As solar energy becomes increasingly popular in Zimbabwe, many homeowners and businesses are investing in solar system installations to harness the abundant sunlight. While these systems are generally reliable, occasional issues can arise. Understanding how to identify and troubleshoot common solar system problems can help you maintain optimal performance and avoid unnecessary costs.
At Taqon Electrico, we are committed to ensuring that our customers get the most out of their solar investments. This guide provides detailed insights into frequent problems faced by solar power users and how to effectively address them.
System Not Producing Energy
SYMPTOMS
- The Inverter display shows an error code or is completely off.
- Energy production is significantly lower than expected.
TROUBLESHOOTING STEPS
Check the Inverter Display:
Look for any error messages displayed on the inverter interface. Refer to the inverter’s manual for the error codes for specific meanings and solutions.
Examine for Obstructions:
Look for new trees, buildings, or dirt and dust that might be shading the panels. Even partial shading can significantly reduce power output leading to lower energy production.
Inspect Connections
Ensure all wiring and connections are secure. Look for any visible signs of damage, wear, or corrosion. Even check for any cable disconnection.
Ensure Proper Orientation:
Make sure the panels are correctly oriented towards the sun. For optimal performance, they should ideally be installed facing the northern side in the Southern Hemisphere. Taqon Electrico can provide expert advice on ideal placement
Inverter Issues
SYMPTOMS
- The inverter frequently trips or fails to operate.
TROUBLESHOOTING STEPS
Reset the Inverter:
Power it down completely, wait a few moments, and turn it back on. This can resolve temporary glitches.
Check for Overheating:
Ensure the inverter is in a well-ventilated location. High temperatures can cause it to shut down. If overheating occurs, consider relocating it or improving ventilation.
Firmware Updates:
Many inverters require periodic firmware updates for optimal operation. Firmware updates are essential for improving the performance of many types of solar inverters. Check the manufacturer’s website for updates and instructions.
Monitor Performance:
Use any monitoring tools or apps the inverter manufacturer provides to track performance and error logs. At Taqon Electrico, we install high-quality solar inverters that support system remote monitoring through apps such as Sunsynk, Growatt, and Phocos. Whenever you experience a problem, you can check the system performance data on the inverter app.
Decreased Energy Production
SYMPTOMS
Daily energy output is lower than usual, affecting your power needs.
TROUBLESHOOTING STEPS
Clean the Solar Panels
Dust, dirt, and bird droppings can accumulate on the surface of the panels. Use a hose and a soft cloth to gently clean the panels, especially after dry, dusty spells.
Inspect for Physical Damage
Look for cracks, chips, or other visible damage on the panels. Damage may require panel replacement or repair.
Evaluate Weather Conditions:
Understand that prolonged cloudy or rainy weather can naturally reduce energy production. Keep an eye on long-term weather patterns.
Monitor System Performance:
Regularly check your energy production and compare it to historical data. A sudden drop in output can indicate an issue that needs addressing.
Battery Backup Problems
SYMPTOMS
Batteries not charging fully or failing to discharge properly.
TROUBLESHOOTING STEPS
Inspect Battery Connections
Check all connections for tightness and signs of corrosion. Clean any corroded terminals.
Assess Battery Health:
Older batteries lose capacity. If your batteries are several years old, consider testing their health or replacing them. At Taqon Electrico we recommend that you install the best solar battery brands with longer warranty periods. We offer the best and most long-lasting lithium-ion solar batteries that include Dyness, Deye, and Pylontech lithium batteries with a 5-year warranty period.
Monitor Charge Levels:
Ensure that the charge controller settings are appropriate for your battery type. Misconfigured settings can lead to improper charging or discharging.
Evaluate Energy Consumption:
Make sure your energy usage aligns with the capacity of your battery system. Excessive loads can strain the batteries and lead to operational issues.
Electrical Issues
SYMPTOMS
Flickering lights, tripped circuit breakers, or blown fuses.
TROUBLESHOOTING STEPS
Inspect Wiring:
Check for damaged or frayed wiring. Damaged wiring can cause short circuits or energy losses.
Examine Circuit Breakers:
Ensure that circuit breakers are functioning properly and not overloaded. If they trip frequently, consider consulting an electrician for an assessment.
Evaluate Load Management
Distribute electrical loads evenly across circuits to prevent overloading.
System Maintenance Issues
SYMPTOMS
System components, such as inverters or wiring, show signs of wear and tear.
TROUBLESHOOTING STEPS
Regular Maintenance Checks:
Schedule annual maintenance with a qualified technician to perform comprehensive inspections and address potential issues. Taqon Electrico conducts regular solar system maintenance checks and provides a detailed report to avoid unnecessary issues that could have been addressed with proper system maintenance service.
Keep Records:
Maintain a log of all maintenance activities, including inspections, cleaning, and repairs. This can help identify patterns or recurring issues over time.
Educate Yourself:
Stay informed about your system’s components and best practices for maintenance. Knowledge is key to preventing problems. Ask your installers to teach you about your system and stay informed in case of emergencies.
Conclusion
Troubleshooting your solar system can feel overwhelming, but with the right knowledge, many issues can be resolved without professional help. Regular maintenance, vigilant monitoring, and prompt action when issues arise will ensure your system operates efficiently and effectively. If problems persist or if you encounter complex issues, don’t hesitate to contact a professional for assistance.
