As the popularity of solar photovoltaic power generation continues to grow, more and more homeowners are installing solar panels on their rooftops. With concerns about the radiation from mobile phones, computers, and Wi-Fi, users who have installed or are considering installing solar panels often turn to Huayang Green Building for advice. Will there be radiation from installing solar panels on my rooftop? Is there any radiation at all? Let's explore the detailed explanation below.
Principle of Solar Photovoltaic Power Generation
Solar photovoltaic power generation directly converts sunlight into DC electricity using semiconductor materials, and then converts the DC electricity into AC electricity through an inverter for use. This process does not involve any chemical changes or nuclear reactions, so there is no shortwave radiation associated with solar photovoltaic power generation.
Regarding Radiation: Radiation is a broad term that encompasses various forms, including light radiation, electromagnetic wave radiation, particle radiation, and even heat radiation. Therefore, it is essential to recognize that we are already exposed to different types of radiation in our everyday lives.
What type of radiation is harmful to humans? In general, when people mention "radiation," they refer to radiation that can be harmful to human cells, such as radiation that can cause cancer or genetic mutations. This usually includes shortwave radiation and high-energy particle radiation.
Does a Solar Photovoltaic Power Station Produce Radiation?
Considering the relationship between common radiation sources and wavelengths, do solar panels emit radiation? Solar panels only convert energy within the visible light range directly into electricity and do not generate any additional harmful radiation during this process.
As for the solar inverter, it is a standard electrical device. While it contains IGBTs or transistors and operates at switching frequencies of several kilohertz, all inverters have metal shielding enclosures and comply with globally recognized electromagnetic compatibility certifications.
WiFi vs. Solar Photovoltaic Power Generation: Which Emits More Radiation?
WiFi radiation has long been a subject of criticism, with many pregnant women particularly concerned. WiFi is essentially a small-scale local area network primarily used for data transmission. As a wireless device, WiFi does emit electromagnetic radiation in its immediate vicinity. However, the power output of typical WiFi devices ranges from 30 to 500 milliwatts, which is lower than that of a typical mobile phone (0.125 to 2 watts). Moreover, WiFi devices such as wireless routers are typically situated much further away from users compared to mobile phones, resulting in significantly lower power density of the radiation received. If one is genuinely worried about radiation, it may be more prudent to set aside their phone and minimize exposure to radiation.
Radiation from Solar Photovoltaic Power Generation
Solar photovoltaic power generation converts sunlight directly into DC electricity using semiconductor materials, and then uses an inverter to convert it into AC electricity for consumption. This process does not involve any chemical changes or nuclear reactions, so it does not emit shortwave radiation. Additionally, solar inverters are standard electrical devices equipped with IGBTs or transistors, but they have metal shielding enclosures and comply with globally recognized electromagnetic compatibility certifications.
The environment we live in is filled with radiation, both harmful and harmless. While solar photovoltaic power generation involves radiation, it falls within the range of safe radiation. Therefore, there is no need to worry about radiation from installing a solar photovoltaic power station on your rooftop. In fact, solar panels have become a necessary household addition in many countries.
