LONGi Solar, a leading manufacturer of monocrystalline high-performance modules, has signed a Memorandum of Intent (MOI) with the Tunisian project developer SHAMS Technology for a long-term cooperation.

LONGi Solar and SHAMS Technology will develop PV projects in African markets where SHAMS has an active partner network. As a first step, the two companies are planning a 10 MW project in Kasserine located in the west-central part of Tunisia.

Africa to become third-largest PV market in the future

“In many regions of Africa, the electricity infrastructure is still underdeveloped. We see great potential: Instead of fossil energy, African countries are focusing on generation from renewable sources”, says Richard For, Vice President of LONGi Solar. “In addition, the continent has sufficient solar radiation and enough space for the installation of large photovoltaic systems. We expect Africa to become the world’s third largest market for PV systems in the medium term.”

“We are very proud of the partnership with LONGi Solar. Thanks to the cooper-ation, we can offer customers very high-quality solar modules and services from one of the world market leaders for highly efficient monocrystalline solar cells and modules”, states Mejdi Kilani, CEO of SHAMS Technology. The company already has a partner network of local installers in important African markets, which simplifies the commissioning of contracts for projects and makes local implementation considerably easier.

Ambitious expansion targets for Tunisia

The first joint project with an output of 10 MW is planned in Tunisia, where LONGi Solar and SHAMS will offer high-efficiency monocrystalline photovoltaic modules under the “SHAMS-LONGi” brand. The country has set itself the target of installing a total of 200 MW of photovoltaic capacity by 2022. LONGi and SHAMS have the ambition to supply and install half of this capacity.

Focus on highly efficient mono modules

LONGi Solar is the only manufacturer in the world to specialize completely in monocrystalline high-performance modules. In the first half of 2018, the com-pany invested $105 million in research and development, aiming to reduce electricity production costs, equivalent to 7.18 percent of the company’s reve-nue. No other module manufacturer in the world invests more heavily in technology development.

JL1China-based PV module materials and N-type mono module manufacturer Jolywood (Taizhou) Solar Technology Co is supplying Haixing New Energy, a subsidiary of the Chinese State Power Investment Corporation Limited (SPIC) with high-efficiency modules totalling 64.6MW for a National Photovoltaic Leader Project.

Jolywood said the successful bid included 310W-p N-type monocrystalline bifacial high-efficiency solar modules worth about RMB 171.30 million (US$25.16 million approx.)

In addition to the orders from Haixing, Jolywood said it was also manufacturing 100MW of modules for SPIC's Sihong projects, having won bids earlier in the year.

In May, 2018 Jolywood signed a long-term supply deal with SPIC totalling 5GW, which included supplying 1GW of N-type TOPCon bifacial modules in 2019 and 2GW to be delivered in 2021.

Jolywood has recently partnered imec to bring to market an industrialized bifacial solar cells with an average front-side conversion efficiency up to 21.9%.

Jolywood has significantly increased its cell and module R&D activities since moving into the market. According to PV Tech’s annual R&D analysis report, Jollywood spent US$6.6 million on all R&D activities in 2016, increasing to US$19.23 million in 2017.

Jolywood (Suzhou) Sunwatt Co., (Jolywood) has introduced several new innovations into its N-type monocrystalline bifacial modules that boost cell and module efficiencies, improve durability while lowering balance of material (BOM) cost and overall levelized cost of electricity (LCOE).

Jolywood has forged a partnership with HuangHe HydroPower Development Co.,Ltd, a subsidiary of SPIC, to develop products for the new energy market in China and overseas to promote the rapid application of high-efficiency and the high-reliability of bifacial module technology for the rapid realization of PV grid parity.

The mass production efficiency of the N-PERT solar cells used in Jolywood's cooperation project with SPIC has reached 21.7%, while that of the new TOPCON solar cell is up by 0.9% compared with N-PERT. By the end of 2018, further increases are expected in the range of 0.4% to 23%, respectively. The N-type bifacial technology is said to increase overall power generation by more than 17% compared to P-type single-sided technology. Its N-type bifacial glass-transparent backsheet module enjoys a front power of up to 400W, and its maximum comprehensive power of 480W. The module uses a transparent TPT backsheet developed with DuPont. Jolywood has upgraded the transparent backsheet for high-reflection.

Utility-scale PV power plants.

Compared with traditional backsheet products, the new transparent backsheet boasts multiple advantages such as light weight, breathability, and high gain. In this regard, the transparent backsheet reduces the weight of the module by 30% compared to the double glass structure, thereby decreasing transportation and installation costs; the average transmission rate of visible-near infrared light area is no less than 90%.

