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 Panels!!???!!!?
Solar Panels are collections of solar cells. These panels basically collect the incoming sun's electromagnetic radiation and convert it into electrical energy. A solar cell is any device that directly converts the energy in light into electrical energy through the process of photovoltaics. The development of solar cell technology begins with the 839 research of French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develop when light fell upon the electrode.
Q:solar panels, wattage?
The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
Q:How efficient are solar panels?
Solar panels are 5-30% efficient in turning light into energy. I'm not sure why it isn't 00%, but methods are constantly improving, and the panels are getting more efficient with time and research. Solar panels work with photovoltaic (PV) cells, which are made up of two very thin layers of semiconductor with a middle junction layer. The kinetic energy in light photons create a current that flows into whatever electrical cord it is attached to.
Q:What ever happened to solar powered panels?
I saw a commercial the other night for a fan you hook onto the top of your car window, and it's solar-powered. (supposedly cools off your car while gone...as opposed to just cracking the windows some). Also, I've seen traffic lights and emergency beacons on the highway powered by solar panels.
Q:How to build a small SOLAR PANEL that will light a 60 watt light bulb?
Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.
Q:How about solar panels?
I have a better idea . Why don't we pull our troops out of there and take the money that we spend to kill people and build a mass amount of solar cells and hand them out to our own people maybe give one of our hungry people a little food to go with it . You could even take a little of that money and put some kids through college . I can think of thousands of things to do with that cash . Why don't we ever take care of our own people first ?
Q:Question about home solar panel systems?
As Ed said, that .2 kW is an instantaneous rating in bright sun. The way to do this right is to consult the maps here rredc.nrel.gov/solar/old_data/nsr... to find the number of equivalent sun-hours your location gets per day. Select, Average, Annual, Flat plate tilted south at latitude. A map will come up. For northern California, it shows 5 equivalent sun hours per day, for example. If the system is .2 kW, then .2 x 5 = 6.0 kWh of energy the system will generate per day, on average. That takes into account cloudy days, short winter days, long summer days, everything. The 2.4 kW system would give double that, obviously. But that's an example, based on a specific location. Phoenix would do better, Seattle would do worse.
