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.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.

Dozens of these PV cells are packaged together into solar modules, which in turn are packaged into solar panels that are mounted on a rooftop and arranged to maximize their hours of exposure to direct sunlight. Because the electricity generated by all those solar cells is direct current (DC), it is then sent to an inverter that transforms the power into the same alternating current (AC) used by the appliances in your home and the local utility electricity distribution grid. Increasingly, these inverters are getting "smart," providing data monitoring for solar installation performance and other grid integration services.

Q:Green issues aside, are solar panels worth it, monetarily speaking?I don't mean that my house might be worth more or any of that. All I am asking is this: if I invest in a set of solar panels, will the cost be paid back to me over time? If so, how long will it takegt;Take into account the following:. Currently I pay the electric company around $00 per month2. I use around 400 kilowats of energy per monthI realize that exact numbers are hard to come by, but any opinions are welcome.: There are several factors to consider when looking into solar power for your house. If you want to replace your use of utility electricity with solar power for say a 500 - 2000 square foot home then the system will cost you at least $30000 - $50000 to install. You will also have the maintenance issue of your storage batteries, panels, and inverter which will eventually wear out over time. So lets say we have an optimistic price of $30000 for a whole house system (this would be really cheap), dividing this by your yearly consumption would give you the amount of years it would take for the expenditure to pay for itself (not counting maintenance which could be costly). The payoff would be about 25 years, so all things remaining equal, I would say that it is a bad investment. Solar panels as they are manufactured today do not have a very long life span. They will greatly decrease in efficiency after several years and will most likely need to be replaced in 0 years. The panels themselves are the greatest expense. You could problably find better ways to make/save more money by investing $30000 - $50000 somewhere else IMHO. Solar technology is still not at the point where it is profitable in the sense you are thinking about. Unless of course, there are huge tax incentives for you or large rebate programs through your local utility, but you would have to do the math on that as well. If you are thinking small as in a couple panels to supplement your utility electric, the above still applies as well. In fact will it take longer to recoup the cost of a smaller setup. Hope this helps!

Q:I would like to know if I had a mobile kitchen could I power it from solar panels mounted atop the vehicle (truck).(to power electric kitchen equipment, i.e. stove, deep fryer.), instead of propane…could I possibly connect the solar panels to a battery to save my generated electricity? If solar panels would not be enough power could a small windmill suffice…?: The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^

Q:We are looking in to buy solar panels for our house. The payment has to be around or under $4000. Our house is a 4 bedroom and 3 bath 2-story house. (Around 2500 sq. ft.) Where can we get the solar panels? Also: Will it heat our water? When we get the solar panels, what direction do they have to be facing?: The crisis is that it's so high priced to have mounted and as you assert it's going to take decades earlier than you honestly begin saving above what the install rate used to be, I for my part might now not cross forward and make that kind of funding, it might be extra lucrative to hold the cash in a constructing society, get the curiosity from it and use that to pay to your electrical energy however the important factor that I have towards sun Panels is that until you keep in that condo for a minimum of twenty 5 years you'll now not succeed in the factor in which you're saving and to capitalise on it you might need to keep there for decades extra, so you'll now not have the choice of relocating condo with out wasting your funding and on the second having sun panels does now not develop the significance of the estate, it's only a well promoting factor, while you purchase your new condo, you might commonly need to begin everywhere once more after which given that of the years will on no account reside lengthy ample to obtain any improvement from it.

Q:How much would it cost to make an average size house be able to depend on solar panels for all of its power?How many solar panels would you need and wear would you put them? Would the roof be large enough to support the panels needed?Do solar panels work well in higher latitudes like northern USA or southern Canada? Can you power your house for the whole year if you live in these environments? What kind of maintenance do solar panels require?: In the US, the average electricity consumption for a house is 958 kwh per month which is 32 kwh per day for a 30 day month. Once you get to New York City, the number of hours of usable sunlight drops to four hours per day so using six hours a day as a guideline and the fact that inverters tend to be 65% efficient, you wind up requiring 8.205 kw of solar panels which at $5 a watt amounts to $4,205 not including the inverter. Your first task would be to reduce your energy use. Keep in mind that the effective cost of solar power in 2007 was 38 cents per kwh. Without government incentives, you wind up paying more for your electricity than had you just bought it from the grid.

Q:Can solar panels be used for charging electric bicycles?: Yes, solar panels can be used to charge electric bicycles. Solar panels convert sunlight into electricity, which can then be used to charge the batteries of electric bicycles. This eco-friendly and sustainable method of charging allows for convenient and cost-effective transportation.

Q:How do solar panels impact the electric bill?: Solar panels can significantly reduce or even eliminate the electric bill. By generating electricity from sunlight, solar panels can offset the amount of power needed from the grid. This means that homeowners or businesses with solar panels can consume less electricity from the utility company, resulting in lower energy bills. In some cases, excess solar energy can be exported back to the grid, earning credits that further reduce the electric bill.

Q:Can solar panels be installed on golf courses?: Yes, solar panels can be installed on golf courses. In fact, golf courses provide ample open space and sunlight exposure, making them suitable for solar panel installations.

Q:Can solar panels be used in areas with high levels of snowfall?: Yes, solar panels can be used in areas with high levels of snowfall. However, the performance and efficiency of the panels may be affected during snowy conditions. Regular snow removal or tilted mounting angles can help maximize their effectiveness in such areas.

Q:How do solar panels impact the aesthetics of a building?: Solar panels can impact the aesthetics of a building in both positive and negative ways. On one hand, when designed and installed properly, solar panels can enhance the overall appearance of a building by giving it a modern and eco-friendly look. Additionally, the sleek and reflective surface of solar panels can add a visually appealing element to the design. On the other hand, some people may find the presence of solar panels on a building to be visually unappealing, especially if they disrupt the architectural harmony or contrast with the surrounding environment. Ultimately, the impact of solar panels on a building's aesthetics is subjective and depends on individual preferences and the integration of the panels into the overall design.

Q:I am planning to buy some solar panels for my cabin and i want to be able to store the electricity. what kind of batteries should i get? i will be running simple things like a tv and radio. where can i buy these batteries? where should i look for the best batteries?: Deep cycle, Golf Cart Batteries. You can get them at a battery store.
