    It arrived in almost 20 days. Same as the first board I bought only this one brings the connector for two (parallel) (IMG.01). It was only yesterday good sunshine and I tasted the Plaque. Everything like the first one: 21-23 v and 0.75 Amp with direct sun from 11:30 a.m. I put the two in parallel and measured for almost 1 hour (from 11:30 am to 12:30 pm. img.02). St Paul, 23° lat south. Now in the winter solstice (the sun is now hitting straight into the carib). The plates have been placed in an angle of +/- 45° to maximize the incidence of the sun (img.03, img.04, img.05). Measurements remained constant for 1 hr, lowering the Amperage by half as a cloud passed. Interesting to point out that with the plates in parallel the voltage drops a little, the current production of the two joints, is like 15% greater than the sum of if they are separated. (each separate produces 15Wh, the 2 joints in parallel produce 35Wh). All this was done empirically just to prove, the readings remained constant during the hour of more sunshine (img.06 & img.07)... CONCLUSIONS: Miracles cannot be expected from solar plates. There are people who think with these little ones you'll light up your whole house. But these little ones produce energy according to their size purchased with the solar plates that usually go on the roofs. I am satisfied and will buy a third already yes to put it in parallel and power a battery through a solar controller. With 3 of these plates placed in the window, they can produce 300 W per day. We'll see what we can do with that later.

    Small nice solar kit received very quickly (8 days!), which works well, but far from the pretensions announced.... I estimate the power of the panel at 20Wc, based on quick measurements with average sunshine (veiled sky), I found about 8w products.... Well, you still have to get your hands on it because the cables provided are equipped with jack plugs while the solar regulator is equipped with screw terminals... It is therefore necessary to cut the cables by clearly identifying the polarities (Plus on the wire marked with a white line) in order to be able to connect them to the regulator. The panel is more rigid than shown in the photo, so I would say semi-rigid rather than semi-flexible. But the overall result is positive for me, because it is a good small mobile solar troubleshooting kit.
