Energetica India 89 - May 2020

E nergetica I ndia : Have there been any disruptions in the solar supply chain in China due to the coronavirus? How is Jinko Solar managing the current situation? N aushad S aifi : The outbreak had up to a certain extent impacted the material supply, labor and logistic operations. But situation has improved a lot now, espe- cially for JinkoSolar. We are fully oper- ational, manufacturing & delivering for clients across the globe. When it comes overall situation in China, top solar mod- ule suppliers are less affected. But tier two suppliers will face challenges in coming time. Since nowadays, clients are more in- clined towards high efficiency solar module technology, it is estimated that Tier 1 suppliers will have fully booked capacity for high efficiency and quality modules. While Tier 2 suppliers will find this opportunity to invest into manufac- turing upgradation. JinkoSolar has been successfully able to manage this situation with its inherent practices like to keep tight & favorable control over cash flow, to manage sup- ply chain well to fulfill signed orders & to strive for more valuable orders. JinkoSo- lar is also upgrading its solar module offerings with the help of its R&D driven innovation strategy. It will easily sail us through these tough times. E nergetica I ndia : With bifacial solar modules costing more than mono facial modules, how do Jinko Solar’s bifacial modules fare in achieving low LCOE? N aushad S aifi : High Energy Density is what benefits everyone on any ground mounted Solar PV Installations, which can be achieved by using High Efficien- cy Solar PV technologies like Bifacial PV Modules. Bifacial Technology Module has got the advantage of absorbing both global hor- izontal irradiation on the front side of the module and diffused/reflected irradiation on the rear side of the module. Depend- ing on the type of installation, Texture of ground surface & location, albedo factor varies the range of gain in specific ener- gy yield when compared to Mono Facial modules. Jinko Solar has done an analysis with all possible ground textures within our Hain- ing factory at China and noticed the gain of energy with Bifacial modules varies up to 19% and the same was ratified by 3rd party agencies. Out of available different models (dual glass / transparent back sheet) in Bifa- cial Modules, for tropical climatic zones like India, it is preferred to use transpar- ent back sheet which always gets the benefit of resembling existing conven- tional Solar PV modules. Swan Bifacial Transparent back sheet modules have product warranty of 30 years due to high reliable characteristics of the materials being used with POE as encapsulant and PVF – Tedlar based back sheet with fluoric materials adding more value when compared to conven- tional encapsulant and back sheets. This even helps in obtaining lower LCOE with the reduced economics of CAPEX- &OPEX calculations. Reduced linear degradation on Bifacial modules is one other advantage over Mono facial modules to have high spe- cific energy yield on any specific year during the life of the plant. Acceptability on these Bifacial technologies is getting wide-spread across the globe. It is ex- pected to capture the majority market share technology by 2025. Swan or Tiger Bifacial Modules ranging at power class 385-405 Wp or 450-470 Wp exhibit higher energy densities on the surface which has low soil moisture, which in turn increases the reflectivity sensitivities of the soil to produce more energy from the rear side of the Bifacial module. E nergetica I ndia : Which of Jinko Solar’s products is the most favorite amongst its Indian customers? N aushad S aifi : Our Cheetah Mono PERC series has received tremendous accep- tance across the globe. Cheetah has two variants Full Cell & half-cell. Full cell wattage ranges from 390 Wp to 410 Wp & Half Cell wattage – 395 Wp to 415 Wp. Our esteemed clients across all segments in India (Utility, Commercial & industrial and rooftop) have entrusted in Cheetah modules, due to its high effi- ciency and ability to save BOS Cost and deliver more generation in limited space. Going forward, we are confident that our newly introduced Tiger series is poised to become the preferred product for up- coming projects in India. energetica INDIA- May_2020 19 INTERVIEW
