According to the existing photovoltaic power generation projects on the market, combined with different application scenarios, solar photovoltaic power generation systems can be roughly divided into five types: grid-connected power generation systems, off-grid power generation systems, off-grid energy storage systems, and grid-connected energy storage systems and a variety of energy hybrid micro-grid systems.

And off-grid energy storage system

It is composed of photovoltaic modules, solar energy and off-grid integrated machine, battery (energy storage), load, etc. It is widely used in scenarios such as frequent power outages or photovoltaic self-use without surplus electricity, self-use electricity price is more expensive than on-grid electricity price, peak electricity price is more expensive than valley electricity price, etc.

The photovoltaic array converts solar energy into electrical energy under the condition of light, and supplies power to the load through the solar controller inverter integrated machine, and at the same time charges the battery; when there is no light, the battery supplies power to the solar controller inverter integrated machine. Then supply power to the AC load function. Dual mode switching to ensure power supply requirements.

Photovoltaic grid-connected energy storage system

It consists of photovoltaic modules, solar controllers, batteries, grid-connected inverters, current detection devices, loads, etc. It can increase the proportion of spontaneous self-use.

When the solar power is less than the load power, the system is powered by the solar power and the grid together. When the solar power is greater than the load power, the solar power supplies the load while storing the excess electricity through the inverter.

Microgrid system

A power distribution network composed of distributed power sources, loads, energy storage systems and control devices. The distributed energy can be converted into electrical energy on the spot, and then supplied to the local load nearby.

The microgrid system is an autonomous system capable of self-control, protection and management. It can not only be connected to the external power grid, but also can operate in isolation, which greatly solves the problem of distributed power grid connection and promotes the integration of distributed power The large-scale access of renewable energy is an efficient supply of multiple forms of energy for the load, and a smart grid system that realizes the active distribution network.

Secondly, let's talk about the difference between photovoltaic grid-connected and off-grid?

Photovoltaic grid-connected systems rely on the power grid and adopt the working mode of "spontaneous self-use, surplus electricity connected to the grid" or "full grid connection", while off-grid systems do not depend on the grid, relying on "storage while using" or "store first and use later". working mode.

Crystalline silicon photovoltaic modules are an important part of the photovoltaic power generation system. The quality of the modules directly affects the power generation performance of the power station. The main components are tempered glass, EVA, cells, ribbons, backplanes, frames, junction boxes, sealants, etc. Material properties and common appearance defects are as follows:

Learn to understand the composition and structure of photovoltaic modules

1. Cells

Crystalline silicon cells are mainly made of semiconductor silicon. After the light is irradiated on the semiconductor, the P-N junction of the cell receives light (the P-type junction is silicon doped with trivalent boron, the N-type junction is silicon doped with pentavalent phosphorus, the junction of the two is the P-N junction, and silicon is tetravalent Semiconductors) create a potential difference and thus a current flow. At present, the thickness of the cell is 200±20μm, and it is easy to be damaged by force during the production process. The common problems are shown in the figure below:

2. Ribbon

The soldering strips used in multibusbar solar photovoltaic modules are tin-coated copper strips, which are divided into interconnection strips and bus strips. The interconnection strips are used to connect battery sheets, and the bus strips are used to connect battery strings, which play the role of conducting electricity and collecting electricity; common defects at the welding strips include welding There are material problems and welding problems, as shown in the figure below:

4. EVA

EVA is used to encapsulate spliced battery strings, which is a copolymer of ethylene and vinyl acetate. EVA is non-viscosity at room temperature and easy to operate. After certain process conditions, hot pressing will undergo fusion bonding and cross-linking curing, and become completely transparent. The cured EVA can withstand atmospheric changes and is elastic. In addition, after it is bonded to glass, it can increase the light transmittance of the glass, play the role of anti-reflection, and have a gain effect on the output of solar cell components. Common problems can be divided into material reasons and process reasons, as shown in the following figure:

5. Backplane

At present, the commonly used backplane structures include TPT, TPE, TPF, KPK, KPF, etc., which are used as packaging materials on the back of the module. It reflects sunlight, so the efficiency of the module is slightly improved, and because of its high infrared emissivity, it can also reduce the operating temperature of the module, which is also conducive to improving the efficiency of the module. It also needs to have properties such as aging resistance, corrosion resistance, water vapor penetration resistance, and insulation. Common problems can be divided into backplane material, process, and external force reasons, as shown in the following figure:

6. Border

The frame used by the PERC photovoltaic module is aluminum profile, and the surface of the aluminum profile is anodized, which has the properties of insulation and corrosion resistance, protects the component, increases the load-bearing capacity, and is convenient for transportation and installation. Common problems can be divided into material reasons and external force reasons, as shown in the figure below:

7. Junction box

The junction box used by photovoltaic modules is composed of a box cover, a box body, a pole tube, a connecting wire, and a connector; the sealing method usually includes potting glue sealing and sealing ring sealing, and its main functions are as follows:

(1) Connect the lead wire of the component to derive the current generated by the component.

