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 to find amp for solar panel project?
It is possible your meter does not have the capacity to safely measure more than 300 milliamps which is too small to measure current output from solar panels. Assuming no losses in the system or components, if your meter does not have the capacity to measure 0 Amps, you will need to get one that does. Analogs are better than digitial for this. Most often the 0 Amp circuit of the meter has a discrete positive plug location for the positive test lead. Most have a common ground connection with the rest of the meter functions. If you are measuring current at the battery in the charge mode- Negative lead of meter goes to positive terminal of battery and positive lead of meter goes to the cable that was connected to the positive terminal of the battery. Since the Wattage is a nominal measurement, if you measure between the panel and controller, take measurement on one leg of the panel, as you want to measure the current with the loaded active circuit. Meter is oriented the same way as the measurement at the battery would be made above only this time the meter is between the panel and controller. At peak solar conditions, expect current to be measured at 2.5 to3 Amps or more per panel. Under optimal conditions your panel will have higher output than their ratings indicate. Open circuit can be close to 20 volts. Never short circuit the output of the solar panels. It is volts multiplied by amps that gives you Watts.
Q:What solar panels are the most efficient?
New rollable panels are becoming available that don't have to be permanently attached to a surface and that are more resistant to damage than conventional panels. Right now they are also even less efficient than photo cells at about 0%, but the cost factor may make up the difference. Solar thermal is more efficient than photovoltaic cells. They focus sunlight with mirrors onto a pipe containing a liquid which is then heated to it's boiling point. That turns a turbine to produce power or is harnessed in some other way. The panels are cheap compared to photo cells, don't require perfect manufacture or exotic materials, no expensive maintenance and they are much easier to repair. I don't know of any available to individuals yet but there are at least two companies building generating plants in Nevada with this technology. SunPower is about 22% efficient but even at that rate it will take decades to pay for itself and the panels are unlikely to last that long at anything near optimal efficiency. The cost is just too high at present but solar thermal may provide a good alternative until photovoltaic cells mature, if you can cobble together a system. The final link is about a claimed 80% efficient solar cell that even generates some power at night. It's based on nano-technology, like many promising energy developments in batteries, electrolysis and ethanol production. If it works as advertised it should revolutionize solar tech. Eventually.
Q:How much was the price of solar panels 5 years ago compared to now?
For just 5 years ago, certainly not! Perhaps you are thinking of 50 years ago, the kind that was put on the early communication satellites? 5 years ago, there was a glut of polysilicon, so modules were actually a little cheaper than today. Solar cell makers were basically using the scraps thrown away by chipmakers. But today, more silicon goes into making solar cells than computer chips, so that bonanza is gone. We will see prices going lower this year, possibly 20% from last year, because of improvements in technology, but also an increase in polysilicon supply, and a slowdown in demand due to worldwide recession. Later this year is a good time to buy panels, if you have the cash. The industry site below tracks module prices. They used to have more data, but I guess the old data rolls off the screen with time. If you want to see the details, they'll charge you for the report.
Q:solar panel in a grid tied system?
I just costed an 85W panel I found online as paying back in 30 years. And that's without the inverter. If you want to do it to save money, look on surplus sites for chipped cells and make your own panels. You can then get the pay back time down to about 5 years, even with the 9.60/kWh price here, which is lower than many places.
Q:Solar Powered Propeller?
Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
Q:How to prevent shorting out solar panel?
Just cover the panel and cut the wire the voltage will be so low it would be like shorting out a battery
Q:where can i get a small solar panel to power an outdoor water pump?
You will need more than a small solar panel to run a pump continuously, unless you don't mind that the pump only comes on during the day while the sun is out. st you need to know what the power demands are of the pump in question. Not only do you need to know the rate of the power draw from the pump, but you will also have to calculate how much power the pump will draw from your solar system every day. You will have to factor in that the sun doesn't shine brightly every day, of course there's also night, so you will need a storage battery, charging system to go along with your solar panel. Now most pumps like the one you described are 20vac. Most solar panels, the batteries, the chargers are 2vdc. In order to get 20vac you will need an inverter. Once again, you will have to make sure that the inverter you get can handle the demands of the pump. A solar system that actually works for you takes some carefull planning, it's not something that you can just hang from a tree. None of what I just descibed will be inexpensive by my definition, so if it were me, I'd dig a trench across the driveway, install some direct bury cable on a GFCI circuit out of my main power panel save a bundle.
Q:how often do you have to replace solar panels?
Expect a water heating panel to last about the same as a water heater, 0 to 5 years. Actually, my brother's system is coming up on 5 years, and is not giving trouble yet, so maybe technology has advanced. I have actually never personally known of anyone replacing a solar electric panel due to wear-out. I have heard of occasional replacements due to accidents, including natural disasters like lightning strikes. And one brand of panels had manufacturing defects around the year 2000, but that manufacturer owned up and replaced those free of charge to their customers. A standard warranty on a solar electric panel nowadays is 25 years.
Q:Solar Panels?
Well, the best way to buy solar panels is to shop by watts. Solar panels come in a wide variety of watts, from to over 200. However, the more watts a panel has, the more it costs. I would suggest getting small things first, and gradually converting to solar power so as to help the environment and save money. If you have an outdoor pool, buy a solar collector to heat it. It will extend your swimming season and once you hook it up, you won't have to worry about it. (My cousins have this on their pool.) Also, there are solar cell phone chargers available for purchase, you could get one of those. As for your house, you would need several solar panels and a converter to be able to power your whole house on solar energy.
Q:Can you make a Solar Panel Heater?
Absolutely. But I see your point about the Ohms law. I think you'd need technical schematics to get the raw details.
