Q:Which is Better: DIY Solar Panel vs commercial grade solar panel?
Create okorder.com
Q:Is there anyone trying to create a cheaper and more efficient solar panel?
Solar panels are one of the hottest areas in materials research today - from basic science to applied production techniques. There have been major strides in thin-film manufacturing technique as well as silicon technology. There's not a lot of hype about it because solar panel manufacturers don''t really need to advertise yet - they are selling at factory capacity with demand for more. Standard silicon solar panels now sell for around $3 a watt, and grid parity is expected within 5 years. Reference is to the MIT Technology Newsletter, which runs several articles a month on new solar tech.
Q:solar panels for my home.?
You will first need to know how much power you'll be using. Follow the link I left and it will take you to a page that has an Electrical Load Computation Worksheet. It's about the fifth one down on the page. After that, you'll be able to figure out what you need and what it will cost. The page link I left has other helpful articles, too.
Q:A Question about Solar panels?
I am sure someone can tall you.
Q:what materials would you use and how would you construct solar panels enough to run a household?
Silica based solar cells are not the kind of thing you whomp up in you basement. Here are a couple ideas for solar systems you can build and install yourself. Take a 4 x 8 sheet of /2 inch plywood. Frame sides with 2 x 4's. Screw tin cans in a staggered row (checker board) pattern inside frame. The more cans the more heat you get so place them nearly touching. Paint cans and entire assembly flat black. Cover top with glass, plexiglass (best) or heavy mill clear plastic (cheapest)Place on roof. Drill 3-4 inch holes in opposing sides. Run pipe or tubing into house. Attach to small low speed fan. The black paint will absorb sunlight and heat. The air moving through box will carry heat into house. It's a cheap efficient way to help heat your home. You can vary size and shape of box to fit your roof. If you use more than one box, hook them up in series. More boxes mean more surface area means more heat. To heat water. Take a steel tank. A car gas tank works well. It is galvanized so it won't rust, is cheap, and easily available at any auto salvage yard. But you will have to flush in throughly to remove gasoline odor. A steel 55 gallon drum is easier to work with but may cost more. Paint exterior of tank flat black. Weld/glue/clamp water pipes to tank. Place on ground in area that gets lots of sunlight. Attach water supply to tank and route discharge pipe to house or appliance. Black painted steel absorbs heat from sun light and heats water. In spring and fall you get warm to hot water. In summer you get scalding hot water and in winter you get cold to luke warm water. Both of these solar powered systems are seasonal and their output varies according to location and climate, but they are very inexpensive and easy to build and provide FREE heat and/or hot water for many years with little or no maintainence.
Q:How does a solar panel charge controller work for batteries?
If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.
Q:WHAT ARE THE SOLAR PANELS ON POWER POLES?
I work in NJ and we started seeing them around our industrial park. I think it's probably some scam for the most part. Each panel isn't going to put out more than a few volts. Because they are so widely distributed about the only thing they might be good for is lighting a sodium bulb or something. A much more effective use if it was a serious / more efficient/effectively designed project, we'd probably be seeing farms of panels going up all over the place and on the tops of big-box buildings, but I'm not seeing alot of that.
Q:Opinions on Solar Panels?
Bing solar power in Germany. Solar power has an option of assisting in removing some of the burden during daylight, from power generation plants. Anything is a help. Plus they will continue to do it forever (at least a lifetime). But they are not the total answer. Like wind, limited to certain areas. Wave generation is another solution, but still limited to coastal areas. The current design of most supply grids does not allow transportation of power long distances. You want a real eye opener, Bing transportation line looses power grid and see how much energy is wasted, and the amount of carbon put into the air for these losses.
Q:Solar Panels?
Actually even if you cover your whole roof with panels, you wont get enugh power to even run a tv, fan and light at the same time. Solar panels give out a very less power output.
Q:can a l.e.d light power a solar panel?
While I understand Search's answer, because it was also my first reaction, am I wrong in thinking that this is some sort of science fair project, for which you need to power a solar panel indoors as though it were being illuminated by the Sun? The question at least makes sense in that context. Solar panels provide modest power even from room lighting, sometimes calculators are powered by small panels, but that is a tiny amount of current. . You'll probably do better by asking this question (a bit more clearly) over in Engineering. It's not really an Astronomy Space question, though there may be some crossover between the two groups of users. Meanwhile, while some white LEDs can be pretty dazzling to the eye, I don't know how much actual power they are pulling down compared to what you'll need the panel to generate, but I don't see why it shouldn't work. I just don't know how many LEDs you would need. . .
