The Investability of PV Systems under Descending Feed-In Tariffs: Taiwan Case

The Taiwanese government has set an energy transition roadmap of 20% renewable supply by 2025, including a 20 GW installed PV capacity target, composed 8 rooftop and 12 ground-mounted systems. main trend feed-in tariffs is downwards, having fallen 50% over ten-year period. Predicting the future equity internal rate return (IRR) in this study, we examine investability systems Taiwan when subsidies investment costs descend. We have found that projected scheme favours small-sized Unless medium-sized fall or rise next decade, investing will be less attractive. Nonlinear linear degradation causes slight IRR differences using higher-reliability modules.
