Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

Q: My house uses 500 kw a month, air conditioning is the main consumer, is it possible to install solar panels in my roof to produce this amount, and aproximate cost, thanks .
I assume you mean 500 KWH (Kilowatt Hours) A good panel may produce about 00Watts. It will cover about 2SQ FT. Lets say you have a ranch style house that is 2000 SQ FT. That means if you covered your entire roof with panels, you could get about 65 panels on the roof(Not really, because you need room to get around them. Lets say practically you could get 00 panels on the roof. You could produce 00X00, or 0,000 Watts/hour (0 KW/HR)when the sun is at peak. Each hour you would produce 0 KW HR's. Lets say your area is perfect and the sun shines bright 0 hours a day, so You could potentially produce 00 KW HRS. There are losses envolved in the wiring, Battery Charger, Storage Batteries, and rectifier-controller. Maybe more realistically you could get 70 KW HRS per day. Maybe you could get 500 KWH in about 2 days. Each panel will cost about $500-$700. Panels alone will be over $50,000. The entire system installed about $00,000. This should cover your electric at least during sunny times. If you live outside of Arizona, lots of luck. Still much cheaper to ude the grid.
Q: Can solar panels be used off-grid?
Yes, solar panels can be used off-grid. Off-grid solar systems are designed to generate electricity independently from the utility grid. These systems can store excess energy in batteries for use during times when the sun is not shining or when power is needed at night. Off-grid solar panels are commonly used in remote locations, such as cabins, RVs, boats, and even in developing countries without access to reliable grid electricity.
Q: i have this usb solar panel charger i am building and the solar panel is about 2by .5quot;, so i was wondering if a led light can power it, if so will one be good or would i need more? if so how many?
Yes, shining light from a visible-light LED on a solar panel will cause the solar panel to generate electricity. There is a long-wavelength cutoff (probably in the near infrared) where photons from an infrared LED would not have sufficient energy per photon to excite the solar panel, no matter how bright the LED was. Of course the amount of electricity produced is a fraction of the power needed to power the LED. The best possible efficiency you could achieve under optimal conditions is about 30%. The typical optical power output of a single LED is around 0.3 Watt. The density of sunlight is such that the amount of sunlight falling on a 2 x .5 area perpendicular to the Sun's rays is about .3 Watts. So maybe you'd want a few LEDs, or a particularly bright LED to simulate sunlight. But you'll get something with one LED. A bright LED flashlight would work.
Q: Hi, I am very interested in solar panels and would like to know more.Can someone please give me a basic explanation of how solar panels work?Thank you
Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity.
Q: Can solar panels be used in off-grid systems?
Yes, solar panels can be used in off-grid systems. Off-grid systems are designed to operate independently from the electrical grid, and solar panels can generate electricity from sunlight, making them a reliable and sustainable source of power for off-grid applications.
Q: Can solar panels be used to power a construction site?
Yes, solar panels can be used to power a construction site. They can provide a sustainable and renewable source of energy, reducing the need for traditional fuel-based generators and minimizing carbon emissions. Solar panels can be installed on rooftops or on portable structures, providing electricity to power tools, lighting, and other equipment required on a construction site. Additionally, excess energy generated by solar panels can be stored in batteries for use during non-sunlight hours, ensuring continuous power supply.
Q: So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.
solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
Q: Can solar panels be used in areas with high levels of shade or obstruction?
Solar panels are not very efficient in areas with high levels of shade or obstruction as they rely on direct sunlight to generate electricity. However, there are certain technologies and panel designs available that can still produce energy in shaded areas to some extent, although their overall efficiency may be reduced.
Q: I am in need of solar panels and the batteries that I can store the energy in. I need to be able to run a laptop, cell phone, and LED lights from it. When I research I see all sorts of options with regards to watts, VMPs, and AMPs. I also see that I may need a controller, an inverter, and various other components. Can anyone help me through these terms and what i need to know in order to efficiently generate and store the electricity. Thanks
You can not really store electricity. a battery may seem like it, but it won't store it forever. What you can do, is let a professional installer install solar panels on your house. They will connect this to the mains electricity. If you are not using the electricity, then it will be distributed to others. You will receive money for this (or actually, you'll have to spend less yourself). So lets say you use 000 kwh a month (is alot) But the solar panels produce 500 kwh a month (is alot) Then you will only have to pay for 000-500=500 kwh, while you used 000 kwh. Solar panels are an investment, they cost much to install, but they will save you're energy bill.
Q: How much per sq inch do they cost? Will i have to worry about them blowing off during hurricane season? If the sun isnt out for a week will my power go out? Will I have to check them every week and check which ones arent working and replace them? Is there anyway for them to be damaged by acid rain or any type of erosion like hail? When do I have to replace them? How do I dispose of old ones (like recycling)? What is smarter and more economical having few big panels or many small ones? I know I have alot of questions but I want a good detailed answer.
