Estimated Peak Solar Radiation: Loading...

/ Data provided by NASA POWER Project. The first value represents the average solar radiation over a 24-hour period for the most recent available day in San Diego, California. It's derived from the daily total of all sky surface shortwave downward irradiance, converted from kWh/m²/day to W/m². The estimated peak value is calculated as approximately 4.5 times the daily average, representing the maximum solar radiation typically occurring at midday. Note that actual solar radiation varies significantly throughout the day, with zero values at night. This data helps in understanding the overall solar energy potential in the area.
