    Solar Panel Cleaning Service

    Why Solar Panel Cleaning Is Important?

    Efficiency loss can reach up to 25 percent, but some reports bring the number as high as 30 percent for consumers who never clean their system.

    Due to leaves, bird poop and airborne particles (from dirt and pollen) your solar panels can become dirty and can cause great loss on your solar system investment.

    Dirty panels mean power loss — grime and debris reduce the ability of the solar array to perform at full capacity.

    A solar array is made up of several solar modules wired together, and each solar module is made up of solar cells all mounted collectively in a frame. Solar cells, in turn, are made of semiconductor materials, such as silicon. One side of a solar cell is positive, the other negative. When sunlight hits a solar cell, it excites the electrons in the semiconductor material, and it’s this energy that can be captured as electricity. If the cells aren’t clean, then less sunlight is able to be absorbed and less electricity is generated.

    Just a sample calculation on how much dirty panels can cost your 5KW system.

    Per day average sunlight hour = 4.9

    A 5KW system with full efficiency generates per hour = 5000Watt

    So, a 5KW system can generates 24.5KW electricity per day which is worth $700 per quarter at that rate.

    If due to non cleaning of the solar panels the efficiency get reduced up to 25%, that means you will be losing $176 per quarter and in a year you would be losing some where around $705 and which is really a huge amount of return that you will be losing from your solar system investment.

    So, now we can see how important is to go for solar panel cleaning once in a year to maximize return on investment.

    Why Professional Cleaning, Why Not Self Cleaning Of The Solar Panels?

    Homeowners with small solar systems may choose elbow grease as their preferred cleaning method. Solar panels, like windows, can be cleaned with warm water and dish washing soap to remove any dirt or residue. When you wash them, you’re washing the glass surface and the frame of the panel.

    Sweat equity has its downside, though, and manually cleaning solar panels can come with risks. First, you (or the person who is doing the cleaning) risk personal injury. If you’re not comfortable on your roof, consider your personal safety before ascending a ladder.

    Also, while soap and water won’t hurt your solar panels, you still run the risk of damaging them (remember this is an electrical system you’re cleaning) and need special cleaning agents to clean them without hampering the base material of the panels or even your roof if you don’t know what you’re doing. Some things are best left to professionals.

    A photovoltaic (PV) system performs best with completely unobstructed access to the sun’s rays for most or all of the day. Even something as seemingly inconsequential as a residue layer can affect the performance of your panels, while bigger spots & obstructions can have a much greater impact that is disproportionate to their size.

    On top of cleanliness, there are numerous other issues that may crop up over a system’s lifetime that may go unnoticed, especially when seen by an untrained eye. For example, a panel may have developed cracks as a result of hail or other falling objects, or parts of the racking may have come loose.

    Why Solar World For Professional Cleaning?

    With 7 years of solar energy system industry we know the complete in and out of any small or large solar power system and we know exactly where it can go wrong when efficiency is decreasing to help you protect your investment.

    How Often Solar Panels Need Cleaning?

    Its obvious that system owner might have seen the solar panels while installing and that could be last time. Most of the owners don’t think or understand that the panels might need cleaning and even forgets about the panels after installing as those are not on clear eye sight.

    We at solar world recommend every solar power system to go for professional cleaning once in six months or at least once in a year to protect their hard earned investment and maximize return.

    Regular checks can also prevent cracks or fire risks from developing into something worse – but you’ll need to know what you’re looking for in order to identify these issues in the first place.
