Fact Check: "The small-scale PV cost data from the Department of Energy Security and Net Zero (DESNZ) record a median cost of GBP 1,876 ($2,550) per kW for installations up to 4 kW and GBP 1,780 for 4 kW to 10 kW arrays, down 19% and 21% respectively against 2023 prices."
What We Know
The claim regarding the costs of small-scale photovoltaic (PV) installations is based on data from the Department for Energy Security and Net Zero (DESNZ). According to the official source, the median cost for installations up to 4 kW is indeed reported as GBP 1,876 ($2,550), while installations between 4 kW and 10 kW have a median cost of GBP 1,780. Furthermore, the data indicates that these costs represent a decrease of 19% and 21%, respectively, compared to the previous year's prices, as noted in a recent article from PV Magazine.
Analysis
The data presented in the claim aligns with the official statistics provided by the DESNZ. The figures of GBP 1,876 and GBP 1,780 for the respective installation sizes are corroborated by the small-scale solar PV cost data published by the UK government. The reported percentage decreases of 19% and 21% are also consistent with the trends observed in the data.
However, while the primary source of the claim is credible, it is essential to consider the context of the data. The costs are median figures, which can be influenced by various factors such as regional differences, the specific technology used, and market conditions. The source of the data, the Microgeneration Certification Scheme (MCS) Installation Database, is reputable, but it is crucial to recognize that median costs may not reflect the full range of installation prices across the market.
Moreover, the article from PV Magazine, while informative, is a secondary source that interprets the data rather than presenting it directly. This introduces a layer of potential bias, as the publication may emphasize certain aspects of the data to align with its narrative on market trends.
Conclusion
The claim is Partially True. The reported median costs and percentage decreases are accurate according to the official data from the DESNZ. However, the interpretation of these figures as representative of the entire market may overlook variations in installation costs due to regional and technological differences. Therefore, while the specific numbers are correct, the broader implications of these costs should be approached with caution.
