Single-glass modules with a transparent backsheet will eventually offer the lowest cost bifacial solar power, according to JinkoSolar.
The company has launched such a module this year ahead of putting it into the market in H2 2019.
“We expect the cost of the product, once fully-commercialised at scale, will be better than dual glass,” said Gulnara Abdullina, GM for Jinko’s Middle East and Africa business. The module was given a soft-launch in Abu Dhabi in January. Abdullina points out that as well as benefits for EPC firms, a single-glass approach to bifacial solar will also mean lower impact from high-temperatures.
“A single-glass panel is going to heat up more slowly. That will also contribute to a better degradation pattern and that makes a huge difference to the financial model,” she said.
“The transparent backsheet has been developed by DuPont over the course of 20 years of R&D. The advantage is that it is lighter. One person can handle it because it is 23 kg, 9 kg lighter than a double glass product,” said Abdullina. “It is framed like a standard module too so you standardise the installation, minimise the labour costs and minimise the breakage rates. All this makes a great contribution to decreasing the capex.”
The new modules will use the company’s Cheetah cells with a 400W version available soon. A half-cut cell version has already tipped the 400W mark. Jinko will match the 30-year warranty offered on dual glass modules.
The footprint and frame of the module are the same as a “plain vanilla 72-cell” panel, according to Abdullina, which means the full ecosystem of conventional trackers, clamps etc are compatible.
Data on the precise impact on the levelized cost of energy (LCOE) has been modelled by Jinko with the firm keen to hold off on publishing numbers until more field data has been acquired.
Join this webinar, presented by Andrea Viaro, Head of Technical Service Europe from Jinko Solar, the initiative partner of this webinar, as he outlines the key features and benefits of using ultra high performance modules. Viaro will discuss how Jinko Solar’s new technology innovations impact the LCOE and IRR of the PV utility-scale power plants. Viaro will be joined by Athanasios Bakalis, Group Technical Director and Nikos Sokos, General Manager MEA and Central Asia of METKA EGN, who will present a currently announced 300MW project in Spain, that will be fully powered by Jinko’s Cheetah modules and will deliberate potential cost benefits and risk assessment of the utility scale projects and what drove METKA EGN to choose Jinko’s ultra-high efficiency modules. Rubén Ron, Head of Section Solar. Iberia and LATAM, will discuss an impact of the reliability and bankability of solar panels and how world-class best practices in manufacturing and upholding stringent quality standards, coupled with the use of field-proven components can help protect solar investments.
