Solar power is set to become profitable in Japan as early as this quarter, according to the Japan Renewable Energy Foundation (JREF), freeing it from the need for government subsidies and making it the last of the G7 economies where the technology has become economically viable.
Japan is now one of the world's four largest markets for solar panels and a large number of power plants are coming onstream, including two giant arrays over water in Kato City and a $1.1 billion solar farm being built on a salt field in Okayama, both west of Osaka.
"Solar has come of age in Japan and from now on will be replacing imported imported uranium and fossil fuels," said Tomas Kåberger, executive board chairman of JREF.

Japan is retiring nearly 2.4 gigawatts of expensive and polluting oil-fired energy plants by March next year and switching to alternative fuels. Japan's 43 nuclear reactors have been closed in the wake of the 2011 meltdown at the Fukushima power plant after an earthquake and a tsunami - since then, renewable energy capacity has tripled to 25 gigawatts, with solar accounting for more than 80 percent of that.
Once Japan reaches cost-revenue parity in solar energy, it will mean the technology is commercially viable in all G7 countries and 14 of the G20 economies, according to data from governments, industry and consumer groups.

"Just as shale extraction reconfigured oil and gas, no other technology is closer to transforming power markets than distributed and utility scale solar," said consultancy Wood Mackenzie, which has a focus on the oil and gas industry.
Oil major Exxon Mobil says that "solar capacity is expected to grow by more than 20 times from 2010 to 2040."
