Who Is More Likely to Share the Big Cake of BIPV?

Recently, it has been reported that the new BIPV products that Longi New Energy is about to release will be officially launched on the market in the second half of this year after more than a year of research and development and preparation.

It is understood that in order to effectively solve the shortcomings of the short service life of the existing industrial and commercial buildings, the weak waterproof and wind resistance, and the long-term idle roof, etc., Longji BIPV new products will comprehensively improve the performance and service life of BIPV products such as thermal insulation, windproof and waterproof, fire and lightning protection, impact resistance, light weight, etc., while achieving the perfect combination of efficient power generation and reliable building materials.

Longji announced in 2019 to enter the BIPV market, and will launch its own industrial and commercial BIPV roof products in mid-2020, and plan to achieve BIPV revenue volume of 10 billion yuan by 2024.

It is understood that as of now, Longji IPV production line equipment has been installed and commissioned, and will soon enter the mass production stage. The official product name and time to market of the new Longi BIPV products have also been finalized and will be officially announced in the second half of this year.

Tesla in the North American market has a soft spot

In fact, after years of development in BIPV, the industry has moved from concept to implementation.

More and more companies realize that the integration of solar photovoltaic modules and building materials is a double benefit for the solar photovoltaic industry and the construction industry, and in the process has set off a new revolution in green development.

In terms of application form, BIPV is a new hotspot of distributed photovoltaics. Compared with BAPV with a single application scenario, BIPV can be applied to roofs, curtain walls, sunshades, greenhouses, etc.

Based on this, BIPV can be applied to a series of scenarios such as photovoltaic tile surface, daylighting roof, external window shading, awning and so on.

Overseas, there has also been new progress in BIPV’s R&D and business development. Judging from the trends of foreign companies, Tesla can be described as having a soft spot for the BIPV business.

Tesla’s solar rooftop business can be traced back to 2008 at the earliest. After continuous innovation of technology, in October 2019, Tesla launched the third generation BIPV residential roof system Solar Roof V3, with a cost of about $34,000 per set. According to the California average electricity price, Tesla’s solar roof V3 standard project The payback period is 11 years.

The third generation of Solar Roof mass-produced photovoltaic roof products for the first time. This product embeds photovoltaic cells in tempered glass to realize the integration of photovoltaic buildings.

In March 2020, according to the company’s latest developments, Tesla is looking for “commercial and residential user side” business development managers, project development engineering managers and other relevant personnel. The monthly salary for the business development manager is 30,000 to 40,000 yuan. That is, the annual salary can be up to 480,000 yuan. It is enough to see Tesla’s determination to revive the solar rooftop photovoltaic business.

Recently, Tesla China has newly added three recruitment information for the solar roof business. Combined with the previous two recruitment information in March, it is not difficult to find that Tesla’s BIPV business has officially opened in the Chinese market.

Relevant agencies pointed out that this year, affected by the epidemic situation at home and abroad, the price of the industrial chain has fallen sharply, and the cost side continues to fall sharply. It is expected that the scale of the bidding index this year is expected to exceed expectations, while the consumption expansion will also facilitate the promotion of parity projects. According to estimates, the annual installation of Tesla photovoltaic roofs in the North American market is expected to reach 5-10GW per year.

Domestic photovoltaic companies “distribute huge cakes”

BIPV has amazing market development potential, with a potential market space of hundreds of billions. This provides BIPV with sufficient business bearing and development space.

According to the National Bureau of Statistics data and the China Academy of Building Research estimates, China’s existing building area is about 80 billion square meters, solar photovoltaic cells can be installed nearly 3 billion square meters, and the installed capacity is about 400GW; at the same time, China’s new construction area is about 40 100 million square meters, about 300 million square meters of solar cells can be installed, and the installed capacity is not small.

This huge cake has made many domestic photovoltaic companies “coveted”.

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

In the domestic market, in addition to Longji shares, CITIC Bo, Dongfang Risheng, Jinko are also early BIPV companies.

As one of the earliest domestic enterprises engaged in photovoltaic power generation business, Dongfang Risheng is also actively deploying BIPV. At the beginning of 2020, Dongfang Risheng said that the company has reserved and applied BIPV-related technologies.

