Q:how to connect a solar panel to a motor?
You need a battery, no solar panel is strong enough to move any significant motor
Q:Why do solar panels burn out?
They are used in an environment that's very harsh for semiconductors, especially the high temperatures. Ion migration and many other failure mechanisms increase with temperature. Thermal expansion adds its own mechanical stresses.
Q:A couple questions about home made solar panels?
there are plenty of free sites that tell you how to install your own solar panels. Just google diy solar panels. as to how many panels you need, it depends on what all you're trying to have them run.
Q:can I easily build my own solar panels for my home?
I honestly don't know but I have done lots of internet searches and there are several site where you can buy the plans to do this for around $49 and in the blurb it says that the hardware is very cheap to buy too. These are american based sites saying that all the hardware is easily available so why not give it a try though it could all be a con - $49 dollars might be worth a try
Q:how can i optimize power in a solar panel?
first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky. For overall maximum versus time, you need to be near the equator. Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load. .
Q:how do I become a solar panel contractor?
Contact some solar panel manufacturers or distributors. I recently started working for a solar panel dealer and they can't find enough qualified workers to install here in the US. Desperately seeking electricians but don't pay well.
Q:Solar Panel Batteries?
If interested in much more info about solar panels then I would suggest reading these articles renewableenergyarticles.blogspot....
Q:Do they make solar panels like this?
Homemade okorder.com
Q:Solar Panel questions...?
I have a system that was installed last year. I have 20 panels which provide me with about 75% of my electricity. I do use less electricity than the average home. I use an average of 45 kwh in the summer, my neighbor uses more than double that. I paid $26K for the system, but I got a $0K rebate from my utility and the US gives a fed. tax credit. I am saving about $2K per year, so it will take just over 6 years to break even. I also have what I think is called net metering, my utility allows my meter to run backwards when I generate more energy than I use, so pretty much the entire time the sun is out in the summer. Having energy efficient appliances, reducing standby energy and using conservative climate control really helps keep my usage down. Weather striping, insulation and clean well maintained systems all help as well.
Q:What kind of Solar Power panel setup do I need for this?
Unfortunately solar panels are low output,generally only 2 volt and very low amperage,so you would need to build a multi panel array with a DC-AC converter all together costing several hundred dollars which would only work during sunlight.Just roughly figuring,about $800. Plan2-Solar charger,battery bank,and DC-AC inverter so it would work 24hrs a day,also several hundred $$. Solar power does just not seem feasible(to me)in this application.By far the cheapest set up here would be an extension cord fromhouse to the bucket.260 watts per hr is a fairly lightweight draw,even not figuring the thermostat's cycling it on and off as needed.Electricity is sold in kilowatt hours(000W/hr).This bucket would use(not allowing for thermostats control lowering it)appx 6000watts or 6KW per day.Depending on your electrical cost per Kwh it would cost very little to run.(In my location appx 50cents a day) or appx the same amount as my computer(325watts total)) Note that that would be a maximum rate,and would actually be less due to thermostat cycling off and on as needed.
