What is a power tolerance?
Power tolerance is a measure of how much electrical power a solar panel can produce above or below its rated capacity at any time. For example, a power tolerance of -5%/+5% on a 100-watt (W) panel would mean the panel could produce 95 W to 105 W under real-world conditions.
What is a 0% power tolerance?
For example, a power tolerance of -5%/+5% on a 100-watt (W) panel would mean the panel could produce 95 W to 105 W under real-world conditions. A 0% negative power tolerance means that the panel should always produce power equal to or greater than its rated power.
Why do solar panels have a smaller power tolerance range?
A smaller power tolerance range promises more accuracy. Power tolerance is specific to each solar panel product line, as mentioned in the respective product data sheet. Solar panels are sorted after manufacturing.