It is understood that Dongfang Risheng Changzhou’s 2.05MW BIPV project has passed the grid acceptance on August 28, 2019 and started generating electricity. It is estimated that the average annual power generation is about 2 million kWh, and the internal rate of return on investment is 14.8%.

CITIC Bo predicts that in the future, more owners will adopt BIPV integrated solutions. While enjoying the green benefits of solar power generation, they will also save the capital cost and time of roof repairs.

JinkoSolar provides predictions of the legislative requirements for photovoltaic buildings. Jinko Electric stated that by 2025, more and more countries and regions will adopt local regulations to modify or add new building standards for local application of solar energy systems. It is required that within a certain height, new residential buildings above a certain area must be installed with photovoltaic systems; all suitable industrial and commercial roofs of the park must be installed with photovoltaics, which will also be incorporated into local park management regulations.

The new BIPV products to be released by the above Longji New Energy will comprehensively apply leading technologies such as double-glass half-sheet high-efficiency single crystal, 360-degree upright locking, seamless splicing, etc. At the same time of performance and service life, it realizes the integration of efficient power generation and reliable building materials.

When visiting the production line of Longji Stock, Three Gorges Capital said: “Longji has launched a landmark BIPV product, hoping to continue to lead the new direction and trend of the development of the photovoltaic industry. BIPV, as the future development direction of green buildings, deeply integrates building materials and photovoltaic energy The functions and characteristics of the company will continue to promote the diversified development of clean energy.”

According to the Longji BIPV building photovoltaic integrated solution, the project investment recovery period is only 7-8 years, and the IRR (internal rate of return) reaches 11%.

The good news is that, according to the policy of the National Energy Administration, the wind power consumption space is 37GW, and the photovoltaic power consumption space is 48GW, which greatly exceeds the market’s expected consumption indicators of 30GW for wind power and 40GW for photovoltaic. At present, all provinces have started the declaration work for photovoltaic parity and bidding projects in 2020, and they will land before the end of June. The expansion of the consumption index will undoubtedly give the applicants confidence.

Regarding the future prospects of BIPV, industry insiders believe that BIPV is a key technical factor to solve the demand for near-zero energy consumption of building electricity. With the rapid reduction of the cost of the photovoltaic industry chain in recent years, the photovoltaic industry has moved from photovoltaic power plants to BIPV. Relying on the era of no subsidies, the rise of spontaneous market demand will open up a broad space for the development of BIPV.

Poland’s Solar Photovoltaic Market Explodes, and Traditional Coal Industry is Under Threat

Recently, the unions of PGG, Poland ’s largest coal group, warned that if the government does not provide help, the coal industry will collapse due to falling demand. Poland relies heavily on coal-fired power generation and is the only EU member state that has not committed to zero carbon emissions by 2050. But in the face of increasing pressure from the EU to reduce emissions, Poland began to encourage investment in solar and offshore wind farms. The increase in the share of clean energy in power generation, the decline in power demand after the epidemic is closed to the city, and coal imports have exacerbated problems in the coal industry.

Custom Solar Panel | 6V 3W – WSL Solar

The Polish government previously stated that the installed capacity of solar photovoltaics will reach 10.2GW in 2030 and 20.2GW in 2040. The Polish government also supports industrial and commercial and large-scale power plant projects through the renewable energy auction system. The new government regulations allow owners of solar photovoltaic systems of more than 50 kW to sell excess power. Growth in the industrial and commercial field will be particularly strong. At the same time, the promotion of rooftop solar photovoltaic incentives and corporate net measurement policies has stimulated the potential of the solar photovoltaic market. In 2019, solar power generation in Poland has risen sharply.

On the other hand, due to the increase in the price of carbon dioxide certificates, the impact of the increase in the price of European carbon dioxide emission quotas will seriously affect Poland ’s electricity prices, and coal is the most intensive energy source for carbon dioxide. Great power to promote the development of clean energy in Poland.

According to SolarPower Europe data, in 2019 Poland ranked fifth in the number of new photovoltaic installations among European countries, and it is only 300MW less than the fourth place in France. It is also unknown that it exceeds France. In early 2020, Bloomberg predicted that Poland will be one of the top ten global solar photovoltaic markets this year.

