testing

VDE Americas' David Devir looks at the origins of the supersized PV glass problem and considers how the industry can return to reliability.

Fraunhofer ISE has completed testing work of grid-forming inverters currently available in the energy industry.

The CEC has awarded a US$4 million grant to perovskite developer Tandem PV to test its perovskite-silicon tandem solar panels.

Lab-tested solar module performance has improved over the last year, according to data from US-based technical advisory firm RETC.

Eternal Sun has acquired German solar simulator provider Wavelabs, which has resulted in the formation of a new subsidy, Wavelabs Eternal Sun.

Inverters are critical to PV systems but are often over-specified due to inadequate data on which materials and designs optimise performance.

Fraunhofer ISE research suggests that the average monocrystalline silicon PV module’s power output was 1.2% lower than its nominal capacity.

A high breakage rate in thin PV module glass is a vulnerability that is not yet widely understood due to inadequate testing regimes, according to the IEA PVPS.

Wenzhong Shen, Sheng Ma and Huanpei Huang present an overview of the ultraviolet-induced degradation affecting TOPCon cells and modules.

Larger and thinner PV modules has contributed to increase breakages, although there is no single contributing factor, according to NREL.
