Q:how can i build my own, cheap, solar panels at home?
The idea behind building your own was to get defective and broken solar cells from the manufacturer, preferably for free though many now charge for them. These are cells that are either cosmetically blemished, cracked or otherwise broken during manufacturing and transportation. As each cell fragment could have very different voltage and current characteristics, you have to manually measure the voltage and current characteristics, sort them and then wire them in parallel or in serial to achieve the desired voltage and current characteristics for the panel. Wiring in parallel increases the current while wiring in series increases the voltage, the current capacity of cells in series will be that of the lowest current capacity cell in that series hence you need to match fragments up to wire in parallel till you have enough current capacity to participate as a cell in the series. Cell fragments can only be wired in parallel if they have the same voltage output. It's painstaking work and it's difficult to place all the irregular shaped cells onto the solar panel in a layout that efficiently uses the space so your solar panels will likely be much larger than commercial ones. You could augment them with Fresnel lenses since the cells don't occupy as much of the available surface area hence focusing the light onto the cells rather than the board will help with efficiency. Practice your soldering skills cause you don't want to have to go back in to figure out where that cold solder joint is. If you're real lucky you can get a supply of blemished cells but the cheapest ones are the broken cells.
Q:Where to buy cheap solar panels?
Grimcho..I'm going to give you a secret that no-one I know of has ever spoken of..Call Your local railroad maintenance yard and/or your local oil production company..I know your probably in another part of the world where this will not apply but here its like this.. BNSF changes out every 2-5 years their 00w 24v panels...they still have a good 5years of lifetime..Oil companies change them out on their well sites every 2 years 2x 60w 24v (actually they are 2 +2vdc grids series) now if your in Italy sorry this didn't work but if your in New Mexico ..they are in Santa FE...also they have way good batteries that are wet cell and run about 600$ each that they just dump many times on the guy for asking..try it....From the E....
Q:Which stores can you buy solar panels at?
This one.
Q:Any tips for protecting my solar panel from high winds?
You have to make the decision weather you want it portable or stationary. If you want stationary I would make some good brackets for them / search for cheap ones on OKorder. I'd have to see them to be able to offer any better suggestions. It's always hard to decide so you'll have to take notes and do research.
Q:i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
Wow I think that your battery are too big or in othercase your solar system panels are too small. But making some calcs if you connect your panels in parallel you will have 30 Amps of Recharge for your batteries. Assuming that your batteries are discharged to .75 V/C you will need at least (. x Ah removed)/Recharge Amps = (. x 550Ah)/30A, that means that you will need 20 Hours to recharge your batteries Literally this is imposible to have fully charged your batteries for a proper application you will need 65 Amps from your panels to recharge your batts in 4 hours or de-rate your batteries to 00 Ah
Q:Solar Panels, anyone?
Unless you live in an area with a very high UV index, like Las Vegas for example, solar panels are not cost-effective. You definatly should not attempt to install solar power yourself if you intend to power a residence with it (unless you live in a shack). A certified electrician is required in order to connect your equipment to your house's electrical system. It isnt just as simple as a few panels. You need a converter that turns the DC voltage generated into AC. You also need equipment to connect to the metering system for your house. If you want to see if it is cost effective, you will need your electric bills that show usage for a year and the price per kWH. There are a lot of websites that have calculators for solar power systems.
Q:How much do solar panels cost?
Solar panels typically cost in the range of 8 to 0 dollars per kilowatt of power they are capable of providing. That same kilowatt of power costs in the range of 8 to 0 cents normally. This is the reason solar is not all that viable, without government incentives. The person who responded You're looking at $0,000 to $40,000... is so far off the real answer as to not even be funny. I suspect a solar pv system for a school would start in the $400,000 to $500,000 range. Many areas though have incentives, which will reduce the actual out of pocket costs (but not to $0k).
Q:Why aren't electronics made with solar panels?
Cost and and it would be inconvenient to the consumer in this Gotta have instant gratification society. take the amount of money you paid for your MP3 player- double it- would you still have bought it at that price? That IS what happens when you add in a 2 to 0 dollar component. Besides- the energy required for most items you cite- a solar panel makes it not portable. While you might be able to arbittrarily decide to go without an MP3 player for 24 hours, could you do it for a week? How about your cell phone? It uses more power- so go without it for 2 weeks. You still need batteries to be charged by solar panels due to one major flaw of solar panels- they do not work in the dark. So in effect all you are really doing is weighing the device down with a solar panel, and you still have not gotten away from a need for a battery. I don't know about you, but I have an MP3 player about the diameter of a 50 cent piece- where are you going to put the solar panel??? It will not have enough power to operate the device, and marginal at best for charginthe battery which would take hours instead of the minutes it takes connected to a USB port.
Q:Solar panels and your opinion?
Solar power is still an expensive way to purchase power, as of 2007, it was 38 cents per kwh while the cost of power from coal is 0.6 cents per kwh. Of course regulations have prevented new coal power stations from being built so it's really natural gas power stations at 5 cents a kwh that solar has to compete with. Solar is dropping in price but the best you can hope for is for it to reach parity with natural gas someday soon and it hasn't yet. The other issue is that you pay up front for solar power which as any economist will tell you is even more expensive and involves greater risks. However, as part of a strategy to become as self reliant as possible when you retire and have a fixed income, it's a reasonable prospect, not only will the technology become less expensive by then but at that point, fixing the price of the energy costs is more valuable than the cost of the energy. Focusing on personal finance and learning how to invest which very few people know how to do is more important right now. When you retire, hopefully you can afford to build a passive solar home with photovoltaic solar panels and wind turbines but still on the grid for efficient net metering and with a greenhouse where you can grow the staples that you need and perhaps even some biodiesel for your google driven car. Having a reasonable portfolio is really the only way to achieve that goal.
