Solar shingles, also called photovoltaic shingles, are solar cells designed to look like conventional asphalt shingles. There are several varieties of solar shingles, including shingle-sized solid panels that take the place of a number of conventional shingles in a strip, semi-rigid designs containing several silicon solar cells that are sized more like conventional shingles, and newer systems using various thin film solar cell technologies that match conventional shingles both in size and flexibility. Solar shingles are manufactured by companies including SunPower Corporation, Solar Components Corporation, Atlantis Energy Systems, and Dow Chemical.[1]
perhaps... part of the role of some appropriates technologies are to be used in developed nations.
appropriate technologies, if this writer's understanding is correct, is that ... they can potentially help decrease the amount of poverty in an area quite efficiently... at least perhaps... they can potentially help to raise the standard of living and quality of life in an "impoverished" area quite efficiently...
but also... in more developed nations, where "problems" are different....
perhaps solar shingles... could be a way to marketably decrease wealthy nations dependance on other nations..........
