Autumn in Coffs Harbour brings cooler weather and shorter days, which can affect your solar system’s output. However, despite popular belief, this doesn’t always mean a significant reduction in power generation. So, here’s how to prepare your solar system for autumn’s challenges.
Clean Your Solar Panels
This is perhaps the most important maintenance task to maximise your panel’s efficiency. Leaves, dust, and coastal salt can build up on solar panels, blocking sunlight. Clean them before autumn sets in to capture every ray. Use a soft cloth and soapy water, or a hose for hard-to-reach spots but avoid harsh or corrosive chemicals. Most systems need cleaning twice a year, and Coffs’ salty air makes this step vital.
Check for Solar System Shade
As the sun sits lower in autumn, nearby trees or new structures might cast shadows on your panels. Moreover, even partial shade cuts power; studies show a 10% shaded panel can lose 50% of output. So, walk your property at midday to spot issues. Trim branches if needed or consult a technician to tweak panel angles.
Inspect Your Solar System
Loose connections or worn parts can sap efficiency. Look over your panels, wiring, and inverter for cracks or corrosion. An inverter showing error codes or odd noises needs attention. It’s a good idea to book a professional check every two years and autumn’s a good time to catch problems before winter.
Monitor Solar System Performance
Track your system’s production with its app or meter. A sudden dip could signal dirt or faults, not just the season. It’s best to compare to past autumns to spot trends and call a technician if the numbers don’t add up.
Clear Gutters and Drains
Falling leaves clog gutters, which can pool water near your system’s mounts. Consequently, this dampness risks rust or electrical issues. So, clear debris around panels and check roof drainage. It’s a quick job that protects your investment through wetter months.
Plan for Battery Storage
If you have a battery, autumn’s a great chance to optimise it. Shorter days mean you’ll pull more from storage at night. So, ensure your battery’s charged to capacity; most hold 10-13 kWh for home use. A technician can adjust settings to prioritise evening needs, especially with Coffs’ early sunsets.
