Is photovoltaic energy production really a clean energy source?

1. The definition of clean energymeans that no harmful substances are emitted during the production and use process. This harmful substance mainly concerns sewage, waste gas and solid waste, namely the industrial “three wastes”.

Photovoltaic power generation refers to a method of generating electricity that uses photovoltaic cells to collect sunlight and transform it into electrical energy. Photovoltaic power generation is a high-level official name, and the popular saying among the people is solar power generation.

Photovoltaic power generation is also called photovoltaic effect, which is a change from the term "photovoltaic effect". It refers to the physical change process of converting sunlight into electrical energy (volts): sunlightit shines on the solar panel and is absorbed by the interface layer. Positive and negative electrons move between different specific parts and generate a potential difference. actually done in practice. The electrical energy necessary for life.

The production of photovoltaic energy is undoubtedly a clean energy: its production process does not use fuel and does not emit any substances, in particular greenhouseand other waste gases. produces noise, has a large amount of resources, is widely distributed, does not pollute the environment and can be used almost infinitely. Therefore, the state vigorously promotes this new energy technology and provides policy support for subsidies.

Does photovoltaic power generation produce electromagnetic radiation? to have! If there is electromagnetic radiation, alors there is pollution. How can this be called clean energy?

Wherever there isalternating currentthere is electromagnetic radiation. The difference is in the amount of radiation.

Photovoltaic power generation is a physical change process that converts light energy into direct current and then alternating current. Direct current has no electromagnetic radiation. Electromagnetic radiation from photovoltaic power generation mainly comes from photovoltaic inverters. But if you compare the amount of electromagnetic radiation from a photovoltaic inverter to that of household appliances, the amount of radiation coming from the same laptop is about the same and much less than the amount of electromagnetic radiation coming from a dryer -hair, an induction cooker and a refrigerator. you use itsem almost every day. We can therefore say that this amount of radiation is almost negligible.

2. There is no need to avoid it. Pollution definitely exists in the battery panel production process.

Production refers to the activities and processes that humans engage in to create social wealth. Why do humans produce? The reason is that the available natural materials cannot meet the desired needs. In the process of transforming one substance into another substance through physical or chemical changes, harmful emissions of "three wastes" are almost inevitable. In other words, this emission is pollution. What we need to do is use scientific means to reduce the emissions of these harmful substances as much as possible.

Electricity production Photovoltaics is a systemof electricity production.

Photovoltaics is a photovoltaic energy production system. Electricity production system that uses the photovoltaic effect produced by semiconductor materials to convert energy from solar radiation in electrical energy. The energy generated by the photovoltaic power generation system is a very safe, clean and renewable energy that will not harm the ecology or pollute the environment during the photovoltaic power generation process.

Photovoltaic power generation systems rely on solar energy to generate electricity, and current photovoltaic power generation systems can be divided into grid-connected and in independent photovoltaic systems.

Using photovoltaic systems to produce electricity has many advantages, such as the ability to providenormal power supply in harsh weather conditions and environments, high safety performance and long service life. However, photovoltaic energy production also has many disadvantages: its initial investment cost is very high and technical training is necessary before its use.
