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. 


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:How Do solar panels work?
Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
Q:How Can I Reduce A Solar Panels Output To 3volts From 9volts?

Q:where does the solar energy go to when it hits the solar panel?
Visible light from the sun is in the form of photon before hitting the solar panel. In a silicon solar panel, the photon is caught by the semiconductor material. Energy equivalent of the photon is then used to excite an electron from the semiconductor molecule. The aggregate of free flowing electrons form the current in a closed electric circuit. The efficency of conversion from sun light to electricity is not 00%. The majority of light energy hitting the solar panel is dissipated in the form of heat. As technology advances, the conversion efficiency is improving, hence reducing the cost of solar energy.
Q:Do solar panels generate power when it's cloudy?
From my understanding they generate electricity when the suns out and when its out and there aren't too many clouds around covering up. They store some electricity for the winter and cloudier times but I'm not really an expert!
Q:Where can I get free solar panels?
Trees, they have plenty of leaves. You'll probably have to buy an educational kit from Radio Shack or something like that. Maybe break some old solar powered calculators open.
Q:Using a solar panel to make energy?
It is quite complex from an engineering point of view. If the objective is academic, then it is worth the education for a small system. If it is to save money, whether it is viable depends what are the current rates where U are and a whole bunch of issues. The current technologies available are very far from one size fits all! Hope this answers your question
Q:Can I install solar panel straight to battery on my truck?
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:Can I power up 2Watt bulb using 2Watt solar panel power?
Unlikely - at least not a full brightness. You have to match voltages. If your panel is 2v at amp, it won't run a 20v bulb that runs at /0 amp. You're also going to lose power in the wiring and other components that means the 2w panel won't really deliver its full rating. And I'm also guessing that the 2w of the panel is only under full, bright sunlight, so any lessening of the light; clouds, haze, fog, dust, will lessen the power available.
Q:I want to buy solar panels?
You will not recoup your cost in utilities savings. you will get it back in state and federal tax credits and accelerated depreciation on the system. You also have to be aware that a KV system for example is different in different climates. I just priced a system that is in Malibu,CA and it is very efficient due to sun exposure. the same system in Idaho will not create the same amount of power output. Therefore will not save the same amount on utilities. I have included a plug and play system that just came on the market. But there are other systems available.
Q:2 Questions on Solar Panels?
Solar panels are available in a wide variety of power ratings.  Energy is the sum of power over time, so how much energy a panel produces depends on the intensity of the light hitting it and how long it's applied. I understand that current single-crystal silicon PV panels are warranted to produce ~85% of their rated output for 25 years.  Most will do better, and will produce useful output for perhaps 50 years or more.
