Q:What is the pollution of solar cells?
Now we know the battery is mainly solar cells, chemical batteries, thermocouple batteries, fuel cells, atomic batteries, chemical batteries can be divided into V batteries, batteries, batteries, alkaline batteries, micro batteries, we are common The main battery,
Q:Whether the solar cell is light can produce electricity
A solar cell is a device that converts light energy directly into electrical energy by photoelectric effects or photochemical effects.
Q:Can somebody list some of the materials used for making solar cells?
The basic component of a solar cell is pure silicon, which is not pure in its natural state.
Q:Is the solar cells factory in China good and trustworthy?
5 years ago, I vistied a solar cell factory based in Inner Mongolia, and I was quite impressed by their professionalism, which gave me more confidence that they are better than we thought.
Q:Can the 156x156mm high efficiency single crystal cells assembly function better compared to the traditional one?
Yes, according to our research and development, we have statistics to show that the 156x156mm high efficiency single crystal cells assembly does function better compared to the traditional one.
Q:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
We seldom see poly solar cell with the size of 152, because that is not really good to use.
Q:How's the feedback of using 260 watt photovoltaic solar panel? Anybody ever used that?
The one I am using is up to 19% efficiency. It can be used for 24V home power generation system or grid connected.
Q:How does the photovoltaic cells work?
Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity.
Q:What is the solar cell?
The type of solar cells can be divided according to the materials used: silicon solar cells, solar cells and organic semiconductor system of solar cells.
Q:On the parallel connection of solar cells
As for the solar cells in the string, parallel combination is Causing the damage of the battery pack, I think it is first necessary to make sure that the "combined" solar cells should have the same characteristics, and that the various parameters between them should be the same or similar, at least several major parameters must be the same, to achieve these Conditions can be combined after the combination; if the series combination in the use of a group of solar cells damaged and broken, then the other groups will not power the power supply equipment, because the entire line has been in the open state,
