What is a 500 watt solar panel?

A 500-watt solar panel has a wattage rating of 500 watts under Standard Test Conditions (STC). It has a daily and annual power output of around 2 kWh and 731 kWh respectively. It has module efficiency ratings of 21%. Typically, 500-watt panels are constructed from 144 half-cut monocrystalline cells.

What is a rated wattage solar panel?

1. Rated Wattage The wattage of a solar panel represents the electricity it generates under specific test conditions. These conditions include a solar irradiance of 1,000 watts per square meter, solar cell temperature of 25°C, and 1.5 air mass.

What are standard test conditions for solar panels?

Standard Test Conditions (STC) refer to the set of criteria under which a solar panel is tested. This includes a cell temperature of 25°C (77°F), light intensity of 1000 Watts per square meter (similar to noon sunlight), and an atmospheric density of 1.5 (sun’s angle perpendicular to the panel at 500 feet above sea level). 2.

How efficient are solar panels?

For example, if a panel receives 1,600 watts of sunlight on a 1.6 m² area with solar irradiation of 1,000 W/m², and it produces 355 watts of electricity, its efficiency is 22%. The best polycrystalline panels typically have around 17% efficiency, while the best monocrystalline panels exceed 22%.
