A Solar Sun Simulator is the basic device to categorise photonic properties. The primary objective of this technology is to provide illumination of natural sunlight to manage indoor test facility inside a lab. The simulator is used to fake sunlight in a lab setting. Its light source is designed to produce spectral composition and similar intensity of natural sunlight.

Different types of Solar Sun Simulators

A Solar Sun Simulator is of two categories:

  • Flashed/Pulsed Simulators – Unlike the steady state, these simulators have not constant light source. They are used to stop heat build-up in the examined device generated by a lamp light source. Users can turn on and off Pulsed Sun Simulators to have not constant light source or use a shutter to block the light source.
  • Steady/Continuous Simulators – Continuous Simulators have a steady source of light. The Steady Simulators are used in smaller areas for low-intensity testing.

Features of Flashed Solar Sun Simulators

Pulsed Simulators are highly useful. Here are some significant features of Flashed Simulators:

  • Designed to illuminate large photovoltaic devices
  • Prevent heat build-up
  • Allow users to use a shutter to stop the light coming from a source 

Features of Steady Solar Sun Simulators

Continuous Simulators are known for their different features and functions. Here are some of them:

  • Designed for light-soaking testing and hot-spot endurance testing
  • Ensures stability of intensity
  • Tracks temperatures, intensity, and allied parameters
  • Ideal for array or single panel testing
  • Specialised continuous switching light source
