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:how to build a solar panel?
Can you show us how to build a solar panel ?
Q:how much power do i need from my solar panels?
Very simple. Look at your bills from the past year and calculate how much power you used and see what you need to cover that usage. How are we supposed to know how much power you use? Maybe you live in a bdrm trailer or a 6000 sg ft house with 20 kids. Oh and remember a few things. There is more to ' going off the grid ' than just solar panels. When the panels work depends a lot on your climate. They kind of suck on cloudy days or if you live in the artic with 6 months of darkness.Also , you need an area for the (not so cheap) storage batteries. Learn to live by cooking with gas or wood as hydro is limited , so is heat. How do you plan on heating your home /water/ refrigerators and freezers? Off the grid means a lot of compromise. Even the amount of time you can spend on the computer asking these questions. You may be limited to no more than hr per day. Off the grid also includes removing any electronic influence. No cell phones , tv (cable/sat) internet. Grow your own food and live off the land. The amount of solar panels you would need to maintain even a current lifestyle as most of us know it would probably require at least /2 acre and the cost would take at least 5-25 yrs to recover. You really need to spend more time into looking at what the cost versus return is. Like I said before. Look at what you use and see what it takes to get that from your panels. You will be shocked. Currently the panels are very good. But they cannot produce what the average home needs per day every day, they are support systems. Much like a fire place. Now they are nice to have and are very efficient. 50 yrs ago you used to toss in 2-3' logs about 6 around into the only heat source in your home. A fireplace. And it sucked more cold air into the house than the heat it produced. History has a way of repeating itself. This stuff was out almost a decade ago, they just didn`t have batteries then
Q:How to make electricity from the sun without using solar panels?
There are a couple other methods under development. One uses a fan inside a cooling tower and a large area covered with black tarps. The heated air can only escape through the cooling tower in the center of the site. The air movement turns the fan blades that spin a generator. Another solar generator uses mirrors that track the sun and focus their energy on a large pipe. I don't recall the contents of the pipe, but the superheated material is used to boil water generating steam to spin a turbine/generator. Neither of these are small scale projects, and are probably far more expensive than what you're looking for.
Q:Solar Power...........?
The guy put solar panels on a Datsun.
Q:Solar panel help please?
Solar water heating is low technology. There are do it your self plans for it all over the internet. There is no electricity involved. Simply laying a garden hose on the ground in the hot Sun can heat the water to really high temperatures. Just have a shutoff nozzle on the hose, turn on the tap and open the nozzle until water comes out and then close the nozzle at the end of the hose. Let the hose full of water sit in the sun for an hour or so and then open the nozzle and feel how hot the water is that comes out. Be careful, because it can be so hot you can get a burn! When the gallon or so that can fit in the hose has all come out and is replaced by other water from the tap, it will feel cold again. Close the nozzle and wait another hour to heat it up again. A solar hot water heater is just a very long coil of pipe in the Sun, maybe with a pump to slowly circulate water from a holding tank so you can make and store more hot water that fits in the hose. Solar electric power is completely different. It uses semiconductor devices called solar cells to make electricity directly from light. Many of solar cells are usually arranged into large panels to make larger amounts of power. In electricity, Watts = Volts * Amps. Battery capacity is usually measured in Amp-hours. Small solar panels are often designed to produce electricity at 2 volts. A 60 Watt, 2 volt panel makes 5 Amps of electric current, because 2*5=60. So if you use it to charge a 2 volt battery with a capacity of 5 Amp-hours it will take hour to charge. A 0 Amp-hour battery would take 2 hours to charge with the same panel.
Q:How does solar panels work?
Solar panels are built with light-sensitive panels. These panels soak up the energy from the sun's light. This energy is changed to electric power. This power is stored in batteries to use whenever / wherever it is needed.
Q:Infra-red solar panels?
They are actually working on building photovoltaic panels (Photovoltaic is actually the correct term for sunlight--electricity. Ordinary solar panels are those that use sunlight to heat water) that harness a larger range of wavelengths. From what I can gather the problem is either finding a material that absorbs more wavelengths, or finding a way to get multiple materials to coexist in a single panel. This situation will no doubt improve over time as new things like Nanotechnology give us the ability to create much more complex substances designed at the molecular level for light capture. Panels that can harness a wider range of the spectrum do exist, but the technology is in its infancy, and therefore expensive and not widely known. This isn't too surprising when you consider that Photovoltaic technology itself hasn't been in the mainstream all that long. I am a bit doubtful of photovoltaics that work at night, for the simple reason that at night there is less of *every* kind of energy falling on earth. Less visible light, infrared, etc. Infrared just happens to be particularly good at giving away hot objects, which is how Night Vision goggles work. For the same reason, a night vision windshield might be a very useful tool, but it would still have difficulty picking out colder objects, and those that reflected less infrared light. In other words, you might see cars and pedestrians, but you could easily miss the upcoming embankment 0.o .
Q:Solar Panel for a Science Project? Lamp as Light Source? How will this work?
Q:how the energy of solar panel measure?
Most PV solar panels are labelled with their peak power output - this is the maximum power (measured in Watts) which that panel can generate in full sunlight. Remember these simple formula- V=IR and P=VI The current flowing through load keep the flow of electrons and thus energy is produced.
Q:I need help with a solar panel?
You not only need a diode, but a circuit that opens the circuit if the voltage falls below a certain level. The diode is not the problem, but the batteries powering the solar panel when the voltage falls to low.
