, this translates to $4,238 in extra savings from REC’s low degradation rate.
This example demonstrates how a small difference in degradation rates can have a major impact on your energy production and financial returns over the lifetime of your solar system.
Comparing Solar Panel Warranties and Long-Term Performance
When choosing solar panels, it’s essential to look beyond the upfront cost and consider long-term performance and warranty coverage. A strong warranty reflects the manufacturer’s confidence in their product and provides peace of mind for the buyer.
REC Alpha Pure RX panels are backed by an industry-leading 25-year product and performance warranty, guaranteeing they will retain at least 92% of their original output after 25 years. In contrast, panels with higher degradation rates often have lower performance guarantees, meaning less energy production and fewer savings over time.
