Household attributes and electricity consumption of photo-voltaic-system owners and non-owners are investigated by using an internet questionnaire.It was found that the photo-voltaic-system owners have higher income and try to conserve energy more positively than the non-owners. The photo-voltaic-system owners positively invest in solar water heaters, insulated walls, double windows, and LED bulbs. Installed capacity of the majority of the photo-voltaic-systems ranges 3 to 4 kW. Most of the owners introduce the photovoltaic systems for the purpose of saving money on electricity when they build or rebuild their house.The electricity consumption in summer shows a statistically significant difference between the photo-voltaic-system owners and non-owners while the electricity consumptionin winter doesn't.
