Solar panels are an excellent alternative for target homeowners who want to reduce their carbon footprint and energy bills. However, like any other electrical equipment, they may encounter technical problems requiring repair. In this article, we’ll give you an overview of the most common types of breakdowns and how much they can cost to repair.
Type of failure #1: Electrical problems
This is undoubtedly one of the most common problems encountered with solar panels. Electrical problems typically include malfunctioning inverters, damaged cables, or poor connections. Here are some examples of electrical problems and their approximate cost to repair:
Defective inverter: The inverter, which converts solar energy into usable electricity, is likely to fail following a few years. The cost of replacing an inverter ranges between 1000 and 2500 euros depending on its capacity.Damaged cables: Cables exposed to weather and rodents can become damaged over time. Replacing a cable can cost between $50 and $200, depending on the length required and labor cost.Bad connections: Poor connections can cause solar panels to lose performance. Fixing this problem can cost you between $50 and $150, depending on the extent of the damage and the time it takes to find and repair faulty connections.
Failure Type #2: Structural Problems
Structural problems are also quite common among solar panel owners. They typically include damaged brackets, corrosion, or cracked solar panels. Here are some examples of structural problems and their approximate cost to repair:
Damaged media: A support weakened by exposure to bad weather and heavy loads (such as snow) can cause problems for the entire system. The cost of repairing a damaged support varies between 100 and 500 euros, depending on the complexity of the structure and the cost of labor.Corrosion : Metal structures are particularly vulnerable to corrosion over time. If the corrosion is significant, the frame will have to be completely replaced, which will cost between 500 and 2000 euros.Cracked solar panel: Solar panels can crack following impact or excessive wear. Repairing a cracked panel is complicated and expensive, with an estimated cost of between 200 and 800 euros. In some cases, it may be more economical to replace the panel entirely.
Practical advice: prevention and regular maintenance
To minimize the risk of breakdowns and their repair costs, it is essential to carry out regular maintenance on your solar panels as well as visual inspections in order to quickly identify any signs of deterioration. Annual maintenance by a professional will also ensure you maintain optimal performance and extend the life of your solar system.
Failure Type #3: Performance Issues
Even if your solar panels appear to be working fine, they might not produce as much energy as they should due to performance issues such as dirt, shading, or high temperature. Here are some examples of performance issues and their approximate cost to resolve:
Dirt : If the solar panels are dirty (from dust, bird droppings, etc.), their performance will be significantly reduced. Cleaning solar panels generally costs between 25 and 50 euros per panel, depending on the height at which they are installed.Shading: Shadows cast by nearby trees or buildings can reduce the ability of solar panels to produce electricity. Trimming trees around your system can cost between $50 and $500, depending on their size and location.High temperature : Solar panels are sensitive to heat and their performance decreases when exposed to high temperatures. It is not possible to control the outside temperature, but it is possible to improve the ventilation around the solar panels to limit their overheating. This intervention can cost between 100 and 300 euros, depending on the surface area covered by the solar panels and the type of ventilation used.
Type of breakdown n°4: Normal wear and tear and warranty
Solar panels have an estimated lifespan of around 25 to 30 years, but their efficiency gradually decreases over time. Although normal wear and tear is not considered a “breakdown,” it is important to be aware of this development over time. If your solar panels are still under warranty (usually a 25-year performance guarantee), you may be able to have them replaced at no additional cost in the event of a malfunction or significant loss of output.
Practical advice: comparing quotes
Before committing to repairing your solar panels, it is recommended that you compare several offers and quotes to ensure that you are getting the best possible price. Also take into account the reputations and skills of the professionals contacted to guarantee quality work.
Ultimately, the cost of repairing a solar panel system will depend primarily on the type of fault encountered and the labor and materials required to resolve it. Do not hesitate to contact a qualified professional for a complete diagnosis and a personalized quote.
