solar energy generationAfter the system is installed, the PV modules require regular inspection and maintenance, especially during the warranty period. To ensure optimum performance of components, the following maintenance measures are recommended:
Appearance Observation Please carefully inspect the components for appearance defects. Focus on the following points:
1. Whether the component glass is damaged;

Germany has announced that it will abolish nuclear power in 2022, following the Fukushima nuclear leak in Japan. After abandoning nuclear, Germany officially plans to "abandon coal".

On the morning of January 26, local time, after 20 hours of overnight talks, the German Coal Exit Committee (hereinafter referred to as the "Committee") announced that it will close all coal-fired power plants by 2038.

In recent years, household photovoltaics have developed rapidly, but the topic of photovoltaic "safety" is often pushed to the forefront. Photovoltaic "safety" includes two aspects, one is the personal safety of construction personnel during installation, and the other is the safety of photovoltaic systems. Equipment safety (this is also related to the safety of life and property of installation users in the future). Safety is no trivial matter. From installation and construction to later operation and maintenance, it is necessary to pay attention to it at all times. It is necessary to eliminate possible safety hazards in time.

The Sun can generate systemIt is divided into off-grid power generation system,Grid-connected power generationSystem and distributed generation system:

 1, the off-grid power generation system is mainly composed ofsolar cell module, controller,batterycomposition, such as the output power supply is AC220Vor110V, also need to configure the inverter.

 2,Grid-connected power generationThe system is that the direct current generated by the solar modules is converted into alternating current that meets the requirements of the mains grid through the grid-connected inverter and then directly connected to the public grid.

First, the classification of photovoltaic systems

Photovoltaic systems are mainly divided into grid-connected systems and off-grid systems according to different types, and grid-connected systems are divided into low-voltage grid-connected systems and high-voltage grid-connected systems according to different voltage levels. This article mainly considers the low-voltage grid-connected system that has the most contact with the general public. system.

Friends often ask how much capacity photovoltaic power plants should be installed in their homes. In fact, many friends outside the photovoltaic industry have fallen into a misunderstanding: thinking that the size of photovoltaic power plants is related to household appliances.

In fact, to put it simply, the photovoltaic power station will not only supply power to a certain electrical appliance, but will supply power to the entire family. The photovoltaic power and the electricity of the national grid will supply power to the family together!

It has been a consensus in the industry that photovoltaic power plants can greatly increase power generation after cleaning. How to clean the photovoltaic power station? I have referenced some literature and sorted out several cleaning solutions for photovoltaic power plants, and see which one is suitable for your photovoltaic power plant.

The photovoltaic module processing technology is composed of multiple processes such as cell inspection, cell single welding, cell string welding, module stacking, module lamination, installation of frame and junction box, finished product testing, and packaging and storage. Each process is interlinked, so the level of craftsmanship of each process directly affects the quality and grade of the product.

Distributed roof survey is the preliminary work of the project. Through on-the-spot survey and communication with roof owners, the collection of relevant information can prepare for the preliminary design of the next technical plan and the analysis of the project investment income. Various roofs may be encountered in the actual survey, and the owner will also raise technical and business issues such as the feasibility of roof construction, installed capacity, support installation method, investment income, cooperation mode, etc. Taking the color steel tiles and concrete industrial building roofs that are widely used in distributed power stations as the object,

Photovoltaic power generation refers to the power generation method that directly converts solar radiation into electrical energy. Photovoltaic power generation is the mainstream of solar power generation today. Therefore, solar power generation is often referred to now as photovoltaic power generation.

Photovoltaic distributed generation is a new type of power generation and comprehensive utilization of energy with broad development prospects. It promotes the principle of nearby power generation, nearby grid connection, nearby conversion, and nearby use, which can not only effectively improve the power generation of photovoltaic power plants of the same scale At the same time, it also effectively solves the problem of power loss in boosting and long-distance transportation. However, distributed generation also puts forward strict requirements on how to maximize solar power generation and how to ensure grid security, and the functionality and stability of photovoltaic inverters in this process are also extremely critical. Distributed power generation follows the principles of adapting measures to local conditions, clean and efficient, decentralized layout, and nearby utilization, making full use of local solar energy resources to replace and reduce fossil energy consumption.
