Why are solar panels less efficient in a heatwave?
Clouds and haze: Less sunlight reaching the panels means lower power output. Heat: High temperatures reduce panel efficiency. In a heatwave, solar panels can reach 65 degrees and this can reduce power by 20% compared to panels that are at 25 degrees. Wind: While sunshine heats panels a nice breeze helps cool them down.
What’s the name of the company that installs solar panels?
