a few years ago because of solar technology is not yet mature, manufacturing cost is high, and not the manufacturer of solar street lamps, the overall market competition is not large, lead to sell the price is very high, solar street lamps lights, of course, the profit is very high. With the development of the country's new rural construction projects, solar road lights up, it's sales is also more and more high. Under the stimulus of profit and sales, therefore, a lot of capital inflow market solar street lamps, just a few short years the number of street lamp manufacturers on the market for a few times more than before. But then is the market competition is more and more big, plus solar technology mature, make the solar street light prices tend to be a reasonable level. But with the increasing of the market competition, the profit is more and more low, a lot of small mill type manufacturer in order to obtain more profits and more customers, by adopting. V system voltage producing solar street lamp, low-cost sales, seriously disturbed the normal competition in the market environment and the public praise in the industry. Today under the small make up take you to understand. V system voltage of solar street light inside.
a, lamp posts,
use cold galvanizing, low wall thickness, moreover m solar lamp posts using secondary rod production. This kind of lamp posts anticorrosive performance is very poor, scraping the strong typhoon will even appear when light pole fracture phenomenon, serious damage to people's safety. Such light pole production costs less than the standard hot galvanizing conical rod production half the price!
2, solar lithium battery
solar lithium battery. V system voltage, low production cost, but the voltage is unstable and the service life are often only for a year, the overall lighting effect also is very poor. Such solar power lithium battery production price is about half of the normal system voltage lithium battery price.
. V system voltage faults have a lot of solar street lamps, the key is that it's only half the normal service life. The overall use brightness is not good. Its only advantage is perhaps it is the price of normal V system voltage half the price of solar street lamps. So to be cautious with your brother. V system voltage of the solar street lamp, if your brother don't care about life and light effect, that you can use this kind of system voltage of solar street light.
