Solar Power: More than half of utility-scale solar photovoltaic systems track the sun through the day

Renewable Energy News - Wed, 04/26/2017 - 23:00

Because photovoltaic panels operate more efficiently when oriented directly at the sun, some systems use solar-tracking technology to increase electricity generation by rotating the panels along one or two axes.
