product description

 

Currently, polysilicon is commonly used for the conducting gate materials in semiconductor devices such asMOSFETs; however, it has potential for large-scale photovoltaic devices.The abundance, stability, and low toxicity of silicon, combined with the low cost of polysilicon relative to single crystals makes this variety of material attractive for photovoltaic production. Grain size has been shown to have an effect on the efficiency of polycrystalline solar cells. Solar cell efficiency increases with grain size. This effect is due to reduced recombination in the solar cell. Recombination, which is a limiting factor for current in a solar cell, occurs more prevalently at grain boundaries,

Q:hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:Can solar panels be used for powering a wastewater treatment plant?
Yes, solar panels can be used to power a wastewater treatment plant. Solar energy can be harnessed and converted into electricity, making it a sustainable and environmentally friendly option for powering such facilities. The generated electricity can be utilized to operate various equipment and processes involved in wastewater treatment, reducing dependency on traditional power sources and minimizing the carbon footprint of the plant.
Q:in a solar panel, i know that the electrons are knocked loose and used as energy, what happens to the protons?
silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as you
Q:Have a 20V 40W solar panel and it is attach to two backup batteries. Just want to know know how many watt of inverter do I need?
It depends on what you want to run from the panel. A 20W inverter might last a long time, but would not run much. A 00W inverter might run down your batteries in a few hours. It might help if you posted how much capacity (Volts, Amp-Hours) the batteries have.
Q:I was watching an idiot abroad, and I saw a family that lived in tent like huts, with no plumbing. And they had a solar panel, now if they can afford it, I know I can. Where do you get cheap ones?
you okorder . all you have to do is watch the video.
Q:Do solar panels require regular inspections?
Yes, solar panels do require regular inspections to ensure optimal performance and identify any potential issues such as damage, debris, or faulty connections. Regular inspections can help in maintaining the efficiency and longevity of the solar panels.
Q:Can solar panels work at night?
No, solar panels do not work at night as they rely on sunlight to generate electricity.
Q:I have a 2V .5W solar panel and I want to get a battery that can be charged by the solar panel that can then be used to power a 2V .5W fan. Ideally I want all the components to be connected and able to run without interaction. I have very little knowledge in regards to this field which is why I have come to yahoo answers. Any help would be greatly appreciated.
There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:Any opinion on harbor freight solar panels ?
I bought my first set 8 years age and the 45 watt set finally gave up the ghost last week. I have another 45 watt set 3 years old and has maintained 4 2 v deep cell batteries at 3.5 to 3.8 volts for the last 3 years. I have them on my cabin and use them mainly for lights and TV. but with my 2000-4000 watt inverter runs the microwave nicely.
Q:How much would it cost (approximately) to convert my home (3 bed. 2 bath) to a green home that is run entirely upon solar panels on my roof? From the panels through installation does anyone know a price break down?
the st element to comprehend is that there is no longer something complicated some photograph voltaic panel. this is not something greater beneficial than a selection of of photograph voltaic or PV cells on a board this is suited for the main spectacular area of your abode, generally on the roof. There are publications obtainable that coach you the thank you to construct a photo voltaic panel and a windmill for basically $a hundred and fifty, and it’s truly difficulty-free to make. appropriate of all, you may save 70% or greater on your potential invoice, including as much as hundreds of dollars each and each 2 months in reductions. I reviewed the two unfastened publications and paid publications and have arise with our ideal to construct your individual photograph voltaic panels.
