Wiring solar panels: Calculate in series and parallel wired PV solar panels

Wiring between solar panels (back of solar panels) When PV Modules are connected in series, the voltage adds up, but the power(A) capacity remains the same

When PV Modules are connected in series, the voltage adds up, but the power(A) capacity remains the same..

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.
