Why do solar panels have a low voltage?

On cloudy days or when the sun is low in the sky, solar panels receive less sunlight, leading to reduced voltage output. Solar panels should ideally be installed in locations free from shading. Shadows cast on the panel can significantly reduce its voltage output, as the shaded cells will produce less electricity than those exposed to sunlight.
