"This econometric study covers the latent demand outlook for photovoltaic (PV) modules across the prefectures and cities of Japan. Latent demand (in millions of U.S. dollars), or potential industry earnings (P.I.E.) estimates are given across some 1,000 cities in Japan. For each city in question, the percent share the city is of it's prefecture and of Japan is reported. These comparative benchmarks allow the reader to quickly gauge a city vis-a-vis others."
