product description
Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
Multiple solar cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic panel or solar photovoltaic module. Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor wafers. Solar cells are usually connected in series and parallel circuits or series in modules, creating an additive voltage. Connecting cells in parallel yields a higher current; however, problems such as shadow effects can shut down the weaker (less illuminated) parallel string (a number of series
Feature
The modules use high-quality imported polycrystalline or Polycrystalline solar panel;
Enclosed by high-rigidity tempered glass, with excellent light transmittance and output performance;
Surface treated with reflection-reducing process, increasing the light absorption.
Back sealed with anti-aging EVA, resistant from moisture and corrosion.
The efficiency of our Polycrystalline solar cell is over 17%, and polycrystalline panel is over 16%. We stipulate, the allowance of each panel’s rated power has to be positive. Each panel is strictly tested before leaving the factory.
Our solar panel is designed with a lifetime of 25 years, and guaranteed that the power decline less than 10% within 10 years, and 20% within 20 years.

- Q:I have a panel that quot;deep breatheproduces at 4% efficiency, what can it power, It's about 4ft by 2ft
- Area is 4' * 2' * (0.3048m/ft)^2 = 0.743m^2. Incoming solar (assuming optimally oriented panel) averages about kW/m^2, so 743W max gross. 4% efficiency yields 300W. Most panels are about 0% - 5% efficient, which is about W. In either case, figure about /2 the theoretical efficiency for about 2 hrs per day. so, you can run something from 50 to 50W about 2hrs per day. Too small for any appliance except maybe a laptop or light bulb. Panels typically make about 2V, not enough to run household stuff anyway. Normally panels are used to charge batteries, then an inverter takes power from the battery to run your appliances. Good luck!
- Q:What is the most efficient solar panel, how many would we need to power the United States, and how much land would it take?
- well the main problem is that the the solar panels are ineffecent due to their 5 lays(that is what i hunrd they are useing in Gemrnay). Also if i remember right we are at a 20% conversion rate on solor panels. their is 2 problems with solar panels. the weather they drom in effeceny everytime the a cloud get in the way of the sun. what are u doing to do when it gets dusk time? tho neucler power is a good idea. it is only good for the Base load not for the peek power times... IE; Quiting time when everyone gets home and flips on the AC. The best thing really would be Geothormal, nucluer, wind and some solor. but that is for the west out word.. the south is still SOL. So they would need bio fules, better coal plants and fuel cells. (witch is where i am going to start working on here soon )
- Q:We've been considering solar panels for a while now, and we'd like to know a little more about them. Please answer to the best of your knowledge. Thanks.
- Solar Panels are a very good choice for our economy today. We can save thousands of dollars a year of electric bills. But they are not practical to buy because these cost thousands of dollars. For the brand new solar panels and installation, it cost more than $20,000 which is not good. They also offer buy now pay later option but it is not good either because it puts you in debt. The solution is, why not do it yourself. There are do-it-yourself guides that shows you step-by-step on how to make solar panels. They are very cheap too. All-in-all, it'll cost you less than $200. But be careful, you might find a DIY solar panel guide are not advisable to someone who don't have experience on them. There is one DIY solar panel guide that I can recommend. It is cheap and it doesnt require you to be a handyman to do it. Check out the site below. If you want to know more about solar panels, check some reviews about it. I included some sites as well.
- Q:Can solar panels be used for charging electric vehicles?
- Yes, solar panels can be used to charge electric vehicles.
- Q:Ok, so I've been having much success with the joule thief circuit and a LED, but i tried hooking it up to a small solar panel that can put out 2.5v on it's own, and can light up a white LED dimly by it self to the joule thief and it will not work ....my question is why? I already trouble shooted it, the circuit is not the problem, is it the amount of amps the small solar panel is capable of? not enough?
- Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
- Q:What is the impact of roof orientation on solar panels' performance?
- The impact of roof orientation on solar panels' performance is significant. The orientation of the roof determines the amount of sunlight the panels receive throughout the day, affecting their efficiency and energy output. Ideally, solar panels should be installed facing south to maximize exposure to sunlight. East and west-facing orientations can still generate energy but at reduced levels. North-facing roofs receive the least amount of sunlight and would result in the lowest solar panel performance.
- Q:Can solar panels be used in areas with limited access to electricity?
- Yes, solar panels can be used in areas with limited access to electricity. Solar panels convert sunlight into electricity, making them a suitable and sustainable solution for generating power in remote locations or areas without a reliable electricity grid. They can provide clean and renewable energy, helping to meet the electricity needs of communities with limited access to traditional power sources.
- Q:. Do they scratch easily? How do I remove snow from them without scratching them?2. What does the upkeep of many solar panels consist of? I want to have my electricity completely off of the grid.3. Are all solar panels made from the same material, regardless of size?
- anythign can be scratched/ruined/altered if not tended to properly.... remove the first biggest layer of snow and leave a lil under to try to see first if it melts away on its own (dpeendin what season of course) if not than get some luke warm water and soak the snow.... slosh it off with a rubber shovel or mop.broom whatever wont damage ur panels. anythign you take care of will last longer and take care of you.... and solar is expensive to put in and can be expensive to maintain . depends where you have most sun and depends how many resources you use, if you leave the tv on absent mindely all night and take 50 min showers or blast the heat with jsut on epathetic lil donwpour of rain instead of just BUNDLING UP like a alot of lazy *** ameicans and.or rich careless bastards of course youa re goign to be paying up and out of your asshhhhh-hooooo and nooooo there are some different materials solar panels are made of, there is a main base/core they use but im sure there are AT MOST two...the rest is either glass or plastic! depends for what you want and how many , includign size.... good luck!!!! excuse my typos
- Q:Can solar panels be used in areas with high levels of bird or bat activity?
- Yes, solar panels can be used in areas with high levels of bird or bat activity. However, certain precautions should be taken to minimize potential risks. For instance, installing bird deterrents like netting or spikes can prevent birds from nesting or perching on the panels. Similarly, incorporating specialized designs or modifications can minimize the impact on bats. By implementing these measures, solar panels can coexist with bird and bat populations while still harnessing the sun's energy efficiently.
- Q:Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?
- Only after you give an estimate of the power consumption you will have in the basement. Obviously you do not have a clue about solar panels or their usage. Suggest you find a book and start reading.
