A Guide To Solving Solar Panel Problems

With Sydney’s abundant sunshine, solar energy is an absolute winner. But even the best solar panels can experience hiccups now and then. Fear not! This comprehensive guide will walk you through solar panel troubleshooting like a seasoned pro.

Recognising common solar panel issues

Solar panels are generally low-maintenance, but sometimes they need a bit of TLC. Here are some prevalent problems to watch out for:

  • Diminished efficiency: Grime, dust and bird droppings can accumulate on your panels, impeding their performance.
  • Micro-fractures: Drastic temperature fluctuations, hail, or other environmental factors may cause minuscule cracks in the solar cells, affecting efficiency.
  • Dislodged connections: Inclement weather, wear and tear, or critters can cause connectors to become loose, resulting in reduced energy output.
  • Inverter malfunctions: The inverter is the linchpin of your solar system. If it falters, your solar panels won’t generate usable electricity.
  • Shading concerns: Neighbouring trees, structures, or obstructions can cast shade on your panels, significantly decreasing their output.

A step-by-step guide to inspecting your solar panels

A visual inspection is your first port of call when troubleshooting solar panels. Here’s how to conduct one:

  • Power down the system: Safety first, mate! Deactivate your solar system at the inverter and the main switchboard.
  • Assess visible damage: Inspect your solar panels for cracks, discolouration or other indicators of physical harm.
  • Verify connections: Make sure all wires and connections are secure and intact.
  • Identify shading: Evaluate whether nearby objects are casting shadows on your panels, particularly during peak sunlight hours.
  • Spruce up your panels: Gently clean your solar panels with a soft brush and water, removing any dirt or debris.

Diving deeper: Advanced solar panel testing techniques

If the visual inspection doesn’t yield results, you may need to dig a bit deeper:

  • Investigate the inverter: Examine the inverter display for error messages or abnormal readings, and consult your manual for troubleshooting advice.
  • Assess the panels: Utilise a multimeter to measure the voltage and current output of each panel, comparing them to the manufacturer’s specifications.
  • Examine connections: Inspect and test all connectors, junction boxes, and cables for signs of wear, damage, or corrosion.
  • Call in the cavalry: If you’re still stumped, it’s time to enlist the help of experts in solar panel repairs and servicing.

Maintaining your solar system for optimal performance

An ounce of prevention is worth a pound of cure! Keep your solar system in shipshape with these tips:

  • Consistent cleaning: Keep your panels sparkling by removing dirt and debris every few months.
  • Annual check-ups: Organise a professional inspection at least once a year to ensure your system is operating at peak performance.
  • Keep an eye on performance: Frequently check your inverter display or solar monitoring app to track your system’s performance and detect potential issues early.
  • Prune foliage: Trim trees and shrubs to prevent shading and reduce the risk of damage from falling limbs.
