* Watts (W): A unit of power, which is the rate at which energy is used or produced.
* Solar Panel: A device that converts sunlight into electricity.
What does "ideal conditions" mean?
* Full Sunlight: The panel needs to be directly facing the sun at a 90-degree angle (known as "peak sun").
* No Clouds: Clouds block sunlight, reducing the panel's output.
* Standard Test Conditions (STC): The panel is tested under laboratory conditions with a specific air temperature, solar irradiance (amount of sunlight), and cell temperature.
Factors that affect actual power output:
* Time of Day: The angle of the sun changes throughout the day, affecting the amount of sunlight hitting the panel.
* Season: Solar panels produce more power in the summer when there's more direct sunlight.
* Weather: Clouds, rain, and snow can significantly reduce output.
* Panel Angle: The angle of the panel needs to be optimized for the location's latitude to maximize sunlight absorption.
In short, a 250 watt panel is a measure of its potential power output, but the actual amount of power generated will vary depending on the conditions.
