Sustainable photovoltaic technology development: step-by-step guidance for countries facing PV proliferation turmoil under the feed-in tariff scheme

In order to resolving climate change and energy security issues, one of the promising technology solutions is photovoltaic (PV). So far, the dominant policy measures and paradigm have been evolved from net-metering and/or investment grants to feed in tariff (FIT), renewable portfolio standards or tendering scheme. Of them, FIT promoted by the second comer of Germany has become the most successful and prevailing approach to promote PV around the globe. However, it also lead to the unexpected PV boom and over-development in most FIT countries and a lot of reform measures were introduced.
