Taiwan's Ministry of Economic Affairs (MOEA) in December 2009 set feed-in tariff rates for photovoltaic (PV) system installation projects based on the estimate that such investment would be recovered in 10 years, but because costs for equipment of PV systems have fallen considerably and are expected to slip further, the time needed for return of all investment will decrease to eight years, according to MOEA.

MOEA are likely downward adjust the feed-in tariff rates for PV system installation projects to reflect the decrease in equipment cost, according to officials for Bureau of Energy under MOEA. However, the 2010 target total installation capacity of 64MWp under the feed-in tariff subsidization and the 2011 target of 70MWp remain unchanged, and there will be no caps on the total installation capacity in order to boost development of PV power generation, the officials pointed out. Thus, the target cumulative total installation capacity of 2,000MWp in 2025 may be reached earlier, the officials indicated.

MOEA has so far received applications for 825 PV system installation projects with total capacity of 134MWp and has approved 347 projects with 61MWp in terms of the qualification of power-generating equipment, the officials noted.
