A LUMINOUS system typically requires very little maintenance and are incredibly durable. If possible, we do recommend getting your panels cleaned once or twice a year. Using your garden hose should be enough to rinse your panels. If you’d like to do a deeper clean, we recommend using a 1-part vinegar, 2-parts water solution every six months to reduce mineral deposits and keep your panels operating at maximum efficiency.
We recommend that any rinsing be done in the early morning while the panels are still cool.
