- Q: Hello Yahoo, I am doing another one of my wacky inventions however I need something that will give me 2V of power!I don't want to connect loads of AA batteries into a battery holder as this shall run out quickly and become expensive in the long run, I don't want to carry around a big car battery either.I have been searching around on OKorder .uk and found some Solar-Powered 2V Trickle Chargers. These say they shall work on cloudy days (which is perfect as the majority of the time that is all we get!) but could I use it as an independent power source?If I attached the thing I want to run to the solar panel will it supply it with 2V of power?
- If you want to run something from a solar panel, you should remember that the power from the panel is only available when there is reasonable sunshine on the panel. Usually the solar panels are used with solar regulators in order to charge batteries. These batteries are used as energy storage for when the sun is not shining. Now, this does not mean that you cannot drive instruments directly from the solar panel and regulator. To do this, you will need a panel that has sufficient power to drive your instrument. An example is the solar powered garden or fountain pumps. I have driven 2V computer fans directly from the small solar panels - useful for cooling of things such as pool pump housings. The solar regulator is used to convert the solar panel output to a 3.5V output in order to charge lead acid batteries. I have used MPPT regulators (maximum power point tracking) which is more efficient than the standard solar regulator. If you don't use these regulators you may find the solar panel producing up to 7-9V in good sunshine which is not good for your instruments that are expecting 2-3V. Hence the answer to your question is that you will need to have a battery being charged to get useful power from the solar panels via a solar regulator.
- Q: Well I was thinking about the idea of renovating either a smaller school bus or building a tiny house and I was wondering if i can get some information on the size and watts panel should I use or more like how to get that whole solar energy in motion. Any infor and links would help
- I think that typical solar panels are 2'x4' and produce something like 800-000 wh per day. (That's 0.8 - kwh per day.) More in the summer, less in the winter, if they're aimed sort of at the sun. There are newer, more expensive panels that produce more. There are also thin film panels that are less expensive, and probably more sturdy. You then have a couple choices. In a house, you'd have an expensive inverter to connect to the utility power, so you can have power at night when your panels aren't generating anything. In a trailer, you want 2-4-6 deep cycle car batteries to store the power. Then you could have an inverter to convert that power to 20v AC, so you could use normal appliances. Or, you could buy appliances that run on 2 volts DC. Maybe a combination of both. You'll need to figure out how much power you're going to use, so you know how many panels and batteries you're going to need. The calculation is easy. Figuring out how much power you need is hard. You need deep cycle batteries because you can repeatedly charge them way up and run them way down. Ordinary batteries die fairly quickly when you do that.
- Q: Are there any health risks associated with solar panels?
- There are no direct health risks associated with solar panels. However, improper installation or maintenance may pose electrical hazards, and exposure to high temperatures or falling from heights during installation can lead to accidents. Additionally, some solar panels contain small amounts of hazardous materials, but they are tightly sealed and the risk of exposure is minimal. Overall, when installed and maintained correctly, solar panels are safe and have numerous environmental and health benefits.
- Q: I have a small marine solar panel on my boat It came with the boat. I want to make sure it is working before I connect it. With a volt meter It is only reading .2 volts dc. I would think it should be 2-5 volts?
- It has to be facing the sun for full power U check at the battery and it should increase as the sun hits directly on it. U can't check it at the panel after the diode.
- Q: Can solar panels be installed on agricultural land?
- Yes, solar panels can be installed on agricultural land. In fact, it is a common practice to utilize agricultural land for solar energy projects. This dual use of land allows farmers to generate additional income from leasing their land for solar panel installations while continuing their agricultural activities. Moreover, solar panels can provide shade to crops, reduce water evaporation, and improve overall farm sustainability.
- Q: Ok, so I've been having much success with the joule thief circuit and a LED, but i tried hooking it up to a small solar panel that can put out 2.5v on it's own, and can light up a white LED dimly by it self to the joule thief and it will not work ....my question is why? I already trouble shooted it, the circuit is not the problem, is it the amount of amps the small solar panel is capable of? not enough?
- Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
- Q: Let's say I can buy solar panels for my business for $5,000 and my payback period is 8 years. Would it be correct to assume that my money is best spent elsewhere (such as paying down debt) if I am being charged an interest rate of 3.9%?
- Without doing any calculations, I would assume that paying down debt would be a better use of your money. Solar panels are only going to get less expensive and more efficient with time so waiting before you invest in solar panels is a good idea. Of course, to properly evaluate the prospects of going solar, you should consider the tax credits available in your state and the promotional value to your business.
- Q: Solar panels single crystal and double crystal in the rain which is easy to use
- At present, monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
- Q: can solar panels be on houses? malls?stores? WHAT ABOUT TRAINS?
- Solar panels are an device that convert sun energy directly into electicity by photovoltaic effect,which is an physic and chemical phenomenon.solar panel can provide power for your home electical appliance instead of using electicity.
- Q: im doin a science experiment and i have a battery that is 3.6 volts , does it matter wut voltage the solar panel that im connecting it to is . Does it need to match , be less or does voltage have no effect . If so wut does matter when choosing the type of solar panel to power a bettery?
- You really need a little more infomation about your battery. It should have a recommended range of charging current. You should not exceed that range. Your solar cells must be a higher voltage than the battery, but you should not connect the cells directly to the battery. First, you need a diode in the line to keep the battery from draining into the solar cells when there is no light. Second, you need a resistor to limit the charging current. You have a 3.6v battery. Let's say the charging current is 0.A. Use a 5v solar cell and silicon diode. The diode will drop the cell voltage to 4.3v. The voltage across the resistor will be .7v for .A current, you need a 7-ohm resistor.
