Solar panels are becoming an increasingly popular option for homeowners in the UK looking to reduce their energy bills and carbon footprint. However, one of the concerns that people may have when considering installing solar panels is how much they weigh. In this article, we will explore the weight of solar panels and what factors can affect their weight.
How much does a solar panel weigh?
The weight of a solar panel can vary depending on a number of factors, including its size, type, and manufacturer. On average, a standard 60-cell solar panel weighs around 18kg, while a 72-cell panel can weigh up to 22kg. However, some premium solar panels can weigh as much as 30kg or more.
It is important to note that the weight of a solar panel is not the only factor to consider when installing solar panels. The weight of the mounting system, which is used to secure the solar panels to the roof, must also be taken into account. Additionally, the weight of the solar panels can add extra load to the roof structure, which may be a concern for older or weaker roofs.
Factors affecting the weight of solar panels
1. Size
The size of a solar panel can have a significant impact on its weight. Larger panels generally weigh more than smaller ones, as they require more materials to manufacture. For example, a typical 60-cell panel measures around 1m x 1.65m, while a 72-cell panel measures around 1m x 2m. The extra size and weight of the 72-cell panel mean that it can generate more power but may be more challenging to install.
2. Type
There are two main types of solar panels: monocrystalline and polycrystalline. Monocrystalline panels are made from a single crystal of silicon, while polycrystalline panels are made from multiple crystals. Monocrystalline panels are generally more efficient and therefore can generate more power, but they are also heavier than polycrystalline panels.
3. Manufacturer
Different manufacturers use different materials and manufacturing processes, which can affect the weight of solar panels. Premium solar panels often use higher quality materials and may weigh more than standard panels.
4. Mounting system
The mounting system is used to secure the solar panels to the roof. The weight of the mounting system can vary depending on the type of roof and the size and weight of the solar panels. It is essential to ensure that the mounting system is strong enough to support the weight of the solar panels and any additional load that they may add to the roof.
Why is the weight of solar panels important?
The weight of solar panels is an important consideration for several reasons. Firstly, the weight of the panels can affect the cost of installation. The heavier the panels, the more expensive the mounting system may be, as it will need to be stronger and more robust.
Secondly, the weight of the solar panels can impact the safety of the installation. If the panels are not installed correctly, they can pose a risk to the safety of the homeowners and anyone else who may come into contact with them. It is essential to ensure that the panels are installed by a qualified and experienced installer to ensure that they are safe and secure.
Finally, the weight of the solar panels can affect the performance of the system. If the panels are too heavy for the roof to support, they may not be able to generate as much power as they would if they were installed correctly. This could result in lower energy savings and a less efficient system overall.
Conclusion
The weight of solar panels is an important consideration when deciding whether to install them on your property. While the weight of a standard solar panel is around 18kg, other factors such as size, type, and manufacturer can affect their weight. It is essential to ensure that the mounting system is strong enough to support the weight of the panels and that they are installed correctly to ensure their safety and efficiency. By choosing a reputable installer and following the manufacturer’s guidelines, you can enjoy the benefits of solar panels without worrying about their weight.
