Solar panels are a major investment, and keeping them clean is very important for maintaining their efficiency and performance. Over time, dust, debris, bird droppings, and even algae can collect on the surface, blocking sunlight and reducing the amount of energy your panels can produce.
A well-maintained solar system not only performs better but also has a longer lifespan. However, many homeowners are unsure about how to clean their solar panels safely and effectively. Regular solar panel cleaning is an easy and essential job to make sure your solar system is still generating electricity every year. However, if the job seems out of hand for you, do not hesitate to contact professionals like NetZero Builder LLC, as it is better to be safe than sorry!
When to Clean Solar Panels?
Knowing the right time to clean your solar panels is important for keeping them efficient. Ideally, you should clean those panels as soon as any drop in performance is noticed or if the panels are dirty. Sometimes, the first signs are a reduction in the amount of energy that your solar system produces, if it has been operating quite well before. Besides, particles of dust, dirt, and debris on the surface of the panels can turn out to be barriers to sunlight, leading to the reduction in energy absorption.
Moreover, after some weather conditions such as heavy storms, dust storms, or when trees start blooming during the spring, you should check your panels out. Accumulations from these events can impact the performance. If it is common in your area to have birds flying above, you might have to deal with solar panel cleaning more often as bird droppings if not cleared, can be there for a long time. Frequent examinations will make sure that your panels keep producing energy and secure your investment for a long time.
How Often to Clean Solar Panels?
How often you need to clean your solar panels is determined by a number of factors, from the environment and climate to the place where you live. In most areas, twice or once per year is sufficient for keeping the panels reaching the performance level. Nevertheless, some cases may demand more regular work.
For example, if you live in an area with high levels of dust accumulation and construction activities are taking place nearby, there might be a high chance of dirt and debris buildup making it necessary to clean your unit every 3-6 months. In the same way, if you have installed your solar panels in close proximity to trees, where leaves often shed or a considerable number of birds gather, you might want to get rid of animal droppings and organic materials that accumulate quite often by cleaning more regularly.
Additionally, after adverse weather events like heavy rainfall, storms, or snow, you should check the panels for possible debris or damage that might have been left behind. The best solution is the systematic regular solar panel cleaning together with the periodic examination which contributes not only to the panels remaining effective and operational throughout the year but also safety practice.
Solar Panel Cleaning Methods
There are numerous methods for solar panel cleaning and each one comes with advantages and disadvantages. Selection of the most appropriate method is clearly based on such issues as the degree of dirt accumulation, the types of panels and safety precautions.
Soft Washing: This method involves using a soft-bristled brush, mild soap, and low-pressure water to gently remove dirt without risking damage to the panels. It is the safest and most effective option for regular cleaning.
Waterless Cleaning: For light dirt or dust, you can use a dry cloth or brush, which eliminates the need for water. However, this method may not remove stubborn stains or heavier debris.
Air Blowers: Some homeowners use compressed air or leaf blowers to remove loose debris. While effective for light cleaning, it may not be as thorough for heavy grime or sticky substances like bird droppings.
Pressure Washing: While pressure washers can be effective in cleaning dirt, they can also damage panels if not properly used and therefore, this method is not usually recommended.
Each cleaning method has its place, but for most situations, soft washing is the safest and most effective way to keep solar panels in top condition.
What is the Best Way to Clean a Solar Panel?
The best way to clean solar panels is through a method known as soft washing. This approach is both effective and safe for maintaining panel performance without risking damage. Here is how it works:
Gather Supplies: You shall need a soft-bristled brush, a telescoping pole (for hard-to-reach panels), mild soap or a dedicated solar panel cleaner, a hose with a low-pressure nozzle, and a microfiber cloth or squeegee for drying.
Turn Off the System: Always make sure your solar power system is turned off before cleaning to avoid electrical hazards.
Rinse the Panels: Start by gently spraying the panels with water using low pressure to remove loose dirt and debris.
Scrub the Panels: Apply a mixture of warm water and mild soap with the soft-bristled brush. Gently scrub the panels from top to bottom to avoid streaks and make sure of a thorough clean.
Rinse Again: After scrubbing, rinse off all soap residue using clean water.
Dry the Panels: Use a microfiber cloth or squeegee to wipe away excess water, preventing water spots and making sure of a clean, shiny finish.
Soft washing is the safest method for most homeowners, offering a balance of effectiveness and care, especially for preventing scratches or panel damage.
