Combining Solar Panels Of Different Wattage

You can use solar panels with different wattages and brands but you have to connect them correctly.

Combining solar panels of different wattage.

You have two different higher voltage solar panels i e one 100w 24v and one 200w 24v that you want to connect to the already working 12 v solar power system comprising the two 12v 50 w solar panels connected in parallel from the previous scenario see the picture above.

The top panel in the e series comes out at a whopping 435 watts.

Connecting them in parallel may back bias the smaller panel and damage it. But if these are indeed panels strings of solar cells then the voltage of the larger panel will probably be a lot higher than that of the smaller panel. If we have two solar panels with the same voltage but different wattage there is no problem. 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.
