Cooling down solar modules by increasing space between panel rows

A US research team claims to have demonstrated that increasing the spacing of solar panels between rows improves PV system efficiency and economics by allowing airflow to cool down the modules. The method could improve a project's LCOE by as much as 2.15% in certain climates.A research group led by the US Department of Energy's National Renewable Energy Laboratory (NREL) has proposed a new approach to utilize connective heat transfer for solar module cooling in large-scale solar power plants. Their modeling considers factors such as row spacing, panel height, and tilt angle. It also uses a length ...
