Price from solar panel foundation to weak electricity

Is the cost of UK solar PV electricity decreasing over time?

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.

Are solar PV projects reducing the cost of electricity in 2022?

Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.

Can rooftop solar save you money?

In many markets, households can still generate savings by installing rooftop solar. Including all costs of installing a solar rooftop, the electricity generated over its lifetime—the unsubsidized levelized cost of energy (LCOE) 1 —is still cheaper than comparable grid electricity in many markets.

Why is solar energy so expensive in the UK?

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.
