Top-10 solar cell producers of 2018 Wiring solar panels: Calculate in series and parallel wired PV solar panels

PV-Tech.org We have a group of four companies (JA Solar, Trina Solar, JinkoSolar and Canadian Solar) that can be considered as a globally recognized manufacturer of integrated cell / module modules, all of which produce multi GW (1000 MWp) cells plants in Southeast Asia, with the Domestic Chinese third-party providers for example, be supplied by Tongwei and Aiko.

JA Solar and JinkoSolar have largely repositioned themselves as manufacturers of p-mono PERC cells, and Trina Solar is in the process of making the change. Canadian Solar is still a kind of multi provider.

LONGi Solar is also unique in our top 10 list in many ways, especially in terms of the entire value chain (ingot to module), but especially in terms of the size and positioning of its ingot-pulling business in China.

The only thin-film manufacturer in this ranking First Solar has impressively improved its efficiency in mass production in 2018.

PV CellTech 2019 to explain cell production in 2019/2020

Going into its fourth year, the forthcoming PV CellTech 2019 conference (Penang, Malaysia, 12-13 March 2019) will again be the go-to event of the year to hear from the CTO’s of the top-10 cell producers, many of the new n-type companies seeking to disrupt mainstream cell technology in the next 12-18 months, and all the leading equipment and materials suppliers that are key to cost-reduction and efficiency-gains.

PV CellTech has now become the PV Technology Roadmap of the industry, and for the exclusive attendees, offers market insights and networking that drives much of the leading company strategies going forward. The event was sold-out during 2018, so book a place early to ensure participation.

 Modules connected in series

Interconnection of any number of Modules is usually done as a series connection. In this case, the negative terminal of one Module is connected to the positive terminal of the other Module, so that all Modules are supplied with the same current. The resulting total stress is then the sum of the partial stresses. The series connection of Modules is often referred to as a series connection.

The parallel connection of Modules makes it possible to individually increase the capacity(A) while maintaining the same voltage

Switch Modules or cells in parallel

In parallel connection of Modules, the positive pole is connected to the positive pole and the negative pole to the negative pole. The capacity (A) of the individual Modules then adds up while the total voltage corresponds to the voltage of the individual Modules. Basically, only Modules with the same voltage should be connected in parallel.

The parallel connection of batteries makes it possible to individually increase the capacity while maintaining the same voltage

Switch batteries or cells in parallel

In parallel connection of rechargeable batteries, the positive pole is connected to the positive pole and the negative pole to the negative pole. The charging capacity (Ah) of the individual batteries then adds up while the total voltage corresponds to the voltage of the individual batteries. Basically, only batteries with the same voltage and acid density should be connected in parallel with the same state of charge and the cable cross-sections and cable lengths should be exactly the same
