In the Shingled technology, the cells of each column are located in series and, in turn, the columns are connected in parallel, which significantly reduces the impact of shadows that partially cover areas of the panel, losing less production than other technologies.
Increased Shade Tolerance - Conventional solar panels have individual cells connected in series, so when a portion of the solar panel is shaded, it can have a significant impact on power output levels. By configuring solar cells in shingles, they can be grouped and configured in parallel, thus significantly reducing the losses caused by shading.
So, if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series, the voltage of the series would be 80 volts, while the amperage would remain at 5 amps. Putting panels in series makes it so the voltage of the array increases.
Better Mechanical Properties - Static and dynamic load tests have shown that the shingle method is more resistant to failures due to external forces applied to the solar panel than conventional solar panels. In addition, the conductive adhesive used on the stacked shingle cells helps reduce internal stresses due to thermal expansion.
If you, however, need to get higher current, you should connect your panels in parallel. Should you need both a higher voltage and a higher current, you have to apply both connection modes, which means that a part of your solar panels should be wired in series, while the remaining ones are to be wired in parallel.
The other system components, such as a charge controller, battery, and inverter. There are two main types of connecting solar panels – in series or in parallel. You connect solar panels in series when you want to get a higher voltage. If you, however, need to get higher current, you should connect your panels in parallel.
Putting panels in series makes it so the voltage of the array increases. This is important because a solar power system needs to operate at a certain voltage for the inverter to work properly. So, you connect your solar panels in series to meet the operating voltage window requirements of your inverter.

For example, let's say you have 3 identical solar panels. All have a voltage of 12 volts and a current of 8 amps. When wired in series, the 3 connected panels (often called a series "string") will have a voltage of 36 volts (12V + 12V + 12V) and a current of 8 amps. In this example, the series string will have no losses.
When wired in series, the resulting series string will have a voltage of 42 volts (12V + 14V + 16V) and a current of 6 amps (the lowest current rating of the 3 panels). In this example, our series string will have some power losses because the currents of the 12V/8A panel and 14V/7A panel will get "pulled down" to 6 amps.
When wired in series, the 3 connected panels (often called a series "string") will have a voltage of 36 volts (12V + 12V + 12V) and a current of 8 amps.

Though mixing different solar panels is not recommended, it's not forbidden and things would be ok as long as each panel's electrical parameters (voltage, wattage, amps) are carefully considered.
Then yes, you can mix solar panels that have different wattages. But it is not usually advised because mixing different wattage panels reduces the efficiency and power output. Wattage Mixing Reduces Efficiency and Power A variety of wattage panels has different voltage and amps outputs.
Let us understand the concept with the help of an example. Have you ever bought a 200-watt solar panel and wondered if it can be used with your old 100-watt panel? Then yes, you can mix solar panels that have different wattages. But it is not usually advised because mixing different wattage panels reduces the efficiency and power output.
A variety of wattage panels has different voltage and amps outputs. The system always favours the lowest voltage or amp, which puts the larger panel on the back burner. This, as a result, reduces the overall efficiency and power output of your solar panel array.
Inverters also play a crucial role in how effectively your solar system can handle mixed wattage solar panels. Good quality MPPT inverters can adjust the voltage to the optimum level for maximum power output. Mixing panels of different wattages can be cost-effective and allows for customization based on space and budget requirements.
