    I'm not an expert, but this is an area of pet interest.  There are many problems with solar (and other renewable) energy, problems that very large industry and lobbying groups with vast budgets have failed to resolve.  In Europe there is a great deal of solar energy but most (i.e. north of the med) its subsidised because the panels just aren't efficient enough and cost so much to produce. 

    For substantial applications they don't produce very useful current either, so you really have to either store energy for lighting (expensive batteries) or tie to the grid so that the network can use your trickle to offset a few rpm on a gas turbine elsewhere in the grid.
