But now the real question is – how to clean solar panels safely without harming them. Attempting to clean the panels without proper information can have potential risks of damaging the panels altogether. Usually, instructions for maintaining solar panels are mentioned in the manual provided by the manufacturer. However, if you are looking for a detail step-by-step process and in-depth clarifications, then read this article thoroughly. Here, in this article, we are going to explore everything related to cleaning solar panels for your reference.
Is it Really Necessary to Clean Solar Panels?
Most cases, your solar panels won’t need to be cleaned often if at all. Anything that collects dirt (such as pollen or dust) will be washed away the next time it rains. However, there are times when it may be a good idea to clean your solar panel. It’s worth cleaning your solar panels if you have a lot of bird droppings. Rain might not be able to wash them away very easily so it’s a smart idea. You might also need to clean your panels if there are droughts in your area.
How to Clean Solar Panels
There are two options for cleaning your solar panels: do it yourself or consult a professional. Many solar companies offer this service for a charge. It might be offered as an annual maintenance service or suggested that you have it done whenever they install your product. If you are interested in making it your own, you will usually have everything you need at home. It will usually only require a hose and some soap.
Step 1 – Turn off the Complete System
Before you begin cleaning the Solar Panels you need to make sure that all power connections have been disconnected. It is dangerous to continue cleaning a Solar Panel that is still in use. You will need to shut down any DC systems in your home. In the case of AC systems, it is enough to shut down the main solar supply switch.
Step 2 – Disconnect Gutters or Rainwater Collections
It is important to disconnect rainwater tanks that are being used for rainwater collection. It is crucial to make sure that the water collected does not contain any run-off. Block any gutter pipes on the roof. It can become clogged by the debris and dust that may have been accumulated while cleaning the solar panels.
Step 3 – Pick a Cool, Mild Time of Day
You should clean your solar panels on your roof at a cool, mild time of day. This is because solar panels’ glass can get very hot from direct sunlight. If you wash the panels with water, the glass can crack easily. Even if the glass isn’t cracked, it can be damaged by the rapid evaporation water. You can also clean the panels on a cool, mild day, since no one enjoys working in the heat of the sun.
STEP 4 – Dusting
Solar panels can become clogged with leaves, bird poop, dust, and other debris. Rain may clear some of the debris, but it won’t remove all. It can also leave behind dirty residue after the puddles dry. To begin the cleaning process, remove any debris by gently brushing with a soft-bristled instrument. If the soft brush is attached with a telescopic extension pole with a threaded tip, hook, this can be done from ground level. Some poles reach 24 feet. An extension ladder is required to reach solar panels and brush without an adequate extension pole. Safety precautions include wearing a hard hat, harness, and climbing on the roof. It is best to start by gently brushing solar panels. If there is a lot of material on the panels, mixing water with it immediately could cause spreading and smear. Brushing helps to break down some of the material and makes the cleaning process easier. To keep your hands safe and clean, wear work gloves
STEP 5 – Cleaning with Water
Solar panel cleaning is made easier by water. After the dry debris has been removed by brushing, you can use a garden hose to remove any remaining dirt from solar panels. While it may seem tempting to spray solar panels with water to speed up the process, high-pressure cleaning can cause fine cracks to their surfaces. This will cause future problems and reduce the efficiency of your solar system. Non-compliance of manufacturer specifications regarding solar panel maintenance may result in the cancellation of existing warranties. It is important to remove any hoses with high-pressure attachments before cleaning solar panels. This step requires careful and deliberate spraying of each solar panel. A telescopic hose-wand might be able to help if a garden hose isn’t flexible enough to spray the panels evenly. These hose wands have a stronger grip than a garden hose.
STEP 6 – Scrubbing Away Tough Stains
After removing most of the debris, you can give extra attention to problem areas with a sponge, cloth, or squeegee. It is best to use a gentle, repetitive cleaning motion with patience. Aggressive scrubbing can cause damage to the panels. Even safe cleaning products can still be harmful to solar panels. Water is the best cleaner for solar panels, especially if it has been deionized and distilled. Water that has been deionized or distilled attracts other chemicals making it more effective for cleaning. Deionized water or distilled water may not be available. A water softener can be used to improve the water’s cleaning power. A squirt with gentle dish soap mixed in one part vinegar to eight portions water can be used to clean stubborn areas. Make sure to use soap sparingly. If not, the soap residue attracts dirt and cause streaky solar panels. This can not only make the panels less attractive, but it can also cause problems with their functionality.
STEP 7 – Observing the Changes
Homeowners should examine their energy bills before and during cleaning to determine the impact of solar panel cleaning. Because they have maximum solar exposure, clean solar panels will cost less to run.
STEP 8 – Contact a Professional Solar Panel Cleaner
If you are experiencing low energy efficiency even after the solar panels, then may be its time to contact a professional for more complex cleaning and maintenance requirements. Are solar panels’ efficiency affected by dirt and other debris? What is the impact of dirt and debris on solar panels? Yes, and no. It’s not that much. Yes, dirt and other debris can reduce the amount of sunlight that is able to convert light into energy. The effect on efficiency is minimal – perhaps 5% to 5%. This could translate to a loss of about $20 in your monthly energy bill for a 5kW solar system. It doesn’t matter if it is monthly or all year. Even if you are in areas that have been experiencing drought, it will eventually rain and everything will be washed away. It might even not be worth the effort to clean it all the first time.
How to Clean My Solar Panels?
You must remember one important point before you start cleaning your panels:
Don’t scratch or damage the glass. There are many different models of solar panel models. It is a good idea to verify with the manufacturer of your product for specific cleaning instructions. You can choose to clean in the evening, morning, or cool days. It’s not a good idea to burn yourself by the heat of hot panels during a sunny day. Do not splash cold water onto a hot surface of glass. This can cause cracks from sudden contraction. To get rid of any traces of dirt, use a squeegee. Do not step on your panels as it can cause damage and premature failure. Avoid using bristles with sharp edges as they can scratch the solar glass. You might find oily stains on your panels if you live near an airport, or along a route used by trucks. You can remove these stains with a rag or some isopropyl alcohol.
