TwinPeak 2S Mono 72 Silver

REC Group, the largest European brand for solar photovoltaic (PV) panels, announced the production start of two new monocrystalline products based on its award winning TwinPeak technology.

Using p-type monocrystalline PERC cells, the 60-cell TwinPeak 2 Mono is rated up to 320 Wp and the 72-cell TwinPeak 2S Mono 72 up to 380 Wp. The new panels bring heightened efficiency to REC’s portfolio and will be the company’s first products to come with a new, extended warranty.

Building on REC’s long experience with half-cut cell technology, the new mono products offer increased power output per square meter and improved performance in shaded conditions. This makes the REC TwinPeak 2 Mono a solid choice for residential and small commercial rooftop installations where high power is required in limited space. The larger, but at 22 kg still lightweight, REC TwinPeak 2S Mono 72 enables large commercial and utility installations to benefit from the lower balance of system costs inherent in this format.

Order volumes for the new panels are already buoyant, early evidence of the clear product benefits and REC’s continued position as a leader for half-cut PERC cell technology. REC Group was the first manufacturer to introduce half-cut cell solar panels to mass production in 2014. To date, more than 2 GW of REC TwinPeak solar panels with half-cut cells have been installed around the globe.

“For two decades, REC Group has been continuously pushing the boundaries of solar cell technology. With the launch of TwinPeak in 2014, we were the first to commercialize half-cut cell technology. Following on from the launch of the N-Peak earlier this year, we are now transferring our years of expertise into mono-PERC products,” says Steve O’Neil, CEO at REC Group.

The new products come just four months after REC began production of its brand-new N-Peak Series – the world’s first n-type mono solar panel with half-cut cells and twin design. As with the N-Peak, the new mono products are manufactured at REC’s production site in Singapore.

This study says Midsummer’s thin-film PV production is one-tenth the global warming potential of silicon module production

CIGS module midsummer

A new study commissioned by thin-film solar provider Midsummer shows that its proprietary flexible CIGS thin film solar module manufacturing process might be more environmentally friendly than other solar module production processes.

The recent study by Swerea IVF, a Swedish industrial research institute, claims that Midsummer’s rapid sputtering production process for thin film solar modules can result in a global warming potential (GWP) that’s one-tenth that of the silicon modules.

Midsummer´s flexible CIGS solar modules do not consist of any glass or aluminium materials, reducing material consumption significantly. One reason for the low carbon footprint is the extremely thin light absorbing CIGS layer. Midsummer uses less than 1um (one micrometer, 0.001 mm) of CIGS materials in its production process and this enables not only a fast production process, but also low energy consumption.

The objective of Swerea IVF’s Life Cycle Assessment (LCA) study was to understand the environmental impact of Midsummer’s production method for flexible CIGS solar module in a life cycle perspective. The results showed much lower CO2 emission compared not only with similar modules made of silicon but also with other thin film technologies.

The study has been reviewed and approved by a Swedish independent third-party institute; Miljögiraff AB.

Details on LONGi Solar’s latest bifacial PERC solar module advances

LONGI bifacial module production

Since its founding 18 years ago, LONGi Solar has focused on the continuous development of mono technology, and its Hi-MO range of monocrystalline PERC modules is known for high power, low LID and high energy yield. Hi-MO3, the latest addition to the family launched in 2018, is a next generation bifacial module built with monocrystalline half-cut cells. Hi-MO2 offers the same bifacial mono-crystalline PERC technology in a traditional full cell layout.

Based on a mono PERC cell, research engineers in LONGi pioneered a change in the printing technique with the use of local aluminum fingers on the rear side. This allows incident light on the rear of the panel to enter the cell and realize bifacial photoelectric conversion. Unlike the all-aluminum opaque rear side of monofacial PV modules, bifacial modules have higher total power generation efficiency.

As of August, 2018, LONGi R&D has exceeded 23% front-side efficiency of its bifacial PERC cell, while rear-side efficiency reached 18% and bifaciality surpassed 82% – all industry-leading milestones.

Bifacial Gains: How much will bifacial modules add to solar tracker value? We are about to find out

LONGi Solar is among a select handful of PV manufacturers with the technical knowledge, experience and financial strength to take its R&D laboratory achievements to mass production. Dr. Lv Jun, Vice President of LONGi Solar, said: “The development pace of the efficiency of bifacial cell is amazing. So far, mass production efficiency of bifacial cell has exceeded 22%, increasing up to 0.2% every six months while bifaciality has remained above 75%.”

LONGI bifacial module results

In addition to efficiency improvement, LONGi Solar bifacial modules operate at a high level due to lower operating temperatures. Dr. Lv Jun added, “We have been researching the application performance of bifacial modules. Our field tests in Taizhou, China showed average operating temperature of bifacial PERC modules to be 1~2℃ lower than that of monofacial PERC modules and the maximum operating temperature of bifacial PERC modules is 3~6℃ lower than that of conventional PERC modules.” The low operating temperature and low irradiation performance directly translate to higher power generation.

Bifacial performance results

LONGi says bifacial modules significantly increase the energy yield of power stations by 5%~30%, depending on the environment. The gain from bifacial modules also varies in different regions and is strongly correlated with ground surface reflectivity, installation height, latitude, module size, mounting, and inverter choices in the design of the bifacial system.

LONGi Solar has done extensive fields tests in power stations, comparing bifacial and monofacial module performance on standard and single-axis tracking systems. On the cement ground of a power station in Taizhou, bifacial PERC yields 11% more energy than monofacial PERC modules. In the horizontal-single-axis tracking system of a power station in Qinghai, bifacial PERC yields 19.27% more energy than a conventional product. And under inclined irradiation conditions in a power station in Turpan, bifacial PERC module yields 23% more energy than a monofacial module. These rich test data are essential in modeling energy yields in bifacial modules and contribute to the bankability of LONGi Solar products.

As winter approaches in the northern hemisphere, the snowy conditions will significantly increase the energy yield of bifacial PERC modules. Tests by LONGi Solar showed energy yield increase of 62%~188% during snowfall, 272%~603% during snow melting, and 14%~34% when snow-free. In addition, bifacial PERC modules can significantly reduce the snow-melting time, and reduce the energy loss and reliability risks caused by snow.
