100W Solar Panel Kit 12V Battery Charger 10-100A LCD Controller For Caravan Van Boat
A part of the review has been auto-translated.
The boxes arrived damaged, but the solar panels were not damaged. There's no way to identify the amperes on the controller. After assembly, according to my measurements, the 100W solar panel can only produce 20W even in strong sunlight. Where's the 100W power? It's a big scam!
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.
Solar-Panel-Kit-12V-Battery-Charger-10-100A-LCD-Controller-For-Caravan-Van-Boat Looks good but 100w never with this panel. But for me he will do his job to recharge the 12v battery, but think himself that if he can deliver 30 watts is enough for me. Despite that I am very satisfied with the purchase. Everything came in one piece.
Produits de bonne qualité le contenu du colis correspond bien à la photo . A l'usage la charge est plus que correcte y compris par temps de pluie. Reçu une semaine avant la date prévue
Recommendably fast-track. Ordered 24.8.021 delivered by courier 3.9.2021 - so far I have not tried the load with load, measured without load outside the window.K.
Nice package, fast delivery, today it was sunny day, i tested in very bright sunlight, but unfortunately is not 100W power. I think is maximum 20-30W.
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.
The product arrived at the specified date, but unfortunately the solar panel does not work. Corresponding photos submitted. As a result, I was asked once again to submit photos. Photos show solar panel at full sunlight with connected voltage meter showing 0Volt. So photos submitted again. Until today no reaction! Too bad
as you can see in my picture, Solar panel si working but solar charge controller is not, please seller be reponsive to this😓😓,
la caja llegó un poco maltratada, pero el producto llegó bien, falta probarlo a ver si funciona bien
