For nearly twenty years, Solar Water Wind has been at the forefront of New South Wales’ solar industry, combining compliance, innovation, and hands-on expertise to deliver dependable results. What began as a local installation business has evolved into a comprehensive renewable energy service offering inverter and solar panel repairs, system upgrades, solar air conditioners, and solar hot water solutions.
Our success comes from keeping every part of the process transparent and professional. We provide clear, itemised quotes before any work begins, and our Solar Accreditation Australia–accredited electricians follow a proven diagnostic procedure using electroluminescence (EL) imaging and drone-based inspections to locate issues with precision. This evidence-driven approach eliminates guesswork and ensures compliance with Australian Standards, giving customers full confidence in both safety and performance.
With teams based across Greater Sydney, the Central Coast, Newcastle, and Taree, we combine local expertise with fast, dependable turnaround times for residential and commercial systems. Every job is completed in-house, maintaining consistent quality control from inspection through to post-repair verification.
Recognition through Local Business Award wins and as a finalist in the Australian Small Business Champion Awards 2024 reflects that consistency. After two decades of growth, Solar Water Wind continues to raise the benchmark for transparent service, technical precision, and customer trust in NSW’s solar repair industry.
Advanced Testing and Diagnostic Equipment
At Solar Water Wind, our use of advanced testing equipment defines the accuracy of our repair process. We rely on electroluminescence (EL) testing to see what standard visual inspections and multi-meter checks can’t. When voltage is applied to a solar panel under controlled conditions, it emits a faint light pattern that reveals the condition of each cell and internal connection. Cracked cells, broken interconnect ribbons, and micro-fractures appear as dark lines or irregularities in the image, allowing our technicians to locate faults invisible to the naked eye. By identifying these weaknesses early, we prevent long-term generation losses and extend the life of the solar system as a whole.
Alongside EL testing, we use thermal imaging and IV curve tracing to assess real-time performance. Thermal cameras detect abnormal heat signatures that indicate hotspots, bypass diode failures, or wiring resistance, helping us pinpoint where power consumption is being lost. IV curve tracing, meanwhile, measures the electrical behaviour of a string or module by plotting current against voltage under load. This data shows us whether panels are degrading evenly, whether an inverter is operating within its expected efficiency range, and whether a battery discharge issue is linked to a hardware fault or a communication error.
These diagnostic tools work together to remove guesswork entirely. They allow us to verify performance before and after a repair, providing customers with measurable proof of improvement rather than assumptions. Few companies in NSW integrate this level of testing into everyday service, and it’s one of the main reasons Solar Water Wind continues to lead the way in precise, evidence-based solar repair and system maintenance.
Common issues we repair
- Storm and water damage: cracked or shattered solar panels, lifted rails, broken tiles, flooded rooftop isolators, MC4 connector failure, water ingress into junction boxes, surge damage to inverters and batteries, corrosion after heavy rain or hail.
- Inverter faults: relay or isolation faults, DC bus or IGBT failures, fan failure, overheating and thermal derating, persistent error codes, repeated rebooting, incorrect grid profile, overvoltage or undervoltage, frequency out of range.
- Battery issues: battery not charging or not discharging, BMS errors, state of charge stuck or inaccurate, cell imbalance, high or low temperature lockout, contactor faults, firmware mismatch between inverter and battery.
- Communication failures: Wi-Fi dropouts, Ethernet link loss, 4G modem faults, RS485 or CAN wiring issues, PLC noise on power lines, portal not updating, time and date drift causing monitoring gaps.
- Grid and metering problems: CT clamp reversed, CT not on correct phase, export limit misconfigured, zero-export rules not applied correctly, DNSP overvoltage at the street causing repeated inverter disconnects, phase imbalance on three-phase sites.
- Solar panel underperformance: shading, soiling, hot spots, delamination, snail trails, potential induced degradation (PID), failed bypass diodes, micro-cracks confirmed with electroluminescence, mismatch between strings and MPPT inputs.
- DC side safety faults: earth faults, insulation resistance failures, damaged DC cabling, melted MC4s, water logged rooftop isolators, arcing and RCD trips.
- Configuration and commissioning errors: wrong country code or grid standard, incorrect battery settings for charge and discharge limits, off-grid or backup mode set unintentionally, time-of-use settings not aligned with tariff, reactive power or power factor set incorrectly.
- Monitoring and controls: third-party smart meters not paired, inverter app firmware out of date, API tokens expired, home energy management automations throttling output and confusing power consumption readings.
