Professional Solar Cleaning in Tullamarine

While there isn't a single rule, your location in VIC dictates the frequency:

• Melbourne Metro: Usually once a year is enough to clear urban dust and pollution.
• Leafy Suburbs (e.g., eastern suburbs): Every 6 months due to heavy tree sap and debris.
• Rural/Regional VIC: Every 3–6 months, especially during the dry summer months when dust from paddocks or harvest activity is high.
• Coastal Areas (e.g., Mornington Peninsula): Every 6 months to prevent salt-crust buildup which can corrode components.

Not entirely. While a heavy Victorian downpour can rinse off loose dust, it often creates a "muddy" film if the rain is light. Rain also cannot remove:

• Sticky Pollen: Common in spring across the state.
• Bird/Bat Droppings: These are acidic and can "etch" the glass if left to bake in the summer sun.
• Lichen: This moss-like growth thrives in damp, shaded Victorian roofs and requires manual scrubbing to remove.

Yes, but with big caveats from Energy Safe Victoria (ESV).

• Safety: ESV and Solar Victoria strongly recommend staying off the roof. If you do it yourself, use a telescopic pole with a soft brush from the ground or a ladder.
• The "Electrical" Factor: Cleaning only deals with the glass. Victoria’s safety guidelines state that a full electrical service—which checks for fire risks like faulty DC isolators—must be done by a licensed A-Grade electrician every 2 years.

In Victoria's variable climate, timing is about protecting the glass from "thermal shock":

• Early Morning or Late Evening: Never clean panels in the middle of a hot 30°C+ day. If you spray cold water onto glass that has been baking in the sun, the panels can crack.
• The "Water Only" Rule: Avoid Melbourne tap water if possible, as it can be "hard" and leave mineral streaks. Use a soft brush and plain water; never use a high-pressure washer (like a Karcher), as it can destroy the seals and force water into the electrics.
