Information

When we drive on the highway, we can often see billboards, which are well-lit during the day and can be seen clearly, but are still displayed when there is no light at night. Some highways pass through remote mountainous areas, and there is no alternating current, so what does it provide electricity through? It turned out that he charged the solar panel during the day, stored it in the battery, and provided power to the billboard lights at night. A complete set of solar panels consists of several parts

One: solar photovoltaic panels
We can calculate how many W solar photovoltaic panels need to be installed by calculating the power and voltage of the billboard, the daily lighting time, and estimating a few rainy days. Usually the power of the solar panel is relatively large, so we need to match the photovoltaic panel bracket. One is to fix the solar panel, and the other is to position the solar panel too high to prevent it from being blocked by grass or branches.
 Two: battery
The batteries that match the billboard usually use lead-acid batteries or gel batteries, because the cost of lithium batteries is too high.
Three: solar charge controller
By installing a solar charge controller between the solar photovoltaic panel and the battery, the battery is protected, and it has the functions of light control and time control at the same time, so that the solar billboard lights up in the dark every day and turns off the lights according to the set time.