210 Technology Replacement Demand Exceeds 20 Billion, HIT Leads the New Trend of Next-generation Photovoltaic Cells

In the face of the epidemic sweeping the world, the problem of “two-level differentiation” is in front of the photovoltaic people.

SMEs are struggling in a crisis-ridden environment and seeking hope for life, but for leading companies, it is still difficult to stop their pace of active expansion.

The leading domestic solar cell manufacturers are not afraid of the impact of the epidemic and are actively expanding production.

Custom Solar Panel for Solar Powered LED Lighting

Recently, Tongwei issued a fixed increase plan, which will raise no more than 6 billion yuan of funds, and it is expected that 4.2 billion will be invested in Meishan Phase II (7.5GW) and Jintang Phase I (7.5GW) high-efficiency solar cell projects.

In addition to Tongwei, LONGi has announced a total expansion of 10GW of monocrystalline solar cells, AiXu expanded by 5.9GW, Jingao expanded by 10GW, and Jinko expanded by 10GW. It is expected that PERC solar cell expansion will reach 30GW this year , The corresponding equipment amount is more than 6 billion, and it is expected to begin to place orders in Q2.

It is worth mentioning that the acceleration of the industrialization of 210 silicon wafers is still the main theme in 2020.

Judging from the announcement issued by Tongwei this year, the above projects are mainly based on the 210-size PERC technology route, and reserve space for PERC + / TOPCON equipment.

From the perspective of this year’s new expansion plan for solar cells, the expansion of solar cell factories led by Tongwei and Aixu are mainly based on 210 large sizes.

Among them, the first 210 solar cell workshop of Tongwei-Meishan Phase I is expected to be mass-produced in mid-May, and the follow-up Meishan Phase II and Jintang 30GW plans will take the 210 route.

In January, Axu announced the mass production of 5GW 210 solar cell production line. It also plans to expand its solar cell capacity to 22GW by the end of 2020, 32GW by the end of 2021, and 45GW by the end of 2022.

As for solar modules, Dongfang Risheng and Trina Solar have successively released 210mm 500W solar modules.

In addition, as the leader of 210 large silicon wafers, China Central also recently announced an investment of 5 billion yuan in the construction of G12 PERC + solar cell lines and shingled solar module projects, which will further promote the industrialization of large-scale silicon wafers.

Relevant institutions judge that the future increase in the penetration rate of 210 technology will exceed market expectations. It is expected that the industry replacement demand brought by large silicon wafers will exceed 20 billion, and Jingsheng Electromechanical as the only supplier of 210 single crystal furnaces will greatly benefit.

It is worth noting that as early as a few years ago, in the photovoltaic industry, there have been disputes between PERC, TOPCON and HIT technologies in the solar cell technology.

It is reported that PERC + is based on P-type silicon wafers and currently has a laboratory efficiency of 23.5% or more. It is necessary to superimpose 4 devices on the original PERC production line. It is expected that a prototype will be released by the end of 2020 and need to be verified by the production line.

TOPCON is based on N-type silicon wafers, with a conversion efficiency of over 23.5%. The equipment is relatively mature, but since N-type silicon wafers and equipment are relatively expensive, the overall cost is higher than PERC +.

The industry believes that the current conversion efficiency of PERC + / TOPCON can reach more than 23.5%, but the cost reduction route is still unclear. It needs to undergo production line inspection and is expected to become a transition path for PERC to upgrade to the next generation of technology.

In terms of HIT, it can be said that the progress has been quite effective. Taking Tongwei as an example, the average conversion efficiency of its multi-main grid starts at 23.5%, and it is expected to see more than 24% in the second half of the year, and the highest efficiency on the production line is close to 25%. But at present, it is still not comparable to PERC in terms of cost performance.

In 2019, in addition to the four HIT test projects of Tongwei and Shanmei International, battery factories such as Aikang and Artus have also successively launched HIT layouts since 2020.

The industry predicts that with the decline of HIT costs and the improvement of conversion efficiency in the next two years, HIT will become a megatrend for the next generation of photovoltaic solar cells.

The Total Market Value Exceeded 100 Billion Yuan! “Expansion King” Longji’s Q1 Net Profit is Expected to Increase by More Than 170%

In the first quarter of 2020, solar photovoltaic companies issued performance forecasts, and more than half of the companies were affected by the epidemic, resulting in a decline in net profit.

