In 1950, photovoltaic power systems cost as much as $300. In 1970, when solar panels were not flourishing and the development of technology was not mature, not only the efficiency of solar panels is low, but also, the cost is high. Few people use, unless some special purposes, the price is even more prohibitive, about 100 dollars per watt.
