In this page we will teach you how to wire two or more solar panels in parallel in order to increase the available current for our solar power system, keeping the rated voltage unchanged.

When your panels have the same current but different voltage, you need to wire your panels in series. This is because the voltage gets added up,

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

I made a series of demo videos showing what happens when you wire mismatched solar panels in various configurations. I''m now trying to explain the "why" behind what we saw. I thought

The short answer is, yes, you can mix solar panels that have different wattages. But it is not usually advised, because mixing different wattage panels reduces the

You would have to look at open circuit voltage of existing panels and new panels, if voltage is too different you will lose a lot of efficiency. You might need to add a new charge controller, which...

Panels in series limit the current to that generated by the smaller panel, voltage is the sum of the panel volts. Thus panels in series should have similar current outputs.
