If we have two solar panels with the same voltage but different wattage, there is no problem; they can be wired in parallel. On the other hand, if our two solar panels have both different wattage and different voltage, then parallel connection is not possible, since the panel with the lowest voltage would behave like a load, and would begin to absorb current instead of producing it, with the

FYI - you do not need a combiner box if you only have two strings in parallel. Joining the two strings with MC4 Y-connectors is all you need. A combiner box is typically only used with 3 or more parallel strings. It does act as the parallel connection. It does not act at all like a series connection.

We could connect all four together in a parallel combination (1 x 4), or connect the two 80 watt panels in series and the two 100 watt panels in series with the two series strings in parallel, (2 x 2). There are different wiring possibilities.
When choosing the best setup for your solar panel system, it's important to understand the basic differences between series and parallel connections. The main difference is how they handle voltage and current. In a series connection, the voltages from each panel add up while the current stays the same.
When building a solar power system, the panels array connection is the vital part that determines how many voltage and amps comes out from the panels.The three main methods you can connect multiple panels are connecting them in series, parallel, and series-parallel. Series Connection: When connecting multiple panels
To solve this problem and to optimize the energy performance of the entire system, it is advisable to wire two panels in series (obtaining a doubling of the voltage) and then wire in parallel the three pairs previously wired in series (so as to have doubled the voltage and tripled the current).
Note that series strings of PV panels can also be connected in parallel (multi-strings) to increase current and therefore power output. In this scenario, all the solar PV panels are of the same type and power rating.
That is connecting solar panels in parallel increases the available current of the system, so two identical panels connected in parallel will produce double the current as compared to just one single panel. But while the currents add up, the panel voltage stays the same.
