late afternoon at least once during spring, autumn, and summer seasons unless unusual events occur. However, during the winter season, solar panels should be cleaned at least once every month due to the difference in the weather during this period.<\/p>\n<p>Despite that this can be taken as a reference, there are other facts that may give you an idea of when it is the right time to clean your solar panels, facts that we will discuss in this article. There are many factors that can reduce the power yields of a solar PV system: shadings, PID, LID, ohmic, thermal, and mismatch losses among others. Soiling is another parameter to consider, and maintenance is the only solution to avoid it. That is why it is deeply important to know when to <a href=\"https:\/\/ecotality.com\/solar-cleaning\/\">clean your solar panels<\/a>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What-Are-Soiling-Losses-on-a-Solar-Panel\"><\/span>What Are Soiling Losses on a Solar Panel?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Soiling losses are attributed to the reduction in solar irradiance to the solar panel due to the presence of a layer of dirt, mud, leaves, dust, snow, or bird droppings that might obstruct a section of the solar panel. These things do not allow the conversion of light into electricity to be carried out effectively. This can radically reduce the power output and energy yields of solar panels in very extreme cases.<\/p>\n<p><picture><source srcset=\"https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/graqfica.webp 596w,https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/graqfica-300x195.webp 300w\" sizes=\"(max-width: 596px) 100vw, 596px\" type=\"image\/webp\"><img src=\"https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/graqfica.png\" height=\"387\" width=\"596\" srcset=\"https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/graqfica.png 596w, https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/graqfica-300x195.png 300w\" sizes=\"(max-width: 596px) 100vw, 596px\" class=\"aligncenter wp-image-778 size-full sp-no-webp\" alt=\"multiple dirty solar panels covered in mud\" decoding=\"async\" loading=\"lazy\"  > <\/picture><\/p>\n<p style=\"text-align: center;\"><span style=\"font-size: 20px;\">(Source \u2013 <a href=\"http:\/\/www.sec.cl\/pls\/portal\/url\/ITEM\/3DBA0C4A4F9827CAE050007F010005E6\" target=\"_blank\" rel=\"nofollow noopener\">Maintenance and Operation Guide of Photovoltaic Systems<\/a>)<\/span><\/p>\n<p>Soiling losses will depend on multiple factors such as location, relative humidity, industrial and mining activities in nearby areas, snow, the absence of cleaning, the presence of dust, sandstorms, or even volcanic ashes from distant volcanos.<\/p>\n<p>Regions across the world such as the Middle East need a constant maintenance in order to compensate the losses attributed to soiling and sandstorms that can radically reduce the performance of a solar array.<\/p>\n<p>As odd as it may sound, the US is not exempt from the presence of dust storms. Actually, in July 2018, Arizona experienced a tremendous sandstorm. Other States such as Nevada, California, Utah, Oklahoma, and Colorado have also experienced sandstorms, unpleasant for both the population and PV systems.<\/p>\n<p>Quantifying soiling losses can be hard, as several factors need to be considered. However, soiling patterns across the world can be classified according to dust intensities in the research performed by M.R Maghami, called <em>Power Loss Due To Soiling On a Solar Panel.<\/em><\/p>\n<p>As soiling concentrates on the solar panel, the losses attributed to this factor increase on a monthly basis and could lead up to 30 % annual losses (and even more in extreme cases). Therefore, it is necessary to develop a maintenance routine in order to maximize energy yields of solar panels and to keep soiling losses around 2% &#8211; 5% annually.<\/p>\n<p><picture><source srcset=\"https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafico.webp 563w,https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafico-300x132.webp 300w\" sizes=\"(max-width: 563px) 100vw, 563px\" type=\"image\/webp\"><img src=\"https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafico.png\" height=\"247\" width=\"563\" srcset=\"https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafico.png 563w, https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafico-300x132.png 300w\" sizes=\"(max-width: 563px) 100vw, 563px\" class=\"aligncenter wp-image-779 size-full sp-no-webp\" alt=\"map of the world chart showing the power loss due to soiling on solar panels\" decoding=\"async\" loading=\"lazy\"  > <\/picture><\/p>\n<p style=\"text-align: center;\"><span style=\"font-size: 20px;\">(Source \u2013 Power loss due to soiling on a solar panel \u2013 M.R Maghami.)<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Signs-That-Indicate-It-is-the-Right-Time-to-Clean-Your-Solar-Panels\"><\/span>Signs That Indicate It is the Right Time to Clean Your Solar Panels<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>After you install your solar PV system you should take a look at the energy yields of the first month period. Depending on your location and the season that you installed the PV system, the energy yields can vary. However, once you have the first complete annual performance of the PV system it is likely to be similar in the next 5 years (solar panels degrade over time, so the performance of year 1 is not the same as year 15).<\/p>\n<p>Keep those numbers for your records and try to check the generation of the solar system on your inverter display at least once every 3 months. If reductions in that period are too different from previous seasons, then it is possible that something is affecting the performance of your PV system. Probably the reason will be either shading of a nearby object or that your solar panels are getting dirty.