From our results below, it is clear that the cost of UK solar PV electricity is quickly decreasing over time, across all PV system sizes for both approaches used. Although the cost decrease is slowing down over time, it is still very significant, even in the last several years.
The high latitude of the UK means that the solar PV electricity cost is consistently higher than in lower latitude countries such as Spain and faces greater seasonal variability of production. On the other hand, because of their large size, countries such as the US and China span multiple climate zones and solar radiation levels.
Because of its simplicity, renewable nature, and continuously decreasing costs, solar PV should be at the forefront of the government's plans to greatly expand renewable electricity generation and reduce the carbon footprint of the UK.