(2) Protection: heat dissipation, prevent hot spot effect, seal anti-aging.

The common problems of junction boxes are mainly due to material and process reasons, as shown in the following figure:

8. Sealant

Photovoltaic modules are currently mainly sealed with silica gel or adhesive tape, which must have the characteristics of waterproof, UV resistance, and weather resistance, as shown in the figure below:

Technology development trend of photovoltaic cells - P to N is imperative.

Photovoltaic solar cells technology iterations continue to focus on "efficiency enhancement" + "cost reduction" At present, the average mass production efficiency of PERC cells is 23.2%, and the theoretical conversion efficiency limit is 24.5%. The mass production efficiency has already approached the theoretical limit of efficiency, making it difficult to increase the efficiency of PERC cells significantly. N-type solar cells technology iteration is imperative.

Compared with traditional P-type solar cells, N-type solar cells have the advantages of high conversion efficiency, high bifaciality, low temperature coefficient, almost no light decay, and good weak light effect. Currently, mainstream N-type solar cells include TOPCon, HJT, IBC, etc. TOPCon has high limit efficiency and low cost of production line transformation; HJT has high mass production efficiency and a clear cost reduction route; IBC conversion upper limit is higher, but economical improvement still takes time. At present, the actual mass production yield rate of Topon is 24%-25.2%, and the actual mass production efficiency of HJT is about 25%, which is 1%-2% higher than that of P-type PERC cells.

 

   The first generation of cells—silicon-based solar cells: the battle between monocrystalline and polycrystalline mainstreams

    In 1839, French scientist A.E. Becquerel discovered the photovoltaic effect. When two pieces of platinum metal were clicked and inserted into an acidic solution, an electric current flowed between the electrodes, opening the door to the world of photovoltaics. By 1954, the United States produced the first monocrystalline silicon solar cell, marking the birth of photovoltaic power generation technology.

    P-type and N-type iterations, leading XBC solar cell

   In recent years, as the conversion efficiency of P-type solar cell has gradually approached the "ceiling", it has become a general trend to iterate from P-type to N-type technology. As far as the first half of 2023 is concerned, about 19.55% of N-type solar module projects have been targeted, and N-type shipments and production capacity of various photovoltaic companies have increased to varying degrees.

    According to the latest module efficiency published on the report, the top-ranked modules are basically N-type solar panels.

    On September 5th, 2023, LONGi announced its bet on XBC solar cells. TOPCON and HJT use new passivation contact structures to improve the passivation effect and thereby increase conversion efficiency. The front of XBC solar cells is not blocked by metal grid lines, eliminating the front metal electrode structure. , able to maximize the utilization of incident light.

    Compared with HIT solar cells and XBC solar cells, TOPCON solar cells have better compatibility with P-type solar cells production lines and lower transformation costs. The transformation investment per GW is about 50-70 million, making it main layout object in the current N-type solar cell production capacity of photovoltaic companies .

France has submitted an updated National Energy and Climate Plan (NECP), raising its solar photovoltaic installed capacity target to 60GW in 2030.

 

 

Compared with the previous NECP submitted in 2019, the new draft adds at least 14GW of installed photovoltaic capacity. By 2035, France aims to increase its cumulative photovoltaic installed capacity to 75-100GW.

 

Although this increase may not be high compared with neighboring countries such as Spain and Italy. These two countries aim to have PV installed capacity of 76GW and 80GW respectively by 2030, especially Spain, which plans to nearly double its previous solar PV target.

 

Nuclear power appears to remain an important part of France's electricity decarbonization goals, as the draft NECP shows that the word "nuclear power" is mentioned 104 times and "solar" 19 times, many of which are related to solar heat. Last year, nuclear power accounted for 62.2% of France's electricity generation, wind power accounted for 8.7%, and solar power accounted for only 4.2%.

 

As of the end of 2022, France's photovoltaic installed capacity was 15.7GW, of which 2.6GW was added last year, accounting for more than half of the total newly installed renewable energy capacity in 2022 (more than 5GW).

 

Other updated targets include France’s plan to add 5.5-7GW of new photovoltaic capacity per year. Most of the new capacity is expected to come from large-scale ground-mounted PV, accounting for 65%, rooftop commercial and industrial will account for 25%, and the remaining 10% will be household solar.