<\/p>\n<p>Moreover, whenever there are unusual construction sites nearby related to your neighbors&#8217; house upgrades, or to local government projects, it is likely that your solar panels will catch some particles of dust. If the construction takes several days, then it is probable that dust will accumulate further. <a href=\"https:\/\/ecotality.com\/why-are-solar-panels-blue\/\" target=\"_blank\" rel=\"noopener\">Most solar panels are a dark blue color<\/a> so you will notice fairly easily when too much dust has gathered on parts of the solar panel.<\/p>\n<p>Winter is an annoying season for solar panels because snowfalls can continuously leave snow on your roof or within your <a href=\"https:\/\/ecotality.com\/solar-roof-shingles\/\" target=\"_blank\" rel=\"noopener\">solar roof shingles<\/a>. If the few hours of Sun that are available will be completely blocked by snow, then the performance of your solar panels during the winter season will reduce. This doesn&#8217;t mean that you have to go out there to the roof every day to clean your PV array, because <a href=\"https:\/\/ecotality.com\/can-solar-panels-overheat\/\" target=\"_blank\" rel=\"noopener\">solar panels also get hot<\/a> and can melt down the snow by themselves. Nevertheless, whenever you see a strong snowfall outside, keep in mind that your solar panels may need a little help. During the winter season, it is ideal to check on your modules at least once every month.<\/p>\n<p><picture><source srcset=\"https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafio.webp 595w,https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafio-300x159.webp 300w\" sizes=\"(max-width: 595px) 100vw, 595px\" type=\"image\/webp\"><img src=\"https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafio.png\" height=\"316\" width=\"595\" srcset=\"https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafio.png 595w, https:\/\/ecotality.com\/wp-content\/uploads\/2018\/12\/grafio-300x159.png 300w\" sizes=\"(max-width: 595px) 100vw, 595px\" class=\"aligncenter wp-image-780 size-full sp-no-webp\" alt=\"solar panels outside of a home during winter\" decoding=\"async\" loading=\"lazy\"  > <\/picture><\/p>\n<p style=\"text-align: center;\"><span style=\"font-size: 20px;\">Winter Solar Panel Performance and Maintenance (Source \u2013 <a href=\"https:\/\/us.sunpower.com\/home-solar\/solar-cell-technology-solutions\/winter-solar-panel-performance-and-maintenance\/\" target=\"_blank\" rel=\"nofollow noopener\">SunPower<\/a>)<\/span><\/p>\n<p>Rain is a favorable meteorological condition for solar panels. Ideally, your solar provider should have considered in the design to minimize maintenance of the PV system. In order to do so, the <a href=\"https:\/\/ecotality.com\/solar-panel-tilt-angle-calculator\/\">solar installer should at least place the solar panels with a 15\u00b0 tilt angle<\/a> that will allow rainwater to do the dirty work and clean your solar panels.\u00a0 This shouldn&#8217;t be a problem in the US because all locations have latitudes above that angle, but keep it in mind.<\/p>\n<p>Based on the importance of rain, if rain in your area have been scarce or the region is passing through a drought period, it might be a good idea to take a look at the PV system. Moreover, if there has been a long period where you haven&#8217;t <a href=\"https:\/\/ecotality.com\/cleaning\/\">cleaned<\/a> your solar panels, and the rain finally appears, a couple of days later might be good to take a look as well at the PV array.<\/p>\n<p>The reason is that dust can be transformed into dirt when mixed with water, and despite the fact that the rain will clean most of the surface of the solar panel, the remaining dirt could accumulate on the borders and corners of the frames. If they do not incorporate a drainage system (or are frameless) then it will be a spot for the accumulation of moisture and humidity that can lead to other problems such a leakage currents or delamination of the PV cell.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"When-Should-I-Normally-Clean-My-Solar-Panels\"><\/span>When Should I Normally Clean My Solar Panels?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Establishing maintenance routines is the best idea to keep a record and control of the PV system. As mentioned before, it is recommended to clean solar panels at least once during spring and summer seasons unless unusual events occur. Regarding the autumn season, cleaning should be made once or twice due to falling leaves that may obstruct the solar panel. And during the winter season, at least once every month (if the solar panels do not melt the snow by themselves). It is also recommended to clean them once it goes dark outside due to <a href=\"https:\/\/ecotality.com\/can-solar-panels-work-at-night\/\" target=\"_blank\" rel=\"noopener\">how solar panels work at night<\/a>.<\/p>\n<p>Moreover, when you decide to clean your solar panels, keep in mind to do it preferably during early hours (6:00 am \u2013 7:00 am) or during late afternoon (5:00 pm-6:00 pm).<\/p>\n<p>There are two reasons for this. First, you will not obstruct or affect the performance of the solar panels during a productive time, therefore <a href=\"https:\/\/ecotality.com\/how-to-clean-your-solar-panels\/\" target=\"_blank\" rel=\"noopener\">the cleaning procedure<\/a> shall not represent energy losses. And second, solar panels get hot due to energy conversion and due to the ambient temperature. Performing cleaning during midday on hot solar panels under the scorching sun might not be the most pleasant experience.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-d1d6a0f post-rating-section elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"d1d6a0f\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-473e507d\" data-id=\"473e507d\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-48751d1a post-rating elementor-widget elementor-widget-shortcode\" data-id=\"48751d1a\" data-element_type=\"widget\" data-widget_type=\"shortcode.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-shortcode\"><!-- Rate my Post Plugin --><div  class=\"rmp-widgets-container rmp-wp-plugin rmp-main-container js-rmp-widgets-container js-rmp-widgets-container--1024 \"  data-post-id=\"1024\">    <!-- Rating widget -->  <div class=\"rmp-rating-widget js-rmp-rating-widget\">          <p class=\"rmp-heading rmp-heading--title\">        We hope you liked this article.
