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:How much maintenance do solar panels require?

Q:Building my own solar panels?
Hello, okorder.com. Look at some videos ( There are few hundred of them ) Basically though they all stay with the same idea or plan. Look at how they wire them and get more familiar with what they are running on them depending upon how much wattage panel they are running. I seen a 400 watt system costing about 600 dollars US currency. Because two 200 watt panels = 50.00 each and the diverter = 50 and the charge controller = another 50.00 at the least. Then you have wiring and some deep cycle 2 or 6 volt batteries to loop up which is extra cost if none laying around to use. Check-out youtube though for the best advice and opinion you can give yourself then maybe look at a few solar panel websites which sell Solar kits for some more price ideas. To run a laptop i assume you will need atleast 400 watts and 2 to 4 ,twelve volt batteries which are deep cycle and it might take 3 to 5 days to charge up your batteries but they should charge laptop battery no problem without much loss if you keep laptop charged often. TV is power hungry and you will need something like a $500.00 system for that. 000 watts etc. Tv just drains the battery bank way too fast. So to answer your question about what you can get for 200 bucks. Maybe a 80 watt kit system for about 250 bucks complete except batteries. with 80 watts you could power some cool nighttime night lighting with super bright LEDS or LED light strips which are about 0.3 watts per LED or 5 watt LED cabinet lights work well So for a 80 watt system you probably only want one 2 volt battery or else will take alot longer to charge on such low wattage. But you could run LED lighting for nighttime lighting and easily save 250 dollars in a year off your bill by charging phone from it, using LED lights and other low wattage devices if utilized daily. Just don't draw more power than it makes and it should be ok. Goodluck with your research.

Q:What kind of batteries to use for a solar panel?
Deep cycle, Golf Cart Batteries. You can get them at a battery store.
Q:How I can get 300- 500 Wh of energy using Solar Panel?
As in the reply to the other version of your question - you should be able to get that wattage much of the time during full daylight from the area you specify, but your location, weather, and ability to mount the panel(s) at the best angle to the sun at time you most need the energy (winter? summer?) Instead of going with guess work on the efficiency of the panels you are considering, the people who want to sell you panels (or their website) should be able to tell you from the angle of your mount (roof?) and location, etc., an estimate of the average and maximum power available and the kWH during various seasons. This has to be known for either buying the batteries for storage or knowing the economics of feeding back into the grid, depending on the method used.
Q:How solar panels and furnaces work?
Well solar panels conduct electricity from the suns waves and turns it into dc current then it is either put into a grid tie inverter to change it to AC and it makes you meter go backwards instead of forwards. or if its not a grid tie inverter it is just put into batteries as dc then changed into AC from the inverter and then used for household appliances. nothing really does run on DC that is why it has to be changed. and for solar furnaces if you mean a water heater that works by a substance here in Pa its antifreeze is heated up by the sun in the panel it is in a continous loop and that is what gets heated up the water then flows over tow of the tube that contains what ever substance such as antifreeze and heats the water.were the water and the tube that changes the water from cold to hot is called the heat exchanger. the substance is actually get heated first then the water. solar heating for water accounts for 29% of water heating in the us. Now if you mean solar furnace as in passive solar thats completely different because here in Pa if we want it our houses have to face to south to get the suns rays. (alot more windows) and there is a cement slab placed only on the south side of the house and it has insulation covering it. There is a certain type of glass that is used for this that will allow the suns rays to come in and let the heat in for the summer and also for the winter. the main place for that would mostly be the first floor of the house due to the height of the windows and the angle of the sun(pa in the summer is 73 degrees and in the winter its 27 degrees) thats when the second floor would be ok to heat the rooms. Hopefully i helped and i explained it in a way that you can understand.
Q:question about solar panels....?
Not many people realise it, but Einstein did not win the Nobel Prize for either Theory of Relativity. He was awarded the prize for his work on the photoelectric effect. i.e. the ability of some materials to take photons of light and turn their energy into electricity. Now, since most of the Sun's UV rays are filtered out by the Earth's atmosphere, else we'd be able to get a sunburn in seconds walking around outside in daylight, I think there is some energy imparted to the solar cells by UV wavelengths of light, but most solar cell materials rely on the wavelengths of electromagnetic radiation we call visible. Plus, I always thought infrared wavelengths conveyed more heat energy than UV rays.
Q:what is one benifit in a solar panel?
what do you want to know ? there is so many benefit of the solar panel , such as no pollution , ETC
Q:how much do solar panels cost and r thay worth buying?
If you are looking into a credit or buy back of hydro, you should be inquiring about windpower not solar...you will have better luck creating more with that than panels. It is not so much the cost of the panels that is a lot, it is the cost of everything else you will need to use/store the power....inverter, batteries...etc
