how it works:

simple working principle of the solar street light, is using the principle of v shall be made of solar panels ( Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 Panels during the day to receive solar radiation and convert it into electricity, through the charge and discharge controller' This controller is intelligent to adjust the working voltage of solar panels, always work in V - making solar panels A characteristic curve of maximum power point. 】 When stored in the storage battery, night illumination, when it comes to the set value, solar panels open circuit voltage is 4. Around 5 v, charge and discharge controller automatically detects the voltage value of the braking instruction, battery discharge lamp holder. Battery discharge 8. Issue braking instruction after 5 hours, charge and discharge controller, storage battery discharge end.
