Solar panels are an increasingly popular form of renewable energy in the United Kingdom, with installations increasing year-on-year. However, many people are unsure where solar panels are manufactured and how the process works. In this article, we will explore where solar panels are manufactured, including the different stages of the manufacturing process.
The majority of solar panels installed in the UK are manufactured abroad, with the main countries of origin being China, Germany, and the United States. China is the world’s largest manufacturer of solar panels, producing around 70% of the world’s supply. Many of the UK’s solar panels are imported from China due to the lower cost of production and the availability of resources.
The manufacturing process of solar panels can be split into several stages. The first stage is the production of polysilicon, which is the raw material used to make solar cells. Polysilicon is produced by heating silica in a furnace and then adding a carbon source, such as coal or natural gas. This process is energy-intensive and can take several weeks to complete.
The next stage is the production of solar cells, which are the individual components that make up a solar panel. The process involves cutting thin wafers from the polysilicon and then doping them with impurities to create a positive and negative charge. These wafers are then assembled into solar cells, which are wired together to create a solar panel.
Once the solar cells have been assembled, they are encapsulated in a protective layer of glass or plastic. This layer not only protects the solar cells from damage but also helps to improve their efficiency by reducing reflection and increasing light absorption.
Finally, the solar panels are fitted with a frame and wiring to enable them to be connected to the electrical grid. The completed panels are then tested and certified to ensure they meet the required safety and performance standards.
While solar panels are primarily manufactured abroad, there are a few UK-based companies that produce solar panels. These companies tend to focus on niche markets, such as building-integrated photovoltaics (BIPV) or off-grid systems. Some examples of UK-based solar panel manufacturers include Romag, Solarcentury, and GSP Energy.
In addition to solar panel manufacturers, there are also UK-based companies that produce the components used in solar panels. For example, PV Crystalox Solar is a UK-based company that produces polysilicon, while Morgan Advanced Materials produces the ceramic components used in solar panels.
In conclusion, while the majority of solar panels installed in the UK are manufactured abroad, there are a few UK-based companies that produce solar panels and components. The manufacturing process for solar panels involves several stages, including the production of polysilicon, the assembly of solar cells, and the encapsulation of the panels in a protective layer. Despite the reliance on imported solar panels, the UK’s solar industry is growing rapidly, with installations increasing year-on-year as the country seeks to transition to a low-carbon economy.
