A yearly visual inspection of thesolar engine is typically sufficient. The system is designed to be maintenance free, but maximum systemperformance is achieved when the LED lenses and solar panels are clean. When inspecting the interior, ensurethat the vent screens are undamaged and that the vents are clear and allow airflow.8.1 Fuse ReplacementTo replace the fuses:1.
