What Can Go Wrong With Solar Panels?

Solar panels are an incredible source of renewable energy, harnessing the power of the sun to generate electricity. As more and more homeowners and businesses adopt solar panels, it is essential to understand the potential issues that can arise. In this article, we will delve into what can go wrong with solar panels and provide answers to frequently asked questions.

1. Panel Damage:
Solar panels are designed to withstand various weather conditions, but they can still get damaged. Hail, falling branches, or even heavy snowfall can cause cracks or breakage in the panels. Additionally, poor installation or maintenance can also lead to physical damage.

2. Inverter Failure:
Inverters are a crucial component of a solar panel system, converting the direct current (DC) generated by the panels into alternating current (AC) usable by household appliances. Inverter failure can occur due to manufacturing defects, age, or inadequate maintenance. If your inverter fails, your panels will stop producing electricity.

3. Reduced Efficiency:
Over time, solar panels can experience a decrease in efficiency. Factors like dust, dirt, bird droppings, or leaves can accumulate on the panels, reducing their ability to absorb sunlight effectively. Additionally, shading caused by nearby buildings, trees, or new constructions can also impact the efficiency of your panels.

4. Wiring Issues:
Wiring problems can occur during installation or as a result of rodent damage, extreme weather conditions, or poor maintenance. Faulty wiring can cause power fluctuations, shorts, or even fires. Regular inspections and maintenance can help identify and resolve wiring issues promptly.

5. Inadequate Performance Monitoring:
Monitoring your solar panel system’s performance is essential to ensure it functions optimally. However, if monitoring equipment is not installed or not working correctly, you may miss out on identifying potential issues. Faulty monitoring can result from technical glitches or improper installation.

6. Grid Connection Problems:
Solar panels are typically connected to the electrical grid, allowing excess electricity to be fed back into the grid. However, issues can arise with the connection, such as loose wires, faulty connections, or grid outages. These problems can prevent your panels from functioning correctly or even pose safety risks.

7. Premature Aging:
While solar panels are designed to last for decades, premature aging can occur due to various factors. Extreme weather conditions like intense heat or frequent hailstorms, poor quality materials, or inferior installation can all contribute to the premature degradation of solar panels.


1. How often should I clean my solar panels?
Cleaning frequency depends on your location and environmental conditions. Generally, it is recommended to clean panels every 6-12 months. However, if you notice a significant decrease in efficiency, it may be necessary to clean them more frequently.

2. Can I repair a cracked solar panel?
In most cases, cracked panels cannot be repaired and will need to be replaced. A cracked panel can cause power fluctuations and reduced efficiency, impacting the overall performance of your solar system.

3. How long do solar panels last?
Solar panels are designed to last 25-30 years or more. However, their efficiency may decline slightly over time. Regular maintenance and proper care can help extend their lifespan.

4. Can I install solar panels myself?
While it is possible to install solar panels yourself, it is highly recommended to hire a professional installer. They have the expertise and knowledge to ensure proper installation, maintenance, and compliance with local regulations.

5. What should I do if my inverter fails?
If your inverter fails, contact your solar panel provider or a qualified technician. They will assess the issue and either repair or replace the inverter as necessary.

6. Will solar panels work during a power outage?
In most cases, solar panels will not work during a power outage unless you have a battery storage system. This is to prevent sending electricity back into the grid, which can pose a safety risk for utility workers.

7. Are solar panels covered by insurance?
Solar panels can be covered under your homeowner’s insurance policy. However, it is essential to review your policy and ensure you have adequate coverage for any potential damages or issues that may arise.
