Keysight N8937APV Photovoltaic Array Simulator, 1500 VDC, 208
VAC from Axiom Test Equipment
May 3, 2022 - Vista, California - Axiom Test Equipment, Inc., an electronic test equipment rental
and sales company has published a new blog post on
Solar Power Testing. PV technology is gaining wider acceptance,
as it is providing electricity for everything from wearable medical devices to large
manufacturing facilities. In this post we explain how with the right power supplies
for simulation and well-equipped analyzers for investigation, a future with solar
power sources such as PV cells, modules, and arrays is closer than we think.
Test equipment for PV cells, modules, panels, and arrays should be capable of
performing the types of measurements that typically characterize such PV components
and systems, including short-circuit current testing and open-circuit voltage testing,
Additional PV measurement capabilities include solar responsivity or how a PV device
responds to different wavelengths of light and how efficiently it can convert light
to electricity. Useful test equipment capabilities include wide I and V measurement
ranges, high AC and DC power accuracy, and high resolution. For controlling DC power
levels at various points along a PV system, including at the input to the inverter,
auto ranging DC power supplies such as the Keysight N8900 Series provide high resolution
and accuracy across wide voltage and current ranges.
Axiom helps provide the best measurement solution for a particular PV system
based on the operating conditions. Learn more about the unit that best fits your

Shed Some Light on Solar Power Testing
When Michael Faraday generated electricity in 1831 by moving a magnet within
a coil of wire, he probably never imagined that sunlight could do the same thing.
Electromagnetic (EM) turbines powered by fossil fuels may still be the world’s leading
sources of electricity, but solar power based on photovoltaic (PV) energy is coming
on strong. It is dependable and economical. However, testing PV electricity sources
may pose new challenges for engineers and technicians “raised” on traditional electric
power supplies. But with the right power supplies for simulation and well-equipped
analyzers for investigation, a future with solar power sources such as PV cells,
modules, and arrays looks bright.
Henrich Hertz discovered the photoelectric effect in 1887. He learned that sunlight
could discharge electrons in certain materials, causing current to flow at some
voltage. It was not until 1954 that a practical PV cell was created at Bell Labs
(Berkeley Heights, NJ) by the team of Daryl Chapin, Calvin Fuller, and Gerald Pearson.
It converted sunlight to electricity with about 6% efficiency. The efficiency improves
with time, as modern PV cells provide conversion efficiency closer to 20%.
Arrays formed of many solar cells are often seen on the outsides of satellites,
where exposure to the sun provides electricity in space. Meanwhile, PV technology
is gaining wider acceptance back on Earth, as PV cells, modules, panels, and arrays
are providing electricity for everything from wearable medical devices to large
manufacturing facilities. Although solar electric sources produce electricity that
must be measured, testing the electricity is not quite the same as testing from
EM-based electric power sources. For one thing, conversion efficiency from sunlight
to electricity must be gauged for PV power sources under different conditions. Many
variables can affect PV conversion efficiency, but regional and global standards
define the test conditions required for testing solar power devices and systems
as needed for different applications.
