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:solar panels!!they are fantastic! cause they are the new way of quot;chargingyour home, without killing the earth!would you install them, or not? and make sure you say WHY
I believe the best economy comes out when a completely green house is built. Solar panels are expensive, and I'll rather use some of the investments to build different back-up systems, instead of bying solar panels for it all. If I build another house, my fancy stuff would be the green stuff. The house will have a water radiator heating system and a heat pump to circulate warm or cold air in the house. Heat pump also used to heat water for heating system. I'll use solar panels to make enough electric power . charging a deep cycle battery pack for back up power, 2. to power heat pump, fridges., freezers, and water pumps, when I'm not home at the house. When I'm home I'll run a bio-fueled(bio-waste and pellets or firewood) powered steam engine with a 0KW 0-220V generator when I need electric stove and oven, dishwasher and laundry appliances. I'll use a wood stove, BBQ and oven on the porch for summer cooking. I'll use excessive heat from steam engine for heating water tank. I'll also have an bio-fueled (waste and pellets or firewood) water heater for winter heating back-up. Of course I'll make sure I'm connected to the electric grid, so I can get credit from power company for the excessive electricity that will occasionally come out from solar panels. Steam engine can be replaced by diesel powered 0KW generator, if it's possible to fuel it with veg-oil home made diesel fuel. Depends whats most accessible at my living site.
Q:Can solar panels be used for powering water treatment plants?
Yes, solar panels can be used for powering water treatment plants. Solar energy can be harnessed through photovoltaic panels to generate electricity, which can then be used to power the various processes involved in water treatment plants. This renewable energy source offers a sustainable and environmentally-friendly solution for powering water treatment facilities.
Q:can solar panels be on houses? malls?stores? WHAT ABOUT TRAINS?
Solar panel is an alternative source of energy. Solar panels are like plants, they take energy from sunlight. Only in solar panels, electricity is produced instead of oxygen. This electricity is used to power homes just like cable electricity.
Q:I've been looking into solar panels. They are fairly expensive ($35k or so). My state has some rebates and grants available. Is anyone aware of any federal grants and rebates other than the federal tax credit? We are subject to AMT tax and can't take the credit. (Which is ridiculous, is the federal government committed to conservation or aren't they??????)
whether you advise water heating or electrical energy, i could advise contacting a expert installer, who will provide a quote, and generally has a variety or 2 of panel that they choose. image voltaic electric powered can save money, however the form of gadget that usually does isn't an effortless self-installation. yet to respond to immediately, i could make particular the panels are crystalline (monocrystalline or polycrystalline) silicon, and make particular they have a 25-2 months guarantee. it is enormously plenty everyday between all significant manufacturers. After that, i could circulate by potential of cost according to watt on my own.
Q:Can solar panels be used to power a disaster relief operation?
Yes, solar panels can be used to power a disaster relief operation. Solar panels are a viable and sustainable source of energy that can be deployed quickly in disaster-stricken areas. They can provide electricity for charging communication devices, running medical equipment, powering lighting systems, and supporting other essential operations during relief efforts. Additionally, solar panels are independent of existing power grids and can be set up in remote or inaccessible locations, making them an excellent solution for providing energy in emergency situations.
Q:I am currently building a house, iv designed it to be as self sustainable as possible, I'm in the process of installing solar panels but as I'm ordering online I was hoping someone here could tell me how many I would need to completely run a 5 bedroom home, just standard household appliances such as fridge and freezers, plasma tvs computers and of course lighting, various things like that, also I'll need power storage as well, some type of large rechargeable battery, any help would be great.

Q:why don't we take a cue from mother nature and make our soar panels like trees? thousands of leaves or needle (like a pine tree) instead of one big flat panel? I mean it seems to work pretty good for all the plants i see why would it not work for us. It would be aesthetically pleasing and with the right engineering wouldn't it make them not have to worry about tracking the sun? i already have some ideas about the process of making them just no available labratory.
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:Maximum size of solar panel i have to use is - 8 * 5 feet - this is the limitation given to us.
As in the reply to the other version of your question - you should be able to get that wattage much of the time during full daylight from the area you specify, but your location, weather, and ability to mount the panel(s) at the best angle to the sun at time you most need the energy (winter? summer?) Instead of going with guess work on the efficiency of the panels you are considering, the people who want to sell you panels (or their website) should be able to tell you from the angle of your mount (roof?) and location, etc., an estimate of the average and maximum power available and the kWH during various seasons. This has to be known for either buying the batteries for storage or knowing the economics of feeding back into the grid, depending on the method used.
Q:i am doing this group project fro school. I would like to know if anybody knows anything about how to read a Spec. Sheet on Solar panels and where I could go to start researching them. Anything would be great!
i think of you may desire to examine slightly extra approximately photograph voltaic capability and battery utilization. possibly you heavily isn't waiting to do this effectively with an on board photograph voltaic gadget. examine the wattage (volts situations cutting-edge) of the motor. you would be fortunate to get 0 watts according to sq. foot from a photo voltaic panel at midday on the excellent day. thinking the sq. photos necessary the dimensions and weight of a fee controller you need to be extra advantageous off with connection to a distant charger, powered from AC
Q:For those solar panels that you install on your rooftops, do they generate electricity when it's cloudy? And if yes, how much electricity does it generate compared to sunny days? For example...like only 25% electricity generated compared to sunny days?
No, silicon photovoltaics reacts to a very specific frequency of infrared light which matches the bandgap energy of it's outer electron shell. This frequency is reflected by clouds. However, thermal solar collectors such as evacuated tube collectors can function under cloudy skies albeit at a lower rate and there is at least one hybrid photovoltaic and thermal panel designed to take advantage of this.
