Reasons for the different quotations of solar street lights

The origin of the price difference: LED lamps, photovoltaic panels, batteries. 1. The customer asks 'How much is the 6-meter solar street light?' Some companies offer 1,000 and some companies offer 2,000. Reason: There is no consistent parameter requirement. 2. The customer asks 'How much is the 6-meter solar street light, 30W light source, 100W photovoltaic panel, and 100ah battery?' Some companies offer 1200 and some companies offer 1800. Reason: It's cutting corners to quote a low price! Although the parameters are constrained, in order to compete for affairs, some companies will deliver according to 20W-70W-65ah or other specifications. 3. The customer asks 'How much is the 6-meter solar street light, 150W light source, 200W photovoltaic panel, and 300ah battery?' Such a street light will not be quoted by regular companies. After all, it must be a small business, but it will be a big profit. This parameter equipment is obviously high and unreasonable. It leaves a lot of room for imagination and profitability for companies that are good at cutting corners. There are chaos in the market of solar street lights, 80% of the products are substandard, and they are not manufactured in accordance with the contract specifications. The main reason is that the power of LED lamps, the wattage of photovoltaic panels, and the capacity of storage batteries cannot be detected by ordinary customers, which makes cutting corners and materials, and price competition is different.
