Solar Module Introduction

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: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:if you put solar panels on cars, you'll be able to drive without gas in the summer and part of winter?
Solar panels, a large storage batter, an electric motor all add weight. This reduces vehicle performance and almost means more energy is required just to move it. There are some solar cars that university engineering departments race. However these solar cars are very light weight, not practical automobiles. Typically they seat only one person and no cargo. Staff actually have to follow them in regular cars with parts and equipment in case of a malfunction or breakdown.
Q:What things can a solar panel power?
What things can moving water power? It just depends on the size and number of panels.
Q:Solar panels IRS refunds?
It's not your income, but the tax you pay. This is a NON refundable credit. You won't see a difference unless you actually owe tax. If you are retired and living on social security and savings, you don't pay tax, so you'd get $0 from the solar panels. If you are married, have a bunch of kids and get a refund of all money withheld anyway, you'd get $0 from the solar panels. If you currently average, say $200 in actual income tax, your $2,000 investment would create a $3600 tax credit, but you'd only get back $200 the first year. (This would reduce the tax bill, increasing any refund of money already withheld to pay that tax bill.) The remaining amount would carry forward to 202. You can keep carrying it forward as long as the credit is available (I think that's currently 206). Get your 200 return out and get form 5695 and run the numbers. Edit, ignore TRO. She doesn't keep up with tax law changes. BOTH the residential and solar credits exist in 20. The Residential credit now limited to $500.
Q:Silicon, Polychristaline, or Solar Panel?
Some steps in making semiconductors use gases at very high temps, and solar cells might.
Q:What type of wires should i use for a solar panel?
You might want to be careful about soldering. Some panels can be easily damaged by excess heat. Check the manufactures website for recommended attachment methods. Solder tape or conductive epoxy might be better. If you do not have such things already, a good idea might be to take it into a TV repair shop or electronic hobbyist store. Some folks are kind enough to do it for you for free.
Q:Solar Panel Watts?? help!?
Ok, seeing your icon is a female, I'll take a chance and offer a possible conversion factor. In diets, you count calories. When you exercise, you burn calories per minute or hour. In one exercise session you burn a total number of calories. And remember, 000 calories = kilo-calorie = food calorie. Same with solar panels and electrical power (same stuff, different units). Solar panels come in many watts sizes, like different foods and portions have different calories produced. When these panels are exposed to sunlight, they will generate this amount of watts for as long as you expose them (the units are kilo-Watt-hours), basically, like burning calories on a bike for an hour burns a total of x calories for that hour. If you have a 2-hour day, then a 00 watt panel will generate a possible total of 2 hours x 00 watts = 200 watt-hours = .2 kilowatt-hours. Just like calories burned during regular exercise varies over the year and your mood, the solar panels will generate varying level of power (watts) depending on the weather. And just like you burn calories at different rates by age and lifestyle, an average house power use is dependent on geographic location, size of house, number of occupants, etc. No real typical profile. I would recommend you get some personalized help in sorting out your power needs, A contractor/installer can give you a quote/estimate or general class of use. A second or third quote would keep you first estimate honest. Good luck!
Q:Solar Panel Help Please!?
I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel.gov/solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
Q:Solar Power...........?
The guy put solar panels on a Datsun.
Q:Is heat a factor in how much energy is gained when using solar panels?
If you are talking about solar PV (photovoltaic), panels, (these are the solar panels that generate electricity), temperature DOES effect the power output. But it works opposite of your example. They actually work better in cooler temperatures. In other words, you will get more electricity on a cold, sunny day than you will on a warm, sunny day. The difference is not huge. It is a percentage point or two for every ten degrees cooler it is. But it is significant enough that solar system designers like myself need to know the temperature fluctuations in the area we are designing for. I know of a few improperly designed systems that were damaged on sunny winter days. Solar thermal panels (the ones that heat water) do not work this way. A warmer sunny day is usually better, but again, the difference is not huge.
