6 FAQs about [Solar power supply light irradiation principle diagram]
What is the difference between insolation/radiation (energy) and irradiance (power)?
Difference between insolation/radiation (Energy) and irradiance (power) Solar radiation is given in units of kWh per unit area per unit time
How does solar energy irradiation affect materials?
As depicted in Fig. 12 a, b, and c, there are primarily three distinct categories of solar energy irradiation effects on materials: the photoelectric response of semiconductors, the thermal effects by interaction with phonons across various material types, and plasmon excitation within metal particles or clusters.
How is solar irradiance distributed?
By the time sunlight reaches the earth, the rays are essentially parallel to one another, meaning that solar irradiance is distributed uniformly across a given surface area. Therefore, it is important that the light produced by your solar simulator is uniformly distributed across the "test area" used.
How does solar irradiance affect protection relays?
The daily variations in solar irradiance could also create reverse flows in sub-transmission networks that could cause the miss operation of protection relays. Limits established at the system level will usually be determined by the ability of generator control equipment to follow sharp variations in solar irradiance.

Here's a simplified explanation of the main components typically found in such a diagram :
How does sunlight produce electricity?
Sunlight is composed of photons (like energy accumulations), or particles of solar energy. These photons contain various amounts of energy corresponding to the different wavelengths of the solar spectrum. When photons hit a PV cell, they may be reflected or absorbed. Only the absorbed photons generate electricity.
