The better they are matched the less loss.
Combining different size solar panels.
The vortex solar pool panel has 3 standard manufactured sizes.
4 x12 4 x10 and 4 x8.
They can be wired in parallel.
This diode does lose about 5 percent of the power 5 volt drop so more with a 6 volt system less in a 24 volt 5 6 about 15 percent 5 24 about 2 percent.
If you place in series the 85 w panel amps will be limited to the amps of the 80w panel.
To design a solar pv system for any household it is necessary to consider several parameters like the available solar resource amount of power to be supplied by the system solar panel efficiency autonomy of the system off grid or connected to the grid as well as the selection of components like inverters batteries and controllers.
Voltage power max vpmax is not too different you can parallel them.
Completely discharging it over time.
But at night the solar panel looks like a resistor and will slightly discharge the battery.
So they usually put a diode between the panel and the battery.
If we have two solar panels with the same voltage but different wattage there is no problem.
Beyond the analysis of these components there is.
If this is the case the solution is to combine different panel sizes to accommodate for complex roof designs.
