  • Research and development of energy self-consumption introducing photovoltaic and energy storage system at home is very active. This system can manage the home energy in which it charges the electricity generated during the day and uses it during high electricity bills. However, it not yet made up the residential real-time pricing in Korea but it can reduce electricity usage to a certain target on the progressive. In order to introduce the home photovoltaic, it requires PCS(Power Conditioning System). This converts the direct current into alternating current by the electricity generated and used to perform charging and discharging of the energy storage system. The market for self-consumption smart home system is currently increasing because the interests of the general public about solar power, energy storage systems increased.

The research results indicated that emotional value (in case of Korea) and functional value out of consumption values (in case of Germany) have significant effects in regards to the influence of consumption values on ethical self-identity. The effects of ethical self-identity on ethical fashion consumption behavior indicated that Korean ethical self-identity influenced the ethical fashion consumption behavior of moderating and simplicity and eco-friendly certification versus local consumption as well as above factors (in case of Germany) explained by ethical self-identity. Both variables had a negative moderating effect in Korea in regards to the moderating effects of social comparison and materialism in the relations of ethical self-identity and ethical fashion consumption behavior; however, only materialism was an influential factor in Germany. The results of the research variables by individualism/collectivism indicated that the horizontal-collectivism group showed the highest ethical self-identity along with the lowest materialism tendency that had a high point of consumption behavior towards local consumption.
