What is the meaning of 500Wp in case of solar panels?

In case of a solar panel, 500Wp means 500 Watts peak (Wp), which is the maximum power it can produce under ideal standard test conditions. Typical ideal standard test conditions would mean solar irradiance or the intensity of sunlight of 1000W per square meter, photovoltaic cell temperature of 25°C and an air mass (AM) of 1.5g. The term 1.5g refers to AM1.5G solar spectrum, which is a standard for testing terrestrial solar cells.
