Photovoltaic power generation: let sunlight help you create wealth

Photovoltaic power generation refers to the use of solar photovoltaic cells to directly convert solar radiation into electrical energy. Photovoltaic power generation is the mainstream of solar power generation today, so what people usually refer to as solar power generation now mainly refers to photovoltaic power generation.

Distributed photovoltaic power generation specifically refers to the construction of photovoltaic power generation facilities near user sites, with the operation mode being self consumption on the user side, excess electricity connected to the grid, and characterized by balanced adjustment in the distribution system.

Distributed photovoltaic power generation follows the principles of adapting to local conditions, clean and efficient, decentralized layout, and nearby utilization, fully utilizing local solar energy resources to replace and reduce fossil energy consumption.

Distributed photovoltaic power generation is a new and promising way of power generation and energy comprehensive utilization. It advocates the principles of nearby power generation, nearby grid connection, nearby conversion, and nearby use. It can not only effectively increase the power generation of photovoltaic power stations of the same scale, but also effectively solve the problem of power loss in boosting and long-distance transportation.

The composition of distributed photovoltaic power generation

The composition of distributed photovoltaic power generation mainly includes:

1. Solar cell modules.The core component of a photovoltaic system is to convert solar energy into electrical energy.
2. Protective devices
3. Circuit
4. Inverter.A device that converts direct current into alternating current.
5. Grid interface

Characteristics of distributed photovoltaic power generation

1. The output power is relatively small. Generally speaking, the capacity of a distributed photovoltaic power generation project is within a few kilowatts.
2. Low pollution, outstanding environmental benefits. Distributed photovoltaic power generation projects have no noise and do not pollute air and water during the power generation process.
3. To some extent, it can alleviate the local electricity shortage situation.
4. It can generate electricity and use electricity simultaneously. Distributed photovoltaic power generation is connected to the distribution network, with electricity consumption coexisting and requiring local consumption as much as possible.

Application of Distributed Photovoltaic Power Generation Projects

1. Industrial applications
   Especially in factories with high electricity consumption and high online electricity purchases, the roof area of the factory is usually large, and the roof is open and flat, suitable for installing photovoltaic arrays;
   At the same time, due to the high electricity load, distributed photovoltaic power generation can achieve on-site consumption, offsetting a portion of online purchased electricity, thereby saving users’ electricity bills.
2. Commercial applications
   The difference between commercial buildings and industrial areas lies in the fact that they mostly have cement roofs, which are more conducive to installing photovoltaic arrays. However, there are often requirements for the aesthetics of the buildings, which are installed according to the characteristics of service industries such as commercial buildings, office buildings, hotels, and conference centers. The user load capacity is generally higher during the day and lower at night, which can better match the characteristics of photovoltaic power generation.
3. Residential applications
   There are a large number of available roofs in residential areas, including self owned residential roofs, vegetable greenhouses, fish ponds, etc. Residential areas are often located at the end of the public power grid, with poor electricity quality. Building distributed photovoltaic systems in residential areas can improve electricity security and quality.
