Solar panel prices have fallen by approximately 20% every time global capacity has doubled, following a trend known as Wright's Law. Solar panels can convert 22% of sunlight into electricity, whereas the first solar panels could only convert 1-2% into electricity. This has helped drive down costs as the panels are more efficient.
Data collected by GOV.UK shows that the cost of solar panels in March 2024 either decreased, increased or remained stable depending on the wattage from the previous year. 4-10kW solar panel cost remained stable. 10-50kW solar panel cost increased by 5.8%. The above shows that within a single year, supply and demand influence solar panel prices.
Research from Our World in Data claims solar panel costs have dropped by 90% in the last decade, whilst onshore wind has also fallen by 70% and solar batteries by more than 90%. These technologies have followed a pattern called Wright's Law, according to World in Data, which states that technology costs consistently drop as production increases.
This significant price drop means homeowners can manage their energy expenses more effectively while reducing their environmental impact. This year marks a pivotal moment in the solar revolution, with projections indicating that the cost of solar modules will reach an unprecedented low of just £0.10 per watt by the end of 2024.
