Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.

Dozens of these PV cells are packaged together into solar modules, which in turn are packaged into solar panels that are mounted on a rooftop and arranged to maximize their hours of exposure to direct sunlight. Because the electricity generated by all those solar cells is direct current (DC), it is then sent to an inverter that transforms the power into the same alternating current (AC) used by the appliances in your home and the local utility electricity distribution grid. Increasingly, these inverters are getting "smart," providing data monitoring for solar installation performance and other grid integration services.

Q:How Can I Reduce A Solar Panels Output To 3volts From 9volts?
Solar panels generate DC power. Changing DC voltage is hard, which is why the power grid is AC voltage. AC voltage can easily be changed with a transformer. To keep the DC power (watts) the same at a lower voltage you need a DC to DC converter. That basically changes the power to AC with an inverter, changes the AC voltage to the new value, then rectifies it back to DC. It is probably hard to find a commercial unit that handles those voltages and then it will be expensive. But I have a simple solution in the special case of a solar panel. Solar panels are made up of smaller solar cells. The basic solar cell has a very low voltage, like half a volt. The panel has many of them connected in series to make a higher voltage. Just cover (shade) some of them and the voltage generated by the panel will be less. Of course that reduces the power. And you may need to experiment with shading different parts of the panel and measuring the result with volt meter.
Q:What would happen if a car ran over a solar panel?
Even running over one with a mountain bike will break the pannel. Now depending on how you run it over it might still produce power. If the circut is unbroken then what ever cells were not shattered and severed will work but most likely at a lesser capacity.
Q:Solar Panel load resistors?
Look at the graph data that looks like a rotated L. That is what voltage as a function of current characteristically behaves. The highest voltage value is called open circuit voltage (Voc). The current at lowest voltage value is called short circuit current (Isc). If you notice, a second curve is plotted that looks like a hill. That curve is power output as a function of voltage. At the peak of said hill, you get the most utility of your PV module, as you output the maximum power possible, and that is the nameplate value for the PV module's power rating.
Q:what colour can solar panels be ?
I have only seen solar panels in a dark blue because of the material they are made of. Now the case can be any color I guess but aluminum (silver) seems to be common.
Q:Is it truE thet solar panels. . ?
It is a system, you can get a small scale panel that can do things like charge cel phones and ipods. The type of system I have installed on my home needs a converter that turns the dc current that is produced by the panels into ac current to run in my home. I don't have a battery system because I'm not off the grid. When I'm generating more electricity than I am using I sell it back to my utility and at night when I'm not gernerating any electricity I buy it back again. Basically my meter runs backwards durning the day and frontwards during the night.
Q:how do you make solar panel?
Solar panel is a sheet of highly expensive, purest Silicon manufactured in a factory of exceptional killingly stringent specifications. You can't do that as a cottage industry, at least the material.
Q:Would you put solar panels on your home? and why?
If your house was not built to include solar panels, it may encounter problems that most people do not consider. For example, your neighbor may plant trees nearby and they could shade your panels. Your house may not have good alignment with the sun, so your net hours of sunshine may be too small. If your local planning folks allow panels and your house is oriented properly to the sun and no trees will block the sun, I suspect it will be a good investment long term. Still the up front cost is high. I feel that common folk like myself would be better served if we could buy shares in our local power company by purchasing a number of panels ... offered and installed by them ... and that we would then get a net monitoring of both our own electrical use and a reduction on our electric bill for the portion of our investment. That way, it seems we could each make a small investment in solar and add to that investment as we earn more money ... and essentially eliminate the need for new centralized power plants. How many malls does your city have that are completely empty and could be returned to the community as a mini power plant site. My city is loaded with malls that nobody uses anymore. Businesses move and and fail because nobody goes there. They go to the new more sexy malls. Several of these outdated malls have power lines running directly through their empty parking lots. Why not have community solar investments in these sites? Every building could include solar panels and the entire parking lot could be covered with panels. The inside of the building could still be used for other routine purposes. The local power company would be the perfect organizer and maintainer. This way solar would not be so expensive. The cost would be shared by many and so would the rewards.
Q:what is the best solar panels to buy?
Instead of paying for electricity, for the past three years I've actually ended up with a cheque from the power company believe it or not! :) I got some extremely cheap solar panels from this guide I read, I'll try and find a link for you.. that's one less thing to worry about during the recession I suppose! Haha The guide I used was here: tiny.cc/solar789 my mum was the one who said I should take a look at it, since she's been using the techniques for donkey's years.
Q:Were solar panels made by copying how plants collect sunlight?
Solar panels may have been inspired by leaves, by they don't function in the same way. Leaves use the sunlight to make carbon dioxide into carbohydrates. Solar-panels makes sunlight into electricity.
Q:Solar Panel questions...?
the first person is absolutely wrong. A 200 watt panel is $000US. By the time you buy mounting systems, wire, inverters, electric panels, interconnects, labor and permits/inspections, the cost is about $7/watt. if you use 700 kw-hr (please look at the units, you use kw-hr NOT kw) per month that 24 kw-hr per day. in your area, a pv system will supply about 4 hours at peak production of the panels, so you will need 6kw in panels, that's about 30 panel or $42,000 in equipment.
