Introduction
The purpose of this article is to answer the question: “Does mold grow under solar panels?” Solar panel installation is becoming increasingly more popular thanks to the tax incentives and subsidies available. As more families switch to solar power, more people are starting to ask questions about the effects of organic growth on the performance of their panels. This article will provide an overview of organic growth and discuss potential causes and effects. We will also look at the best preventative measures to help reduce the risk of problems associated with organic growth.
Do Mold Grow Under Solar Panels?
Organic growth such as mold, mildew, algae, and lichen can thrive under the right conditions. It requires four critical components for organic growth to occur: water, heat, nutrient, and a hospitable surface. On solar panels, the combination of shade, moisture, and warm temperatures is the ideal environment for organic growth to develop and spread.
Examples of organic growth on solar panels are typically seen on the side of the panels that receives little to no direct sunlight. This is because mold and mildew needs a cool, humid environment to thrive. As the temperatures on the panel surface rise above 90°F, it can cause the mold spores to die off.
Potential Causes
Organic growth on solar panels is often caused by porosity in frameless solar panels. Since frameless cells create a larger surface area then the traditional framed cell, there are more areas where organic growth can take root and start to spread. In addition, temperature fluctuations between hot and cold temperatures can create condensation on the surface of the solar cells, which can lead to mold and mildew. Poor design is another potential cause of organic growth. A close inspection of the panels should be done to ensure that the edges of the cells, the connectors, and the installation itself are properly sealed and secure.
Effects of Organic Growth
Organic growth on your solar panels can reduce power output. This is because as organic growth covers more and more of the cells, it absorbs light and reduces the amount of energy being generated. Hot spots are another effect of organic growth on your solar panels. These hot spots can form as the organic growth absorbs light, which causes the temperature of the cells to rise beyond the normal range. This can lead to equipment failure. Lastly, organic growth can lead to water infiltration. As the organic growth absorbs more and more water, it can saturate the cells, which can cause them to fail.
Preventative Measures
Regular inspections should be done to check for organic growth. An experienced installer should inspect the panels and remove any organic growth if necessary. Proper orientation can also help reduce the risk of organic growth on your solar panels. Installing the panel at the correct angle is key to reducing the amount of heat and moisture that can accumulate on the surface. Finally, regular cleaning can also help to reduce the risk of organic growth. This should be done with a soft cloth and mild detergent, taking care to avoid scratching the surface of the cells.
Conclusion
Organic growth on solar panels can have a negative impact on both the performance and the lifespan of your system. It is important to regularly inspect and maintain the panels to ensure they are free of dirt and debris. Proper orientation and regular cleaning can also help reduce the risk of organic growth. Finally, installing a properly sealed and secure solar panel is key to preventing water infiltration and promoting optimal performance.
