Q: What is the main material for making solar panels?
If you make your own, in addition to buying silicon also need to buy for the packaging of silicon photovoltaic glass and EVA film.
Q: Got a quote for about $K today for solar panels to save me about $00 a month on my electric bill. I was just wondering if anyone had successfully bought and installed their own and how it worked for you?
i do no longer yet i comprehend lots on the venture. e mail for information. a great number of ppl set up them yet just to cover there electric powered warmth/air. It saves them money. i comprehend lots of people who've tiny ones exterior there window to means the lights fixtures in that one room. Its no longer an eye fixed sore the two. i stay in Canada.
Q: I need a solar panel for my laptop as i am going camping in the desert, and i need my laptop. There are two choices of solar panels, One is 0 watts and 2 V and maximum power current 0.56 amps. The other one is 2 watts, 2 V and no mention of current. My laptop plug says input 00-240V and .5A and then output 5V-5A. Which one should i get for my laptop. If there are other choices please tell me ill look them up on OKorder.Thanks
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: Can solar panels be used in areas with high pollution?
Yes, solar panels can still be used in areas with high pollution. While pollution can reduce their efficiency to some extent, solar panels can still generate electricity even in polluted areas. However, it is important to note that excessive pollution may result in a decrease in their overall performance and require more frequent maintenance to keep them clean and functioning optimally.
Q: I am interested in solar energy, but am not sure how eficiant it would be in the northwest? Any comments would be apriciated.
Are solar panels a good thing to do for the environment? - Yes. Can you recoup the cost your investment in the solar cells/panels in any reasonable amount of time in Seattle? - most likely - not. I know it's been a miserable spring in Seattle, but, I think we got 3 sunny days last month. With the number of cloudy/rainy days here, solar will only really benefit you in June, July, August and September. There are two kinds of solar panels - electric or water based. The electrics - photovoltaics - are costly to purchase and it's difficult to store the electricity once you make it. A water heater type solar panel initially cost less and can provide some benefit even on partly cloudy days. I have even seen instructions on how to build your own (if you are frugal and handy) I just do not think it's worthwhile in Seattle - if it was Denver or Phoenix we were talking about - then it would be a different story.
Q: can solar panels have glass between the panels and the sun?
As above, but also make sure the panels you use will still produce if partially shaded. Some older panels will quit producing if you so much as put your hand over a small portion of it. Newer ones don't do this but are more expensive. As you may need more panel area to produce enough energy to fill a battery (if that is how you go) make sure you have the room/roof area for additional panels.
Q: Can solar panels be used to power a train?
Yes, solar panels can be used to power a train. Solar panels can convert sunlight into electricity, which can then be used to power various electrical systems on a train, including propulsion. However, the feasibility and effectiveness of using solar panels to power a train depend on factors such as the size and efficiency of the solar panels, train energy requirements, and the availability of sunlight.
Q: i want to charge my mytouch 3g with solar panel(s) it has a 500mah 3.7v 4.4wh batterieswhat do i need to charge it can i use RadioShack 0.5W Solar Panel 4.5V or RadioShack? W Solar Panel 4.5V
see u have to make ur own ckt for this ur solar panel generate DC if u want to charge ur phine then its convenient way to harge with ur charger for this do this search for net to convert DC-AC convertor since ur charger work on AC so when ur solar panel generate DC it convert into AC that will charge ur phone in ckt u need this thing filter and amp ie the DC voltage come from solar panel 2 DC to AC convertor 3 AMP for AC 4 filter for AC and u are done....... fine ckt from google.....
Q: Can solar panels be installed on mountain huts or lodges?
Yes, solar panels can be installed on mountain huts or lodges. In fact, mountainous regions with ample sunlight can be ideal locations for solar panel installations. These panels can harness the sun's energy and convert it into electricity, providing a sustainable and reliable source of power for the huts or lodges.
Q: I am doing a school project and we need to find the cost of solar panels for our school. The problem is i don't know what size the system needs to be. Is it 000 watts or 000000 watts?Also can you find the cost of the system?Thanks
Take a look at the website from Retscreen International. This is a site sponsored by the Canadian government and they have everything that you will ever need to know about renewable energy. Download the free software and then feed in the position of your school (GPS Coordinates) and some data about energy useage. It will then link to the NASA websites to tell you the weather and work out what size of solar panel you need, what direction it should point and what angle it needs to be mounted on. I've used it for the UK, Afghanistan, Iraq, Jordan and other countries - It's brilliant - and its free. It also links to manufacturers websites and so gives you costings. Use this and you are guaranteed to be top of the class
