Connecting Different Wattage Solar Panels Together

Is it ok to connect a 100 watt and a 45 watt solar panel together.

Connecting different wattage solar panels together. Connecting different solar panels in a solar array is not recommended since either the voltage or the current might get reduced. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. Solar power authority staff we recently received the following question from one of our users. 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 relative consequences.

Then they are connected to the charge controller or to the inverter of the solar system. And what is the best way to do this to charge a battery bank the quickest. Connect only in series panels of the same brand and of the same current connect only in series panels of the different. Therefore if you are planning to use dissimilar panels try to pick ones with similar voltage and current.

For this example i am showing you connecting panels that are for a 12 volt system. There are 3 ways to connect solar panels. Therefore when connecting different solar panels to minimize the losses. If we have two solar panels with the same voltage but different wattage there is no problem.

Connecting different watt solar panels by. Connecting solar panels in parallel wiring solar panels in parallel implies connecting positive terminals of each panel together and wiring the negative terminals of each panel together as well.
