Degradation Rate
Degradation Rate refers to how quickly solar panels lose their ability to produce power over time. Think of it like how a phone battery becomes less effective as it gets older. When someone mentions degradation rate in their resume, they're talking about their experience in measuring, analyzing, or improving how well solar panels maintain their performance over many years. This is crucial because solar panels are a long-term investment, and companies want them to work efficiently for 25-30 years. A typical degradation rate is about 0.5-1% per year, meaning a panel might produce slightly less electricity each year.

Example Interview Questions
Senior Level Questions
Q: How would you develop a long-term strategy for monitoring solar panel degradation across a large solar farm?
Expected Answer: A strong answer should discuss creating systematic monitoring programs, using data analysis tools, considering environmental factors, and implementing preventive maintenance schedules.
Q: What methods would you use to predict the financial impact of degradation rates on a 25-year solar project?
Expected Answer: Look for answers that include understanding of financial modeling, real-world performance data, and ability to consider multiple factors like climate, installation quality, and maintenance practices.
Mid Level Questions
Q: What factors can affect solar panel degradation rates?
Expected Answer: Should mention weather conditions, temperature cycles, installation quality, panel type, and maintenance practices as key factors affecting degradation.
Q: How do you measure degradation rate in the field?
Expected Answer: Should explain basic monitoring equipment, data collection methods, and comparison of current vs. initial performance measurements.
Junior Level Questions
Q: What is a typical degradation rate for quality solar panels?
Expected Answer: Should know that quality solar panels typically degrade at 0.5-1% per year and understand this is an important benchmark in the industry.
Q: How do you calculate simple degradation rate?
Expected Answer: Should be able to explain the basic concept of comparing current power output to initial output and expressing the difference as a percentage.
