Solar radiation decreases with increasing latitude. This is because the sunlight has to travel through more atmosphere at higher latitudes, which means more of the energy gets absorbed or scattered before it reaches the surface. Additionally, the angle at which the sunlight hits the surface becomes shallower as you move towards the poles, which means the same amount of energy is spread out over a larger area.
