Xia announced an aggressive expansion in manufacturing capacity across all aspects of value creation with goals of producing up to 1,000 kT polysilicon, 150 GW cells and 80GW module production by 2026.
TW or Tongwei Solar produces one of the key components in any solar panel – The Cell. Prosun has taken an educational promotional angle with their Brand, reminding their buying public that Tongwei Cells have been included within their chosen Solar Panels.
3. Trina Solar
Trina Solar’s vertically integrated structure enables them to tighten quality controls from silicon crystallization through module deployment in the field, guaranteeing reliable and superior performance panels from Trina.
Vertex S+ modules from this manufacturer come with 25-year product and 30-year performance warranties due to their superior degradation rate (0.64% per year versus 0.89% from other vendors).
Trina Solar is a global total solution provider with products and services sold worldwide. They maintain local presence in each market they operate in and are bankable, having earned Tier One status from Bloomberg New Energy Finance.
JinkoSolar was established in 2006 and listed on the New York Stock Exchange in 2010, becoming one of the leading solar panel manufacturers worldwide. Their vertically integrated manufacturing processes and financial stability have allowed them to outshone competitors.
JinkoSolar stands out from its competition in terms of product quality, operational efficiency and its unwavering commitment to customers. Their cutting-edge manufacturing facilities around the globe produce world-class solar modules which withstand rigorous mechanical loading tests as well as wind pressure, snow loads, extreme temperatures and rigorous wind pressure conditions.
JinkoSolar stands apart from many module makers by producing its own ingots and wafers using high grade silicon technology. Their Tiger N-type and Neo TOPCon panels use cutting-edge tiling ribbon technology that helps push industry progress toward more advanced cell architectures.
5. Canadian Solar
Canadian Solar is one of the world’s leading manufacturers and providers of solar photovoltaic products and energy solutions, as well as acting as an international power plant developer.
This company boasts manufacturing facilities in both Asia and America and an impressive production capacity of 20GW worth of solar modules annually. Their solar panels are affordably priced while offering impressive product and performance warranties.
HiKu series modules from Solar Solutions use industry standard mono PERC half-cut cells for maximum efficiency ratings, offering multiple panel options such as bifacial modules. In low light conditions they also perform very well while losing less power under shade than competing brands.
Zhongli/Talesun is part of Jiangsu Zhongli Group, one of the top 10 photovoltaic manufacturers worldwide and one of China’s largest photovoltaic power station developers. Bloomberg Tier 1 module supplier Zhongli is also among one of China’s premier PV power plant developers.
Recently, Hebei Province unveiled plans for two megawatt-scale solar energy projects in Fuping county of Hebei province. A 5GW heterojunction solar cell line and 5 GW “photovoltaic+modern agriculture” or “agrivoltaic” project will be constructed.
