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:Using solar panels to replace electrical wiring?
A solar panel does not replace the wiring in your house. All it does is supply power to the house, the same way a line in from the street does. After the power gets to the house, regardless of how it got to your house, it goes through exactly the same wiring to get to outlets and lights. Your problem is not that the power coming in from the street is insufficient; the power company can supply all you'd ever need. The problem is that your houses are not wired to receive or use more power. You need to upgrade the service panel so it can bring more power into the house, and upgrade the wiring inside the walls so you have the number of outlets and lights required by today's codes and which most of us need for all the things we plug in these days. Solar panels, while they are cheaper than ever, are not a low cost thing to install. It will take years to recover their cost, and if the rules are the same where you are as they are here, you can't use the cost of installing them as a write-off against the cost of the house until you sell it. They are a capital expense, not a maintenance and repair deduction which you can use each year against the income you receive from the rental. Doing a conventional rewiring is your best bet.
Q:Why do solar panels burn out?
You can search on solar panel failure mechanisms for scholarly works. Amorphous silicon thin-film panels go through an annealing, and power drops off after a couple years. This includes most of those flexible rubber mat type panels. That's why those are not used on serious installations. Serious panels intended for rooftop service generally come with a 25-year warranty, suggesting that the technology is more reliable than your washer, dryer, TV, computer, dishwasher, or water heater. One brand of panel had trouble about 0 years ago, but the manufacturer replaced all that were turned in, even paying shipping both ways. It was a problem with that particular model, not the technology. Our polysilicon panels have been on the roof for 3 years, now, and I've seen no sign of wear, yet, either electrically or mechanically.
Q:Why only Photo-Voltaic solar panels?
Just read some of the other posts and I am surprised at the answers. Solar thermal systems typically have a payback of less than seven years on residential system without the tax break. A complete system can be installed for about 5k or less. Compare that to 20k or more for PV with a fifteen to twenty year pay off. Each home and area is different so a site evaluation must be done for exact figures and pay offs. I am going off my own experience in my above statements Flat panel collectors work well in most areas for DHW. Evacuated tubes often run too hot which works well for some applications or high usage. Heating water is the single greatest energy usage other than space heating and cooling. It often surpasses the two above systems based on its widespread usage(every houshold in USA has one) and its the amount it is used(24/7@365) The amount of energy spent to heat water is by order of magnitude the greatest number out there. Having a solar thermal system providing hot water for a average American household is equivalent to taking 40,000 miles off the freeway in a car every year. The BTU's required to heat the water is huge. So why is this more developed cheaper and more efficient technology behind PV in awareness? Natural Gas the number one choice for heating water is cheap. It's by product is invisible and misunderstood. What I find fascinating is if you look at the increase in Natural Gas vs Electricity you will be surprised by how much it has jumped in the last seven years. It is not talked about nearly as much as electricity It does not get the same level of press that PV does. So in short the answer is cheap Natural Gas prices and public perception of this product have kept it off the list of many that are turning toward the green trend. It is less sexy than watching your meter spin backwards. It is the best improvement at the best cost except for conservation which is and was the most cost effective energy saving that can be employed
Q:Can I hook up a Solar Panel to a car battery? Does it matter the kind of car battery?
A 2 volt battery is a 2 volt battery. Some are larger than others. Sure you can charge a car battery with a solar panel, but 00 watts for a long time could be a problem. There's one way to find out.
Q:How to hook up a Solar Panel To a single outlet?
That solar panel puts out about amp (in round numbers). If you are talking about a 20vac outlet, you'll have to send the output of the solar panel through an inverter. That brings it up to 20vac. 20 watts at 20 volts means you'll only be able to draw 0.6667 amps. With an inverter at 85% efficiency, you'll only get about 0.4 amps. That would barely light a CFL. 20 watts of power at 7 volts = amp (in round numbers) 20 watts of power at 20vac = 0.6667 amp (in round numbers) Power (watts) = current x voltage. If you increase voltate, you must decrease current to get the same watts. Watts is the common denominator in power measurement.
Q:Sizing solar PV panels?
75 amps @ 240VDC is 8,000 watts.
Q:How much does a race car that uses solar panel cost?
Solar okorder.com/
Q:Information on making solar panels?
Typical solar panels like Engineer describes require a lot of space. A single panel may only light a single light bulb. You may want to look into a different way of generating electricity with solar, it doesn't use a cell to turn the sunlight into electricity, instead it uses mirrors to focus the sunlight onto a pipe between the mirrors. The heat causes water or another liquid in the pipe to boil and the steam created turns a turbine that produces the electricity. It has the potential to be less high-tech, more forgiving of minor design and structural problems and more affordable. I don't know of any system that is privately available but you can get more info at the link below. They're building a full test facility in Nevada right now. You could presumably cobble something like this up on your own.
Q:Is it worth getting solar panels fitted on my roof?
View okorder.com/. Too expensive and it may be illegal.
Q:How much power does the solar panel produce?
I sincerely doubt that you have a solar panel that is 4% efficient at converting sunlight to electricity.
