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:Chem question regarding using solar panels ....?
It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
Q:Do solar panels plug into an outlet?
Solar panels can be connected to your household wiring with a piece of equipment called a grid tie inverter. You power company will probably require either an automatic or manual means for disconnecting your equipment from their grid in the event of a power outage or line maintainence. Homepower Magazine is an excellent source for information about solar and other alternative energy sources. A primer on the basics of solar electricity can be found using the first link below. You can download a free sample issue of the magazine using the second link below. The sample issue being offered changes occasionally. Don
Q:Solar Panel House?

Q:Can I plug a solar panel into a wall socket to lower my electric bill?
The other responders have given partial information. The electricity in your house is 20 volts AC and the solar panel will produce DC voltage. If you plugged in the solar panel into the wall, the solar panel would be destroyed, possibly with disastrous results. If you connected the solar panel to a DC to AC inverter, there are also dangers. The solar panel unless very large will not produce enough power to make a lot of AC, for every amp of 20 volt AC, you require more than 0 Amps of DC voltage. So most small solar panels are used to trickle charge a 2 volt battery used in backup situation. The problem is that the house AC and the inverter AC have to be exactly in phase or again you have disastrous results. If they are exactly 80 degrees out of phase, the wires now are carrying 240 volts and you will burn out the inverter, and possibly cause a fire. There are systems that will synchronize an inverter to commercial power so that you can feed the power back to the grid, but these are more complicated. If you want to use the battery and solar panel to run some lights during power failures, then you can connect the light to the common terminals of a switch, but the switch must be a break before make switch, which means that when you throw the switch the common is disconnected from the one source before it is connected to another source. Most AC switches will do this, but make sure.
Q:Do solar panels keep a structure cooler?
I asked the same question once to a PV install during a seminar a few years back, and he explained the following: No, PV panels do not reflect or absorb much heat from going into the building below but there is a reason for this: PV panels that reflect / absorb heat produce less electricity. They are designed to Thermally Transparent. Even worse if installed incorrectly without a good angle and air gap to allow the heat to escape the panels will actually trap this heat and increase the interior temperature of the building below! Below is the scientific analysis that is quite verbose but has two nice graphs at the end. To summarize: Adding PV panels, at best, shaded the building enough to reduce the load of the interior A/C unit by .8 kWh/sq-m/year. The electricity generated by the panels was about 356 kWh/sq-m/year. You can see the big advantage of PV panels is to make power, not reflect heat. Proper insulation is much cheaper and will do a much better job. Don’t worry, I was shocked too, but like anything it makes sense after it is explained.
Q:Maintenance for solar panels....?
All panels should be cleaned to function best. Brush or wash off dirt and leaves. They should be checked for structural integrity and lack of rust. Solar Thermal panels should be checked for signs of leaks and/or discharge from pressure relief valves. Solar Photovoltaic should be checked for electrical function and grounding.
Q:QUestion about portable Solar Panels.. Mine is 2v?
Your portable panel is at most a few amps at 2 volts nominal.Hopefully you have a higher voltage than this to enable you to charge a 2 volt battery. This takes about 3.3-3.6 volts. Your converter will function until a battery reaches about 0.5 volts (drop out voltages vary greatly). A deep discharge marine batttery will be the best bet for storage but usually more expensive than a regular battery. If your resources are limited, you might try from these cheaper sources. Insterstate battery stores usually have blems at a lower price. These are totally functional batteries but have surface imperfections that the manufacturer doesn't want his name on. Also check you local junkyard or towing service. They are often asked by insurance carriers to junk a car which has been wrecked. Many times the batteries are still perfect. They sell these for what they can get for them. Look for one from a SUV with lots of power options. Often kids cars have outlandish stereo systems requiring heaavy current batteries. These are a good find. Consider getting a solar power management system for charging your system. It will limit your charging voltage so you do not float a 2 volt battery above 4 volts where it would slowly destroy it.
Q:Why should people use solar panels more for houses?
Right now, the U.S. government and some state governments (like California) are offering subsidies on solar panels for businesses and houses. With these subsidies, anyone infesting in solar power today will have their investment returned in less than 0 years. This means that with these subsidies, solar panels are basically paying for themselves; they're free. In addition, excess power generated on solar panels can be added to the local power grid and, if you're lucky and can set it up with your local power distributor, the power company will pay you for the power you generate. This are just financial reasons. Their is also the reduction of power generated by fossil fuels when using solar power which mitigates climate change.
Q:where to face solar panels?
Not compass south, but solar south. It's easy to find. Google Find Solar south and you can get directions. Even better are trackers, that will let your panels track the sun all day.
Q:Is this a good kit for building a solar panel?
i like Eric's answer. that is conceivable to construct your man or woman panels via wiring mutually man or woman photograph voltaic cells. that is an exciting element of do, yet isn't a thank you to save money. in view that such panels are unlawful to hook up with the grid, you could result making use of them with batteries, and paying extra for electrical energy than in simple terms paying for it from the electrical powered company. photograph voltaic can ultimately save money, yet to do this, you often spend the equivalent of five, 0, possibly 5 years of electric expenses up front, then have decreased or close to-0 expenses thereafter. once you're obtainable, truthfully look into installation extra insulation and weatherproofing on your place. you additionally can evaluate paying for and installation a photograph voltaic water heater.
