Solar has been the main beneficiary, accounting for 5.67GW, or 97% of the new renewables generation added between the introduction of the scheme in July 2012 and October 2013. The sector doubled virtually overnight, led by the explosion in non-residential PV, which leapt from a pre-FIT 900MW to 4.72GW.*
Historically, residential PV has comprised 80-90% of our national solar capacity. The sea of 3-5kW rooftop installations made Japan the odd man out in the international market, in which commercial-scale arrays dominate.
