    It arrived in 15 days from payment to São Paulo. Well packaged (Photo 1). All that promises have arrived (Photo 2). It's quite simple but good quality, but... does it really workjQuery1113022054600695476134_1626302510814?. So I was already putting it in the inside of the window with glass that is not translucent (and to thatch dirty), to test with 11 o'clock sun focusing directly on the window. The measurement stayed between 19 and 22 volts (photos 3 and 4), while releasing a current between 0.25 and 0.35 Amp (photo 5). And then with direct sun at the right angle the plate released 0.80 ampere of media with little oscillation during the 5 minutes that lasted my measurement. At 5pm I wanted to see the behavior of the plaque only with the ambient light of the end of the day. Displayed a voltage of 15 volt, demonstrating sensitivity, but a pyphic current of 0.02 Amp (pictured 6)... eeeeh... no solar plate works at the end of the day (Now in São Paulo the sun falls before 18 Hs). I'm not an expert in solar energy or even electricity. I've just been trying to inform myself and I've done these empirical measurements trying to figure out how interesting this little panel can be. If we follow the relationship where W = volt X Amp, that plate gave us 17 to 18 Watts when it was exposed directly to the sun. Following the six-hour design and 20% losses, we can consider 80 Wh/day. I made the equivalence with a 100 W Resun Card (1 X 0.7 m.) and gave a similar performance. If we consider buying 6 of these small panels to cover the same creak as Resun, we'd spend twice as much. My friends, the purpose of these small panels are others (mobility, small designs,...). This particular one does not even have USB outlet and needs solar controller. Direct light performance is adequate. It should improve in the summer and it is worth pointing out that I did not take the plastic that protects the plaque (a note says take off). I liked it and already ordered another one to put in parallel.

    items as described, came well packaged and arrived in good condition, I look forward to seeing how well this will maintain the charge of my deep cycle battery.

    Έφτασε σχετικά γρήγορα και σε καλή συσκευασία. Το πάνελ το περίμενα λίγο μεγαλύτερο. Δεν το έχω δοκιμάσει ακόμη.

    Panel Looking good, measures 18 volts in full sun, no amps or watts measured yet. but will never give 100 watts as advertised with this small size. but just needed for keeping charge in battery als trickle charger so no problem.

    27 days to canaries, no customs payments, well for that, I have not tried it, I thought it was bigger the solar panel, buy 2 panel, controller x 2 I do not know if it is 100 w??? , at least if the seller tries to contact me, thank you

    11 days from order to delivery That's super! Works perfectly, too. The packaging is also always better.

    De levering was redelijk snel maar het pakket is beschadigd en ook de inhoud zoals de foto's bewijzen.
