As environmental concerns are constantly increasing, which generates a demand for sustainable energy solutions, Solar Panels have emerged as the hope to tackle such a situation. Harnessing the power of the sun to create clean and renewable energy, solar panels are a pretty popular choice around the UK.
Whilst solar panels are known to be energy- and environment-efficient, one question that often strikes through everyone’s minds: ' Do Solar Panels Have a Long Lifespan?’ To answer this question, you need to read through this blog.
The Average Lifespan Of Solar Panels
Solar panels are an excellent way to light up your home and save some bucks from your pocket.
On average, the lifespan of solar panels ranges from 25 to 30 years. However, many solar panels might last even longer if maintained properly. Surprisingly, some solar panels have operated for over 40 years and still produce electricity.
Solar panels degrade over time, producing less energy as they age. The degradation rate is typically around 0.5% per year, so after 25 years, a solar panel will still have about 90% of its original output.
Solar panel's lifespan also depends on the manufacturers. Some offer 40 to 50 years of warranties, while others stay to the standard of 25-30 years. In other words, solar panels are a good investment in the long run.
Factors That Affect Solar Panel Lifespan
Various factors influence solar panel’s durability or longevity, such as:
Quality of Materials: The quality of materials used in manufacturing solar panels plays a significant role in their lifespan. High-quality materials are more resistant to wear and tear caused by environmental factors and temperature fluctuations.
Investing in the best quality solar panels or tiles is best advised so that they continue to operate for years to come. Marley Solar Tiles, renowned for its quality and design, has become people’s favourite.
Climate and Weather Conditions: The climate in which solar panels are installed can significantly influence their lifespan. Panels exposed to extreme temperatures, heavy rainfall, snow, hail, and harsh winds may experience more wear and tear over time. Solar tiles and panels best work in the areas of sunshine.
Ultraviolet (UV) Radiation: Solar panels are constantly exposed to sunlight, including UV radiation. Over time, prolonged exposure to UV rays can cause degradation of materials and reduce efficiency. Solar tiles with protective UV coatings can help mitigate this effect.
Humidity and Moisture: During rainy and summer periods, moisture penetrates the panel's components, leading to corrosion and reducing overall performance. Places with high-humidity environments or solar panels with poor sealing are more prone to this issue.
Dust and Dirt: Accumulation of dirt, dust, bird droppings, and other debris on the surface of solar panels can block sunlight and reduce energy production. Therefore, you must ensure that solar tiles are regularly cleaned and debris-free.
Installation Quality: The proper steps should be taken to install solar panels for their longevity. Poorly installed panels must be securely fixed or positioned optimally, making them more vulnerable to environmental stressors.
Physical Damage: Accidents such as fallen branches or hailstorms can cause physical damage to the solar tiles, reducing their efficiency and lifespan. You must make sure that your roof is free of these possible dangers.
Corrosive Substances: If solar panels are installed near industrial sites or areas with high levels of air pollution, exposure to corrosive substances in the air can accelerate panel degradation.
Inverter Lifespan: Solar panels are often connected to inverters, which convert the DC electricity generated by the panels into AC electricity for use in homes or businesses. Inverter lifespan also impacts the overall system's longevity.
Technological Advances: As solar technology evolves, newer panels might be more durable and efficient than older models. Upgrading to more contemporary solar panels could extend the lifespan of your entire solar roofing system.
These are a few factors which determine the lifespan of solar panels. The longevity of the solar tiles and panels depends on how you maintain them.
How To Make Solar Panels Last Longer On A Roof?
To make solar panels last longer, you can adopt many ways.
Firstly, the most critical aspect is that regular cleaning is crucial to prevent dirt, debris, and bird droppings from obstructing sunlight and reducing efficiency. Use water and a soft brush to avoid abrasive materials that could scratch the panels.
Trimming nearby trees that come over your roof can minimise shading and prevent falling branches from damaging the panels.
Regular checks for loose wiring, cracks, or corrosion can help catch problems early and prevent further damage.
Invest in quality installation, including proper flashing and mounting to withstand weather conditions. Additionally, you may use tilt or elevation mechanisms that allow panels to shed snow or debris more efficiently, reducing stress on the system.
Lastly, consult with roofing professionals and adhere to manufacturer guidelines for maintenance and warranties to ensure that your solar panels remain efficient and durable over the long term, maximising their overall lifespan and benefits.
Do Solar Panels Lose Efficiency With Age?
Yes, solar panels lose efficiency with age. The amount of electricity that they can generate declines gradually over time. The degradation rate is typically around 0.5% per year, but it can vary depending on the quality of the panels.
Solar panel degradation is primarily due to the gradual wear and tear as they are exposed to sunlight, temperature fluctuations, and weather conditions over time. The most common type of degradation is caused by the breakdown of the materials within the solar cells, which can decrease the panel's ability to convert sunlight into electricity.
Upgrading And Replacing Ageing Solar Panels
If you want to upgrade or replace solar panels, follow the step-by-step guide to help you with the process:
Assessment and Evaluation: Start by evaluating the performance of your existing solar panels. Consider an upgrade if you notice a significant drop in efficiency. Also, check if the manufacturer's warranty for solar panels has expired.
Research and Planning: Research the latest solar panel technologies and brands available. Look for panels with higher efficiency, lower degradation rates, and improved durability. Consider costs, energy output, and compatibility with your existing system.
Professional Consultation: Consult with solar energy professionals or installers. They can provide valuable insights into the feasibility of upgrading or replacing your panels. They'll assess your current system, energy needs, roof space, and other relevant factors to recommend the best solution.
Compatibility Check: If upgrading only a portion of your panels, ensure the new solar panels are compatible with your existing inverter and system. If not, you should upgrade the inverter as well.
Permitting and Documentation: Check if any permits, such as building regulations, are required for the upgrade or replacement. Ensure you have all the documentation for warranties, rebates, and incentives.
Monitoring and Maintenance: After installing new solar panels, monitor the performance regularly. Many solar panels come with monitoring systems that allow you to track energy production. Perform routine maintenance to keep your solar panels or tiles clean and in optimal condition.
Recycling And Disposal Of Old Solar Panels
Yes, solar panels can be recycled. The recycling process for solar panels is still evolving, but it is becoming more efficient and widespread. The recycling process for solar panels typically involves the following steps:
-
Collection and transportation to a recycling facility.
-
Panels are disassembled
-
The materials are then recycled into new products.
The recycling process for solar panels is less efficient than other materials, such as plastic and metal. However, it is improving all the time. As the demand for solar panels increases, the recycling industry must also increase its capacity to recycle solar panels.
