Optimizing photovoltaic systems: Best practices for economic, technical key performance indicators
As the global solar energy industry grows, so does the need for accurate monitoring of performance and financial viability. The latest report by IEA PVPS Task 13, “Best Practice Guidelines for the Use of Economic and Technical KPIs,” provides a comprehensive framework to address this issue. This article explores the importance, methodologies, and applications of Key Performance Indicators (KPIs), with a focus on their role in optimizing PV systems.

IEA-PVPS shares guidance on technical KPIs for PV systems
The International Energy Agency’s (IEA) Photovoltaic Power Systems Programme (PVPS) highlights key performance indicators (KPIs) for PV systems in its latest report. It calls for clear KPI definitions and standardized data handling to enhance system efficiency and reliability.
Scientists develop thermal model for floating solar with 15.45% efficiency
Scientists have developed a multi-physics thermal model for panels with a natural convection cooling loop and tested it against experimental data. They have also experimented with varying the coolant channel thickness and different coolants. The highest measured electrical efficiency reached 15.45%.
UP: Steely determination
US-based Origami Solar has overcome two key challenges to replace aluminum solar module frames with steel products. The company says it can offer improved performance and a compelling value proposition, particularly for module makers setting up outside China. pv magazine caught up with Origami Solar CEO Gregg Patterson to discuss steel frames and the company’s expansion plans.
Testing rigid connectors in floating photovoltaics
New research from China shows that using rigid connectors instead of polyester ropes in floating photovoltaic arrays may help reduce the relative motion of floats and simplify the layout of the connection system.
