- Q:I know what they do and how they work, but at this point they're expensive, don't always produce enough electricity as needed, and can't be used when there's no sun, as in half the day. Wouldn't wind power seem so more efficient? Or if they do use solar panels, how about putting them in the desert. But I really believe that research money should go to fusion generators since that's the future and the answer to our problems. Which is best in your opinion?
- i think that they are effective, even tho they cost heaps to get installed, i think that they are worth it. They dont require any effort to operate and use natural sunlight that turns into energy that people use everyday. they may be an eye sore but think of how much they are helping the earth and they are a great alternitave to fossil fuels (which are running out anyway), the only problem that i think they would have would be in winter when there isnt much sun on a few days. but other than that they are great
- Q:If you need 9400 watts, 75 amps@ 240V, how many solar PV panels do you need?
- Create okorder
- Q:i am working on a project which requires small solar panels. i am looking for ones about 3X4. is there any way i could get these? and where?
- I bought mine from OKorder. They were from a top seller and arrived in better condition than I expected. They are 3 X 6 and have an output of .5 volts .7 watts. You will need other items as well blocking diodes, charge controllers as well as tabbing ribbon and buss wire. Learn about other components you may need at the website below. There is also an OKorder link at the bottom of the page.
- Q:Would it be possible to use a lens or a mirror to focus light onto a solar panel in order to make in more efficient? And is something like this already being used? It was just a thought and I haven't spent much time on it, but I figured I'd ask.
- yes it is being done. i've seen adds for such a system. on the other hand, if you had a 5 sq in Lens focused on a small cell, and a 5 sq in cell, they'd be about the same. in fact, the cell might be a bit better because (A) there wouldn't be any loss in the Lens, and (B) it might be that the solar cell would use some frequencies to which the Lens was opaque. in addition, the cost of solar cells is dropping, making the cost of the mirrors or lenses uneconomical by comparison.
- Q:what is solar panel? full description needed?
- Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.
- Q:Can solar panels be used for powering Wi-Fi networks?
- Yes, solar panels can be used to power Wi-Fi networks. Solar panels convert sunlight into electricity, which can then be used to power various devices, including Wi-Fi routers. This allows for the establishment of Wi-Fi networks in remote locations or areas with limited access to electricity grids. Additionally, solar-powered Wi-Fi networks are environmentally friendly and sustainable.
- Q:How efficient are the solar panels....?
- DS's solar panels convert 22% of their available energy into electrical power. This may not sound very good, but it is much better than most solar panels. Most solar panels on people's houses, for example, are fairly inefficient. Less than 4% of the energy that reaches them will be converted to electricity. DS's panels are so efficient, in fact, that unless the ion propulsion drive is running, DS is producing far more power than it needs.
- Q:Can solar panels be installed in a community or neighborhood?
- Yes, solar panels can definitely be installed in a community or neighborhood. In fact, installing solar panels at a community or neighborhood level can have several benefits. It allows for a more cost-effective approach, as the installation and maintenance expenses can be shared among multiple households. Moreover, it promotes a more sustainable and environmentally friendly energy source, reducing reliance on fossil fuels and lowering carbon emissions. Additionally, community solar projects encourage collaboration and community engagement, fostering a sense of unity and shared responsibility towards a greener future.
- Q:I have a solar panel 7.5V .25W 50mah, connect 2 in parallel to power a RC boat. The boat use to run on 6cell battery pack - 7.2V 800Mah.The dc motor requirement based on the provided battery pack, i assume would be 7.2V and rated at (7.2V * .8Amp) = 2.96 Watt.Would two of my solar panels run this DC motor ?are my calculations or understanding correct ?do lend a hand dear ''world''
- solar cells are not rated in mah, they are rated in ma or amps. I'll assume this one is 50mA. Two in parallel will give you 300mA, so that will charge a 800mA-hr battery in 800/300 = 3 hours. Theoretically, in bright sunlight if the array is exactly at right angles to the sun's rays. The problem is, depending on the type of cells, the battery pack will need 8 volts or so to charge, and your solar cells won't deliver that. If the sun is at an angle, you may get only 3-5 volts. so you have to put them in series, so you will get only 50mA out of them, which will charge the battery in 6 hours of bright sunlight. Would two of my solar panels run this DC motor ? If the motor is .8 amps, you need the battery, the arrays are not near enough. Or are you attempting to replace the battery pack with the solar array? Your english makes that difficult to understand. If so, put them in parallel to get the 300mA, but that would run the .8 amp motor very slowly. If you had 2 of the solar panels, it might run at close to full speed if the sun is bright and shining directly on all the panels. But where did you get the .8 amps for the motor? The 800Mah rating of the battery has ZERO to do with the motor current. So the answer above is based on your number, which I suspect is totally wrong. .
- Q:okay so im lookin 4 an article which explains how practical, wokable, feasible solar panels are. only positive points please :) give me the link. PLZ HELP!!!!
- Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy.
