Impact factors on SA output power.
| Impact factors | Main relevant influencing factors | The trend varying with the days of SA on-orbit | The relation to the output power |
| Solar sunlight intensity coefficient | The direction of the sun |
Trigonometric variation with a cycle of one year |
Impact factor determining the periodic change with a cycle of one year | Distance between the Earth and the Sun | Solar incident angle | Solar incident angle |
| Attenuation factor | Particle radiation | Exponential decay | Impact factor determining the attenuation along with the number of days of SA in orbit | Ultraviolet irradiation | Micro meteoroid collision | Alternating between cold and hot | Space pollution to SA |