Various product introductions from May 2018 onwards.

4 09longiLONGi Green Energy Technology, the world’s largest dedicated manufacturer of monocrystalline wafers and its subsidiary, LONGi Solar, a member of the ‘Silicon Module Super League’ (SMSL) has reported first half year results that included record quarterly shipments, operating income and R&D spending.

LONGi Group reported first half 2018 operating income of approximately RMB 10.02 billion (US$1.49 billion approx.), compared to US$995.2 million approx.), in the prior year period, an increase of 59.36%.

On a quarterly basis, LONGi reported second quarter operating income of US$956.1 million, compared to approximately US$569.1 million in second quarter of 2017, a 68% increase year-on-year.

4 09longi1

The second quarter income exceeded LONGi’s previous quarterly record set in the fourth quarter of 2017, when the company reported an operating income of approximately US$874.8 million.

Although the company mirrored many competitors in reporting relatively soft first quarter results, sue to seasonality in key markets, including China, LONGi’s significant increase in shipments of mono wafers and mono PV modules were behind the operating income growth.

The company reported first half year 2018 mono c-Si wafer production of 1.544 billion pieces, with 758 million pieces old externally and 786 million pieces were used in-house, compared to the first half of 2017 when external sales volume was 449 million pieces, and in-house consumption was 419 million pieces

In the first half of 2018, PV module shipments reached 3,232MW, including sales of 2,637MW and 375MW of modules use for its downstream PV project business, which included a number of poverty alleviation projects in China.

However, the major change in module shipments came from international sales, which accounted for 687MW in the first half of 2018, 18 times higher than the prior year period.

4 09longi2

Less spectacular than the operating income growth was the net profit in the first half of 2018, which reached RMB 1.307 billion (US$190.98 million approx.), a year-on-year increase of 5.73%. The company reported a gross profit margin of 22.62%. However, LONGi remains one of the most profitable PV manufacturers.

The squeeze on profit and margins were mainly attributable to average selling price (ASP) declines, initiated by trade tariffs and the late impact of the Chinese Governments ‘531 New Deal’.

PV Tech had previously reported that LONGi surpassed long-term R&D spending leaders First Solar and Sunpower for the first time in 2017, having allocated over US$175 million to a range of R&D activities at the ingot/wafer level through to cell and modules, which set a new R&D spending record.

In the first half of 2018, LONGi reported R&D spending in the reporting period to have reached approximately US$105 million, a year-on-year increase of 61.80% and accounting for 7.18% of operating income in the reporting period, a new industry record.

To put this in perspective, First Solar’s 2017 annual R&D spending totalled US$88.6 million and Sunpower spent US$80.7 million.

Manufacturers are getting more excited about solar panels that generate electricity on both sides.

Bifacial solar PV technology has long been a novelty.

But pilots announced this summer — including a new Soltec bifacial tracker test center in California, plus a partnership between Array Technologies and a national lab in New Mexico — suggest bifacial is edging toward the mainstream. But manufacturers still need to dial back costs.

Array Manufacturing Plant 11 copy XL 721 420 80 s c1

Before bifacial modules are ready for widespread adoption, manufacturers say the industry has a year or two of data collection to determine how they compete in both efficiency and cost, and what applications they're most effective for.

“Once everyone understands the costs and the implications and can understand the problems, well, the problems get simplified,” said Array founder Ron Corio. “We’re in that simplification process right now.”

The company recently installed two rows of bifacial modules — from manufacturers Longi, JA Solar, Trina, Jolywood, Hanwha Q Cells and Canadian Solar — at a New Mexico national laboratory to test the modules with its trackers and create simulation models from the test rows.
Because bifacial modules collect sun from both the top and the bottom of the panel, they present unique challenges in siting and installation.

“That’s the thing about bifacial,” said Corio. “It’s a big bucket of variables.”

At its new installation site, Array is testing variables like how mounting offsets impact irradiance. In bifacial installations, developers must consider factors including ground albedo, ground cover, irradiance and system design, like trackers, to maximize output.

Those variables add up to one of the technology’s greatest challenges: quantifying power output.

“People understand the variables that make a difference, but they don’t understand how to calculate the actual difference based on those variables,” said Tyler Stewart, vice president of sales and business development at bifacial module company Prism. “If you don’t understand what the backside performance is on the module, then the height, the tilt, or whether it’s on green grass or white snow is kind of a moot point. If your back only produces half as much power as the next [product], and you don’t know that difference, it’s hard to calculate how it’ll actually perform.”

