Japanese home and business owners with solar power installations sold 2,150 GWh of electricity back to their power utilities last year, a huge 50 percent increase over the amount sold back to the grid in 2010. The sellers collectively made a nice $1.2 billion off their surplus electricity.
The Japanese government has a feed-in-tariff scheme that requires the utilities to purchase the extra power which was small beans compared to the average 884,000 GWh of electricity that those utilities sell to customers per year.
The government is set to introduce even more subsidies for domestic renewable energy power developers. The new scheme will include electricity from solar, wind, small hydroelectric, biomass and geothermal plants, but only solar panel owners with systems of 10 kW or less will still be able to sell their excess power.
