This is because the empirical data necessary to calculate solar self-consumption is not widely available; an issue common to many countries. Without electricity metering that records solar PV generation, imports and exports, it is impossible to know exactly how much solar power is being used directly in the household, and as a result,
Photovoltaic Self-consumption: The Energy of the Future at Home
Photovoltaic self-consumption refers to the use of solar panels to generate electricity that is consumed in the same place where it is produced, usually in homes or businesses. This means you can produce your own energy, reducing your dependence on the grid and optimising your costs.

6 FAQs about [Solar photovoltaic self-generation]
What is the percentage self-consumption of solar PV?
The percentage self-consumption of solar PV is an indication of how much of the electricity produced by a domestic solar PV array that has been consumed by the household. If half of the electricity produced by the PV is consumed by the household, the percentage self-consumption is 50%.
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.
How can a solar PV system increase self-consumption?
An increase in self-consumption of the solar PV can be achieved using the following methods: Install domestic battery storage to store excess electricity generation for consumption later in the day. Install a solar immersion controller. This can use excess solar generation to power the immersion heater for a hot water cylinder.
What does solar self-consumption mean?
Self-consumption of photovoltaic (PV) renewable energy is the economic model in which the building uses PV electricity for its own electrical needs, thus acting as both producer and consumer, or prosumer. In this model, the PV-generated energy is consumed instantaneously as it is being produced.
Are solar panels causing a rise in photovoltaic self-consumption?
The increase in the use of solar panels in recent years is linked to an increase in photovoltaic self-consumption.
How does solar PV affect electricity consumption?
The percentage self-consumption decreases with increased solar PV generation and when the household spends less time at home during the day. This means a higher proportion of the electricity is being exported to the grid and the household would benefit by shifting electricity consumption to times when there is greater generation from solar PV.