“I think truly the biggest hurdle to that is there’s not a standard,” he added.
Stewart thinks that the next couple of years will change that. The International Electrotechnical Commission, along with testing agencies such as the National Renewable Energy Laboratory and Sandia National Laboratories, has been working on a uniform standard and released a proposed measurement standard. Stewart expects it to be finalized soon.

For now Prism tests the front and back of its modules separately against a black backsheet. Testing against a white sheet can inflate the standard test conditions rating, according to Stewart.

Though the standard hasn’t yet been finalized, Dr. Hongbin Fang, director of technical marketing at Longi Solar, said a module’s backside production can increase energy yield by 15 percent* and possibly more, depending on location and how a bifacial module is installed.

That’s drawn attention from large manufacturers, as well as smaller companies like Prism.
Longi contributed 20 megawatts to a 71-megawatt bifacial project in China — which the firm describes as the world’s largest bifacial solar project — connected in January. And Fang said demand is growing.

“Right now, I think bifacial is a very small portion of...the product mix in the overall industry,” said Fang. “Probably in the next one or two years, once you have this bankability established, the backside gain on the bifacial system established in the market, we believe most of the customers will switch to bifacial.”

While Prism has a several-year pipeline of several hundred megawatts, Longi said it shipped about 100 megawatts of bifacial last year and it currently has hundreds of megawatts' worth of orders.

“We’re at this point where there’s a lot of leading suppliers that have scaled bifacial capacity and there’s a whole bunch of suppliers doing pilot projects in China, the U.S. and Europe,” said Jade Jones, a senior solar analyst at Wood Mackenzie Power & Renewables. “The barrier that’s happening right now is figuring out how to standardize power estimates for these products across the board.”

Once the standard is in place, it will be easier for the industry to assess the benefits of bifacial modules against their cost. Monofacial and bifacial modules are moving closer to cost parity. Bifacial requires few manufacturing tweaks, such as replacing the traditional backsheet with glass, compared to monofacial production.

“I think it’s similar to single-axis tracker adoption. You have a little bit of a higher cost, but you deliver a higher energy yield. This is a levelized cost of energy solution,” said Fang. “This will take a little bit of time, probably one to two years for the technology to become established with customers, as well as by tracking real performance data. Once that is realized, we think the switch to bifacial will take off very quickly.”

Kimberly Weaver, Array’s lead engineer of bifacial products, said manufacturing costs have come down enough to make bifacial prices comparable to monofacial. “That’s where this high visibility on bifacial is coming into play,” she said.

But a dearth of actual field installations means more data is needed. Until that rolls in, barriers to adoption remain.

“People still don’t quite understand how to utilize them, therefore the manufacturers don’t see the cost-benefit of making them in volume yet,” said Stewart.

Array will start collecting data on its newly installed panels next week. The tracker company said it should have enough data by November to come to some conclusions about the technology.

*This number has been changed to reflect efficiency numbers from Longi.

The top-5 module suppliers to the PV industry shipped more than 20GW of modules during the first half of 2018, representing Y/Y growth of 10%.

Several years ago, we defined the criteria for being in the Silicon Module Super League (SMSL) as having >4GW shipments annually. Several of the companies in the top-5 exceeded 4GW in the first six months of this year alone.


In global market shipment of 1H-2018, Jinko Solar leads with shipment of 4.8 GW, followed by JA Solar, LONGi Solar, CSI, Trina Solar, Hanwha Q Cells, Risen, GCL Integration, Suntech and Talesun. In pace with the rapid increase of mono-crystalline products, LONGi Solar climbed from No. 7 in 2017 to 3rd place in the H1-2018 ranking.

LONGI Solar moving up 4 places in the ranking within 6 months can be attributed to its continuous capacity expansions in China and overseas production, as well as its rapidly growing brand awareness. The company further secured its No.1 position in the China’s domestic market, amongst strong competition.

Mono-crystalline products are quickly gaining recognition and popularity in China because of their inherent benefits of better cost performance and this trend is rapidly spreading outside of China. Matched with keen competitive pricing of mono cells and modules, PV products based on mono-crystalline technology is estimated to capture 47% of the total market in 2018 and projected to grow to around 60% in the following few years. As a frame of reference, mono-crystalline product share was 28% in 2017.

Overall, it forecasts total PV demand of 83 GW in 2018.

Some crops grow better under raised solar panels than they do in full sun

Honey producers Travis and Chiara Bolton keep bees at three solar farms where developers seeded native plants underneath and around panels. “The advantage to these sites is that they are intentionally planted for pollinators,” says Travis Bolton. “At these sites they’re really trying to get them back to a native prairie, and that’s a benefit to us.”

