Remember, this is a pretty good number. The best panels have a Pmax temperature coefficient of around -0.3% / °C. Panels that hit -0.7% should be completely avoided. -0.43% is a good number, but the lower this number the better. The higher the number, the less efficient your panels are on the hotter days.
Since these are 2 different panels containing different amounts of cells, you can imagine that the dimensions of the individual panels will differ too. The 60 solar cell panels tend to be 10 cells tall and 6 cells wide, whereas the 72 solar cell panels are around 12 cells tall and 6 cells wide. This gives the latter a taller appearance
It can be gotten with an ammeter across the terminals of the panel. The Voc of the panel gives the value, in volts, of the solar panel's output with no load on it. It can be gotten with an voltmeter across the terminals of the panel.
In terms of voltage, an individual solar cell produces around half a volt. For comparison, a double-A battery contains 1.5 volts and a wall socket provides around 120 volts. In other words, we need a large number of cells in a panel and a lot of panels in an array.
You can see that connectors also have an IP rating. Electrical specifications are the most important part of the datasheet. This is where you can find the voltage, current and expected power output of the solar panel. The power class is a way to classify the variations of the same model based on their wattage or power rating.
