What are the Basic Parameters of Custom Solar Panels?

Custom Solar Panels have several basic parameters, rated power (Pmax), efficiency (η), open circuit voltage (Voc), short circuit current (Isc), peak voltage (Vmpp), and peak current (Impp).

Custom Solar Panel

Their definitions are as follows:

Rated power (Pmax): indicates the power generated by the maximum power point voltage when the custom solar panel is at the standard ambient temperature (STC, ie, the atmospheric mass is 1.5, ambient temperature is 25 ° C, the light radiation intensity is 1000 W/m 2 );

Efficiency (η): represents the photoelectric conversion efficiency of the silicon wafer inside the custom solar panel, such as an efficiency of 16.5%, which means that the silicon wafer can generate 165 W of electricity per square meter;

Open circuit voltage (Voc): indicates the voltage across the positive and negative terminals (custom solar panel’s no-load voltage) when the solar panel is open at standard ambient temperature;

Short-circuit current (Isc): indicates the short-circuit current generated by short-circuit between the positive and negative terminals of the solar panel when the panel is at the standard ambient temperature;

Peak voltage (Vmpp): indicates the operating voltage of the customized solar panel at the maximum power point (the highest voltage in strong light) when the panel is at the standard ambient temperature;

Peak current (Impp): Indicates the operating current corresponding to the operating voltage of the solar panel at the maximum power point when the panel is at the standard ambient temperature.

After more than two years of accumulation, Longji’s high-efficiency single-crystal modules are distributed in Queensland, New South Wales, Victoria and other places in Australia.

Longji said that the company will continue to strengthen and consolidate its development achievements in the Australian photovoltaic market in the future, and actively help Australian states to promote clean energy such as solar photovoltaic.

6. United States:

The United States, as the world’s third-largest installed market, has an installed potential in the midst of an explosive period.

Benefiting from the impact of ITC’s tax credit policy, in recent years, the U.S. photovoltaic industry has made steady progress. In 2016, U.S. photovoltaic installations surpassed other new energy installations for the first time, reaching 14.762GW. Since the rebound in 2018, new photovoltaic installations in 2019 will It will reach 13GW, and the newly installed photovoltaic capacity will reach 18.5GW in 2020.

As the installed capacity of photovoltaics in the United States increases year by year, the company’s attention to the United States photovoltaic market has continued to increase, and even Tesla has begun to pursue. Not only is Tesla “unrequited” about the US photovoltaic market, domestic photovoltaic companies have already tilted towards this market.

For the fertile soil of the United States, Longji shares are also very favored. In the latest conference call of Longji, Longji revealed that the company’s capacity layout in Malay focuses on the supply to the United States, and the US market shipments will reach about 3GW .

To sum up:

The global photovoltaic industry looks at China, and Chinese photovoltaic companies are in full swing to expand production.

In terms of overseas expansion, in addition to the above-mentioned countries, Longji shares have also been deployed in Pakistan, Malaysia, Norway and other countries. It can be said that it has achieved rapid development and expansion.

Data show that Longji’s five-year compound growth rate of revenue is 57.34%, and its five-year compound growth rate is as high as 104.80%, continuously ranking among the world’s highest photovoltaic companies. At the same time, the output of single crystal silicon wafers ranks first in the world, accounting for about 40% of the global market share, and the number of single crystal module shipments in the world.

In terms of overseas revenue growth, specifically, in 2017, only 10% of Longji’s products were exported overseas; in 2018, module shipments were 7GW, and overseas shipments accounted for 30%. In the first half of 2019, 76% of Longji’s module products were exported overseas, and the sales of single crystal modules reached 2.4GW, exceeding the full-year level of 2018.

At present, the market value of Longji shares has reached 100 billion, and it has become the company with the highest market value in the photovoltaic industry. Coupled with the highest profit halo, it can be called the “king” in the photovoltaic capital market.

It is worth mentioning that Longji shares mentioned in the recently released 2019 performance forecast that the company’s performance in 2019 will achieve a substantial increase and the overseas market will grow significantly. In 2019, Longji’s overseas market business revenue accounted for more than 60%.

Longji is expected to realize a net profit attributable to shareholders of listed companies of 5 billion to 5.3 billion yuan in 2019, an increase of 2.442 billion to 2.742 billion yuan over the same period last year, and an increase of 95.47% to 107.7%. 19%. At the same time, in 2019, the company expects to realize a net profit attributable to shareholders of listed companies after deducting non-recurring gains and losses of 4.817 billion-5.117 billion yuan, a year-on-year increase of 105.50%-118.30%.

Tesla, Jinko Scramble To Lay Out the Roof Photovoltaic, Is the Era of Customization Coming?

With the rise of global green energy, the development of the rooftop photovoltaic market has become a general trend. Whether domestic or overseas, this market is being deployed one after another. 

