Solar Panel Cleaning and Service

Is Cleaning Your Solar Panels Worth it?

studies have shown that dirty solar panels can experience power losses ranging from 5% to 35% Regular maintenance and cleaning of solar panels are essential to maximize their efficiency and power output. By keeping the panels clean and free from debris, you can ensure that they operate at their optimal performance level and generate the maximum amount of electricity.

What are the Solar System Inspection Service Provided by Us?

1. Electrical Diagnostics and Repairs:

• Live Electrical Testing: Using multimeters, clamp meters, and megohmmeters to test voltage, current, and resistance on live DC circuits (which can be far more dangerous than typical home AC electricity). A mistake can lead to catastrophic arc flashes, severe burns, or electrocution.
  

• Replacing Inverter Components if required only : Inverters are complex pieces of equipment with capacitors that can hold a lethal charge even after being switched off. Their installation and replacement must be done by a professional to ensure proper commissioning, communication setup, and warranty preservation.

• Repairing or Replacing Wiring, Conduit, and Connectors (MC4): Working with the specialized, high-voltage DC wiring and connectors used in solar arrays requires specific tools and training. An improperly seated MC4 connector can lead to arcing and fire.

2. Advanced Diagnostic Testing:

• Thermal Imaging (Thermography) with a Drone or Camera: While you can rent a thermal camera, interpreting the results accurately requires expertise. A professional can distinguish between a problematic hotspot, a temporary shadow, and a reflection. They also have the training to perform this work safely on a roof.
  

3. Physical Repairs and Modifications:

• Panel Replacement if required : Removing and replacing a damaged panel involves working on the racking system, disconnecting high-voltage DC strings, handling heavy and fragile glass objects on a roof, and properly reinstalling and torqueing all electrical connections to the manufacturer’s specifications. Incorrect torque is a major cause of failures.

• Racking System Repairs or Modifications if required : Assessing the integrity of the mounting system, ensuring it is still properly sealed to prevent roof leaks, and making any repairs requires knowledge of both roofing techniques and structural engineering principles.

4. Safety and Compliance Services:

• Isolation (Insulation Resistance) Testing: This test, often required after repairs, checks for current leakage to the ground. It requires a megohmmeter and must be performed correctly to avoid damaging system components while verifying safety.

• Commissioning after Repairs: After any significant repair, a professional will ensure the system is recommissioned correctly: checking all communication links, updating firmware, verifying production metrics, and ensuring it is synchronizing properly with the grid.

• Warranty Claims and Manufacturer Liaison: we know how to properly document issues for warranty claims, work directly with panel and inverter manufacturers, and ensure any replacements are done without voiding the remaining system warranties.

Why Select a Company With 60 Years History and SLEA Registration :

• High Voltage DC Danger: A solar array’s DC electricity does not “switch off” like home AC power when you flip a breaker. As long as the sun is shining, the panels are producing lethal voltage. Professionals are trained in Safe Work Practices for dealing with this hazard.

• Fall Risk: Working on a roof is inherently dangerous. Professional installers have fall protection gear and training.

• System Complexity: Modern systems are complex with integrated communications and rapid shutdown systems. Incorrect handling can disable safety features or cause widespread system failures.

• Warranty Preservation: DIY work on major components will almost certainly void the manufacturer’s warranty on your panels, inverter, and racking system.

• Code Compliance and Insurance: Electrical work must be permitted and inspected in most areas to be legal and safe. Unpermitted work can void your homeowner’s insurance if a fire occurs. Professionals pull permits and ensure the system meets all local code
