Frequently Asked Questions

What is the lifespan of solar panels in the UK?

Solar panels typically have a lifespan of 25 to 30 years, with many manufacturers offering warranties that guarantee performance for at least 25 years. Over time, panels may experience a gradual decrease in efficiency, usually around 0.5% to 1% per year. Regular maintenance and cleaning can help maximise their lifespan and efficiency, ensuring that homeowners continue to benefit from renewable energy for decades. It’s essential to choose high-quality panels from reputable manufacturers to ensure longevity and reliability.

How do weather conditions affect solar panel performance?

While solar panels are most efficient in direct sunlight, they can still generate electricity on cloudy or rainy days. In the UK, modern solar panels can produce energy even in overcast conditions, averaging around 850 kWh per kWp annually. However, extreme weather events, such as heavy snow or hail, can temporarily reduce output. It’s crucial to ensure that panels are installed at an optimal angle to maximise sunlight exposure and to consider local weather patterns when planning installation.

Can solar panels increase my home insurance premiums?

Installing solar panels may lead to an increase in home insurance premiums, as they add value to your property and may require additional coverage. However, many insurers offer discounts for homes with renewable energy systems due to their lower risk profile. It’s advisable to inform your insurance provider about the installation and discuss any potential changes to your policy. Comparing quotes from different insurers can help you find the best coverage options for your solar-equipped home.

What happens if my solar panels produce more energy than I use?

If your solar panels generate more electricity than your household consumes, the excess energy can be exported back to the grid. Under the Smart Export Guarantee (SEG), you can receive payments for this surplus energy. The tariff rates vary by energy supplier, so it’s beneficial to shop around for the best deal. Additionally, investing in battery storage can allow you to store excess energy for later use, further enhancing your energy independence and savings.

Are there any environmental impacts associated with solar panel production?

While solar panels provide significant environmental benefits during their operational life, their production does involve some environmental impacts, including energy consumption and resource extraction. However, the overall lifecycle emissions of solar panels are much lower than fossil fuels. Many manufacturers are working to improve sustainability by using recycled materials and reducing waste. It’s essential to choose panels from companies committed to environmentally friendly practices to minimise the ecological footprint of your solar energy system.

How can I monitor the performance of my solar panel system?

Most modern solar panel systems come with monitoring solutions that allow homeowners to track energy production and consumption in real-time. These systems often include mobile apps or online portals that provide insights into performance metrics, such as daily energy generation and savings. Regular monitoring helps identify any issues early, ensuring optimal performance. Some installers also offer ongoing performance monitoring services, providing peace of mind and support for system maintenance.

What should I do if my solar panels are damaged?

If your solar panels are damaged, it’s crucial to contact your installer or a qualified technician immediately. They can assess the extent of the damage and recommend appropriate repairs or replacements. Most reputable installers provide warranties that cover defects and performance issues, so check your warranty terms. Additionally, regular maintenance can help prevent damage from environmental factors, ensuring your system remains in good working order and continues to generate energy efficiently.
