Solar panels are a great renewable energy source, but they can face some common issues over time. One major problem is reduced efficiency due to dirt, dust, or bird droppings blocking sunlight. Regular cleaning helps maintain performance. Shading from trees or nearby buildings can also lower energy output. Weather-related damage, such as hail, heavy rain, or strong winds, can cause cracks or loosen connections, affecting the panel’s function. Faulty wiring or inverter issues may lead to poor power conversion, requiring professional inspection. Degradation over time is natural, as solar panels lose efficiency gradually, usually around 0.5% per year. Hot spots occur when parts of the panel overheat due to defects, leading to permanent damage. Lastly, poor installation can result in loose mounts or weak electrical connections, impacting overall performance. Regular maintenance and professional servicing can help prevent these issues and ensure long-term efficiency of your solar panels.
