The Japanese refiner plans to spend as much as 160 billion yen ($1.7 billion) over five years to expand its solar business as domestic demand for oil products wanes. “The Saudi project is the first step in its solar expansion, and investors are bidding up” the shares on today's news, Hidetoshi Shioda, a senior analyst at Mizuho Securities Co., said by phone from Tokyo. “Showa Shell's shares haven't reflected the impact of its solar expansion as the business hasn't yielded a profit yet.” In May, Showa Shell announced plans to spend close to $2 billion over the next five years to expand production of solar equipment. Under the agreement, Saudi Aramco will work with Showa Shell on several projects with generating capacities of 1 megawatt (MW) to 2MW each - for a total of about 10MW. The projects will be in areas where there is currently no grid-supplied electricity. They will employ copper indium diselenide solar cell made by Showa Shell in Japan its factory in Miyazaki Prefecture.
