Q:Can the solar powered cells really work better than the normal cells?
There is no doubt that the solar powered cells work better than the normal cells, the only disadvantage is the cost of making it.
Q:Is that true that the price of solar cells will be reduced in the coming year?
There are some policy change from the central government that financial subsidies of purchasing solar cells from the government will be lowered compared to last year. This could be a big reason for the price going down.
Q:How does the solar panel produce it yourself?
 Step 5: Assemble the battery Place the titled titanium dioxide film face up on the table, drop one or two drops of electrolyte containing iodine and iodide ions on the membrane, and then press the conductive surface of the counter electrode down on the titanium dioxide film The The two pieces of glass were slightly staggered so as to use the exposed portions as the electrodes for testing. Use two clips to hold the battery, so that your solar cell is made
Q:How can I buy the solar cells wholesale ?
You can talk to the manufacurers directly and ask them to send you the quotation list based on what you need and how many solar cells you need.
Q:How is the solar cells factories working in China? Do they follow certain quality standards?
Of course, the follow the quality assurance standard, and in fact, they are as good as the solar cell factories in US.
Q:What is the window material in the solar cell? what's the effect?
The meaning of the window layer with his Chinese meaning is the same, referring to the first solar cells to accept the light.
Q:How's the feedback of using 260 watt photovoltaic solar panel? Anybody ever used that?
the 260 watt photovoltaic solar panel is widely used in the solar cell power supply plant, and my personal feedback is very positive.
Q:How long is the long cycle solar cell life?
A look at the application of the environment, if the ambient temperature is high, then in general, to 25 degrees as a benchmark, each increased by 10 degrees, life-span reduced by half;
Q:Where can I get the most accurate information about solar cells?
Don't trust whatever you search online, trust the book.
Q:Many people said the usage of solar cell can reduce the cost overall, but does anyone agree with me that it actually cost a lot to operate a solar cell system?
Yes, I agree with you in this way because it is true that operating the solar cell system cost a lot.