Native plants have replaced turfgrass and gravel as the go-to bedding for solar gardens in Minnesota. More than half of the 4,000 acres (1,600 hectares) of solar farms built in 2016 and 2017 feature native plants that not only benefit pollinators but also beautify the site.

Although Minnesota may be in the vanguard of encouraging solar farm developers to grow native plants, it is far from the only place studying how solar farms can harvest more than just energy. Universities in the United States, Germany and elsewhere are testing the concept of “dual use farming,” as some advocates call it, where crops grow below canopies of solar panels. They are finding they grow just fine—and, in some cases, better than crops in full sun.



Adding plants to solar farms offers all kinds of benefits to the facilities’ primary aim of reducing carbon emissions and expanding renewable energy. And native and crop vegetation can help improve the health of pollinators, which are threatened by habitat loss, pesticide poisoning, poor nutrition, disease, decreased genetic diversity and a host of other factors. As a result, managed honeybee colonies used for honey production declined from 5.7 million in the 1940s to around 2.7 million today. Pollinators have an enormous impact on the economy, too, by annually contributing US$24 billion to the nation’s economy.

“Solar development is happening on a massive scale as lands are being converted from agricultural land or unused land into solar projects,” says Jordan Macknick, energy-water-land lead analyst with the National Renewable Energy Laboratory (NREL), which funds research on the impact of native and crop plants grown in solar farms. “That represents an amazing opportunity to improve our agriculture and improve our food security while developing energy at the same time.”

NREL-funded research found growing native plants could reduce land acquisition costs, reduce weed control costs and slow panel degradation.



Pilot projects in Massachusetts, Arizona, Germany, China, Croatia, Italy, Japan and France look encouraging for mixing crops with solar panels, referred to as “dual use” farms because they offer both agricultural and electrical production. “So far, the pilots have been extremely successful in showing that you can grow crops and make electricity at the same time,” Macknick says.
A dual-use farm operated by the University of Massachusetts–Amherst grows a variety of plants—peppers, beans, cilantro, tomatoes, swiss chard, kale—below solar panels elevated roughly 7.5 to 9 feet (3 meters) or more above ground to allow for easier harvesting mainly by hand. Project researchers have found that 1- to 1.2-meter (3- to 4-foot) gaps between panel clusters led to crop yields almost the same as what they would have been in full sun sites.

One of the first concepts for mixing solar and agriculture, dubbed “agrophotovoltaics” (APV), was developed more than three decades ago by physicist Adolf Goetzberger. The research institute Goetzberger created—the Fraunhofer Institute for Solar Energy Systems—finally got around to building its own dual-use farm on one-third of a hectare (just over three-quarters of an acre) at an existing farm cooperative a few years ago. The institute elevated 720 solar panels high enough for farm machinery to harvest plants underneath and nearby, according to a 2017 press release.

The researchers planted wheat, potatoes, celeriac and clover grass in the open and under the panels and compared the yields. Solar shading decreased production 5.3 percent to 19 percent. Yet electricity from the panels, which capture both indirect and direct light, was used to power a crop processing plant and electric farm machinery, offsetting those costs and increasing land use efficiency by 60 percent.

Cumulative PV capacity installed under the scheme reached 90 MW at the end of June. Of this capacity, around 27 MW were deployed in the second quarter alone.

The State Agency on Energy Efficiency and Energy Saving of Ukraine (SAEE) has revealed that total installed capacity under the country’s net metering scheme topped 90 MW at the end of June 2018.

At the end of March, cumulative capacity under the mechanism stood at around 63 MW, which means that another 27 MW of residential and commercial PV systems were deployed in the second quarter alone.

Overall, 4,660 rooftop PV arrays were installed under the scheme at the end of the latest quarter, in which new additions totaled 543. This compares to 3,553 projects at the end of March and around just 200 new projects in the first quarter of 2017.

Total investments in this market segment, said SAEE, have reached a total of €88 million. “This activity is pleasantly impressive and proves that in June 2015 we introduced an effective stimulus – a green tariff for private solar energy power generators with a capacity of up to 30 kW,” said Sergey Savchuk, head of SAEE.

Ukraine’s net metering mechanism, which is open to PV installations with a capacity of up to 30 kW, was introduced under the law №514-VIII, which came into effect in April 2015.

Ukraine’s total operational PV capacity reached around 841 MW as of the end of 2017, according to new provisional numbers released by the Ukrainian government.
