Solar irradiance is the power per unit area (surface power density) received from the sun in the form of electromagnetic radiation. In simpler terms, it's how much solar power is shining down on a specific area at a given time. Normal radiation levels for solar panels and photovoltaic systems can be categorized into various parameters, including sunlight intensity, radiation absorption rates, and external environmental factors. Solar. . Solar irradiation varies dramatically by location: Desert regions like the Sahara and Atacama can receive over 2,800 kWh/m²/year, while northern European locations may only receive 800-1,200 kWh/m²/year. This 3-4x difference directly impacts system sizing, energy production, and economic viability. . Electromagnetic radiation refers to the process by which electromagnetic waves spread outward in the form of waves. These waves include radio waves, microwaves, infrared, visible light, ultraviolet rays, X-rays, gamma rays, and more, spanning a wide range of frequencies from low to high. For more information on NLR's solar resource data development, see the National Solar Radiation Database (NSRDB).
