The researchers found that placing reflective surfaces called “artificial ground reflectors” or highly reflective white surfaces beneath solar panels can increase energy generation and improve light absorption.

This straightforward adjustment resulted in a 4.5% increase in energy production.

One researcher in the team emphasized the importance of directly placing these reflectors beneath the solar panels to maximize their benefits, rather than placing them between train tracks.

This study on artificial ground reflectors is the beginning of a new research collaboration between the University of Ottawa and the National Renewable Energy Laboratory (NREL).

The ongoing research led by Mandy Lewis at the University of Ottawa holds promise for various locations worldwide, as 40% of the Earth’s land surface consists of sandy deserts, making this small-scale innovation beneficial for harnessing solar energy to its fullest potential in diverse regions.
