太阳能板的辐射有害健康吗？

Core Viewpoint - The article addresses the misconceptions surrounding solar panels and their radiation, emphasizing that the radiation emitted by solar photovoltaic components is extremely low and poses no health risks [1][5]. Group 1: Solar Energy Production - In 2024, China's solar cell production is projected to reach 680 million kilowatts, representing a year-on-year growth of 15.7% [1]. - Solar energy systems are increasingly integrated into daily life, with solar panels converting sunlight into electricity through the photovoltaic effect [2]. Group 2: Radiation Emission from Solar Panels - Solar panels do emit electromagnetic waves due to the flow of electric current, but the intensity of this radiation is very low, measured at approximately 0.02 microteslas, which is about 1/5000 of the national safety standard limit of 100 microteslas [4][3]. - The design of inverters used in solar systems includes shielding and filtering measures to keep radiation levels within safe limits [3]. Group 3: Comparison with Household Appliances - Common household appliances also emit low levels of radiation, with measurements showing that devices like computers and microwaves have radiation values well below national safety standards [8][7]. - The article highlights that the radiation from household appliances is primarily due to changes in electric current, which creates alternating electromagnetic fields [6]. Group 4: Types of Radiation - The article distinguishes between electromagnetic radiation (from solar panels and household appliances) and ionizing radiation, noting that the former has low energy and does not cause DNA damage, while the latter has high energy and can be harmful [9][10]. - Electromagnetic radiation is likened to a feather's touch, causing minimal harm, whereas ionizing radiation is compared to a stick hitting, which can cause significant damage [9][10].
