Proper application ensures that the oil uniformly coats the panel surfaces, providing maximum effectiveness. After applying the oil, a gentle wash with a soft sponge or microfiber cloth can aid in removing the residual dirt, thus restoring the panel’s clarity. Another benefit of silicone oils is that they are often non-toxic and safe for the environment, making them an appealing choice for both residential and commercial solar users.
BIODEGRADABLE OILS
Biodegradable oils have gained traction in recent years due to their eco-friendliness. They are specifically designed to break down naturally without harming the ecosystem, making them an ideal solution for environmentally-conscious cleaning practices. Besides being environmentally safe, these oils can effectively remove dirt, grease, and grime, significantly improving the light exposure of solar panels.
When selecting biodegradable oils, it is critical to ensure that they are manufactured from renewable resources. Oils derived from plant sources can provide excellent cleaning power while also being gentle on the environment. Conducting thorough research on available products can yield optimal results. Another important aspect to consider is user safety; many biodegradable options are less toxic compared to their conventional counterparts, reducing health risks during handling and application.
MINERAL OILS
Mineral oils are often chosen for their affordability and accessibility. They are derived from petroleum sources and are widely available across numerous retailers. While some might argue that mineral oils are less effective than silicone or biodegradable options, they still provide satisfactory cleaning results when used appropriately. Additionally, they can help dissolve sticky residues and provide a slippery surface that makes cleaning easier.
However, the use of mineral oils does come with environmental considerations. These oils can pose a risk of pollution if not disposed of properly.
