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.

Chegou em quase 20 dias. igual que a primeira placa que comprei só que esta traz o conector para duas (paralelo) (img.01). Só ontem fez bom sol e provei a Placa. Tudo como a primeira: 21-23 v e 0,75 Amp com sol direto das 11:30 am. coloquei as duas em paralelo e fiz medição durante quase 1 hora (das 11:30 am até 12:30 pm. img.02). São Paulo, 23° Lat sul. Agora no solsticio de inverno (o sol agora está batendo direto no caribe). As placas foram colocadas em angulo de +/- 45 ° para maximizar a incidência do sol (img.03, img.04, img.05). As medições se mantiveram constantes durante 1 hr, baixando a Amperagem até pela metade quando passava uma nuvem. Interessante salientar que com as placas em paralelo a tensão baixa um pouco, as a produção de corrente das duas juntas, é como 15% maior do que a somatória de se estiverem separadas (cada uma separada produz 15 Wh, As 2 juntas em paralelo produzem 35 Wh). Tudo isso foi feito de maneira empirica só para provar, as leituras se mantiveram constantes durante a hora de mais sol (img.06 & img.07)... CONCLUSÃO: Não se pode esperar milagres de placas solares. Tem gente que acha que com estas pequenas vai iluminar toda sua casa. Mas estas pequenas produzem energia de acordo a seu tamanho compradas com as placas solares que costumam ir nos telhados. Eu estou satisfeito e vou comprar uma terceira já sim para coloca-la em paralelo e alimentar uma bateria por meio de um controlador solar. Com 3 destas plaquinhas colocadas na janela podem chegar a produzir 300 W ao dia. Já veremos o que da para fazer com isso depois.

Not quite a 100 watts. I have 4 of these panels and they will produce 14 volts in full sun light. I have them charging to 12 volt batteries in parallel. With the 4 it takes 2 days to top them off.

Product arrived in a very short time, not even a week, product as described all compliant, tomorrow I will try it'. Only flaw that the connections are not waterproof!

Prodotto arrivato in tempi brevissimi, nemmeno una settimana, prodotto come descritto tutto conforme , domani lo provero' . Unica pecca che le connessioni non sono waterproof !

Arrived everything as pictured, yet to try. the only note could be that at least a sheet with drawing or a scheme did not spoil, however for the rest everything ok. Thanks

Arrivato tutto come da foto, ancora da provare. l'unico appunto potrebbe essere che almeno un foglietto con disegno o uno schema non guastava, comunque per il resto tutto ok. Grazie

Very good. I'll ask for a couple more

muito bom vou pedir mais uns 2
