At first glance, the price of the national wind solar street lamp is quite expensive, but in fact it is still saved on the whole. The biggest reason that affects the price of solar street lights is the wattage of street lights you choose. The larger the wattage, the higher the price. Of course, the price of circuit lights and wattage are also related, but the price jump will not be so big, because solar street lights are By collecting light energy and converting it into electrical energy, the bulb is illuminated. The larger the wattage, the higher the quality of the battery and solar panel, so the price has risen sharply. However, most of the 30w energy-saving lamps used in rural lighting are enough. In this configuration, as long as 3 years, the cost incurred will be the same as that of the circuit lights, and the cost will start to be saved. Save money and energy.
