What are the benefits of regular solar panel maintenance?

Regular solar panel maintenance offers several advantages:
  • Increased Energy Efficiency: Clean and well-maintained panels produce more energy, maximizing your solar savings.
  • Extended System Lifespan: Regular inspections and timely repairs can prevent minor problems from escalating into major issues, prolonging the lifespan of your solar system.
  • Reduced Repair Costs: Catching problems early can prevent more extensive and costly repairs down the line.
  • Improved Safety: Maintenance checks can identify potential electrical or fire hazards, keeping your system safe.
  • Warranty Compliance: Some solar panel warranties require regular maintenance to remain valid.

What are the most common solar panel problems?

Some of the most common solar panel problems include:
  • Panel Degradation: Over time, solar panels naturally lose some efficiency, typically less than 1% per year.
  • Shading: Objects, like trees, buildings, or even bird droppings, can block sunlight from reaching the panels, reducing their output.
  • Microcracks: Tiny cracks in the solar cells can affect performance. These cracks may not be visible to the naked eye.
  • Inverter Issues: Inverters can malfunction due to various reasons, including overheating, electrical surges, or component failure.
  • Wiring Problems: Loose, corroded, or damaged wiring can disrupt the flow of electricity from the panels to the inverter.
  • Roof Leaks: Water damage from roof leaks can affect the panels and wiring.
  • Pest Infestation: Rodents or birds can sometimes damage wiring or nesting under panels.
Regular inspections and maintenance can help prevent or detect many of these problems early on.

How does shading affect solar panel efficiency?

Shading can significantly reduce the efficiency and energy output of solar panels. Even partial shading on a single panel in a string can impact the performance of the entire string. When a solar cell is shaded, it acts as a resistor, reducing the current flow in the entire circuit. This is why it's crucial to choose a solar panel system that incorporates:
  • Microinverters or Power Optimizers: These devices can mitigate the effects of shading by optimizing the output of each individual panel.
  • Strategic Panel Placement: A qualified installer will assess your roof and design a system layout that minimizes potential shading from trees, buildings, or other obstructions.

What are solar panel arc faults, and how are they prevented?

An arc fault in a solar panel system is a dangerous electrical hazard that occurs when electricity jumps or arcs between conductors. This can happen due to damaged or loose wiring, faulty connections, or other electrical issues. Arc faults generate intense heat and can ignite flammable materials, posing a significant fire risk. To prevent arc faults:
  • Use high-quality wiring and components.
  • Ensure proper installation by a qualified electrician.
  • Install arc-fault circuit interrupters (AFCIs) in your solar panel system. AFCIs are safety devices designed to detect and interrupt arc faults, protecting your system and property from fire hazards.
  • Regularly inspect wiring and connections for any signs of damage or looseness.
