3.Usage and Applications of Poly Cells

Solar cells are often electrically connected and encapsulated as a module.

Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage.

Connecting cells in parallel will yield a higher current;our solar cells have passed IEC Certification.

With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

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: Hey guys :)Well I'm in the middle of doing my PSHCE coursework on sustainable energy, focusing on solar panels. I just wanted to ask you what your opinions are of them? Are they really worth it? Are they sustainable? Will they reduce our energy bills? Those sort of questions :)If you are interested in installing solar panels, please mention that, as it would be great! There's lots of information about them on this site ----
I have a boat in a sunny place and four 80 watt panels. These will run my fridge Tv and a few LED's. I still have to run my engine for hot water and washing machine. My Batteries only last a few years and are a real pain. I go on the mains when I can to get the batteries topped up. The panels are ok if there is nothing else, they are not the answer to the future of energy supply. There is also the moral aspect of the feed in tariff. For the rich to load their electricity bill onto the less well off is not acceptable and those panels on the roof tell all your neighbors that you are doing it. That will show a greedy selfish attitude. If they are any good why don't the power companies buy them and save buying coal?
Q: K i'm almost ready to give up! I've bought every kind of pv I can think of, and I can see this technology will not be affordable in my lifetime.I conserve all I can (so far as to handwashing my laundry etc) I'm not rich, but I'm saving for a solar pv with decent amperage. I love tinkering with things if I see the point.All the cells i've seen are very weak. What PV would you buy? (all I need is to power my computer from a deep cycle 2 volt battery connected to an inverter)God Bless You
If powering a PC is your only goal, consider replacing the power supply in your PC with one that runs off native 2 volts (like the kind intended for RV's). Then you can avoid the 30% loss of energy in a cheap inverter.
Q: My home uses an average of 2400 kW per month (28,800 per year.) How much can I expect it to cost to install solar panels of this amount? (It is not my intention to go off of the electric company's grid. I would like to generate what I can / possibly sell back extra power)What quot;hiddencosts are there? What is the average life of them?What is the quot;best(cost effective and green) solution / approach?(BTW.... I am in southern LA if that makes a difference)Best answer will go to clear answer WITH links/resources to back it up!)THANKS A MILLION!!! I hope you have a safe and happy holiday season!!!
solar panels are expensive and you probably wont life long enough to recup the cost. last week the times quoted ?5000 to install, a potential saving of ?200 per year and 00 years to recoup. based on 400 hrs of sunshine. (uk) factor in your sunshine state hrs and you may just benefit.
Q: Can solar panels be used for powering outdoor lighting?
Yes, solar panels can be used to power outdoor lighting. Solar panels convert sunlight into electricity, which can be stored in batteries and used to power outdoor lights during nighttime. This allows for cost-effective and environmentally friendly outdoor lighting solutions.
Q: I know that the Solar panels store the power from the sun in the daytime, where does that stored energy go from there? Is it stored in the batteries? And how would you keep the batteries topped up if you had no Electric? by a generator? interested in solar panels for abroad, but need more info.
Solar panels do not store power. Solar panels convert sunlight into electricity. To store power you need batteries. The usual type of batteries used are lead-acid deep discharge( similar to car batteries). The batteries are charged up during the time the sun is out. However, as a backup you could also have a generator handy to provide power for times when the sun did not shine enough to keep the batteries charged up.
Q: Installing solar panels requires a big initial investment. Before I make this investment I want to check to see if the money I will save by installing solar panels will actually pay for this investment, in the long run. To calculate my savings, we should consider the area (square feet) I currently have available to install solar panels. Look at the available sunlight and its intensity in my state each month of the year. Based on this data estimate how much energy my solar panel will generate. Then compare that with how much energy (kWh) I currently consume based on my electricity bill.
Your school spend $0,000 per month or per year?? Photovoltaic (Solar Panel) panels have a really large initial capital investment. If you live in a location (e.g. West Coast Desert, SoCal) where there are many sunny days so you might be able to break even quicker. Also note ,there are state and federal grants that can help ease the capital cost. Energy demand keeps going up so expect our current rates to double. People who have alternative forms like wind and solar will have the advantage when this time comes. Just think of when the US had it's oil crisis in summer of 2008, people with small efficient vehicles such as Prius's didn't feel the price increase like the people who bought cheaper large SUV's.
Q: Solar panel for battary charging
What you are stating is that the battery you have will operate the UPS for about 2 hours before it is drained past the point of no return (technically 2.82 hours, but that would be a dead battery - most well-designed UPS systems cut off when the battery gets below about a 30% charge so that battery is not damaged. Lead-Acid batteries have about a 0%/month self-discharge rate if there is no load connected. The very best systems are as low as 3%, the worst are over 20% - and all at a 'normal' temperature. So, you will need a maintenance charger of about ten (0) watts or so - amp will be more than enough. And about any solar panel will handle that much with the proper charging connection.
Q: Are there different types of solar panels?
Yes, there are different types of solar panels. The most commonly used types include monocrystalline, polycrystalline, and thin-film solar panels. Each type has its own advantages and disadvantages in terms of efficiency, cost, and appearance.
Q: if i was to put a solar panel (sp) just outside of the earths atmosphere ans another solar panel (sp2) 0km away towards the sun. which one would generate more power (sp or sp2)? and how much more? is there a ratio to work out the power output and distance from the sun? would the 0km distance between the panels make a large difference in power output?many thanks in advance
Given identical panels the one closer to the sun would generate more power, but a difference of only 0 km at 93 million miles, the difference would be very small. Light intensity is inversly perportional to the square of the distance from the source.
