For example if a 220w panel has a power tolerance of 10 10 the panel could have an actual max power of anywhere between 198 and 242w.
Positive power tolerance solar panels.
Does that sound unfair.
Power tolerance is a measure of how much electrical power a solar panel can produce above or below its rated capacity at any time.
As the technology behind solar panels continues to advance it s becoming more common for panels to have a 0 or 0w negative power tolerance.
3 power tolerance this is the range within which a panel manufacturer is saying the module can deviate from its specified stc max power.
Lg is quality focused solar panel manufacturer using a positive tolerance only grading system for their solar panels.
Many solar panel manufacturers use a plus minus tolerance normally shown in the panel specifications.
The importance of positive only tolerance.
If you had a 10 10 power tolerance on a 200w panel the actual panels on your roof could have actual max powers of between 180w and 220w.
For example a 255 watt panel may be tested as low as 250 watts but still sold as a 255 watt panel.
