Combining Solar Panels Of Different Wattage

Combining solar panels of different wattage.

When just looking at residential solar panels the top wattage. If we have two solar panels with the same voltage but different wattage there is no problem. The solar panel with the highest watt is the sunpower e series a commercial solar panel line. Connecting them in parallel may back bias the smaller panel and damage it.

The top panel in the e series comes out at a whopping 435 watts. Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark. They can be wired in parallel. You can use solar panels with different wattages and brands but you have to connect them correctly.

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. 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.
