solar street light: money-saving secrets for town and country lighting

In the past, the electricity bill for night lighting in urban and rural areas was a lot of money, but now technology has changed life - solar street light has become the secret of saving money in urban and rural lighting. Why do you say that - install solar street lights and the sun pays your electricity bills. This is to understand the working principle of solar street light: solar street light is made of solar cells using the principle of photovoltaic effect. During the day, solar panels receive solar radiation energy and convert it into electrical energy output, which is stored in the battery through the charge and discharge controller. In the middle of the night, when the illuminance gradually decreases to about 10lux, the open circuit voltage of the solar panel is about 4.5V. The charge and discharge controller detects this voltage value and acts, and the battery discharges the lamp head. At this time, the solar street light starts lighting, and you can decide how long the lighting lasts. Solar street light does not need to pay electricity bills, I believe this is one of the reasons that attracts most people. However, the place where solar street light can save you money is more than just this one. The installation of solar street light is simple, and customers who have installed mains know that the workload of trenching and burying is very large. At the same time, after several years of use, the line is aging, and the maintenance and replacement cost is not small. The solar street light does not need to ditch and bury the wire, and the amount of work is relatively small. Just install a cement base and fix it with stainless steel screws. Installation is simple and virtually maintenance-free. The later cost is small, saving a lot of maintenance costs. In addition, solar street light is a clean and renewable energy source, which not only saves electricity, but also reduces carbon dioxide emissions. Now that the whole country is calling for energy saving and emission reduction, how can solar street light be missing? According to data, each 250-watt high-pressure sodium lamp will produce 1,290 kilograms of carbon dioxide within a year, so after all 60 million street lamps are changed to solar street lights, 77.4 million tons of carbon dioxide will be reduced. After changing to solar energy, it not only saves electricity bills, but also saves the cost of carbon dioxide reduction. The abatement cost per ton of CO2 is $345-404. A reduction of 77.4 million tons of CO2 equates to a savings of $31 billion in CO2 abatement costs. solar street light: The secret to saving money in town and country lighting. With the continuous maturity of solar street light technology, the price of solar street light is also much cheaper, and city circuit lights have been gradually replaced. Solar street lights are being installed on both urban and rural roads, and even many farmhouses have installed them. Going on a small solar street light can save energy and save money!
