WebFeb 10, 2024 · To make a really crude estimate and avoid photometric vs radiometric units, the Sun provides a radiant flux of about 1400 W/m 2. If we assumed all of this was photons at 550 nm wavelength (definitely not true) and each photon (E = h*f/lambda) has an energy of 3.6 *10 -19 J, the photon flux would be 3.9*10 21 photons per second.