Earlier this year, Tesla CEO Elon Musk stated that the company will prepare to launch solar roof business in other international markets outside the United States in 2020, including China. 

20W Solar Panel from WSL Solar 

Tesla’s layout of its solar roof business dates back to 2008. 

In October 2008, Tesla founder Elon Musk’s cousins ​​Lyndon Rive and Peter Rive founded SolarCity, a family photovoltaic installation company with a cumulative installed capacity of more than 3GW. It was once the largest domestic solar photovoltaic system service provider in the United States. 

In December 2012, SolarCity went public on the Nasdaq and acquired Silevo in 2014, extending from photovoltaic installation services to the manufacturing of battery modules. 

In June 2016, Tesla purchased SolarCity under its $ 2.6 billion stock, but SolarCity was in a dilemma when it was acquired. In the following years, its business plummeted and it suffered annual losses.Musk was also accused by Tesla shareholders and To sue. 

In October 2019, Tesla launched its third-generation photovoltaic roof product (Solar Roof V3). Due to the use of Chinese photovoltaic cells, the price is 40% lower than in the past. 

In December 2019, Musk stated on Tesla’s earnings call that Tesla’s photovoltaic and energy storage business will grow faster than its electric vehicle business, and Tesla will focus more on Tesla Pull on the energy business. 

According to the company’s latest developments, Tesla is looking for “business and residential user-side” business development managers, project development engineering managers and other related talents. The monthly salary for the position of business development manager is 30,000 to 40,000 yuan, that is, the highest annual salary can be Up to 480,000 yuan. It is enough to see Tesla’s determination to revive the solar roof photovoltaic business. 

In fact, Tesla’s development of photovoltaics in China is inseparable from Chinese products and technologies. In the final analysis, Tesla’s main profit model is to improve Tesla’s new energy electric vehicle charging needs, and use solar photovoltaic power generation as a new investment profit growth point. 

The industry’s analysis of Tesla’s business model found that the company made profits through investment in photovoltaic power plants, so Tesla’s benchmarking company was photovoltaic power plant development investment and operating companies. 

It is unclear whether Tesla’s BIPV business in China will replicate the US model. 

Back in the domestic market, companies’ investment in rooftop photovoltaics is also in full swing. 

Since the fourth quarter of 2019, Jinko has launched its N-type all-black module, which is specifically targeted at the residential roofing market. It has a 405-watt residential version with an efficiency of 21.22%. The launch of this product means that The company will vigorously expand its photovoltaic home roof business in 2020 in Europe, Japan, Australia, Southeast Asia and China. 

On January 4, 2020, Ganneng announced that Jiangxi Yuchen Smart Energy Co., Ltd., a subsidiary of the company, plans to build a 16MWp rooftop photovoltaic power generation project in the Oufei Light Park in the high-tech zone of Nanchang, Jiangxi Province. The total planned investment of the project is about 5,400. It is planned to be connected to the grid for power generation in the first half of 2020. 

On March 4, 2020, Jinlang Technology and Wal-Mart jointly created an urban green photovoltaic roof, aiming to achieve the 2025 emission reduction target and promote the harmonious symbiosis of industry development and the natural environment. 

In fact, from 2013 to 2020, just 7 years after the Chinese household photovoltaic market was subsidized by the government, the Chinese household photovoltaic market set off an ups and downs for the whole nation. 

Since the “531 Policy”, whether for active or passive reasons, in order to promote the further reduction of photovoltaic power generation costs, Chinese photovoltaic companies are getting rid of the risk of a single market and actively deploying the rooftop photovoltaic market. 

According to the industry, the early pain points of rooftop photovoltaic include sub charging, high power with low power, exaggerated publicity, and making quick money in the business process. There is no shortage of short-term speculation in the industry, no long-term planning, and even zero investment in maintenance after installation. What’s more, some brand advertisements promise a 20-year guarantee, but in fact they haven’t done operation and maintenance work and can’t guarantee quality at all. 

As photovoltaic power generation enters millions of households, the competition on rooftop photovoltaics will shift from simply competing for rooftop resources to a high-quality, high-security, high-tech competition model with efficient technology as its core competence. 

In the future, rooftop photovoltaics will enter the era of efficient technology and personalized customization. 

In terms of system design, Chinese companies are also exploring and innovating. They have conducted in-depth research in the areas of rapid assembly, saving materials, and reducing assembly labor costs in order to have multiple advantages. 

In the future, the focus of photovoltaic research and development will also focus on photovoltaic materials to high-efficiency cells, high-efficiency components, and customized system integration design. Think about how to integrate excellent technology and equipment to share the huge “cake” of the rooftop photovoltaic market. “.

