It seems quite a few years ago you could get Solar Voltaic Cells incredibly cheap. Now it seems that they are everywhere PLUS coupled with the fact of 'green initiatives' the cost of acquiring them is much more. I do not feel this price increase is pure inflation. Is it only me that feels because of the new-found 'popularity' or requirements to use these units that have driven up the costs, or is it some other factors (e.g. new technology, incredibly high demand, rare material etc.)?
