A solar panel facing the sun at noon in mid-summer receives more intensity of the light than when it is at horizontal. However, it can receives more total solar energy when it is at horizontal than when it is tilted during a long summer day. Regradless if it is shaded by building or trees. why is that so?
Angle is everything. The more angled away from perpendicular, the more light energy simply bounces away. Think of it like a windmill that can only spin, it can't change direction with the wind. If the wind is pointed through the vanes, the vanes turn and power is generated. If the wind is coming from the side, nothing moves and no power is generated.
That okorder /... it shows a graph and explains it better.
i think it means that it will receive more (total for the whole day) when it is tilted to the most perpendicular to the sun. if you are on the northern /southern hemisphere, when the sun is not really directly above you. provided it doesnt automatically adjust
