JPEA is promoting the growth and sound development of the PV industry in Japan. Our recent efforts have included establishing a certification system for PV installers aimed at developing skilled technicians to increase quality and consumer peace of mind. We are setting up maintenance and service guidelines to ensure stable power generation over the long term, and seeking to improve the connectivity of the electricity grid as more PV systems come on-stream. And, as PV systems expand and approach grid parity, our focus will continue to be on advancing its public recognition. We also promote the use of a broad range of PV-associated technologies. As a distributed power generation source, PV systems offer an opportunity to harness the benefits of energy management systems (EMS), a technology finding its way into homes, buildings and factories.
There is a renewed push in Japan to address its energy challenges. The energy situation has changed considerably, not only because of global warming, but also as a result of the Great East Japan Earthquake of 2011. This has led to a review of Japan's medium to long-term energy policy, with a focus on safety, stability, efficiency, and ecology. And, within the renewable energy agenda at the heart of this review, solar energy has a key role to play.
Solar energy has significant potential to achieving a low-carbon society. Since the government introduced the feed-in tariff scheme in June 2012, Japan has seen a remarkable increase in installations of photovoltaic (PV) systems. These have ranged in scale, from residential rooftop systems with the capacity of a few kilowatts, to large 'mega-solar' PV power plants with an output of several megawatts. While there are still hurdles to be overcome before PV systems are more widely adopted, there is immense opportunity.
