After several decades of gradual progress, the photovoltaics (PV) is reaching the economical feasibility and various incentives for its development are being cut. The most successful incentive - the feed-in tariff for photovoltaics - is being reduced in many countries. When feed-in tariff is lower than the purchase tariff, the benefits of having a PV-system are shifting from selling energy to self consumption of PV energy. In tis case, however, the proper choice of PV-arrays size is not trivial and depends also on the owner self-consumption pattern. The paper investigates the sizing of PV-system for a several types of self-consumption with feed-in tariffs lower than purchase tariffs. The calculations are performed for a full year period with recorded irradiance data. The use of optional short-term energy storage has also been investigated. The calculations have been preformed for several feed-in vs purchase tariff ratios and consumption profiles.
