The cost of photovoltaic generation is currently around NT $ 15-20 per kilowatt-hour (kWh), far above that of traditional power generation at NT $ 2.09 per kWh. But if in the future this cost can be reduced to NT $ 2.2, photovoltaic generation will become economically viable, and will also generate business for local industries.
雖然太陽光電的發電成本目前約為每度十五至二十元，比起傳統發電的每度二・○九元高出太多，但未來當降到二・二元時，就能符合經濟效益，還多了周邊產業效益。
