Backsheets are the backbone of module reliability. These films, typically made of polymer composites, are one of the most important process consumables in module assembly. Thus they influence cost as well as reliability of the solar module.
For our 2nd TaiyangNews Market Survey on Solar Backsheets, 12 companies, including the market leaders, have responded:
Agfa-Gevaert NV, Belgium
Aluminium Féron GmbH & Co. KG, Germany
Crown Advanced Material Co. Ltd, China
Cybrid Technologies Inc, China
Hangzhou First PV Material Co., Ltd, China
Jingmao Technology Co., Ltd, China
Krempel GmbH, Germany
Jolywood (Suzhou) Sunwatt Co., Ltd, China
Royal DSM Group, The Netherlands
Shingi Urja, India
Toyal Zhaoqing Co., Ltd, China
ZTT Group, China
The above list of participating companies in this year's survey has 6 new entries compared to the previous publication, for which 8 companies sent us their product specs. The new entrants to the survey are AGFA, Crown, Jingmao, Shingi, Toyal and ZTT.
The listed products in our survey are based on various film configurations – from one to several layers, films and coatings. The choice for the polymer chemistry is also quite wide.
A typical backsheet has a 3 layered structure, in which the PET core film is sandwiched between two protective layers. Based on the chemistry of the protective layers, the backsheets can be roughly segmented into 2 categories: Fluoropolymer based backsheets contain at least one fluoropolymer film to protect the PET core, while non-fluoropolymer based backsheets are free from halogen components. Our 2018 survey includes 62 products, with 41 in the fluorosegment and 21 in the non-fluoro segment.
Market survey on Solar Backsheets in detail:
After an introduction (1) and an overview with basics, types, history and suppliers of backsheets (2), we provide at backsheet market update(3) and look in detail on the different backsheet components(from core layer to inner and outer layers and technology developments) (4). The market survey includes product descriptions for the different backsheet models listed (5). A conclusions chapter analyses the survey content (6), followed by a table with detailed product specifications (7).
