Q:A couple questions about home made solar panels?
Earth4Energy okorder.com/
Q:How do you make your own solar panels?
if you're hoping to put 'em on your house and use 'em to supplement power from the grid, then you'll want to buy them. the panels have to be made with exotic chemicals, in a clean environment, with dangerous chemicals. anyone who tells you that you can make 'em yourself will be asking for money for the plans. in truth, you could get an old panel, and, if it was the right voltage, you could use it to charge your rechargeable batteries. typically, that's not the hoped for application. and, to get enough power for you house, you're not going to be able to do it yourself. whenever you buy anything, make sure you know what it can do. ie, read the fine print. if it's a few hundred (or thousand) dollars, it's not going to be useful to augment your home power. in addition to the strength, there's also the equipment that's needed to sync it up with the power from the utility, and that's neither cheap, nor a do-it-yourself project. i've seen lots of panels but when you read the specs, they're pretty useless. not good for battery charging, not for hooking up to your house. in other words, interesting projects with no practical use.
Q:what colour can solar panels be ?
Panels can come in a selection of colors, and trimmed in a variety of frames. Most are dark, black, blue or reddish in hue. Concentrators may appear white from a distance. Kinetic back up is possible in the form of a flywheel. Not very common but it is out there. Another form of kinetic backup that is used by some power companies is hydro. When the sun is out and the system is producing more than is used, the excess can be used to pump water uphill to a holding tank. Then when there is a demand, the water is allowed to flow back down turning a turbine to generate electricity.
Q:rooftop pool solar panel leaks?
Depending on the material and operating temperature of the panel, it MAY be possible to fix it very simply and easily by applying Hot Glue Gun adhesive over the cracked area. The high temperature glue gun adhesive melts at approximately 60 degrees Farenheit, and if the collector temperature does not quite reach, or exceed that operating temperature, then that repair method should work. Another possibility is an aerosol spray can product called LeakEnder. This is usually available at your local hardware store, or the major home improvement centers [like Lowe's, Sutherland's, Home Depot, McCoy's, etc.]. After preparing the area to be patched by cleaning, you just spray the LeakEnder patching material on the crack and an eighth of an inch or so around. IF the operating pressure or the collector is very low, it MAY even be possible to patch the leak with nothing more than a narrow strip of DUCT TAPE!!!!! Another possibility, but unless carefully accomplished is to weld the crack with a Soldering Gun and some scrap plastic from packaging material. The problem with this fix is that you must be very experienced in application of heat from the Soldering Gun, OR you will melt a larger hole in the collector tube than the crack was. Regardless of patching method, it is CRITICAL that the cracked area to be patched MUST be CLEAN and DRY BEFORE applying any patching material. Good luck!
Q:Need help with a solar panel?
In order: .  Just about any wire will do.  You can handle 50 mA over just about anything, even 28 gauge telephone wire.  Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.  You need a diode.  If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.  The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.  You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.  This gives you maximum current output from your panel.
Q:Solar Panels ????????
You will need many more to do any good.
Q:How do passive trackers work (for solar panels)?
It appears to be relying upon a phase change of liquid to gas to liquid to balance the system and return it to the east in the morning.
Q:How much do solar panels cost?
I have a coworker that did her home with a 5 kw system with batteries and whole house inverter. It cost $55k before the Florida $20k rebate. She sells back to the grid, but the system will not pay for itself for at least 20 years. It will not run the air conditioning, either. The batteries will give 3 days power for everything else without sun. There are companies trying to lease solar equipment, but none seem ready for prime time, yet. I've been to Sun-Electric (Venetian Causeway across from the Herald building) in Miami to buy surplus panels. They have a whole roof of panels and sell back to the grid, but they also have a room with batteries and an inverter and close shop at night.
Q:how effective & efficient are home made solar panels?
I had a system installed recently, so I would suggest starting by getting a quote from a licensed contractor. Even if you are planning on doing the installation yourself, a contractor will have a lot of useful info. I got 3 quotes and they were all about the same cost. I was able to get a 2 year usage history from our utility so the contractors were able to suggest a system based on that. They were able to tell me about rebates and tax credits, were the best location would be and the estimated amount of production. They have a nifty gadget that can tell if there will be any shade cast on the roof at any time during the year. I decided to maximize my rebates and got a system that reduced my utility bill by about 50%, although my production has cut it much more than that, my highest electric bill was $35, and that was in Dec. with cloudy short days. I got a $0K rebate and a $2K tax credit. This year the fed. tax credit is 30% of the total installed price. My system cost $26K, I paid $6K out of pocket and I'm saving about $2K per year.
Q:how the energy of solar panel measure?
A solar panel is made up of solar cells. Each cell produces about 0.5 to 0.6 volts. Cells are connected in series, like the batteries in a flashlight. Enough cells are placed in series to produce the desired voltage. Cells produce very little current, so many strings of cells are connected in parallel to produce sufficient current. The output is direct current (DC), like that from a battery. A home solar system needs alternating current (AC), so an inverter is used to change from DC to AC. Some systems have batteries for backup power. In these some of the DC output is used to keep the batteries charged. Systems are measured in kilowatts. System sizes are chosen to meet the demands for electricity. My system has a 6 kilowatt (kW) rating. The true output is more like 4. Now that you know this much you can Google SOLAR SYSTEMS to learn more.