China to build space-based solar power station by 2035

China plans to accomplish a 200-tonne megawatt-level space-based solar power station by 2035, according to the China Academy of Space Technology.

The space-based solar power station would capture the sun’s energy that never makes it to the planet, said Wang Li, a CAST research fellow with the program, when attending the sixth China-Russia Engineering Forum held last week in Xiamen, southeast China’s Fujian Province.

The energy is converted to microwaves or lasers and then beamed wirelessly back to the Earth’s surface for human consumption, Wang said.

“We hope to strengthen international cooperation and make scientific and technological breakthroughs so that humankind can achieve the dream of limitless clean energy at an early date,” Wang said.

Custom Solar Panel from WSL Solar

Compared with traditional fossil energy, which has been increasingly exhausted and is responsible for severe environmental issues, space-based solar power is more efficient and sustainable, providing a reliable power supply solution for satellites and disaster-hit areas or isolated areas on the Earth, Wang said.

The concept of collecting solar power in space was popularized by science fiction author Isaac Asimov in 1941. In 1968, Peter Glaser, an American aerospace engineer, wrote a formal proposal for a solar-based system in space.

China has proposed various sunlight collecting solutions and made a number of major breakthroughs in wireless energy transmission since the country listed space-based solar power as a key research program in 2008.

However, ambition has long been a challenge for current technology because it involves the launch and installation of numerous solar panel modules and the efficient wireless transmission of mega energy.

With an investment of 200 million yuan ($28.4 million), China is building a testing base in Bishan, southwest China’s Chongqing Municipality, for the research of high-power wireless energy transmission and its impact on the environment.

Researches in this field will spur the country’s space science and innovation in emerging industries like commercial space transportations, Wang said.

What is AIoT?

AIoT (Artificial Intelligence Internet of Things) = AI (Artificial Intelligence) + IoT (Internet of Things). AIoT integrates AI technology and IoT technology. Through the Internet of Things, massive amounts of data are generated and collected in the cloud and at the edge, and then big data analysis and higher forms of artificial intelligence are used to realize dataization and intelligentization of everything. The Internet of Things technology and artificial intelligence are pursuing an intelligent ecosystem. In addition to the need for continuous innovation in technology, the implementation and application of technology are the core issues in the field of Internet of Things and artificial intelligence that need to be broken at this stage.

Concept of AIoT

From a broad definition, AIoT is the integration of artificial intelligence technology and the Internet of Things in practical applications. It is not a new technology, but a new form of IoT application, which distinguishes it from traditional IoT applications. If the Internet of Things is to interconnect all ordinary objects that can perform independent functions and connect everything with the network, then AIoT will give it more intelligent features based on this, so that everything in the true sense can be interconnected.

On October 16, 2017, Legrand and Nanjing IoT jointly held the Internet of Things and Smart Home Global Summit Forum in Nanjing with the theme “AIoT, Meet a New Future”. The event attracted experts from the fields of artificial intelligence, the Internet of Things, the Internet, and home appliances to discuss in depth the application and impact of related technologies such as AIoT. For the first time, the industry pushed the concept of AIoT to the masses.

On November 28, 2017, at the “Smart Future of All Things · AIoT Future Summit” co-sponsored by Guangji Capital, 36 氪, and Tsinglian, experts and industry guests believed that with the continuous expansion of the Internet of Things application scenarios, the industry The space is gradually expanding, and AI enters the second half of development. When combined with IoT, it will open an important channel for artificial intelligence to really land.

On the same day, at the first Xiaomi IoT Developers Conference, Xiaomi announced that it had reached an in-depth cooperation with Baidu and would cooperate in the field of Internet of Things (IoT) and artificial intelligence (AI). The era of the Internet of Everything and artificial intelligence has arrived, and artificial intelligence and the Internet of Things will form a perfect complementarity and combination. Artificial intelligence will become a new breakthrough point for the further sustainable development of the Internet of Things. It will allow the Internet of Things to enter a new era. .

WSL Solar’s 6V Solar Panel for AIoT

Application Range of AIoT

Whether it is AI or the Internet of Things, one key is indispensable: data.

Data is the foundation of Internet of Everything and human-computer interaction. The involvement of AI gives the IoT a “brain”. Similarly, thanks to the development of current storage technology, data has a basic “logistical guarantee”. The rapid expansion of cloud services has given data a material basis for value.

After the “integration” of AI and IoT, “artificial intelligence” has gradually developed to “application intelligence”. Deep learning requires the sensor collection of the Internet of Things, and the system of the Internet of Things also needs artificial intelligence to correctly identify, find anomalies, and predict the future. From this, it can be seen that artificial intelligence combined with the Internet of Things (AIoT) is the next major development. And this development affects all walks of life, and even subverts the industry. In other words, AIoT services will appear in large numbers next to us.

