- Q:I'm about to buy one but I don't really know which one is best for my home.
- One will give you enough DC voltage to light a 25 watt light bulb, [ one 45 watt panel is around $400. ] Now if your wanting AC voltage You have to buy a inverter, 5 or 6 deep cycle batteries, a switch Cables to transfer the voltage, a place out side to store the batteries, instalation brackets for the roof A Permit to Install them
- Q:What is the most powerful solar panel made?
- There are various solar farms that run turbine generators that have some rather large arrays. I suspect they'd be in the southwest but i've seen pictures of them covering a few acres. You won't find very large panels because its best to keep the panels small and just have a lot of them. This is because its much easier to have a thousand 0m^3 panels then huge 0000m^3 panel because you achieve best performance when you can align the solar panels to always face the sun. With a huge panel, you would need it to be high off the ground so it can manuver around. Small ones can all be menuvered on a small scale only a few feet off the ground so they can all be pointing towards the sun to gather the most light.
- Q:discription how does solar panels save energy
- Solar panels don't save energy, they just utilize a different source of energy. To the extent that it replaces energy from sources which are limited themselves (such as fossil fuels), solar energy does save those resources.* The main benefits of solar energy are environmental in the sense that it is nonpolluting,* but using solar energy doesn't reduce actual power consumption. *Excludes environmental costs of producing the solar panels themselves, but these are much smaller than the environmental benefits of solar vs. fossil fuel (which has infrastructure costs of its own).
- Q:If you were to be asked to write a material(s) report on either -solar panelsor -aircraft fuselageWhich would you choose?well i was asked to choose between these two,so i guess that if i choose what the majority wouldn't, i might just score a little bit higher,what do you think?if you are the lecturer you would want something different right?
- Solar Panels. Solar panels is a generic term for any semiconductor that converts solar energy to electrical energy. However there many different kinds of solar panels and constructed in different ways from different materials. There is the generic polysilicon solar panels for residential installation on one end of the spectrum. On the other end are very high efficiency (and expensive) solar cells used on the Mars Orbiter that are constructed of so called triple junction GaAs/Ge solar cells. In addition there are also the thin film solar cells that are being researched that use Cadmium Telluride (CdTe) to form junctions and make very efficient cells on very thin substrates. I would say that research into materials that can be used for solar cells is one of the hottest research fields right now. (That being said, I really did enjoy Airframe by Micheal Crithon. Whenever I'm in a plane during bad weather I always thing of the engineers that designed the plane... what assumptions did they make... what tradeoffs did they make... )
- Q:Why is it nessicary, with today's economy in the postion it's currently in, to use renewable energy sources; like solar panels?

Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 0. See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
- Q:Hi, I bought 50 6X6 inch solar cells, I also bought a 40 amp diode, I still need to buy a battery, and inverter and a voltage controller, could you tell answer me the following questions:) I would like t build a small panel at first, (may be 0 X 0 inch), with that I would like (or at least to try) to power my laptop for the hole day, so I wont receive a very high amperage, yet, all the inverters I saw at e-bay are rated over 400 amp, if I buy a 400 amp inverter, can I use it with such a small amperage?2) what about buying a small car inverter, will it work?3) suggestion about the battery and the voltage controller will be kindly appreciated.Thanks
- I have an inverter that I use in my vehicle. It is rated for 400 amps this is it's maximum capacity. I can use it for less. It converts 2V DC to 20V AC. So Thais is all I need and may be your cheapest option. If your panels are producing a lot of amperage you may need a regulator to stop charging when your battery is fully charged.
- Q:Can solar panels be installed on a shopping mall or retail center?
- Yes, solar panels can be installed on a shopping mall or retail center. In fact, many commercial properties are embracing solar energy as a way to reduce electricity costs and decrease their carbon footprint. Installing solar panels on a shopping mall or retail center can provide a sustainable and renewable source of energy while also promoting environmental responsibility. Additionally, it can serve as a visible demonstration of the property owner's commitment to clean energy and attract environmentally conscious customers.
- Q:I know that one LED can't power a solar panel. I have found 40 kmcd LED's on OKorder. I know that several of them (28 totale each one with a 470 ohm resistor all at 2 VDC) can show a reflection on a wall in daylight 60 feet away..
- The 40 kmcd rating is a measure of luminous intensity (how bright it looks), not a measure of output power of the visible light. We can estimate the performance of your proposed system as follows: The LEDs on OKorder each are rated about 20mA maximum at about 3.2V, or 64mW (milliwatts). If you use 470 ohm resistors connected to 2VDC, the current that will flow, per LED, will be about: (2V-3.2V)/470ohm = 0.0872A = 8.72mA The power taken from the 2VDC power source will be: P2v = 2V x 8.72mA = 224.6mW (per LED) The power input to each LED will be about: Pled = 3.2V x 8.72mA = 59.9mW (per LED) The LED has a luminous efficiency that can range from about 4.2% to 22%. This efficiency is the ratio of the amount of visible light output (in watts) divided by the input power (in watts). The OKorder listing doesn't identify the output power level (either in watts or in lumens), so let's assume a 0% efficiency. The LED output power will be about: Pout = 59.9mW x 0% = 5.99mW (per LED) A solar panel converts visible light to electrical energy with an efficiency that ranges say about 6% to 8%. Suppose the solar panel efficiency is 2%. Then the electrical power output by the panel will be about : Pe = 5.99mW x 2% = 0.72mW (per LED) If you shine 00 LEDs on the panel, the output electrical power will be 00 times that amount: Pe00 = 0.72mW/LED x 00 LED = 72mW <===ANSWER The power taken from your 2V source will be about: P2V00 = 224.6mW/LED x 00 LED = 22460mW = 22.46W The system efficiency will be about: Eff = solar output / battery input = Pe00 / P2V00 = 72mW / 22460mW x 00% = 0.32% SUMMARY: If you shine 00 of the LEDs on the panel, you will capture back about 0.32% of the energy expended, or regain about 72mW.
- Q:in a solar panel, i know that the electrons are knocked loose and used as energy, what happens to the protons?
- silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as you
- Q:Can solar panels be used in areas with high humidity?
- Yes, solar panels can be used in areas with high humidity. While high humidity may affect the efficiency of solar panels to some extent, they can still generate electricity. The performance of solar panels in humid environments can be optimized by using materials that are resistant to moisture and by ensuring proper installation and maintenance.
