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.

  • dr.don 300W per day doesn't really make sense. Watts are already units of POWER (rate of energy usage or delivery), so there is no element of time in Watts (the "per day part). ENERGY can be measured in Watt-Hours, but there's a problem there, too. In full sun, there is never a moment this panel will provide 100 Watts. To determine how many Watts (power) the panels are providing at any moment, simultaneously measure the voltage and current and multiply. 22V X 0.75 Amps is 16.5 Watts. multiply the power by the number of hours the panels collect 16.5 Watts, and you have the quantity of energy collected. Some of that energy is lost heating the batteries and charge controller (as well as during battery usage), so even if you store 16.5 Watts for 4 hours, you may only store 55 Watt hours of energy, and in use you might only recover 50 Watt hours of the stored energy. Energy is conserved, but doesn't always go where we want it to go.

  • BG413754280 Youhave to read carefully. They are 100W kits, with 30W panels.

  • BG502556513 Good review something to look into for you, or anyone using in parallel. Read about Schottky diodes inserting these can help reduce the drop because the current from one panel can not flow into the other. Please research carefully and be sure it will work, I am no expert just a person hoping to help.

  • REXX5000 thank you so much for your share. it had excellent information on the panels and set up. you definitely know what your doing and gave me the confidence that these will do what I need them to do. I CAN'T THANK YOU ENOUGH FOR YOUR VERY INFORMATIVE REVIEW 😊 🙏🏼 👍🇮🇪

  • REXX5000 dr. don... I agree with what you ate saying but for the money these are worth it. like he said "you can't expect miracles out of these" and I think he meant that he can his batteries charged up to 300w per day. now I would like to know the watt hour myself as well as you, but we both would need to do our own measurements on these panels. now saying that. he still has given us A LOT MORE info than the normal person reviewing these or other things you normally read here in the reviews. now it's the charger that comes with the panels that are quoted to be 100w not the panels ( just noticed that there now) the panels are 30W max. that's why he's getting the 3rd panel so he can get it up "close on the perfect conditions" to the 100W they say it Can do. DR. DON I WOULD LOVE TO SEE YOU DO I REVIEW ON THESE IF YOU EVER GET SOME ( IM NOT KIDDING HERE EITHER) THANK you for you comment too dr. don it was full of good info as well to look out for with these or to check when you get this set. Nice one dr. don... 👍🇮🇪😁

  • Angelus Olá amigo, você tem de colocar um diodo em cada uma delas.. só no fio positivo .. o diodo tem de ter o risco no outro lado do fio do painel .. ou seja o fio que vai ligar ao controlador de corrente. Entende?

  • BG155135504 people who expect any type of so called miracle always need to keep this old adage in the forefront of their thoughts- " You get what you pay for!" lol I am amazed at the same time at how fast technology is and has been improving!
