Simple take an irradiance sensor, turn it upside-down and test the
irradiance on the bottom surface of any PV array. It will vary greatly
based on exposure to reflected light and so on, but it will rarely be
above 100 W/m^2. 10% improvement is an absolute maximum for any bifacial
technology, and that is on the high side. Any claims above 10% are
ignoring the physics of sunlight, reflectance of typical materials, and
PV.</span></div><div class="yiv120406057MsoNormal"><span
