It is a good and versatile product. The three sections are wired in parallel, so if a shadow happens to fall on one or two sections it still yields 2/3 or 1/3 of power. On a sunny early spring day (at 20 °C, 650 W/m2) at a maximum power point (MPP) I get 75 W, which is very decent. The wires that come with it are quite thin, so the longer 3 meter wire loses 5.7 W of power at MPP 75 W, which would be about 10% of power at 100W - so it might make sense to replace it with a thicker wire when feeding a power pack. I have modified the shorter wire with crocodile clips replacing them with MC4 connectors, so that a regular small MPPT solar charger can be attached for more efficient charging of a car battery.
