How to hook up two 100 watt solar panels.

When researching just what a 100 watt panel will get you the general answer seems to be it depends. Connect to the device you want to power. To wire two or more solar panels and batteries in parallel simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively as shown in the fig below. This will give you a parallel connection meaning the two panels will still give you the same voltage but twice the current.

If we have two solar panels with the same voltage but different wattage there is no problem. 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. A 100 watt panel refers to a solar photovoltaic module that is rated 100 watts. After all one of the top solar power kits out there is just that 100 watts.

This means that it has a power output of up to 100 watts of dc output under optimal conditions. For example a 110ah battery should never be connected to a panel more than 11w without a solar controller and if you are using a solar controller you do not need a blocking diode. Wire the ve positive terminals together wire the ve negative terminals together. Since each panel is 12v and the battery bank you want to charge is 24v then you need to series your system to increase the voltage.

In a solar power system the higher the voltage and the lower the energy losses along the cables to know the maximum system voltage we usually just need to turn the panel and read the label where the value is reported. And it does to a certain extent but on the page we re going to give you a rough estimate and guide to what a 100 watts of solar power will provide you. After these clarifications let s see how the series connection takes place. The rule of thumb when connecting solar panels directly to a battery is never connect more than c 10 watts where c is the capacity of your battery.

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. By connecting multiple solar panels in series we increase the system voltage.
