Q:How long does it take to charge a 2v deep cycle battery with a 0 watt solar panel?
What is the open circuit voltage and voltage under load with the panel in full sun? Assuming it is typical of many 0W panels, the open circuit voltage is 2V and the voltage under load is about 7V. 0W/7V is 588mA. A typical car battery is 40 Amp Hours. Amp Hours, or Ah, is the capacity of the battery. How much current a battery can delivery starting a car is called cold cranking amps. A deep cycle marine battery will typically be more than 40Ah. A 40Ah car battery at 50% charge will more than likely start your car in fair weather. Cold weather is another story. So, to get a completely dead car battery to 50% - 20Ah - would be maybe two days of full sunlight - with only a 50% charge, or about 2.2 Volts. Not a great battery charger - however - It makes a great supplement, and can offset the use of DC powered equipment in the vehicle while the engine is off. Things like low-wattage lights, cell phone chargers, tablets, and the like will drain the battery down that much slower. I have a number of powered but low current items on in my truck all the time. A panel helps offset some of that drain if I don't drive for a few days.
Q:Solar Energy - What would these solar panels power?
A solar panel that is rated at 60 watts would produce that amount under the most favorable conditions of direct sunlight at noon in a good location. This would taper off to nothing at the beginning and ends of the daylight. A 60 watt Panel operating at full output for hour would produce 60 watt hours. If we assumed a straight line of output from zero to 60 watts and back to 0 again over 6 hours the average output would be 30 watts x 6 hours = 80 watt hours / day x 365 days = 65700 watt hours in a year / 2 = 5475 watt hours in a month. You lose about 0% converting from DC to AC. This reduces this to about 4927.5 watt hours. Your bill is measured in KW hr which are 000 times bigger. This is 4.9275 KW hr or .24% of your last month's bill. At a national average of about $.2 per KW hr the energy out put for one month would be equal to about 60 cents.
Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?
In the practical sense, the differences are trivial. I'd buy on price per watt, unless space is at a premium (it isn't for most installations).
Q:Build your own solar panel, scam or truth?
Electric panels are not feasible for most people. They are two super thin layers of polarized material. When the sun hits them electrons move from the first to the second layer with an amount of force. You can't duplicate that at home. What you could do is setup solar heating panels and run them against a Stirling engine. This technique is typically more efficient than normal electric panels anyway in industry. They have heat on one side and cold on the other to generate force. Hook that to any generator to produce electricity. If you are successful building a home system, blog about it, others will want to know precisely how you did it.
Q:Recycling Solar Panels?
yes they are very recyclable, and you would actually be suprised at how much you get back from them just as materials, as there are still very valuable materials in them.... Often solar shops will accept them back for at a fraction of what you paid, as they can send them back to the manufacturer who then do all the material stripping in them and recycle all the materials there. Mainly depends what type of solar panels you have.... Most probably poly-chystalline or mono-chystalline. If they are that cool blue or black psychadelic looking panel also the manufacturing make that effect is also costly so they would probably look to buying that as well.. I would ask a solar shop where it can be done as the silicon in them are still a very prescious substance..... I would definatly not throw them out or pull them apart just yet
Q:Why dont we have a gigantic solar panel system in the warm states,stretching miles across to supply the usa?
To add to what others have said, more importantly, what will you do at night !! Electricity is VERY hard to store, so it has to be produced all the time. Even cloudy days cause problems. Lack of raw materials, costs compared to other forms, and the fact that miles across will not even be close. Think more like a state across to supply the US. Think avout this yourself or ask your parents if you are younger. To go solar are you willing to have your power bill be 0-20 times the current level for the next 30-50 years? You will find the answer in NO. I think those numbers will even be conservative. On your depression argument. Remember that the unemployment rate was 7% where it is 5% now. Also, the real end of the depression was WWII. I hope we don't do that again. Can you imagine trying to double federal spending? I don't think taxpayers would go for that. Start in your own back yard. Become energy efficient yourself. Install solar, use an electric car, and do everything you can before you spend other peoples money.
Q:How do you install solar panels?
This is still not a trivial project, although it is getting easier. The usual way to do this is to contact professional installers for free quotes. In the process of getting the quote, you'll learn what considerations go into sizing a solar system. They'll look at your energy usage, and also whether your house has a good, clear, south-facing roof that doesn't get shaded during the day. They'll also look at your electrical panel to see whether they can hook right up, or additional work is needed. There are rumors of companies like Akeena planning to sell panel kits in Home Depot (in areas that Akeena does not directly serve). The idea would be that a pro installer would pick up the kit there, but a highly skilled homeowner might be able to make it work. A permit will probably be required by your jurisdiction, but that's no different than applying for any other construction. And you'll have to inform your power utility in advance, which may or may not be routine, depending on how often people connect solar in your area. If you want to see how we connected our system, a link is below. I did not really save money by doing it myself. That's because pro's can get better prices on the panels, which makes up for the labor cost.
Q:What do I need to install a 40 watt solar panel?
Your demand is high. You require at least 5KVA (5000watts) out put with an appropriate battery storage and inverter..
Q:what can i do with a calculator solar panel?
It wouldnt be worth your time really to try and hook it to a psp. You would have to build a circuit to match the voltage of the solar panel with the voltage of the psp. one of the few things i can think of would be a model windmill that used a very small solar panel to turn a very small motor attached to the rotor on the windmill. If you want a solar panel to charge your psp, look on OKorder, theres plenty of cheap low wattage solar panels that with a small solar panel regulator can put out enough 2v dc energy to possibly charge your psp
Q:Question about commercial solar panels?
they are in a position to be in case you're properly knowledgeable and experienced of their assembly and working function, offered you acquire the comparable severe high quality grade cells and do perfect assembly. probability is robust although that your first a number of could be in hassle-free terms somewhat below par till you rather get the carry of it and strengthen into properly practiced purely because of the fact the pros are. Does take a important volume of grunt paintings although so determine if it rather is great use of a while or in case you will do greater beneficial to earn at your prevalent paintings and pay a professional to do this which they do superb.
