Shading
Obstructions such as trees, buildings, or nearby structures can cast shadows on solar panels, reducing their exposure to sunlight and thus decreasing energy production.
Dirt and Debris
Accumulation of dirt, dust, bird droppings, or other debris on the surface of solar panels can block sunlight and reduce their efficiency.
Faulty Components
Issues with individual components like inverters, cables, connectors, or junction boxes can disrupt the flow of electricity within the system, leading to decreased performance or complete system failure.
Panel Degradation
Over time, solar panels may degrade due to exposure to environmental factors such as temperature fluctuations, moisture, or UV radiation, resulting in a gradual decrease in energy output.
Inverter Failure
Inverters are critical components that convert the DC electricity generated by solar panels into usable AC electricity for household appliances. Inverter malfunctions or failures can significantly impact system performance.
Poor Installation
Improper installation practices, such as incorrect panel orientation, suboptimal tilt angle, or inadequate mounting hardware, can compromise the efficiency and longevity of solar panel systems.
Wiring Conditions
Faulty wiring, loose connections, or inadequate wire gauge can lead to voltage drops, overheating, or electrical hazards, affecting the overall performance and safety of the system.
Weather Conditions
Extreme weather events such as hailstorms, heavy snowfall, or high winds can damage solar panels or associated components, impairing their functionality and output.
Ageing Equipment
As solar panel systems age, the efficiency of components may decline, necessitating regular maintenance, repairs, or eventual replacement to maintain optimal performance.
System Design Flaws
Poor system design, including improper sizing, mismatched components, or inadequate ventilation, can result in inefficiencies and reduced energy production over time.
Regular inspection, maintenance, and timely troubleshooting can help address these issues and ensure the continued effectiveness of solar panel systems.
Here are some Top Troubleshooting Tips you can try to get your system back online!
Check your consumer unit or solar PV board to ensure all the fuses are switched on.
Check to see if all your DC and AC isolators are in the on position.
Check your solar generation meter daily and take readings. Compare the current energy production of the solar system with historical data or expected performance levels. A significant decrease in output may indicate an issue with the system.
Has the CT Clamp been removed from the cabling near your consumer unit?
This can be located near your Mains Inlet. This is very common when having a Smart Meter installed or when you are having any additional electrical work done on your property.
Check the display panel or indicators on the inverter to verify that it is operational and not displaying any error codes or warnings. Refer to the manufacturer’s manual for troubleshooting guidance if needed. You may be able to find this on the internet.
Have you spoken to the Company that installed your system? If they have ceased trading check your manufacturer’s warranties as you may still be covered?
Finally, before calling us, you may want to try and reset your system. If you are unsure of how to do this you can find our standard Shut Down and Start-up Solar PV procedure at www.rgeg.co.uk/shutdown/
