Putting the two dissimilar panes in parallel is not a good idea. Mostly, the higher voltage panel will deliver most of the current and the low voltage panel does little. If the two panels have similar current ratings but different voltage rating, you can put them in series to get the sum of the voltages at the single current rating.

6 FAQs about [Solar panels have different voltages]
How many volts does a solar panel produce?
Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel. When we are asking how many volts do solar panels produce, we usually have this voltage in mind. For maximum power voltage (Vmp), you can read a good explanation of what it is on the PV Education website.
What is a typical open circuit voltage of a solar panel?
To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C). All the PV cells in all solar panels have the same 0.58V voltage. Because we connect them in series, the total output voltage is the sum of the voltages of individual PV cells. Within the solar panel, the PV cells are wired in series.
Do solar panels have a 12V voltage?
This might sound weird, but both are correct and useful: Nominal 12V voltage is designed based on battery classification. With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery.
How many volts is a 36 cell solar panel?
36-Cell Solar Panel Output Voltage = 36 × 0.58V = 20.88V What is especially confusing, however, is that this 36-cell solar panel will usually have a nominal voltage rating of 12V. Despite the output voltage being 18.56 volts, we still consider this a 12-volt solar panel.
Does solar panel voltage fluctuate?
Yet, the collective voltage output from the solar panel array can fluctuate depending on the number of modules linked in series. Each solar cell has a specific voltage output, and connecting them in series increases the total voltage output of the panel.
How to calculate solar panel output voltage?
If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel). Here is this calculation:
