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: I'm thinking of having solar panels to generate electricity. The drawbacks are that I'm afraid if it needs repair, I won't be able to find anyone. Also I'm afraid that the roof is not very accessible. If it is a new house, should the roof have a roof hatch? What can make the system not work?: Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.

Q: Can solar panels store excess energy?: No, solar panels themselves cannot store excess energy. However, energy generated by solar panels can be stored in batteries or other storage systems for later use.

Q: What are the benefits of using solar panels?: There are several benefits of using solar panels. Firstly, solar panels generate renewable and clean energy by harnessing the power of the sun, reducing our dependence on fossil fuels and reducing greenhouse gas emissions. Additionally, solar panels can help to save money on electricity bills, as they generate free electricity once installed. They also require minimal maintenance and have a long lifespan, providing a reliable source of energy for years to come. Moreover, solar panels can increase the value of a property and contribute to energy independence, especially in remote or off-grid areas. Overall, the use of solar panels promotes sustainability, cost savings, and a cleaner environment.

Q: i want to know how to hook up solar panels to my existing power. all i can find on the internet is to use batteries and a inverter. but i want to use all of my existing lights and outlets off of the solar energy. i have heard that you can actually turn the meter backwards and use supplied power when needed. thats what i want to do and is it possible to do myself and if so, how?: Contact your power company. They will advise you of the proper configuration. If you try to attempt this without notifying the power company and something goes wrong, they can and most likely will hold you responsible for all damages.

Q: Can solar panels be installed on disaster relief shelters?: Yes, solar panels can be installed on disaster relief shelters. Solar panels provide a sustainable source of energy and can help power essential equipment and devices in these shelters, such as lights, communication systems, and medical equipment. This reduces the dependency on traditional energy sources and ensures uninterrupted power supply in critical situations. Additionally, solar panels are lightweight and portable, making them suitable for temporary shelters and easy to transport to affected areas.

Q: i need to make a mini-solar car which shouldn't cost much. it's for my science project. for now, i just found out how to make a solar panel using copper oxide, but it does not generate enough power to power up the engine of the toy car [ the small engine they used in the toys, like from TAMIA]: I do not have the skills to make my own solalr panles even if I want to try it. I see the answer above but cannot understand it. I bought my solar panels from OKorder and it works for me quite well.

Q: Im looking at making a self build iPad solar panel charger, Is it possible to get a small solar panel, a battery to hold charge and then a USB output? nothing fancy, just power in and power out?: Lithium okorder / For USB power, there are some references you should seek out from the websites of Fairchild, On Semiconductor, Texas Instruments, National Semiconductor, just to name a few. There are others, and if your IPad has the control circuitry for the accurate charging of their batteries, and you just need the USB port to have the right power available, a high compliance regulator such as an LM7805 should do just fine. Spec sheets for that regulator are available through the above mentioned manufacturers websites as well.

Q: Can someone tell me the average savings you get PER solar panel installed? I do not have the money to invest in a bunch of them at once, so I am forced to buy one at a time, when I have the money. So how much can I expect to save after I buy the first one?: No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?

Q: I have a question about solar panels. What are the benefits of this system if I installed in my home. for example i know it produces electricity but does it do anything else? How many panel would you guys think I would need for 2000 sq ft. do you know if it produces hot water? Thanks for your help: First, solar panels come in two basic types - photovoltaics, which produce electricity (the black cells you normally think of), and solar thermal, which heats water (or some other fluid). It's one or the other, you could install both if you want that. Solar thermal is cost effective today, depending on how you currently heat your water. (The hot water could also be used to create electricity, like in a steam turbine, generally done in larger power plants). Photovoltaics are more expensive, but coming down in price every day. To know how many panels you need, you first have to determine how many kWH your house uses, and do you want to be completely off the grid (which would also require large batteries), or just reduce your electric bill.

Q: i need as many bad things there is about solar panels: They require the use of Silicon which requires refining. This process of refining uses non-ecofriendly chemicals. It damages the environment. Solar panels are only about 20-30% efficient whereas coal is around 60-70%. Solar panels require much space for such small output. Do note, that new solar panels are being worked on and that with the correct alignment of solar cells, solar panels may become ~80% efficient, rendering coal useless.
