Q:How do solar panels work?
A solar panel is a collection of solar cells (photovoltaic cells) connected together and put in an enclosure. The solar cells work by taking advantage of the photovoltaic effect. The effect is that in a semiconductor P-N junction, when photons of suitable energy strike the junction, an electron and electron-hole pair are generated. This creates a voltage difference between the two sides. When this voltage is applied to a circuit, the electrons are able to flow through, creating usable energy.
Q:help setting up a solar panel system?
If okorder.com/ If the minifridge is one that plugs into 2 volts, that should be okay. Anywhere you can eliminate the inverter will help. Such as converting the stereo over to 2 volts. The nominally rated panels should be mounted at an angle to maximize the solar aspect/exposure. Essentially your lattitude plus 2 degrees for simplicity. If you add 60 Watts in panels you will do much better. Your 3 panels when installed correctly will actually yield over 5 Watts each panel at midday. If you do not achieve that, something is wrong in either the wiring, or a panel. It translates to about point2 Amperes to point5 Amperes at midday. If wired in series for 36 volts, the total current output will be same as a single panel (nominal 5 Watt), but at a higher voltage. If wired in parallel, you achieve the 45 Watts at nominal 2 volts. Watts is voltts times Amps. Also converting your tools over to run off the 2 volts will help, Or charging your tool batteries off the 2 volt buss. There are buck/boost circuits that would be capable of charging the common 4.4 and 8. volt tools out there.

Q:lighting my pond with solar panels?
select 2V, and it will tell you how big of a battery bank and how big of a solar panel you need. For my example, I need a 7ah 2V battery and a 20watt panel.
Q:With everyone thinking green...how green are solar panels?
No matter how electricity is generated you must use materials to build the plant. I don't know what my panels are made out of, and I don't know if they can be recycled. I also don't know what my other electric plant was made of or if it can be recycled. I do know now that it has been made and installed I'm not using coal or oil to make electricity, I'm not creating any emissions, and I won't have to worry about how high the cost of electricity goes.
Q:Polycrystalline solar panels are good or single crystal solar energy is good
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (
Q:How do you connect solar panel?
If that 55-watt panel has an open circuit voltage of 7-8 volts, you may get more efficiency by omitting the charge controller completely, and connecting the panel straight to the battery. 55 watts is marginally too small for a 200 AH battery at 2 volts, by the way.
Q:Reflectors or mirrors around the solar panels.......?
You could (an example of concentrating sunlight is called cloud gain, where the edge of a cloud will intensify sunlight as it passes between the sun and your panels), but that will make your panels run hotter and will probably reduce their life. It's better from a system design standpoint to simply get another panel or two. DK
Q:im trying to power up a cell phone and laptop with a solar panel.?
They are powered from internal batteries, so what you really want to do is to charge the batteries. Take them one at a time, as they have different power and voltage requirements. Don't try to do them both together, unless you use an inverter. To directly charge a battery from a solar panel, you need to find out the voltage and current requirements for the charge operation. Then find a solar panel with a voltage somewhat higher. the current can be lower, it will just take longer for the charge. You will have to monitor manually the state of charge of the battery(s) to avoid overcharging and damage. Another alternative is to get a solar panel that will supply 2 volts and use that to operate an inverter that will output 20 VAC with AC sockets on it. then you can plug in the battery chargers that you have, and they will handle the batteries correctly. Or you can buy solar panels with built in circuitry to handle the charge control. .
Q:Can I power up 2Watt bulb using 2Watt solar panel power?
. Practically no. You have to account for startup current, and losses in the system. Ideally you would size your solar planel to provide the power you need to charge batteries in the day, for your needs at night. 2. Watts=Volts times Amps Really you just need to match the load and supply for volts, and make sure the supply has enough capacity to run your load. Current will take care of itself., in that the load will take what it needs to do its work. 3. It will bring the voltage down, causing the light to be dimmer.
