Solar Module Introduction

Solar Module is the core part of solar PV power systems, also is the highest value part of it. The function of Solar Module is to convert the sun's radiation to electrical energy, or transfer it to battery and store in it, or to drive the load running.
The Product has been widely used in space and ground, it mainly used for power generation systems, charging systems, road lighting and traffic signs areas. It could offer
a wide range of power and voltage, and with high conversion efficiency, and long service life.

Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. These early solar modules were first used in space in 1958.

Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. The cells must be connected electrically to one another and to the rest of the system. Externally, popular terrestrial usage photovoltaic modules use MC3 (older) or MC4 connectors to facilitate easy weatherproof connections to the rest of the system.

Q:How does Solar Panels works and what is the cost of getting a solar panel installed.?
Solar okorder.com
Q:What do I need to install a 40 watt solar panel?
There okorder.com/ Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:Can a solar panel work with an inverter?
There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
Q:is my solar panel big enough?
If a car battery contains 50 amp hours of charge at 2 volts, that's 600 watt hours of energy. divided by 34.03 watts, 7.63 hours to charge completely in direct sunlight. You don't want to connect them all in series. You want about 4 or 5 volts to charge a 2 v battery, so you should connect groups in parallel, and connect those groups in series to make your voltage. You'll end up with the same amount of power, lower volts and higher amps. It will work for trickle charging your battery if it's not too far run down.
Q:any one know about electricity solar panels?
The charger will accept whatever current is necessary from the solar panel up to 7A. It's not like the solar panel will force 2amps into the charger/battery -- the charger will control the current going to the battery. I question whether or not the 2V panel will actually charge the battery, though, because in order to charge a standard lead-acid 2V battery you need to have about 4.5 volts applied to the terminals. Perhaps the charger has a boost circuit -- I don't know without looking at it or knowing the brand/model number, etc. The timer must be 2VDC, but, if you only have a timer that is rated for 20VAC, you can buy a small inverter that will take 2V and supply the necessary 20VAC. An inverter rated for 20 to 50 Watts should be sufficient. These usually cost under US$25. .
Q:how much does solar panels cost for you home?
I just got a quote for my place. It came out $8/Watt installed. The quote was for 24 - 20W panels. Dividing the total quoted price by the 24 panels comes out to $,750 per panel. This includes the complete system with the converter and cutoff switch to connect it to the grid. This is also a top-of-the-line system. There are cheaper systems with shorter life spans. My quote was for a system with a 30 year life expectancy. There is a Federal tax credit in 2009 of 30% that will bring the system cost down. There are also nice state tax incentives in CA.
Q:What equation would i need to determine the raise in temperature of water going through a thermal solar panel?
solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.
Q:what are bad things about solar panels?
They're really expensive. If you want it for practical use like a house or car powering system. They're bigger than like a battery if you're comparing size to power. Like a car battery can produce more energy than a 6 x 4 panel (just an example)
Q:solar panel, dc light help?
You can't really judge the watts for solar lighting the same way you could for dc lighting. This is because of several factors The lights that you showed ARE NOT high quality lights and furthermore; they are not a well-known brand. Also, I would be suspicious of any store that offers lights for less than half of what other stores do. They are dumping the merchandise, which means it could have been sitting around for a while. MAXSA Innovations makes good solar lamps, so does Solar Goes Green. As the other responder wrote, you are better off using dedicated solar spot lights or floodlights than trying to integrate a solar panel into regular solar lights. A 00 Watt solar panel is pretty strong, and you also would need a battery. Unless you know how to rig up the system with appropriate controllers to make sure too much energy doesn't get into the rechargeable battery (lithium ion or NiMH), you take a risk on having the whole system fry out.
Q:Can a solar panel be used as a NiCd cordless tool battery charger?
Two of those solar panels connected in series will easily charge a 8V battery. I would not even be concerned about over voltage the solar cells will have plenty of internal resistance.
