Solar Flash Tests or simulator tests are done to evaluate the output performance of a solar PV module. This test is performed by many manufacturers to find the operability of the PV module.
Power output flash testing measures the output performance of the solar PV module. The flash test machine or sun simulator is used to perform the test. In the flash test, the PV module is kept exposed to a short and bright light flash. the flash of light is usually 1ms to 30 ms in light of 100 mW per sq. cm. Usually, a xenon filled arc lamp is used in the procedure.
The output spectrum of the lamp is very high, in fact, it is close to the sun. The output is captured in the form of data and fed in a computer. The results of the test are compared to the PV module specifications that are written on the label of the module.
The test measures the module parameters. It is also called as the standard test conditions or STC. Temperature plays an important role in the performance of the PV module. When the temperature of a module is increased, the voltage output of the cell reduces, and the current output of the cell increases. This diminishes the maximum power output in Watt of the module.
The flash test is shared via the result sheet. It lists all the tested modules and their results. A reference PV module is often used in the flash test. It is a module of which the accurate power is determined by a certification body or a renowned testing lab.
Before the solar panels are sold in the market to the consumers, it must undergo a testing process. A test is important to ensure the power output it has. The makers first conduct a visual test of the solar panel. Then the flash test is done to measure its open-circuit voltage or VOC. Other things that are measured are voltage at maximum power point or VMP, short circuit current or ISC, current at maximum power point or Imp, and maximum power or Pm (W). even the fill factor or FF is measured through the Power output/flash testing.
These modules are measured using standard test conditions or STC. The STC sets the temperature at 25°C, the irradiance at 1000 W/m2, and air mass at 1.5 (AM1.5). When the PV modules are purchased, things like tier, experience, price, and deliverability are considered.
Solar panels have a long life. But with time, if you want Removing solar panels services, you can contact the solar panel removal service agents. Even solar energy contractors can do the installation and uninstallation. They can remove and reinstall the solar panels whenever you need it.
