LED solar simulator stand-alone solar simulator head

For integration into existing or custom systems

Overview | Specifications | Gallery | Software | Resources and Support

The most cost-effective way to buy the Ossila LED Solar Simulator Lamp, the stand-alone solar simulator head is the same part as the one sold with the full product package and solar simulator I-V test system bundles. By offering the Ossila LED Solar Simulator Lamp without the z-stage or breadboard, we can provide the same technical features at a much lower price. This is ideal if you would like to add a solar simulator to your existing set up or custom system and have no need for the additional hardware that comes with the full product package.

Identical to the LED solar simulator head sold with the adjustable height z-stage or Solar Cell I-V System, the stand-alone solar simulator lamp unit is class AAA over a 15 mm diameter circular area (using the latest IEC 60904-9:2020 International Standard). The lamp is suitable for use over larger areas too, with a class B spatial non-uniformity rating for areas up to 25 mm in diameter and a class C rating for diameters up to 32 mm.

LED solar simulators offer several advantages over arc lamp solar simulators. They are cheap to run thanks to the high efficiency of LED lights and require zero maintenance. Arc lamps, by comparison, waste a considerable amount of energy as heat and need at least 30 minutes to warm up. The Ossila LED Solar Simulator Lamp is ready to use just a few minutes after you first turn it on.

Why Should You Buy the Ossila LED Solar Simulator Lamp?

The Ossila LED Solar Simulator Lamp offers great value and excellent quality. To achieve this, we use an array of powerful LEDs to accurately simulate the AM1.5G spectrum over a wavelength of 350 – 1050 nm. Furthermore, through our free, downloadable software, you have the ability to control the intensity of each individual LED. This gives you maximum control over the output of your Solar Simulator Lamp.

LED Solar Simulator Lamp Features

Wide UV-Vis-NIR spectral range

LED Lamp

The Ossila Solar Simulator uses light-emitting diodes to generate its light output. The advantages of LEDs over arc-lamp or incandescent alternatives include:

  • High efficiency
  • Long operating lifetime
  • High temporal stability
  • Zero maintenance
  • Spectral tunability
  • Virtually zero warm-up time
  • Ozone-free
  • No explosion risk

These many advantages of LED light sources result in a solar simulator that can reliably and accurately reproduce the solar spectrum.

Easy-to-Use Software

Easy-to-Use Software

There is no special programming or set up needed for the Ossila Solar Simulator to deliver dependable, high-quality solar irradiance. In most cases, all you need to do is plug it in and turn it on. By default, the lamp will deliver a calibrated output optimized to meet the solar spectrum.

However, our free, downloadable software allows you to control the LED outputs individually as well as change the total irradiance output. You can also control the lamp using a serial command library. This can be useful for specialist measurements or non-conventional spectral output (e.g. indoor PV measurement, low light intensity conditions, etc).

How to Set Up Your Solar Simulator Light Source

The Ossila Solar Simulator is available in two configurations. The automated set up which uses the automated Ossila Solar Cell I-V Test System with a fitted test board. It can also be configured using the manual test board in combination with the Ossila Source Measure Unit. This guide details how to assemble the manual Ossila Solar Simulator.

The Solar Spectrum The Solar Spectrum

The purpose of a solar simulator is to recreate the sunlight received on Earth. This is easier said than done as sunlight starts its journey in complex nuclear reactions in the sun's core, and is modified on it's journey to us through interactions with the Earth's atmosphere.
