Photovoltaic arrays convert sunlight to electricity with a typical conversion efficiency (range) of 10% to 30%.
A tree receives sunlight, and stores some of this solar energy as a hydrocarbon (wood). What intensity of sunlight is needed, over what area of leaf canopy, for how many hundreds of hours, for a tree to add 1 pound (dry weight) of wood to its mass? Or to add 1 cubic foot to its trunk+branch volume?
The answer may be specific to any tree species -- alder, hemlock, etc -- that grows in a temperate rainforest (i.e. Maritime Northwest U.S.).
