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: How long does it take to recoup the investment in solar panels?: The time it takes to recoup the investment in solar panels varies depending on several factors, such as the cost of the panels, the amount of energy they generate, the electricity rates, and any available incentives or tax credits. On average, it can take anywhere from 5 to 15 years to recover the initial investment. However, with decreasing panel costs and increasing energy savings, the payback period is becoming shorter, making solar panels a more attractive and financially viable option for many homeowners and businesses.

Q: I'm just geting into electonics and stuff. So I am trying to make a simple USB charger. I'm looking for at least 4 volts output. What I've got is two solar panels (detached) a 4 AA battery holder, and a circuit board with an led on it (took the solar panels out of old lawn lights. I need more charge out of my panels (I think) so I tried attaching them. I soldered the positive wire from one to the positive connection on the other and negative wire to negative connection. After doing so and checking the multimeter, it says I have no output at all. How do you connect them?: You have to look at the power output of the cell. The first consideration has to do with voltage. A single cell with no load might output one volt or less. Wiring cells in series would double that output, at least in theory. (Internal resistance will lower the actual voltage.) You've wired the cells in parallel, however. Try unsoldering one electrode and then measure voltage output of each cell. There is still the issue of current output. I don't know if there will be enough with your setup. How many cells are there and what kind of batteries were they charging?

Q: I was wondering if they create other forms of energy besides electrical that is unwanted. Like heat due to the friction of something, or sound. Also why is a solar panel not able to collect 00% of the energy that is striking its panels. And how could the efficiency of this be hypothetically improved.: figure it out for us

Q: Do solar panels require a battery backup system?: No, solar panels do not require a battery backup system, but it can be beneficial to have one for storing excess energy for use during cloudy days or at night.

Q: i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be: Depends on the size of the house and the average number of sunny days in your location, and how careful you are with your usage. Many houses too have solar panels that only provide part of the electricity needed. A medium sized house in a sunny climate might need a 4.0 kW system, which could mean6 x 250W solar panels,a roof area of 27 sq meters.The average energy use in a sunny country like Australia is 20 kW of electricity a day. To catch that much electricity on your roof you need a 4.0 kW system. In Australia you can buy reasonable quality systems for about $2 a watt (factoring in federal government rebates). This means a 4.0 kW system might cost $8,500. This is not cheap, so it makes sense to cut down your energy use first. :)

Q: Im fourteen and looking for a career I already know solar panels capture the sun and turn it into energy but i would like to know more.: light from the sun hits the atoms and excites the electrons. This knocks the electrons out of the atom and then the electrons travel in a certain direction. This is the basics of electricity... flowing electrons. And so there's your direct current. I'm sure you could find out more by googling how do solar panels work

Q: I used to live from my car and i am soon returning to that way.I want a solar panel to a battery to a surge protector so that i can use a portable wifi box and my laptop at the same time. Also i would charge my phone occasionally.I would like the charge to be enough for several days in case of cloudy weather.I just do not want anything to short circuit or ruin my laptop etc.Is thete a way to get this?What do i need or what exactly should i look into?: Actually they do make these... u have one but the voltage is no guaranteed as depends on the radiation from sunlight. I have a 8v 60Watt folding solar panel... works great and does charge laptop but not consistent. It works better when you also have an external battery with you as well. Battery will charge laptop Solar panel will charge battery Also most important... put laptop screen on super dim / power savior mode or else laptop will eat up energy. I have a desktop replacement hp laptop and able to keep it charged at 9volts just under 2amps... (38 watts)... on power save mode of course ALLPOWERS 8v 60Watt folding solar panel charger Also.... Poweradd Pilot 30000mAh multi-voltage (9v -20v) portable chargers. Remember solar panels are nothing without batteries... not just for storing at night but also storing all the energy you can get. If not you would only be powering the load

Q: I live in a higher LATITUDE so in the winter months, there is a limitation in the amount of sunlight available, but will this impediment restrict the ability of solar panels to function due to the lack of sunlight involved?: Solar panels work in sunlight, so obviously the more sunlight, the more power. However, ironically, solar panels don't like heat, so they work better in the cold. Higher altitudes often have more sunlight, due to less crud in the atmosphere, and are often colder than lower altitudes, so you will often get better performance in higher locations. We have solar systems working in every continent in the world, including near both the north and south pole.
