Protect your solar panels against hotspots
Preventing hotspots? Monitoring and battery storage make the difference
Solar panels are an efficient and sustainable source of energy, but like any technology, they can encounter issues. One of the lesser-known yet impactful phenomena is the occurrence of so-called hotspots. A hotspot is a localised overheating within a solar panel. This happens when one part of the panel underperforms - for example due to shading, dirt or a defect - while the rest of the panel continues to generate energy. The weaker cell then acts as a form of resistance, causing heat to build up.
What is a hotspot?
The consequences should not be underestimated. Hotspots can lead to power losses, accelerated wear and, in extreme cases, permanent damage to the solar panel. Over time, this can significantly reduce the lifespan of the entire installation.
The causes of hotspots are varied. Shading, contamination and microcracks are often the trigger, but poor electrical connections can also contribute to the problem. Because solar panels are usually connected in series, one weak link can affect the performance of an entire string.
Monitoring and battery storage as the key to efficiency
This is where smart monitoring and data-driven insights make a real difference today. By quickly detecting irregularities and performance gaps, action can be taken before lasting damage occurs. Monitoring not only helps identify hot spots, but also enables the continuous optimisation of your entire installation’s performance.
When combined with battery storage, this approach becomes even more powerful. By storing energy locally and managing it intelligently, you can avoid peak loads and excessive stress on your installation, factors that can indirectly increase the risk of hot spots. In addition, battery storage reduces the need to inject energy into the grid, allowing you to use your solar energy more flexibly and with greater control.
In short: hot spots are often invisible issues with visible consequences. By investing in monitoring, data and battery storage, you not only protect your installation, but also improve the performance and lifespan of your solar energy system.
