A solar array simulator is a programmable DC source that mimics the energy and power generated throughout daily solar cycles, as well as expected events such as eclipses. Simulating a solar array is practical for applications involving solar powered EUTs, as knowing the results of a cycling test is beneficial in the product development phase.
Solar array simulators come in various form factor and power capabilities, most often ranging up to 1500V and current that can be paralleled to 1000A and beyond. They are also programmable for the way the I-V curve changes throughout the day. A primary application is testing PV inverters that convert DC power generated from solar panels into AC power that can be transmitted via the grid.
ATEC has a selection of solar array simulators to rent from top manufacturers such as
Chroma,
Keysight, and more.
