Large Area Solar Simulator

Test reliability of PV modules in a controlled environment

a solar simulator in a lab

The Large Area Solar Simulator (LASS) produces class AAA+ (according to the IEC 60904-9 ed. 3), steady-state sunlight using a unique and patented technology.

Its positioning is highly flexible and results in a small footprint making it easy to use and ideal for all PV technologies and for all illumination tests from the IEC 61215  and IEC 61730.

For solar module testing purposes, user-friendly IV-measurement equipment is provided with the solar simulation system.

A temperature control chamber can be added.

installation of Perovskite PV modules

Accurately test the efficiency and reliability of Perovskite and Tandem PV modules

A class steady-state illumination, adjustable spectrum and light stability enables precise measurements of these innovative technologies
