Several factors influence the overall cost of installing solar panels. Firstly, the type and quality of solar panels play a significant role. High-efficiency panels, such as those using monocrystalline silicon, are more expensive but offer better performance (Renewable Energy Hub, 2023). Secondly, installation costs vary depending on the complexity of the installation and the installer’s rates. Roof orientation, angle, and accessibility can affect labour costs.


Geographical location also impacts costs. While the price of solar panels themselves is relatively consistent across the UK, regional differences in labour costs can lead to price variations (Solar Guide, 2023). Additionally, the inclusion of battery storage systems adds to the initial investment but allows homeowners to store excess energy, increasing self-consumption rates.


Finally, market dynamics such as supply chain fluctuations, global demand for photovoltaic materials, and government policies can influence prices. For instance, any changes in tariffs on imported solar equipment post-2023 could affect 2024 prices (Department for Business, Energy & Industrial Strategy, 2023). Understanding these factors can help consumers make cost-effective choices when planning their solar installations.
