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:Battery for 2V .5W solar panel?
.5 Watt Solar Panel
Q:thermodynamic question that includes heating water with solar panels?
Here's a typical 4' x 8' collector rating. 40 degree latitude would be a cool climate, so you look at row D, water heating in a cool climate. Probably take the middle rating, mildly sunny day, and it is 0,000BTU per panel per day (it's 9,000 on a sunny day). 38,700 BTU / 0,000 BTU = 3.87, they'd need about 3 to 4 panels. If you used the sunny day number, you'd only need 2, but 3 is more realistic, as it is not always a sunny day.
Q:Solar panels...??? HELP!?
Solar panels are primarily used to make electricity. What you choose to do with this power is up to you. New solar technology now looks to give the panels more than this one task. For example; - solar panels made into the shape of roof tiles can also be used for roofing. - thin film solar is being developed to add to cars and other mobile devices to provide portable DIY energy
Q:What does it mean when a solar panel is 50 watts?
Volts x amps = watts, so depending on what you want to run or charge will have to be taken into consideration. For example if you have a 0 volt TV @ 2 amps, then you're going to need 220 watts to power that. Best way to find out what it's volts and amps are, is to look on the back of the TV. But for batteries it doesn't matter, cause all batteries are is stored power, that can be later used, just use an inverter on them to convert DC to AC, also use a charger controller between the solar panels and the battery, cause you don't want the Solar panels to overcharge your battery and totally **** it up ______________________________________ But the more watts, the faster the power is returned; less watts, longer times. .
Q:what are the parts of a solar panel?
Great answer Bill, I am just going to add aluminum frame and plastic clear cover on top of cells. The reason I am adding this is because after all this is installed then we have solar panel. Which as new looks and performs great but after a little while needs to be maintained. All factory warranties require solar panels maintenance to keep the warranty and optimum performance.
Q:Question about home solar panel systems?
The $25,520 price amounts to about $8.5 a watt which is high, I would've expected between $2.50 to $5 a watt and those are dated prices so it sound like the vendor is raking the price up. You didn't mention how many months your $75 financing is for but keep in mind that at 3 kw for 8 hours a day for 30 days at 2 cents per kwh, you would generate $86.40 so you will be paying about twice as much for your solar power as you would had you bought the power from the grid. Mind you, for people on a fixed income, there is the security that the cost will not rise ( if properly insured ) so there could be an advantage to paying a premium for your power if you're on a fixed income. I'd say it's a rip off but I also believe solar has a ways to go even with subsidies before it's an economic choice and that's usually not a popular stance with the green washed crowds.
Q:What does it mean when a solar panel is 00w?
The 00w panel puts out 00w at peak power -- full sun. You will lose some power as heat through wires and other equipment and also some will be lost when it's converted to AC, unless you will be using all DC appliances and lights, etc. I think a good estimate would be about 0 - 5% loss. You will also need to know your average solar insolation, average amount of full sun you receive at your site. This will tell you how many panels of 00w it will take to get you 5kwh/day. Don't forget your losses as per above and add a little extra for peak usage that is needed when two or more major appliances and power uses start at the same time. Hope this helps. I'm glad you're checking into solar and good luck.
Q:where will i find solar panel info for free?
I was looking for information about solar panels for very long time... Always got these paid websites that sell eBooks about how to build your own solar panel (I guess you are having the same problem)... Good news is that I actually found a great free resource, please see below. Hope that helps and Good Luck! Harold
Q:Question about commercial solar panels?
they are in a position to be in case you're properly knowledgeable and experienced of their assembly and working function, offered you acquire the comparable severe high quality grade cells and do perfect assembly. probability is robust although that your first a number of could be in hassle-free terms somewhat below par till you rather get the carry of it and strengthen into properly practiced purely because of the fact the pros are. Does take a important volume of grunt paintings although so determine if it rather is great use of a while or in case you will do greater beneficial to earn at your prevalent paintings and pay a professional to do this which they do superb.