However, the epidemic did not affect Longji, the world’s largest manufacturer of monocrystalline solar products.

On the evening of April 16, Longji announced that it expects to realize net profit attributable to shareholders of listed companies in the first quarter of this year of 1.65 billion to 1.950 billion yuan, an increase of 175.05% to 219.15% year-on-year. After deducting non-recurring gains and losses, the company’s net profit also reached 1.549 billion yuan to 1.849 billion yuan.

Public information shows that in the same period last year, Longji shares realized a net profit attributable to shareholders of listed companies of 611 million yuan. As a result, in the first quarter of 2020, Longji’s main business performance was very strong.

“The King of Expansion” Expanding Production Capacity

According to the announcement, Longji shares attributed the rapid growth of performance to the expansion of production capacity.

Throughout the entire solar photovoltaic industry, Longji shares are well-deserved “kings of expansion,” and public data compilation shows that the investment amount of Longji shares reached as high as 30 billion yuan in 2019 alone.

Longji said that under the influence of the expansion of production capacity, the company’s main products monocrystalline solar wafers and solar modules sales increased rapidly year-on-year, the proportion of large-size silicon wafers and high-power solar module products increased rapidly, and the operating income increased significantly year-on-year Costs continued to decrease, and product gross profit margins increased year-on-year.

Looking back on 2019, in the case of sluggish domestic PV market demand, many domestic PV companies, including Longji, have chosen to “go overseas.” Taking the company’s solar module shipments in the first half of 2019 as an example, its overseas shipments accounted for 70%.

Longji said that in the first quarter of this year, in the face of the spread of the epidemic and the complex external operating environment, it flexibly adjusted its production and operation plans. For overseas orders, the company strengthened timely communication with domestic and foreign customers, and strived to ensure timely and high-quality delivery of orders in hand.

In addition, the crazy expansion of Longji’s shares on the silicon side in 2019 seems to be preparing for the future price war of monocrystalline solar wafers.

On March 25, 2020, LONGi released the price announcement of monocrystalline solar wafers. The price of monocrystalline solar wafers P-type M6 180μm thickness (166 / 223mm) is 3.41 yuan / sheet, which is the price announced on February 24 Compared with it, it is reduced by 0.06 yuan / piece; the price of single crystal solar silicon P-type M2 180 μm thickness is 3.07 yuan / piece. Compared with the price released on February 24, it remains unchanged.

In this announcement, Longji announced the same price for P-type boron-doped and gallium-doped silicon wafers. Industry insiders believe that its official announcement of the same price for both may be laying the foundation for the elimination of backward monocrystalline solar capacity.

The long-term trend of solar photovoltaics has not changed

At present, under the spread of overseas epidemics, short-term demand in overseas markets has been impacted, and whether the overseas sales of Longji shares have been affected has attracted considerable attention from investors.

On April 15th, Longji’s board secretary responded that the epidemic was a short-term impact on the solar photovoltaic industry, and the mid-to-long term trend of the solar photovoltaic industry has not changed. The company’s order fulfillment has been normal in the past week, and it will carefully evaluate the market situation to fully prevent market risks.

It is worth mentioning that in 2020, Longji shares non-stop, and has successively announced a number of expansion projects to further enhance the overall production capacity.

According to public information, Longji’s planned production capacity has exceeded 133GW, and on its traditional strength silicon side, it will achieve 80GW of production capacity in 2020.

It is worth noting that the development trend of large-size silicon wafers has also become a hot topic this year. M6 (166mm) size silicon wafers represented by Longji shares and M12 (210mm) size silicon wafers represented by Zhonghuan shares Direct collision.

According to Longji shares, the company ’s M6 (166mm) silicon wafer orders have been filled in the second quarter since full production resumed in March. Looking forward to the whole year, its calculated M6 silicon wafer will account for more than 70% of the total shipments.

It can be said that from the comparison of production capacity, Longji currently has no rivals on the silicon side.

Finally, back to the performance forecast, affected by the large pre-increased performance of Longji shares, Longji shares opened higher and higher today, and once touched the daily price limit, the total market value exceeded 100 billion yuan.

