Q:Will a 2W, 2V mono solar panel power up a laptop battery?
I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
Q:Solar Panels in the 200 Toyota Prius?
The solar panel powers the fan in the solar-powered ventilation system. The ventilation system helps to keep your car cool while parked out in the sun. If your car is cooler, then when you get into it after parking somewhere the AC won't have to work quite so hard to get you comfy when you start your car. Less AC use means less hybrid battery use (since the hybrid battery powers the AC), which means that your gasoline engine will run less (to recharge the hybrid battery), meaning better fuel economy for you.
Q:Cost of a solar panel?
The first thing you need to do is look at the power needs of those things. Add up the power (Watts) to run all of those things at the same time. Then you're also in trouble if you plan to run those things when it's not peak sunlight, so you'll need some battery setup. And some appropriate fuses and diodes and a controller of some kind to protect your panels and the things you are powering. It would take a bit of physics and electrical knowledge to do this and do it safely. I built a car that ran off of solar energy in a college project last school year. We had a bank of Kyocera 50 Watt panels that cost 250 each. So, you won't be able to do this for under 200, sorry. If you wanted to spend more I could figure out everything you needed for you, but money will be a problem. And I don't know if it will really be cost effective.
Q:How can I make a sun tracker for a solar panel?
tbls0 has a good idea for the tracker, but let's take this one step farther. A clock motor large enough to move a solar panel, unless it is a very small one is going to be large, and expensive. Use the timer motor, as suggested, but attach a slotted disk to it, with a light source on one side, and a detector on the other side. As each slot comes up and allows light to pass through, this creates a one shot pulse which is used to cause a stepper motor to move position to keep the panel aimed at the sun. At the end of the panel travel for the end of the day, a switch could be set to close, bypassing the step control to put the motor into full constant speed reverse, this causing the panel to swing back to the morning position. The whole affair gets it's start up call by means of a light detector, similar to those used to turn lights off at sun up. The control would, of course be set to turn the system on to track the sun during the day. While some digital control is going to be needed, the system would not need a computer to run it.
Q:Which is the least expensive, yet still very efficient, type of solar panel?
Since you are asking for a rather technical answer you should be aware that solar panels come in several varieties. Two broad categories are photovoltaic panels which have achieved marketable efficiencies of around 24% and solar thermal panels which are routinely achieving efficiencies of between 60 to 80% while they are also much cheaper than photovoltaic panels. So the short answer is solar thermal panels. But what can you do with solar thermal energy. The answer is just about everything you can do with light energy. Sometimes additional equipment makes the efficiency drop to near that of photovoltaic panels. The trick is to keep the devices as simple and as efficient as possible. Solar thermal can of course be used to heat our homes. But it can also be used directly for air conditioning. The type of air conditioner uses a slightly different principal but it is one of the oldest that was once used in ice houses before refrigerators. It is known as an absorption system. At some point you may want to make electricity from the sun's heat. The most efficient commercial systems are not photovoltaic but solar thermal. There are several commercial systems where increased scale improves efficiency. The most efficient is a solar parabolic dish system combined with a stirling engine. At around 30% efficiency it beats photovoltaic and other thermal systems. At this level of commercial development, the various systems are more often described as solar collectors rather than panels.
Q:Blocking diode for solar panel?
At least a 2 amp diode. rated above the 2 volts that are commonly found on the market. A blocking diode must be able to stop a higher current and voltage than the panel maximum. A diode will work on any voltage and current lower than it rating.
Q:lighting my pond with solar panels?
You can get 6V cells and SLA batteries. You would get a panel and batteries suitable for the lights you get though. Depending on what you want to do, you shoud look into LED lighting, which is more efficient than incandescent. You do not want to drain your battery flat. Rather you want to draw only 2/3 of its capacity of so. You would find the lights you want (likely 2VDC), and add up the current they draw, and get a battery that would supply enough capacity (in AH, which is amps time hours) for a couple nights use (to account for weak solar days), and a solar panel to charge two days of use in one good day. You would use a charge controller so that the solar panel does not over charge the battery, and some sort of dusk timer to turn your lights on at dusk and off several hours later.
Q:QUestion about portable Solar Panels.. Mine is 2v?
Your portable panel is at most a few amps at 2 volts nominal.Hopefully you have a higher voltage than this to enable you to charge a 2 volt battery. This takes about 3.3-3.6 volts. Your converter will function until a battery reaches about 0.5 volts (drop out voltages vary greatly). A deep discharge marine batttery will be the best bet for storage but usually more expensive than a regular battery. If your resources are limited, you might try from these cheaper sources. Insterstate battery stores usually have blems at a lower price. These are totally functional batteries but have surface imperfections that the manufacturer doesn't want his name on. Also check you local junkyard or towing service. They are often asked by insurance carriers to junk a car which has been wrecked. Many times the batteries are still perfect. They sell these for what they can get for them. Look for one from a SUV with lots of power options. Often kids cars have outlandish stereo systems requiring heaavy current batteries. These are a good find. Consider getting a solar power management system for charging your system. It will limit your charging voltage so you do not float a 2 volt battery above 4 volts where it would slowly destroy it.
Q:Solar Panels heat absorption?
Solar panels . Are you talking about solar cells or panels ? Solar panels can be either for hot water or electricity but i take it your talking about solar cells that make electricity . Heat has nothing to do with making electricity . In fact when they heat up they give out less so its good to keep them cool . With size they give out equal amounts of volts but less amp the larger the more amp you get. Solar cells work with white light that knock the electrons around that produce electricity . To much such as putting a magnifying glass on them will burn them up but will kick out twice the volt but only for a short amount of time before they burn up . If you can keep them cool with an intense light like that im not sure what they will do but to much heat will destroy them. Edit: Yep you got that right . As far as the desert to make up for the loss of volts because of the heat they just add a few more cells . Say there going for 2 volt it takes 24 cells because each gives you /2 volt but most use around 36 cells if not more . That would give you 8 volt then a regulator regulates the amount going into the battery . Most will put 3 volt into the battery to 4 volt . Freezing temps aren't going to do a thing to them as long as the sun hits them without snow covering them . I build mine with 40 cells getting 20 volt and a bit more on some . That way if its a cloudy day i still get over 3 volt and plenty of amps .
Q:hi i am asking about the life of solar panels?
Most experts believe solar electric modules have a lifespan of at least 25 to 30 years and most manufacturers provide a warranty for this period. However, the truth is that we don't really know for sure since most modern solar panels have not been in existence that long. Many experts believe the actual number could be much higher, possibly as much as 50 years. What is very clear is that solar modules are extremely durable and lose very little of their energy generating capacity over time. From: bit.ly/tpTfK
