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: Hello from SO TX.. I would like to know if anyone out there has SOLAR PANELS on their home?I have a 850 sq ft. house. I called Austin to a company that offers panels and installation. The cost $8,000.00, for 0 panels . The rep said we would save about 2 to 25% on our electric bill /mo. We use approximately 980 kw/mo. Our bill is around $40.00 / mo...I really don't think that's a good enough savings. We figure it would take 25 years to recoup our investment.And where we live in TX it does not offer any incentives. The gov. allows you a $2000.00 tx break.: $8,000 invested at 5% interest would pay you $900 per year for the rest of your life. If you spend $40 per month and would save 25% of that, you would save $420 per year. To be fair, the savings would creep up with the electric rates but this would be off-set by maintenance cost and equipment attrition.

Q: Can I install my 2v solar panel straight to battery to charge the battery on my 989 ford ranger?: No, there is no way that you can install solar panel in your truck battery. For your information, solar panel works only if it is stable mode and consuming solar energy. So, think about it, does your moving truck can give what a solar panel need to run it.

Q: I would like to know if I had a mobile kitchen could I power it from solar panels mounted atop the vehicle (truck).(to power electric kitchen equipment, i.e. stove, deep fryer.), instead of propane…could I possibly connect the solar panels to a battery to save my generated electricity? If solar panels would not be enough power could a small windmill suffice…?: The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^

Q: I want to buy a solar panel to charge deep cycle batteries and charge electronics off the DCB. I don't know how to wire everything up though or what materials ill need. Inverter? Gauge of the wire? Ampmeter?: the solar panel should state it, you dont need a inverter to charge, only to use the power from the cell.you do need an amp regulator, so it tells if the battery is on full charge and so the sun doesnt over power the battery through the solar panel

Q: Can solar panels be installed on ground-mounted structures?: Yes, solar panels can be installed on ground-mounted structures. Ground-mounted solar panel systems are commonly used when there is limited space on rooftops or when the optimal orientation and tilt angles cannot be achieved on a building's roof. Ground-mounted structures provide flexibility in panel placement, allowing for optimal sun exposure and ease of maintenance.

Q: Can solar panels be installed on a church or religious building?: Yes, solar panels can be installed on a church or religious building. In fact, many religious organizations have embraced renewable energy and installed solar panels to reduce their carbon footprint and lower their energy costs.

Q: Can solar panels be installed on beach resorts?: Yes, solar panels can be installed on beach resorts. In fact, beach resorts are an ideal location for solar panel installations due to their large open spaces, ample sunlight, and potential for reduced electricity costs. Installing solar panels on beach resorts can help them become more sustainable, reduce their carbon footprint, and contribute towards a cleaner and greener environment.

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: Well my dad has been into Solar panels for quite a while, his birthday is coming up and i want to get him a small minature one, so he can toy around with it and be able to use it as expirience for when he gets a bigger one. my dad has been doing ALOT of studying, and i've been looking online but idk what kinda kits to get so should i get a 0w kit, 5w kit, or 20w kit? which one would be best to fool around with and play with? thanks: The okorder /... All the other sites you google/yahoo for will be advertisements. I think the author of this one was a engineering student. Hope this helps!

Q: Can solar panels be installed on a school or university campus?: Yes, solar panels can be installed on a school or university campus. Many educational institutions are adopting solar energy as a sustainable and cost-effective solution for their energy needs. Installing solar panels not only reduces greenhouse gas emissions but also provides educational opportunities for students to learn about renewable energy. Additionally, it can save the institution money on electricity bills and potentially generate revenue through excess energy production.
