PV: the battery to the battery charge problem
- I use the BUCK circuit, controlled by the microcontroller, the circuit is not too difficult, are ready, but the understanding of BUCK problems. See a lot of books are written on the battery can be constant pressure charging, feeling can not understand. Now I think they are probably wrong, the voltage across the battery in the BUCK circuit is out of control.s
What information can I get from the Internet about the solar cell modules? Such as what it is? How it is made?
- A solar cell module has a chamber and includes a solar cell device, a gel /fluid, and a light-focusing unit. The solar cell modules are basically a group of solar cells used a specific function.s
How to manufacture solar cells?
- It's a bit difficult to describe.s
Can anybody tell me how to make a solar cell at home?
- To make a solar cell at home, you need to have things like these : Thin copper sheeting,
Metal shears an emery cloth, etc.s
Solar cell life for several years

What are the advantages of monocrystalline silicon and polycrystalline silicon in solar power?
- and the production process of polysilicon can be achieved by casting method and direct solidification method. Grain size of the grain size of centimeters;  due to nearly a decade of monocrystalline silicon technology research and development soon, in which the process is also used in the production of polycrystalline silicon cells, such as the choice of corrosion emission junction, back surface field, , Surface and body passivation, fine metal gate electrode, the use of screen printing technology can reduce the width of the gate electrode to 50 microns, the height of 15 microns or more, rapid thermal annealing technology for polysilicon production can greatly shorten the process time,s
What is the best way to deal with surplus solar cells abandoned after burning?
- This is a very commonly mentioned topic related to environmental protection, because the abandoned solar cells have battery surplus could be very bad for our environment. Scientiests are dicussing ways to deal with that but there is still not a good solution.s
I have a turnkey solar power project starting in 6 months, now we are searching the market in south China to find the best solar cells manufacturers. Any professional suggestion or recommendation?
- In south China, you will have more resources than in north China, because there are many solar cell factories over there, which means you get to have more choice to select from.s
