Again according to NASA, the worldwide daily average value of solar irradiance across the whole planet over one day is approximately equal to 5.0 kWh/m 2 or 5 peak sun hours (PSH). Photovoltaic (PV) panels convert solar irradiance into electricity.
A peak sun hour (PSH) is one hour of sunlight at an intensity of 1,000 W/m² (the standard test condition for solar panels). Daily PSH is the total solar energy received in kWh/m² divided by 1 kW/m². Example: 5.5 kWh/m²/day ≈ 5.5 peak sun hours. Irradiance is the power of sunlight hitting a surface (W/m²).
Solar irradiation is defined as the measure of solar radiation energy received at a particular location during a specified time period, commonly expressed as average irradiance in kilowatt-hour per square meter per day (kWh/m² per day). How useful is this definition? You might find these chapters and articles relevant to this topic.
Thus at an equatorial location on a clear day around solar noon, the amount of solar radiation measured is around 1000 watts, that is 1000W/m 2 (or 1.0 kW/m 2). When dealing with photovoltaic solar panels purely for the generation of solar power, a solar irradiance light level of 1.0 kW/m 2 is known as one “Full Sun”, or commonly “Peak Sun”.
