Q:Do it yourself Solar Panels?
sure, but if you don't know what you are doing you could really hurt or kill yourself. Basically you can do whatever you want on your side of the power meter and in the rare occurrence when your solar panels are producing more power that your home is using the meter will run backwards and you will be feeding power to the grid and theoretically reducing your power bill. At the very least you will be using less power from the grid
Q:How to connect or use Solar Power Panels?
You will need help with this. Panels may or may not be 24 volt. If you can find a name tag, you can find out from the manufacturer's web site. Some folks hook them all in parallel. Mine are in series, to create 480 volts. the reason for going to higher voltage is to reduce power loss in the wiring. Even then, I used a wire size larger than recommended. The frames want to be interconnected, and wired to ground. The live conductors connect through disconnect switches to an inverter. The inverter is sized to the output of the panels. Where the utility allows net metering, the inverters are connected through a disconnect switch to the grid, which of course also feeds the house. Assuming you are on the grid, you will not need batteries. If outages severely impact you, you can have batteries. Counting against them is that they are costly, and use part of the power you generate, just to keep them charged. If you have batteries, it is usually best to rewire circuits so noncritical circuits are disconnected during outages. Leaving perhaps minimal lighting, fridge, freezer and critical medical circuits. Learn all you can from the Internet (try solar panels), and from the green search box above. Be sure to see if your state has a rebate program, and the conditions which it requires.
Q:0W solar panel can use on what?
Graham is on the right track. However, you need to factor in a 80% DC to AC conversion loss. But yes a 0W CFL is about the size of it... Harbor Freight sells a system consisting of panels, battery, inverter, and TWO CFL's for $250. (You can power 2 CFL's off the grid for a very long time for $250)
Q:i am asking about the solar panels?
First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
Q:where to find used solar panels?
That's not a good idea. Solar panels wear out, and you probably won't know how worn out they are until you buy them and install them. Which is a little bit too late for most refunds. Your best bet if you're dead set on being foolish, is probably some place like craigslist.
Q:how much money does solar panels save?
What you are really looking for is ROI. Return on investment. If you spend 0K up front how long will it take to recoup that 0k. The answer is too long. Solar panels are not and never have been about saving money. They are about trying to save the planet. So if your school wants to go green then they should do it but the overall cost will be higher.
Q:Solar Panels in Abu Dhabi, UAE?
I know where in Dubai , just go to Naif road where they sell the satellite equipment , there are a couple of shops that sell all kind of solar panels and dish equipment stuff. Sorry can't remember the name, But it is right in front of the paid parking lot (the private not public one).
Q:solar panel questions.....................?
No don't do that unless you want a fire or worse electricution . DO NOT PLUG INTO THE WALL . st solar panel 2nd regulator 3rd 2 volt battery 4th inverter . The inverter should have 0 volt terminals that look like the plug on the wall . You would plug your TV or light into that the inverter . You would need an electrition to hook into your home electrical system . They will hook up a device made to tie into the grid or your meter that will make it run backwards but it takes alot of solar panels too do that . Please do not plug into wall .
Q:How can I regulate current from a solar panel?
If you want to energy each USB ports on the identical times, It could not be possibble. Your sun panel best provides 2.24 Watts (20V * 0.2A) of energy and you ought to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses out of your regulator(s), you are going to be method over your vigor finances. You'll want extra of a sun panel or less of a load.
Q:hi i am asking about the life of solar panels?
For mono-crystalline solar panels, most warranties guarantee 90% of the original efficiency when the panel has been used for 0 years, and they guarantee 80% of the original efficiency after 25 years of use. If the original efficiency is 5%, the efficiency after 0 years of use should be 3.5%, and the efficiency after 25 years of use should be 2%. Some people believe that the actual average rate of efficiency loss is slower than that. You might retain 85% of the original efficiency after 25 years, making the average efficiency drop about 0.6% per year. After 75 years, a solar panel that was originally 5% efficient might still be about 8% efficient.
