Overview
REC Solar Panel Repairs & Servicing Perth
REC has been a prominent name in the solar industry since its establishment in Norway in 1996. While these panels are known for their durability, decades of exposure to harsh environmental conditions will eventually take a toll on any system. If your REC solar array is underperforming or your associated battery storage has developed a fault, our Perth team can identify the issue and carry out the necessary repairs.
Servicing REC Solar Panel Technologies
Over the years, REC has released several panel types across residential and commercial sites in Perth. We commonly inspect and service the TWINPEAK series, which uses a half-cut cell design, as well as the ALPHA series known for its heterojunction technology. We also handle newer installations featuring models like the REC Alpha Pure-RX 470W All Black. While the panels themselves are built to withstand tough conditions, the surrounding infrastructure such as rooftop isolators, cabling and connectors often require maintenance. We trace faults through the entire DC array to determine if a drop in output is due to panel degradation, a blown isolator or a problem elsewhere in the circuit.
How Perth Conditions Affect Your Solar Array
Western Australia presents a challenging environment for rooftop electronics. High summer temperatures, intense UV radiation, coastal salt spray and seasonal dust all accelerate wear on solar installations. Prolonged heat can degrade the seals around solar panels, potentially allowing moisture ingress that leads to earth faults. Dust build-up along the lower edge of panels can cause hot spots, which permanently damage the solar cells over time. Coastal suburbs also see accelerated corrosion on mounting frames and electrical enclosures. Routine cleaning and visual inspections are the most effective ways to catch these environmental wear factors before they cause a complete system shutdown.
- Moisture ingress from degraded seals
- Hot spots caused by heavy dust accumulation
- UV damage to exposed cabling and conduits
- Corrosion on mounting hardware near the coast
Diagnosing Battery Storage Faults
Many Perth homes with REC solar panels also utilise battery storage to capture excess energy rather than sending it back to the grid. We service associated storage systems, including the LG Chem RESU 6.5LV 48V lithium-ion battery, as well as the RESU10H-Type C, RESU10H-Type R, and RESU LV 3.3-9.8 units. Battery management systems can experience software glitches or hardware failures that prevent the unit from charging or discharging correctly. Heat is a major factor in battery degradation, often reducing the capacity or lifespan of the internal cells. We test communication cables, check error logs and verify voltage levels to determine if the battery needs a repair or replacement.
Warning Signs and Repair Economics
The most obvious sign of a solar fault is a sudden spike in your household electricity bill or a red fault light on your inverter. You might also notice irregular power output during peak sunlight hours. When evaluating a faulty system, we look at the repair versus replacement economics. Replacing a single damaged REC Alpha Pure-RX 470W All Black panel might be cost-effective, but if an older array has widespread moisture damage or extensive micro-cracking, upgrading the entire string is often the smarter financial decision. We provide an honest assessment of your equipment so you can decide whether a repair will yield enough functional lifespan to justify the cost.
FAQs
Common questions
Why is my REC solar array producing less power than it used to?
A gradual drop in output is normal as panels age, but a sudden decrease usually indicates a fault. This could be due to heavy dust accumulation, a failed bypass diode, a damaged rooftop isolator, or a problem with the inverter. We can test the DC voltage of your strings to pinpoint the exact location of the power loss.
Can a single damaged REC panel be replaced?
Yes, if a single panel is shattered by impact or fails electrically, it can be replaced. However, the replacement panel must match the electrical characteristics of the existing string. If the exact model, such as an older TWINPEAK series, is no longer available, we will source a compatible alternative that works safely with your inverter.
How do I know if my LG Chem RESU battery has failed?
You will typically see a fault light on the battery unit or the connected hybrid inverter. You may also notice that your home begins drawing power from the grid as soon as the sun goes down, indicating the battery is not storing or discharging energy. Heat stress or degraded internal cells are common culprits.
Do REC panels require regular servicing?
While solar panels do not have moving parts, the electrical connections, rooftop isolators and mounting hardware require routine checks. Annual or biennial inspections help identify UV damaged cables, loose connections or early signs of water ingress before they escalate into dangerous electrical faults or system failures.
