Frequently Asked Questions (FAQs)
What is the difference between STC and PTC ratings for solar panels?
STC (Standard Test Conditions) and PTC (PVUSA Test Conditions) are two different methods of rating solar panel performance. STC is a lab-based measurement that provides a consistent benchmark, while PTC is designed to better reflect real-world operating conditions. PTC ratings are generally lower than STC ratings and can provide a more realistic estimate of actual power output.
How does temperature affect solar panel performance?
Solar panel performance decreases as temperature increases. The temperature coefficient indicates how much a panel’s power output will decrease for each degree Celsius above the standard test temperature (25°C). A lower temperature coefficient is better.
What is the typical lifespan of a solar panel?
Most solar panels are designed to last for at least 25 years. Performance typically degrades gradually over time, but panels should continue to generate a significant amount of electricity well beyond the 25-year mark.
How much maintenance do solar panels require?
Solar panels require very little maintenance. Occasional cleaning to remove dirt and debris is usually sufficient. In areas with heavy snow or ice, it may be necessary to remove the accumulation to ensure optimal performance.
Will solar panels work on cloudy days?
Yes, solar panels will still generate electricity on cloudy days, although at a reduced rate. Even on overcast days, solar panels can produce a significant amount of power, especially with newer, more efficient panels.
