Production description

A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. 

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.

Depending on construction, photovoltaic modules can produce electricity from a range of frequencies of light, but usually cannot cover the entire solar range (specifically, ultraviolet, infrared and low or diffused light). Hence, much of the incident sunlight energy is wasted by solar modules, and they can give far higher efficiencies if illuminated with monochromatic light. Therefore, another design concept is to split the light into different wavelength ranges and direct the beams onto different cells tuned to those ranges.[citation needed] This has been projected to be capable of raising efficiency by 50%. Scientists from Spectrolab, a subsidiary of Boeing, have reported development of multijunction solar cells with an efficiency of more than 40%, a new world record for solar photovoltaic cells.[2] The Spectrolab scientists also predict that concentrator solar cells could achieve efficiencies of more than 45% or even 50% in the future, with theoretical efficiencies being about 58% in cells with more than three junctions.

Q:I have a cabin in the woods and need more light. I do have enough sun but I was wondering how or where do I get a solar panel to lead to a power outlet? In a perfect world I would like to get a solar panel with a connecting wire to an outlet or something so I could power a small TV. I know its hard enough but can I get that pre-made? Or even lastly should I look at wind power consider I would like this to be under $500? Thank you for putting up with this bundle of questions.

Q:hey so im doing this project for my technology class and i was wondering what different colours solar panels can be. also is it possible to have kentic power as a back up power if batteries dont work? thx in advance
Panels can come in a selection of colors, and trimmed in a variety of frames. Most are dark, black, blue or reddish in hue. Concentrators may appear white from a distance. Kinetic back up is possible in the form of a flywheel. Not very common but it is out there. Another form of kinetic backup that is used by some power companies is hydro. When the sun is out and the system is producing more than is used, the excess can be used to pump water uphill to a holding tank. Then when there is a demand, the water is allowed to flow back down turning a turbine to generate electricity.
Q:Can solar panels be used in remote areas?
Yes, solar panels can be used in remote areas. Solar panels can harness energy from the sun to generate electricity, making them a suitable and sustainable option in areas where access to grid electricity is limited or nonexistent. Their ability to operate independently of traditional power sources makes solar panels a practical choice in remote locations, providing clean and reliable energy for various applications.
Q:i am looking for solar panels and wind mill to put around our house and i was wondering were to find them
From a decent solar panel store. Or you can get on the Internet and look for someone in your area.
Q:Are solar panels safe?
Yes, solar panels are safe. They are designed and installed to meet strict safety standards. They do not produce any emissions, and the risks associated with solar panels are extremely low. However, it is important to ensure proper installation and maintenance to maximize safety.
Q:what is needed beside the panels and do you need an electrician to hook it up
A decent installation needs a solar engineer to make sure the panels are aligned to take advantage of all the solar it can get. that or You need to hit the books on solar radiation. online I would try different programs to get the feel. we get less solar radiating in the winter then in the summer. this needs to correctly compensated.
Q:Can solar panels be installed in areas with high humidity?
Yes, solar panels can be installed in areas with high humidity. High humidity does not significantly affect the performance or efficiency of solar panels. However, it is important to ensure regular maintenance and cleaning of the panels to mitigate any potential issues caused by dust, dirt, or moisture buildup.
Q:How could I find out what the amp output of a solar panel? Specifically, I want to know how many milliamps can the solar panel on a Casio fx-260 put out?
You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.
Q:Can solar panels be connected to the grid?
Yes, solar panels can be connected to the grid through a process called grid-tie or grid-connected system. This allows excess electricity generated by the solar panels to be fed back into the grid, reducing reliance on traditional power sources and potentially earning credits or payments from the utility company.
