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:were can i buy decent solar panels?
Your best bet would be to go down to a place that has magazines and look through their solar magazines, like Solar Today and Home Power. In these you'll will find many places online where you can buy solar and wind power products. They also have good reviews so that you can be an informed consumer and don't end up buying poor quality products. I've seen performance reviews on a variety of models.
Q:is it feasible to create a solar panel that could harness more of the suns energy than what they can now?
If you're asking whether we can make more efficient solar panels, the answer is obviously yes. Solar panel efficiency has been slowly but surely increasing every year, although the theoretical limit is being approached (but has not yet quite been reached) by crystalline silicon devices.
Q:Solar Panel System companies at the swapmeet?
Hard to say. Solar panels are becoming more common these days. May want to ask if the vendor is licensed and bonded contractor (if he's doing installation as well as panel sales). Find out the name of the equipment that this guy is selling (panels and other hardware) and do a search. For that matter, get the guys name and do a search on it to see he pops up elsewhere.
Q:solar panels and calculations?
The okorder.com The reference section has all the formulas you are looking for and there is a list of dealers by state, plus various state rebate information. Yes, you can hook up different panels to the same system. There are special controllers that regulate the voltage. I'm more of a hands on nuts and bolts guy so I can't help you with the formulas and engineering explanations. Another great place to get information is Home Power Magazine. You can get the issues online or in print. Thanks for going solar!
Q:why wont my solar panel make my dc motor work?
You didn't say how much power your panels can produce, or how much power (current x volts) the motors require. The panels must meet or exceed what the motor requires. You might need to get a very small motor and a little gearbox out of some other motorized toy, or at least a small pinion gear for the motor and a larger ring gear that can be attached to an axle (similar to how RC cars accomplish their drive train). A worm gear drive set might be even better if the motor / solar panel combination isn't very powerful - it'll go slowly, but some movement is better than no movement. If you put the panels in series, a 2 V motor should be the best match (again, only if its power requirements are small enough). If you want to try running the 3 volt motor off the panels, you might try paralleling them (make sure you get the polarity right or they'll try to kill each other) - you'll still be mis-matched, but if the motor requires less power than the 9/2/8 volt motor(s), it might work. If you have or can acquire a multi-meter, you'll be able to measure the voltages and currents and that will not only help you see what's going on, but adding some details might help others help you get this working.
Q:Solar panel for your home?
In the short, a solar panel is composed of many solar cells...all tied together and in some sort of a frame for mounting. When energy from the sun hits it, it creates a reaction which can feed electricity through leads to a converter system which takes the Direct Current power and converts it into Alternating Current. If you rewire your house for DC products I suppoes you wo'nt need the converter. but most of these systems are retro-fits. Batteries provide back up source to the system when the sun goes down. So solar is converted to electricity through the panel, which goes to your solar system which both provides power to the house and to recharge batteries. The batteries take over when the sun is down. So you will need to know how much battery capacity you need by calculating the Amp hour rating of your applicances that you normally use at night like Microwave, TV, radio, refrigerator, etc. For some depending on the appliance....water heater (if electric) or stove) then you need to figure out how many panels you need to provide your normal daily energy use, figure out how many batteries you need, set up a distribution system that gives you what you need where you want it and wa la. Once done, you will be off the grid and paying nothing from the electrical utility. Some places due to deregulations allow you to sell excess power to local utilities too, but those systems need to meet tight standards.
Q:When I make a solar panel what kind...?
First of all you seem to be talking about making a solar photovoltaic panel instead of a solar thermal panel. Most solar panels will produce DC electricity. Your house uses AC electricity. You can set up the solar photovoltaic panels to send their current to charge a battery bank and then you can tap into that battery bank and send the power to a voltage inverter to change the power to AC. The better inverters will do a better job of this. The system has to be matched and sized properly. If you are not familiar with electrical work you should have someone who is more knowledgeable help or do the work. Good luck with your project.
Q:How many LED's can power a solar panel?
Your question has a lot of science involved that I don't understand perhaps the link posted in my source for this answer could help you out? It a site containing only info on LED Lights. Good Luck
Q:Where can I get free solar panels?
Trees, they have plenty of leaves. You'll probably have to buy an educational kit from Radio Shack or something like that. Maybe break some old solar powered calculators open.
Q:How to connect solar panels to batteries?
20 volts is a common open-circuit voltage for nominal 2v panels. The panels put out about 5v at full load. If the panel puts out little enough that it takes 20 hours or more to put a full charge in the battery you can get by without a charge controller - just keep the cells topped up with distilled water. A charge controller will do a more efficient job, though. The most efficient charge controllers use what's called Maximum Power Point Technology (MPPT) which lets the panels operate at their most efficient point throughout the battery's charging cycle. Available on OKorder. The charge controller should have the same or higher wattage as the panels it controls - if you're not sure of wattage, assume that they are the same as similar area panels you find for sale. Before buying a charge controller, connect the panels through an ammeter to a discharged battery. They may have been trashed because of damage and low output. You need at least an amp for trickle charge, 5 amps for reasonable recharge times.
