Should solar panels be installed on snow-covered mountains?

The placement of solar panels on snow-covered mountains can boost the production of electricity when it is most needed — in the cold, dark winter. Solar-power systems have long been hampered by a seasonal problem: the panels produce more energy in summer than in winter, at least in the mid-latitudes, where much of the planet’s population lives.

Could thin air help fill winter solar-power gap?

Do solar panels produce more energy in winter?

Solar-power systems have long been hampered by a seasonal problem: the panels produce more energy in summer than in winter, at least in the mid-latitudes, where much of the planet’s population lives. To meet the goal of drawing 100% of energy from renewable sources, planners need to find ways to increase winter output.

Can solar power be installed in a snowbound area?

The state plans to set up a one-gigawatt solar power plant in the Spiti Valley, an area that typically sees more than 300 clear and sunny days in a year but remains snowbound for up to a third of the year. Installing solar power plants in snowbound areas offers an important avenue for reducing pollution and mitigating climate change.
