If you’re a property owner asking, can I pressure wash solar panels, you’re not alone! This is a common question asked by solar owners and those considering investing in solar. After all, cleaner panels absorb more sunlight, so they create more power. On the other hand, you don’t want to damage those panels either.
Solar panel manufacturers typically do not recommend pressure washing. This process might damage the panels and electrical components. However, you can use low-pressure rinsing and cleaning products designed for solar panels if needed.
To find out more about keeping your solar panels clean and working effectively, keep reading. Also, remember to discuss your panels with a solar installation contractor near you. They can offer added expertise when it comes to ensuring your panels are in good condition.
Pressure washing solar panels is generally not recommended by manufacturers and installers. Power washing can risk damage to the panels and their attached electrical components.
Also, note that solar panels are designed to be weather-resistant and self-cleaning to a certain extent. In fact, rain offers natural cleaning for solar panels. However, if you find that your panels are particularly dirty and you want to clean them, note some guidelines to follow after your solar panel installation:
Check the manufacturer's guidelines and recommendations for cleaning your specific solar panels. Some manufacturers might provide instructions on how to clean their panels safely. This might include a gentle brushing or using certain products designed for solar panels.
If you need to clean your solar panels, opt for gentle cleaning methods. Use those that don't involve high-pressure water. For instance, you might opt for a hose with a gentle spray nozzle or a soft brush with a long handle. These can help remove dust, debris, and light dirt.
If there are stubborn stains or dirt buildup on the panels, use a mixture of water and a mild, biodegradable soap. Apply the mixture with a soft cloth or sponge and rinse with water afterward. You can even use a small squirt of dishwashing liquid in water. However, ensure it doesn’t include added lotions or other oily products.
If your panels are in a shaded area or the weather is cool, consider using warm water. Warm water can help dissolve dirt and grime. This doesn’t mean hot water as this can potentially damage glass panels. You also don’t want to waste power heating water when it’s not necessary!
Do not use abrasive or harsh cleaning chemicals on solar panels. These can damage their surfaces and interfere with their efficiency. Some harsh chemicals and products can also run off to the property’s roof, risking damage to shingles and tiles.
Remember that the goal of cleaning solar panels is to ensure they are operating at their optimal efficiency. If you're unsure about the best cleaning approach, consult with a professional who specializes in solar panel maintenance.
Hosing off solar panels with a gentle stream of water is a good way to clean them. Using a gentle hose is even needed if the panels have accumulated dust, dirt, or debris. However, there are a few important considerations to keep in mind even with a garden hose:
