Q:how can i build a solar panel?
Have okorder.com . This can surely guide anyone!
Q:Can cold light make solar panels power
light - heat - dynamic - electric conversion method through the use of solar radiation generated by thermal power, usually by the solar collector will absorb the heat energy into the refrigerant, and then drive the turbine power generation. The latter process is the light-heat transfer process; the latter process is the heat-to-conversion process, which is the same as the conventional thermal power generation.
Q:Solar panels.......Earning potential.?
it depends on your solar panel, but you can sure supply most if all of your electronics and electric stuff in your house on a sunny day. If you want to know exactly how much power it supplies and how much $$ you can save you simply have to calculate how much power your home consumes per day/month. I know of people totally reliable on solar power for their home and I too will put solar panels on my home one day.
Q:Why don't scientists use the design of a tree for solar panels?
I don't know much about solar power. This does however seem to be a very interesting idea. But I'd imagine that the complexity of building such a structure would be far more difficult that just laying thousands of large panels in an area. The shadow from higher panels may also have an adverse affect on the lower panels. Consider the tiny panels that do provide energy and compare them to a large panel that is easier to make.
Q:Is this a good kit for building a solar panel?
i like Eric's answer. that is conceivable to construct your man or woman panels via wiring mutually man or woman photograph voltaic cells. that is an exciting element of do, yet isn't a thank you to save money. in view that such panels are unlawful to hook up with the grid, you could result making use of them with batteries, and paying extra for electrical energy than in simple terms paying for it from the electrical powered company. photograph voltaic can ultimately save money, yet to do this, you often spend the equivalent of five, 0, possibly 5 years of electric expenses up front, then have decreased or close to-0 expenses thereafter. once you're obtainable, truthfully look into installation extra insulation and weatherproofing on your place. you additionally can evaluate paying for and installation a photograph voltaic water heater.
Q:Does anyone know a good company to buy solar panels from?
a few months ago there was an article in pop sci about a company that has started to make solar panels at a fraction of the cost of what they used to be by using a printing style process instead of glass panel style they should hit the mass market soon that would be the best bet for a starting point to beat out price problems to allow a competitive edge they also had a article for low wind high power residential windmills for that could help in the alternative fuel push
Q:What makes solar panels Inneficient?
Solar panels produce very little heat or sound compared to electrical energy. In terms of the sunlight striking the panels, solar panels have an extremely poor efficiency because they can't possibly absorb 00% of the light energy. Solar panel efficiency is usually given is terms of converting the light that IS absorbed into electricity. Improvements are happening constantly. Mainly, trying to maximize electrical conductivity.
Q:solar panel, dc light help?
You can't really judge the watts for solar lighting the same way you could for dc lighting. This is because of several factors The lights that you showed ARE NOT high quality lights and furthermore; they are not a well-known brand. Also, I would be suspicious of any store that offers lights for less than half of what other stores do. They are dumping the merchandise, which means it could have been sitting around for a while. MAXSA Innovations makes good solar lamps, so does Solar Goes Green. As the other responder wrote, you are better off using dedicated solar spot lights or floodlights than trying to integrate a solar panel into regular solar lights. A 00 Watt solar panel is pretty strong, and you also would need a battery. Unless you know how to rig up the system with appropriate controllers to make sure too much energy doesn't get into the rechargeable battery (lithium ion or NiMH), you take a risk on having the whole system fry out.
Q:Benefits of Solar Panels?
There's a few different kinds of solar panels. Some of them are only for collecting heat, they're relatively inexpensive and not a bad deal, though installation can be expensive of course. The most sophisticated of these use some pretty high tech collectors to heat up an antifreeze solution that in turn is circulated through a reservoir (how water heater), to supply the house. Your electric producing solar panels are more expensive. You can go on OKorder and do a search on photovoltaic panels and get a pretty good idea real quick. The panels alone can run you 2 or 3 bucks a watt of output or more, and you may need 3 or 4 thousand watts of output to give you reasonable system for your house, depending on how much electricity you use. Then there's installation, for which you may need a professional electrician and so on. If you want a system incorporating deep cycle batteries then that's another expense, but you don't necessarily need those if you're not planning to take yourself completely off the grid. Not that the systems are really complicated. Some people wire panels together themselves from scrap cell components to save money. Of course you'd need to understand the basic wiring involved for that, and you'd almost certainly be required to retain an electrician to tie any system into the grid itself. Although there is such a thing as a plug in grid tie inverter. This is is a gadget that will take your DC solar panel output and feed it into the standard wiring of your house via an ordinary electrical outlet. You'd still need to understand enough to get the DC voltage right no doubt.
Q:Does a 50W solar panel generate 540kWh?
running six hours a day doesn't mean much. You need to look at the solar insulation charts for your school's geographical location to come up with a better factor. The easiest number for you to use is sun hours. For example, Washington DC averages 4.23 hours. Do a Yahoo search for sun hours and you should find lots of charts. Solar panels rated at 50W give this output at full sun near noon at full brightness (no clouds). The sun hour factor makes it easy to find the equivalent number of full brightness hours. So, using Washington DC as an example you have: 000 panels * 50W * 4.23 sunhours/day = 634kWh a day on average. You state your school uses 88240kWh/month which is 6274kWh a day. This would mean you need ten times more solar panels since there is no way to get more daylight. Be careful to put in all the units in your formula and cancel them out to make sure you don't end up with a nonsense result. The title of the question would be answered as followed: 50W/000 * 4.23 sunhours/day = 0.63kWh/day or 9kWh per month or 228kWh a year. These are annual averages. If you wanted a specific month, you would need the sun hours for that month. Hope this helps.
