How to increase self-consumption rate of photovoltaic-generated electricity?
One possible option to increase the self-consumption rate of photovoltaic-generated electricity is the use of a battery bank that stores excess solar electricity during sunshine hours which is later used in the evening (Jallouli and Krichen, 2012, Gitizadeh and Fakharzadegan, 2014, Lupangu and Bansal, 2017).
What is photovoltaic self-consumption?
Photovoltaic self-consumption occurs when individuals or companies consume the energy produced by photovoltaic generation installations located close to the place in which that energy is consumed.
Can solar energy storage systems improve self-consumption and self-sufficiency?
As energy storage systems are typically not installed with residential solar photovoltaic (PV) systems, any “excess” solar energy exceeding the house load remains unharvested or is exported to the grid. This paper introduces an approach towards a system design for improved PV self-consumption and self-sufficiency.
Can solar energy harvesting technologies be used for PV self-powered 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.
What is PV power generation?
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.
What is photovoltaic energy?
The term "photovoltaic" is made up of the words "photo", which comes from the Greek word "phos", meaning "light"; and "voltaic", which originated in the field of electricity, as a tribute to the physicist Alessandro Volta, who invented the battery. Photovoltaic energy can therefore be defined as energy produced by light.