In the list of the first batch of national new generation artificial intelligence open innovation platforms, relying on Baidu ’s “autonomous driving” national new generation artificial intelligence open innovation platform, relying on Alibaba Cloud ’s “urban brain” national new generation artificial intelligence open innovation platform, relying on Tencent The new generation of artificial intelligence open innovation platform of “Medical Imaging” national construction, and the new generation of artificial intelligence open innovation platform of “Smart Voice” national construction relying on HKUST.

Advantages and Disadvantages of Epoxy Solar Panel

Epoxy Solar Panel is a kind of solar panel, but the encapsulation method is different. The solar cell is cut into small pieces by using a laser cutter to make the required voltage and current, and then encapsulated. Due to the small size, the encapsulation method such as glass laminated or PET laminated solar panel is generally not used, but the solar cell sheet is covered with epoxy resin and bonded with the PCB circuit board.

6V Solar Panel (Epoxy) for Solar Lighting

Application notes

The size of the solar panel can be customized according to the size required by the customer. The working voltage and working current can be customized. Generally, the epoxy solar panel is used to charge the battery of solar charger, solar light, toy and other small solar application electronic products. The working current is measured in the simulated standard light intensity. The standard test conditions are 1000 W/M 2, 25 ° C, and AM 1.5 conditions. The voltage and current emitted will change with the light intensity of the day. In sunny days, the power generated by the solar panel can be calculated in 4 hours.

Product Usage

Epoxy solar panel is an accessory for solar products. It can charge battery or directly connect load. It can be used in solar lawn light, solar floor lamp, solar garden lamp, solar charger, solar street sign, solar road stud, solar traffic sign, solar flashlights, solar toys and other small electrical products. Medium or large-size solar panels are generally encapsulated in a laminate way. Only solar panels with too small size and a power of only a few watts will be made into epoxy solar panels. Because laminated solar panels have a longer life than epoxy solar panel.

Advantages and Disadvantages of Epoxy Solar Panel

The epoxy solar panel has the characteristics of high production speed, pressure and corrosion resistance, beautiful appearance and low cost.

However, its disadvantage is that the lifespan of the epoxy solar panel is shorter than that of laminated solar panels, and usually the lifespan is only about one year. If it is often exposed to the outdoors, the surface of the epoxy solar panel will become whitish and yellow, which affects the appearance. Therefore, if you want a long-life solar panel, you better choose glass laminated solar panels, ETFE or PET laminated solar panels.

What’s the Construction of a Small Custom Solar Panel?

A solar panel is a device that converts solar energy into electrical energy. Since solar panels can be customized flexibly, small custom solar panels have been applied to many off-grid solar applications, such as solar chargers, solar attic fans, and solar LED lights etc.

Usually the solar panels we see are a complete piece of panel, but do you know what the internal structure of the solar panels is?

Small Custom Solar Panel

Here, we mainly introduce the crystal silicon solar panels that are more common on the market as an example.

The structure of crystalline silicon solar panels is usually: tempered glass / EVA / solar cell / EVA / backsheet.

Solar Panel Construction

(1) Tempered glass: Its function is to protect the main body of power generation (such as solar cells). The choice of light transmission is required:

1. The light transmittance must be high (generally 91% or more); 2. Ultra-white tempering treatment.

(2) EVA: Used to bond fixed tempered glass and solar cell. The quality of transparent EVA material directly affects the life of solar panels. EVA exposed to air is prone to aging and yellowing, thus affecting the light transmission of solar panels, so then, affecting the power generation quality of the solar panels. In addition to the quality of the EVA itself, the influence of the lamination process of the custom solar panel manufacturers is also very large. For example, if the EVA adhesiveness is not up to standard, the bonding strength of EVA and tempered glass and backing plate is insufficient, which will cause EVA early aging, thus affects solar panel’s life.

(3) Solar Cell: Solar cells are the core components of solar panels. The main function of solar cell is power generation. 

(4) Back sheet: Its function is sealed, insulated and waterproof. Generally, materials such as TPT and TPE must be resistant to aging. Most solar panel manufacturers are guaranteed for 25 years. Tempered glass and aluminum alloys are generally no problem. The key is whether the back sheet and silica gel can meet the requirements.

 When the solar cell is soldered, the next step is to laminate, according to the following sequence, tempered glass / EVA / solar cell / EVA / back plate, stacked, and then sent to the laminator for vacuuming, and high temperature lamination. EVA is solid at room temperature, but when EVA is exposed to high temperatures, it becomes liquid. Therefore, in the laminator, after the EVA is melted into a liquid state, the solar cell sheet and the tempered glass and the back sheet are glued together.

Just after laminating from the laminator, usually on the four sides of the solar panel, there is some excess EVA overflow, which requires a knife to cut and burr. After processing, a complete solar panel is produced.