Relevant agencies expect that the second quarter of this year will be a period of downturn overseas. The adjustment of the industrial chain price will accelerate, driving the demand after the epidemic. The leading share will further increase. The current adjustment is relatively large. The long-term value of the solar photovoltaic leading including Longji shares appears.

Longi: 2020 is the Best Time for BIPV to Take Off

After years of development, BIPV is moving from concept to landing. 

More and more companies realize that the integration of solar photovoltaic modules and building materials is a double benefit for the solar photovoltaic industry and the construction industry, and in the process has set off a new revolution in green development. 

At present, the integration of green intelligent power generation systems in buildings has become the consensus of all countries and the trend of building development. 

BIPV is already well-equipped in China and will usher in rapid development. It is reported that in June 2020, a BIPV project with an installed capacity of up to 40.9 MW in Jiangxi Province will be completed and will be the largest BIPV project in the world after completion. 

BIPV exceeds the “trillion” market development potential, so that many solar photovoltaic companies are “coveted”.

Custom Solar Panel from WSL Solar

Longji announced that in the second half of 2020, the company will join the BIPV market army and is expected to launch new BIPV products and solutions, which will further promote the rapid development of the domestic BIPV market. 

Longji New Energy said that for the Chinese BIPV industry, the industrial and commercial roof market has a huge capacity. According to data statistics, the total area of ​​photovoltaics that can be installed on the roofs of existing industrial and commercial (including public buildings) nationwide is about 6 billion square meters, and the facade is about 1.6 billion square meters, totaling nearly 8 billion square meters. If all are built into BIPV, a total of 1100GW can be installed, equivalent to A potential market of 5.5 trillion yuan. 

As early as two years ago, CITIC Bo discovered the huge business opportunities in the BIPV market. Relying on its own technical advantages, it carried out the preliminary layout, compared the advantages and disadvantages of various types of BIPV projects at home and abroad, and carried out technical research on the core difficulties. 

CITIC Bo predicts that in the future, more owners will adopt BIPV integrated solutions. While enjoying the green benefits of solar power generation, they will also save the capital cost and time of roof repairs. 

As one of the earliest domestic enterprises engaged in solar photovoltaic power generation business, Dongfang Risheng is also actively deploying BIPV. At the beginning of 2020, Dongfang Risheng said that the company has reserved and applied BIPV-related technologies. 

It is understood that Dongfang Risheng Changzhou’s 2.05MW BIPV project has passed the grid acceptance on August 28, 2019 and started generating electricity. It is estimated that the average annual power generation is about 2 million kWh, and the internal investment return rate is 14.8%. 

JinkoSolar has given a forecast of the legislative requirements for photovoltaic buildings. Jinkoko Electric said that by 2025, more and more countries and regions will adopt local regulations to modify or add building standards for local application of solar energy systems. It is required that within a certain height, new residential buildings above a certain area must be installed with photovoltaic systems; all suitable industrial and commercial roofs of the park must be installed with photovoltaics, which will also be incorporated into local park management regulations. 

The industry believes that BIPV is a key technical factor to solve the demand for near-zero energy consumption of building electricity. With the rapid reduction in the cost of the solar photovoltaic industry chain in recent years, the photovoltaic industry has moved from solar photovoltaic power plants to BIPV, and the industry has moved from policy dependence to no In the era of subsidies, the rise of spontaneous market demand will open up a broad space for the development of BIPV.

Longji said that 2020 is the starting point of the rise of BIPV, and BIPV’s investment income can recover the investment in the construction of the entire house within 20-25 years. 

LONGi shares revealed that in China, LONGi’s involvement in BIPV is mainly to enlarge the company’s industrial park, logistics and other major customers, and will not be pushed out to residents for the time being. 

Longji shares once said in a conference call, “Now Longji has done a lot of IP layout, more is the intellectual property protection of appearance and structure, that is, customer recognition, this should be the new blue ocean. In addition, in the photovoltaic scenario such as Rural distributed energy storage plus diesel backup can reduce costs, which is why the company is involved in BIPV (photovoltaic building materials). ” 

Lungi believes that with the continuous decline of BIPV investment costs, the continuous improvement of industry standards and the continuous completion of certification qualifications, market growth is expected to accelerate. Now, perhaps the best time for BIPV to take off.
