Veja como fazer uma placa de energia solar alimentar um conjunto de iluminação com leds. Ligamos 4 pequenas placas de um painel solar fotovoltaico em um painel com 30 leds comuns.
Construir um painel solar residencial é uma das melhores formas de se economizar na conta de energia elétrica, um gerador de energia solar tem a vantagem de fornecer energia renovável a um custo geralmente menor que o da concessionária de energia.
O painel de luz solar usado no vídeo é bem pequeno e fornece uma tensão e corrente proporcionais ao seu tamanho. Montamos um kit que custa pouco apenas para mostrar como funciona e como fazer.
Foram ligados em série para multiplicar o potencial e permitir ligar todos os leds ao mesmo tempo. Medimos a tensão com o multímetro e mostramos o resultado da ligação deste kit.
Quanto ao preço de placas solares, há vários fatores envolvidos, dentre eles o rendimento da placa, informação nem sempre clara e disponível no momento da compra e venda.
