Solar street lights and ordinary street lights are two different lighting equipment. They differ in terms of energy source, environmental protection, operating cost and reliability.
First of all, the energy source of solar street lights is solar energy, which is converted into electrical energy through solar panels and stored for use by the street lights. Ordinary street lights must be connected to the electrical grid and rely on a traditional power supply.
Secondly, solar street lights are very environmentally friendly. Solar energy is a renewable energy source. The use of solar street lights can reduce dependence on traditional energy and reduce the consumption of fossil fuels, thereby reducing greenhouse gas emissions and being more environmentally friendly. Ordinary street lights consumeuse a lot of electricity and produce pollutants such as carbon dioxide.
Third, solar street lights have lower operating costs. Solar street lights do not need to be connected to the electricity grid and do not need to pay electricity bills. They only need to maintain the solar panels and replace the batteries and other components. Ordinary street lighting requires payment of electricity bills and maintenance of power grid equipment, leading to higher operating costs.
Finally, solar street lights have great reliability. Solar street lights store electricity via solar panels during the day and are powered by batteries at night. They are not affected by power supply interruptions and can ensure the normal operation of street lights. Ordinary street lights are susceptible to intepower supply interruptions. Once the electricity is cut off, the street lights will not work properly.
In summary, there are differences between solar street lights and ordinary street lights in terms of energy source, environmental protection, operating cost and reliability. Solar street lights have the advantages of renewable energy, environmental protection, low operating costs and high reliability, and are the development direction of lighting equipment in the future.
The installation price of photovoltaic solar panels varies depending on the size of the project. Generally, the quotation for 3-5 kW home system is 8-10 yuan/w. The distributed price of several hundred kW is 7-8 yuan/w. Dozens of mwd
Large power station projects generally cost around 6 yuan.
The cost of the components is approx.iron 3.8-4 yuan/w; the cost of the inverter is about 0.7-1 yuan/w; the cost of support is generally 0.4-0.6 yuan/w; other materials are generally 0.5 yuan/w; w ; Labor and construction costs are generally determined according to the construction period and project and are basically between 0.4 and 1 yuan.
