The main principle of PV power generation is the photoelectric effect of semiconductors. The PV panel uses the received solar radiation to generate electricity, and the generated electricity is processed by the controller and inverter and then stored in the electricity storage device via the filtering circuit to supply power to applications.
PV power generation includes PV power generation and grid-connected PV power generation, and the scope of this paper focuses on solar energy harvesting technologies for PV self-powered applications, which belongs to the former scope. There are many studies on PV self-powered technologies, but there has been no review of this field.
To further advance the research about self-consumption of PV electricity, the following aspects need to be further investigated: Forecasts of solar irradiation to optimize the self-consumption with PV-storage and DSM systems and how to integrate them into energy management systems for buildings, such as examined in .
Conclusions This review paper has summarized previous research in the field of self-consumption of electricity from residential PV systems. Self-consumption is in this review defined as the share of the PV production that is consumed in the household.
For Europe the challenge is even bigger as electricity emissions in Europe should decrease to 45g CO 2 /kWh by 2050. Recent 100% renewable electricity scenarios have highlighted the importance of solar photovoltaics to achieve this goal and decarbonise the power sector in a cost effective manner.
An Italian residential case study is used as example. In this case, results show that the cost-effectiveness of photovoltaic generators is so high that it permits also the installation of expensive batteries and reaches a level of self-sufficiency of around 64%, keeping the internal rate of return higher than a threshold of 6%.
