Space contains varying levels of great electromagnetic radiation as well as ionizing radiation. There are 4 sources of radiations: the Earth''s radiation belts (also called Van Allen belts), galactic cosmic rays (GCR), solar wind and solar flares. The Van Allen belts and the solar wind contain mostly protons and electrons, while GCR are in majority very high energy protons, alpha particles and heavier ions. Solar panels will experie

Solar panels on spacecraft

Solar panels will experience efficiency degradation over time as a result of these types of radiation, but the degradation rate will depend strongly on the solar cell technology and on the location of the
