FAQ

How to define the poly solar cells as the A Grade one?

If the poly solar cells is high module conversion efficiency, through superior manufacturing technology Guaranteed -1% to +3%, it is very possibily the A grade.

Bird droppings can significantly reduce the efficiency of solar cells. The droppings create a layer of dirt and debris on the surface of the cells, blocking sunlight from reaching the photovoltaic materials. This obstruction can result in a decrease in electricity generation and overall performance of the solar panels. Regular cleaning and maintenance are necessary to maintain optimal efficiency and prevent any long-term damage caused by bird droppings.

The efficiency of solar cells refers to the percentage of sunlight that can be converted into usable electricity. It varies depending on the type of solar cell technology used, but current commercial solar cells typically have an efficiency range of 15% to 22%. However, research and development efforts are continuously improving solar cell efficiency, with some laboratory prototypes achieving efficiencies exceeding 40%.

The amount of electricity a solar cell can generate depends on various factors such as the size and efficiency of the cell, the intensity and duration of sunlight, and the environmental conditions. On average, a standard solar cell can generate around 1 to 2 watts of electricity per square meter under optimal conditions.

Yes, solar cells can be used in electric fences. They can be used to power the fence's energizer, which delivers an electric shock to deter animals or intruders. Solar cells are efficient in converting sunlight into electricity, making them a sustainable and cost-effective solution for powering electric fences in remote locations without access to the grid.

Commonly used materials in solar cells include silicon, which is the most widely used material in photovoltaic cells, as well as thin-film materials such as cadmium telluride (CdTe), copper indium gallium selenide (CIGS), and amorphous silicon (a-Si). Other materials like perovskite and organic materials are also being researched and developed for solar cell applications.

Bird droppings can significantly impact solar cell performance by reducing the amount of sunlight reaching the surface of the cells. The droppings can act as a physical barrier, blocking sunlight and reducing the efficiency of the solar cells in converting sunlight into electricity. Additionally, the chemical composition of bird droppings can cause corrosion and damage to the surface of the cells, further degrading their performance over time. Regular cleaning and maintenance are essential to ensure optimal solar cell efficiency and prevent any long-term negative impact from bird droppings.

Yes, solar cells can be used for powering electric fences. Solar cells convert sunlight into electrical energy, which can be stored in batteries and used to power electric fences. This provides a sustainable and environmentally-friendly solution for powering fences in areas where access to grid electricity is limited or expensive.
