The conversion efficiency of solar photovoltaic modules is usually in the range of 20%, which will be reduced due to the accumulation of dust, dirt, pollen, and other particles on the solar panels collectively referred to as pollution. "In high dust/pollen or desert areas, dirty solar photovoltaic modules can reduce the power of solar photovoltaic modules by up to 30%," said Seamus Curran, associate professor of physics and director of the Institute of Nano Energy at the University of Houston. Solar photovoltaic modules are the design, engineering, and assembly of nanostructures. So what harm has happened to solar photovoltaic modules in recent years? Let's take a look together next.

Here is the content list:

  • Solar photovoltaic module cleaning

  • Fire accidents of solar photovoltaic modules

  • The failure rate of solar photovoltaic modules

Solar photovoltaic module cleaning

As of 2019, paying for clean solar photovoltaic modules is a good investment in many regions. However, in some areas, cleaning is not cost-effective. In California, as of 2013, the economic loss caused by pollution is rarely enough to guarantee the cost of cleaning solar photovoltaic modules. On average, the overall efficiency lost by solar photovoltaic modules per day is slightly less than 0.05%.

There are also occupational hazards in the installation and maintenance of solar photovoltaic modules. Bird's nest and other debris may get stuck under the solar photovoltaic module, which may cause system interruption, if the connection is loose, it will cause a fire, or it will only cause the solar photovoltaic module system to degrade over time.

Fire accidents of solar photovoltaic modules

A UK study from 2015 to 2018 investigated 80 fire incidents related to solar photovoltaic modules, of which more than 20 were "serious fires" directly caused by the installation of solar photovoltaic modules, including 37 home buildings and 6 solar farms. In 1/3 of the incidents, the root cause has not been determined, and most of the others are caused by improper installation of solar photovoltaic module failure rate, solar photovoltaic module failure rate products, or design issues. The most common single component that causes a fire is a DC isolator.

The failure rate of solar photovoltaic modules

A study by kWh Analytics in 2021 determined that the median annual degradation of solar photovoltaic modules for residential and non-residential photovoltaic systems were 1.09% and 0.8%, which were almost twice the previous assumptions. The PVEL module reliability study found that the failure rate of solar photovoltaic modules is on the rise, 30% of manufacturers encounter solar photovoltaic module failure rates and junction box-related safety failures (increased from 20%) and 26% of the bill of materials solar photovoltaic module failures Rate failure (increased from 20%).

To reduce the failure of solar photovoltaic modules, the manufacturer of Anhui JF Solar Technology Co., Ltd. (JF Solar) conducts a large number of tests during the production of solar photovoltaic modules, and provides regular cleaning warranty services, and is responsible for consumers.
