This paper describes the political and technical trends of foreign 10 countries advanced in solar energy field. In the trend analysis, a couple of statistical data and related references were compared. As a result, all of the advanced countries mentioned in this paper have their own PV policy strategies and regulatory frameworks to strengthen their stable market structures and have financially supported by various types of incentives and tariff systems. It was confirmed that the political basis and technical regulations including electrical safety have to be prepared as soon as possible at both national and rural level in this country.
