Aren't they all sunny at the top of the atmosphere?

I assume that's very much latitude dependent

- gmm1990 3y agoshould be the same at all latitude
- laurencerowe 3y agoBut only if you point angle it towards the sun, so at 45 degrees latitude a 1x1m panel would take up 1x1.41m of ground area. There’s also more atmosphere in the way the further you go from the equator which will affect how much solar radiation reaches the earth. Overall only about half of solar radiation reaches the surface.
