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: I know absolutely nothing about electronics but have a lot of money. I am thinking of buying the Sunforce 3730 30W monocrystalline solar panel (the best I could find that was that size or smaller). What would be a good battery to go with it? I am thinking of buying a 2V Concorde Sun Xtender (again, the best I could find). But how many batteries will I need? I want enough batteries that it would take the solar panel 2 days to completely charge them from empty (bearing in mind the unavoidable inefficiencies like cloudiness/changing sun angles). Also, what other stuff would I need, like I hear something about a quot;charge controllerquot;? Any suggestions would be appreciated.
How many batteries you will need depends on what you are planning to do with them which you did not mention? Sunforce makes a 30 amp charge controller part no. 60033
Q: I have seen DIY software which explains everything for novices. Specifically, how to build your own solar panels and tie them into your home electrical system for about $00 in parts.Has anyone tried doing this? Was it easy?
The output of this system will be very small, but it is a staring point. You should consider solar water heating as a way to save on your energy bills. Heating your water accounts for about 25% of your energy use. If you can cut that by 75%, you will save a lot of money. Depending on where you are and how many are in your household, it may cost about $5000 for a do-it-yourself installation. There are tax incentives available that could potentially pay for as much as half of the system. These systems can pay for them selves in as little as 4 - 5 years.
Q: For example, how many large solar panels would you need to operate a greenhouse with lighting for simulate sun during cloudy weather, a scheduled sprinkle system and other such things?I'm looking for a very in depth answer.
if you are talking electrical solar panels, they are rated in watts they generate in full sun. usually these panels are used in tandem with batteries, so they charge up during the day and the batteries hold a reserve of power for later use. If you figure 8 hours of useful sunlight per day, then a 40 watt panel will light a 40 watt bulb for 8 hours. you can also measure capacity in watt-hours. this would be 40x8 = 320 watt-hours. the general method is to determine how much electricity demand you have over a 24 hour period to get the total watt-hours. then divide that by the watt-hour capacity of one panel to get the number of panels needed.
Q: Can anyone tell me how to connect a solar panel from a calculator to a motor from an RC car.
Connecting them is not a problem: the solar cell has two leads or terminals, and so does the motor. The problem is that the panel from the calculator cannot supply very much current, and you need quite a bit for the motor. Also, the voltage is probably not more than 3 volts, and the motor needs probably six to twelve volts. If you have a voltmeter, check the output from the solar cell. You can get solar cells that will put out more current, but they will be bigger than the ones used for calculators. Even with these, you will probably need several in series to get enough voltage for the motor.
Q: what is the average cost, for a single family home, to install solar panels? I live in CA.
Just to be sure - when you say solar panels - are you thinking of hot water or electricity? For electrical power the system must photovoltaic.
Q: where can i get some solar panels for a camper trailer
There are many suppliers for solar panels. Try camping shops, BQ or other leisure shops. Alternatively try one of the companies listed here:
Q: I have seen quite a few different websites that talk about building your own solar panels for around $200. I wanted to know if anyone has had any experience with this before I decide to try it myself. It would be very helpful to know what I can expect from such an inexpensive setup; what kind of electronics or appliances would I be able to power. Realistically what can I expect from a $200 setup, and what would I need to power say a whole bedroom (clock, regular sized TV, PC, ext.).
Scam. okorder / Many of the other review sites are fakes to steer people into buying.
Q: How much space is required to install solar panels?
The amount of space required to install solar panels varies depending on several factors, including the size and capacity of the panels, the energy needs of the property, and the available sunlight. On average, a typical residential solar panel system requires about 100-400 square feet of roof space per kilowatt of installed capacity. However, ground-mounted systems can also be installed if there is enough space available on the property. It is recommended to consult with a solar installer to assess the specific space requirements for a particular installation.
Q: Is this true in a dc system? What if my battery current is negative?
complex task. browse in google and yahoo. that could help!
