Answer
Most solar radiation is delivered at wavelengths that are unsuitable for photosynthesis. Pigment molecules like chlorophyll absorb all wavelengths of visible light besides green, so efficiency is further reduced. Additionally, a portion of radiation is reflected from the earth's surface and never makes its way to plants.
