Solar panels have a long lifespan, but after around 15 years, defects may start to occur that reduce the efficiency of your installation. Especially if your solar panels are receiving green certificates, it is essential to monitor the output and detect defects in a timely manner. This is particularly important for systems that will still be eligible for certificates in the next five years, as the output of defective panels affects the number of certificates you can claim.
The Impact of Defects on Output
Solar panels that are 15 years old often show defects such as damaged cells or faulty diodes. These defects can cause one or more panels to no longer function optimally, which lowers the output of the entire string. This loss can be significant, especially in older installations, which means that fewer green certificates will be received, resulting in lower income from these certificates.
Why an Inspection is Essential
A regular inspection can detect these defects and help maximize the output of the installation. By identifying the losses, necessary repairs or replacements can be made. This prevents further reduction in output and ensures that you can still benefit from the full value of your green certificates.
