Solar modules have an average lifespan of around 25 years. Regular maintenance is important to keep them performing. You should regularly clean the solar panels to remove dust and dirt that could affect their efficiency. In addition, it is advisable to check and, if necessary, adjust the fixings to ensure that the modules are mounted firmly and securely. In some cases, wiring and connector checks may also be required to ensure proper operation. It is recommended to follow the manufacturer's instructions for maintenance and care in order to ensure the maximum service life and performance of your solar modules.
