Frequently Asked Questions
What are the five common problems?
The five common problems are shading and soiling, installation errors, microcracks, inverter faults, and degradation over time. Each issue can reduce output or shorten system life. Regular checks and maintenance help prevent the worst outcomes.
The five common problems are shading, installation errors, microcracks, inverter faults, and aging panels. Regular checks help prevent major losses.
How can I prevent shading?
Trim or relocate nearby obstructions, and consider seasonal panel positioning. Cleaning and routine inspections can reveal new shade sources or debris that reduces performance. A monitoring system can alert you to unexpected drops caused by shading.
Trim trees or adjust angles to avoid shade. Regular checks catch new shade early.
Do installation mistakes matter most?
Yes. Incorrect mounting, wiring, or component mismatches can dramatically reduce efficiency and safety. Always verify mounting torque, wiring gauge, and compatibility with your inverter and racking system.
Poor installation wastes energy and can be risky. Have a pro verify the setup if unsure.
When should I replace aging panels?
Degradation happens gradually, but performance declines can become noticeable well before a panel fails. Evaluate output loss relative to replacement costs and consider a professional evaluation for aging installations.
If performance drops significantly, it’s time to have a pro assess so you know if replacement is right.
What’s the best time to call a pro?
Call a pro if you detect persistent outages, inverter alarms, or visible damage like cracks. A professional can diagnose electrical issues safely and provide a clear repair plan.
If you notice odd outages or alarms, bring in a professional.
