How much is the solar street lamp?


As a street lamp manufacturer, many times we received advice from customers. How much is your home solar street lamp? When we ask customers for details, a lot of people don't know the details, the customer just thinks it's beautiful, or the lighting effect is good at night. For this kinds customers, as a responsible manufacturer, we can not offer you the price.


The solar street lamp is a whole system, which includes the panel, led light source, battery, controller and light pole.Today we will introduce the impact of the price of solar street lamps from the panel.


There are three categories of solar photovoltaic panels, Monocrystalline silicon solar panels, polysilicon silicons solar cells polysilicon solar cells and amorphous silicon solar cells (thin-film solar cells).

solar panel
Monocrystalline silicon solar photoelectric conversion efficiency is about 17%, the highest can reach 24%, this is the photoelectric conversion efficiency is highest in all types of solar cells, but the production cost is relatively high, its durable, service life of up to 25 years.


The production of polysilicon solar cell is similar to that of monocrystalline silicon solar cells, but the efficiency of photoelectric conversion is much lower, and its photoelectric conversion efficiency is about 15%.In terms of making costs, it's cheaper than Monocrystalline silicon solar cells. So now it is the most widely used panels.


Amorphous silicon solar cell (thin-film solar cell)


Amorphous silicon solar cell is a new kind of thin film type solar cell in 1976, it has to do with the method of making the monocrystalline silicon and polycrystalline silicon solar cell is completely different, its main advantage is can also generate electricity in low light conditions.But amorphous silicon solar cell is the main problems the photoelectric conversion efficiency is low, the current international advanced level of about 10%, and is not stable, with the extension of time, the attenuation of conversion efficiency. The current application is not widespread.


Different types of panels, light conversion efficiency is different. But the same kind of panels, the quality of is different,the service life and light conversion efficiency is also different,the cell is the main part of panels , the quality of the cell is divided into four categories, A, B, C, D.The better the grade, the longer the life span, the higher the efficiency of light conversion and the higher the price.


A lot of times we hear customers asking about 100W panels. Why is the price so different?The first thing we want to do is distinguish between monocrystalline silicon or polycrystalline silicon solar cell, and then the level of the cell that is used for the panel.Therefore, select the right products according to the price quality.
