Solar PanelsNeed for Solar Panel Cleaning

Solar Panels are exposed to the environment – sun, wind, dust, rain etc.   Solar panels are very similar to windows, lying flat or at a slight angle which means they get dirty very fast. Pollen, bird droppings, dirt, and dust can build up on solar panels.“Solar Clouding” commonly referred by the panel manufacturers, which means dirty panels and needs to be cleaned on a regular schedule in order to keep them producing at full capacity. There is a 10-15% decrease in solar output when solar panels are dirty.

Solar panels generally require very little maintenance. A few times a year, the panels should be inspected for any dirt or debris that may collect on them. Most manufacturers recommend the cleaning of solar panels every six months. Typically they should be cleaned in March/April when the rainy season has passed and August/September, towards the end of summer. The cleaning services are a necessary part of the system maintenance and also to maintain its warranty.

Having the PV system cleaned will:

  • Maintain your investment
  • Ensure peak performance
  • Extend the life of your product
  • Maintain product warranty.

How to Clean Solar Panels

One can use a garden hose to wash the face of the panels during either the early morning or in the evening. Care should be taken not to spray cold water onto hot panels or there could be a risk of cracking them. There are also automated cleaners, which can be programmed to clean the panels as needed - a good choice if you are in an especially dusty area. Professional solar panel cleaners are also in abundance and can come out periodically to clean them.

Generally the solar panels are dusted gently and then washed using a soft wash brush to lightly scrub the dirt off. One should check with the solar panel manufacturer to know the best way to clean your solar panels. Hard water should not be used for the cleaning. Also check if there is any blockage from the sun like trees or plants. Clean solar panels are worth the effort.

Checking Solar Panel Operation

The only other part of solar panel maintenance is monitoring their energy output and ensuring there are no malfunctions. Check and log the power output on the solar inverters display on a daily or monthly basis. With this data, one can check to see if solar panels are functioning at full efficiency.  Solar panels produce different amounts of power during the year, so keeping a baseline measurement helps.

    The World Goes Solar. Japan’s FiT in July is among the highest in the world. It’s clear that Japan’s FiT will shake the solar market. Now, US has the same options. New solar technology will show in Japan. This is it!
    As you know, earthquake in japan is happening frequently. Floating solar panels installation is one of the best solutions for power crisis in Japan. So you have to reduce vibration to install Floating solar panels. Because, it makes many kinds of problems! Vibrations caused by wind, waves and external forces. New Floating Body Stabilizer for Floating solar panels installation has been created in South Korea. The Floating Body Stabilizers generate drag force immediately when Floating solar panels are being rolled and pitched on the water. Recently, these Floating Body Stabilizers have been used to reduce vibration of Floating Solar Panels in South Korea. You can see New Floating Body Stabilizer videos in YouTube. http://youtu.be/O2oys_YHhCc, http://www.youtube.com/watch?v=nA_xFp5ktbU&feature=youtu.be.

    Thank You, Mr. Kim for your valuable insight about the situation in Japan.
    Japan is already one of the biggest markets globally and has a large solar manufacturing industry, however with the setting of high Feed in Tariff of 52c/KwH, solar demand is set to increase exponentially.
    Germany Solar Feed in Tariff too may see 2% cut each month in 2012.
