As a purpose to convert the planet into a sustainable one or to empower positive change in the world, the investment made in solar panels is one of the best investments one can make. Along with this, one can be prone to save money and money on energy bills.

Solar panels require relatively low maintenance. Therefore, in order to create awareness about it, we have taken the initiative to provide you with guidance by considering certain things in common.

Solar panels are a valuable renewable energy technology, but they can face various challenges. Here are 14 common problems with solar panels and their potential solutions:


When solar panels are partially or fully shaded, their energy production decreases. Solution: Regularly trim trees and objects that cast shadows on the panels, or consider using micro-inverters or power optimizers to mitigate the impact of shading.

Solution: You can trim trees or install shading screens to reduce shading.

Dirt and Dust Accumulation

Dirt, dust, and debris can accumulate on solar panels, reducing their efficiency. Solution: Periodically clean the panels with water and a soft brush or hire professional cleaning services. 

Solution: You can clean your solar panels yourself or hire a professional to do it for you.

Weather Damage

Hail, storms, or heavy snow can damage solar panels. This is a most common solar panel problem. If you are also facing this issue then do not worry down below we provide you the perfect solutions.

Solution: Install panels with sturdy frames and tempered glass to withstand extreme weather conditions.

Solution: Choose solar panels that are designed to withstand the weather conditions in your area. You can also install hail guards or other protection to help protect your solar panels from weather damage.


It can develop in solar panels due to a variety of factors, including extreme weather conditions, manufacturing defects, or impact damage. Micro-cracks can reduce the efficiency of solar panels, but they are usually not a major problem.

Solution: If micro-cracks are not causing any significant problems, you may not need to do anything. However, if the micro-cracks are causing a noticeable decrease in efficiency, you may need to replace the solar panel.

Inverter Failures

Inverters convert DC power from the panels into usable AC power but can sometimes fail. Solution: Regularly monitor the inverter’s performance and have it serviced or replaced as needed.

Solution: If your inverter is not working properly, you will need to have it replaced.

Hot Spots

Malfunctioning cells can create hot spots, leading to reduced efficiency and potential long-term damage. Solution: Use panels with bypass diodes to minimize the impact of a malfunctioning cell.

Solution: To prevent hot spots, you should make sure that your solar panels are properly installed and that the wiring is correct. You can also install thermal fuses to protect your solar panels from hot spots.

Potential Induced Degradation (PID)

PID is a phenomenon that can cause solar panels to lose efficiency over time. PID is caused by a build-up of electric charge on the surface of the solar cells. There is no surefire way to prevent PID, but it can be minimized by installing your solar panels properly and by using high-quality materials.

Solution: There is no cure for PID, but you can slow down the degradation process by installing your solar panels properly and by using high-quality materials. You can also install PID mitigation devices to help protect your solar panels from PID.

Faulty Wiring or Connectors

Poorly connected wires can lead to power losses or even fire hazards. Solution: Ensure proper installation and regular maintenance by qualified professionals.

Solution: Repair or replace the faulty wiring or connectors:


Over time, solar panels can experience reduced efficiency. Solution: Choose high-quality panels with good warranty coverage, and consider upgrading to more efficient panels as technology advances.

Solution: It is important to have your solar panels inspected by a qualified professional. They will be able to determine if your solar panels are aging and recommend any necessary repairs or replacements.

Voltage Fluctuations

Variations in voltage can occur, leading to inefficient power production. 

Solution: Install voltage regulation equipment and use quality charge controllers.

Solution: Ensure the repair of solar panels from qualified professionals.

Lightning Strikes

Lightning strikes can damage solar panels and other components. Solution: Install surge protection devices to safeguard against lightning-induced surges.

Solution: Install surge protectors on your solar system to help protect your solar panels from lightning damage.

  1. Inefficient Angle and Orientation: Incorrect tilt or orientation can reduce solar panel efficiency. Solution: Optimize panel positioning during installation to maximize exposure to sunlight.
  2. Electrical Interference: Nearby electronic devices or power lines can cause electrical interference. Solution: Maintain a proper distance between the solar system and potential sources of interference.
  3. Limited Storage: Solar panels produce energy only when the sun is shining, but energy demand might not align with production. Solution: Invest in energy storage solutions like batteries to store excess energy for later use.

Regular maintenance and proper solar panel installation play significant roles in preventing and resolving many of these issues. Always consult with qualified solar professionals to ensure your solar panel system is well-designed and regularly maintained for optimal performance and longevity.
