Measuring efficiency of photovoltaic panels takes into account the maximum amount of energy that can be recovered for a given amount of sunlight (a theoretical max of about 1kw/m^2). So 20% efficiency implies that 20% of the total energy that hits a given area of panel is converted to electrical energy (the rest is presumably reflected off or converted to heat). Whether the area is 2 or 3 dimensional is irrelevant; any upper layer will necessarily result in diminished energy passed to the lower layers.
- fuzzfactor 2y agoDoesn't seem like you would abide with any exaggeration at all ;) What I would really like to see is their lab, to find out if I think they have the necessary instruments to make proper measurements. If not then I would want to find out how their measurements were taken. If so then I would like to see some real-time measurements myself. When you see a single sphere resting upon a large rectangular pedestal like that, it's always possible there is a battery under there being charged by solar energy. Equally possible I guess that there's a battery under there powering the sphere instead. Similar odds it could also be a rehash of futuristic 1960's technology, if each sphere contains a rare dilithium crystal from the original Starship Enterprise ;)
