Q:Anyone know if there is a solar panel that you can travel with that is not USB plug in ?
Solar panels require a charge converter before it can be used by an AC source. There is no direct solar panel with built in charge converters that I know of because, when purchasing panels, you must purchase the wattage requirements of the job (this can be several panels linked), and a charge converter that will handle the <? panels required. A chain of stores up here in Canada have a portable battery pack that has a solar panel to increase its charge capacity or duration, but its not something you would want to lug around for long periods of time, because is weights in about 3 lbs.
Q:Solar panel angle question..?
You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav
Q:How do you set up 30w solar panel?
With a 30 watt panel, producing about 2 amps, your not going to have much power from that. A 22 AH battery will give you 2 AH of usage. A battery should never be drained below 50%. What this works out to be is simply Amp draw for 2 hours. Which equals to 2V light bulb that draws amp for 2 hours. Not much. Now to replace that usage with your 30 watt panel, provided the panel is clean and in max sunlight, it will take 6 hours. If you attach an inverter to your system for 5 Volt Usage then the DC voltage drawn from the battery is very high. Example: Say you use a 5 Volt component that requires 50 Watts per hour to operate. The inverter will draw 5 Amps out of the Battery every hour to operate that component. That gives you and /2 of use before the battery is down to 50%.. Maybe that will be enough to charge up a standard Laptop battery. I have 2 30 Watt panels that produce 5 Amps, 4 6V batteries that have 480 AH and a 25 Amp Controller with a booster that increase the amp output to 20 Amps per hour. I live full time in an RV and raise the panels to get max output when I am parked. This system provides me with all the 5V throught the 500 Watt inverter that I need. Good luck on you system.
Q:Finding the output of a solar panel?
You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.

Q:Why only Photo-Voltaic solar panels?
That sounds good to me. I'm all for any kind of new energy as long as it's renewable and doesn't pollute the environment. I'm even a fan of solar water heating.
Q:With everyone thinking green...how green are solar panels?
All kidding aside, you will possibly desire to do not forget that the White abode is the suited representation of the u . s . to the worldwide. because of fact of this that's equipped so vast and ambitious, and ambitious. image voltaic panels and wind generators will tutor a destructive connotation, form of like antennas on a boarding abode with wires putting down ought to characterize a ghetto to the castles and empires of the worldwide. there is likewise the reason for uninterrupted electricity throughout the time of an attack on the capital, it continues to be a area of the regulations of conflict you recognize. including option potential sources might supply a splash as to how the device works, or no remember if it somewhat is not that way, might come throughout the time of as being hypocritical, or purely for tutor (Like that's not being achieved now...)
Q:Question about solar panels?
One key piece of information missing is the average number of peak sun hours per day. This will vary by location. It is latitude, regional weather, and site shading must be considered. Another consideration is the loses. The 60 watt solar panel is a DC voltage. The 2300 kWh is for the AC power consumed. There are loses in the inverter to change the electricity from DC to AC. There are also loses for wire resistance, soiling of the panels, wire resistance, etc. To work out an example of the math, I'll use 5 peak sun hours and a total efficiency of 80%. The math can be worked out as a single formula but I'll break it into steps for you. (2300 kwh/month)(month/30.4 days) = 75.65 kWh/day (60 W)(5 psh)(80%) = 240 Wh/day = 0.24 kWh/day/panel # of panels needed = Energy use / Energy generated (75.65 kWh/day) / (0.24 kWh/day/panel) = 36 panels.
Q:What to do with a solar panel?
Solar cells convert the energy of the sun into electricity. By using items commonly found in the home or your local hardware store, you can make a solar panel to demonstrate this photoelectric effect. You can also save energy by converting some of your traditional electrical supply over to solar power. Use sheet metal shears to cut the copper flashing in a square or rectangle to fit the size of the electric burner. Be sure to use a piece of copper flashing that is thoroughly cleaned. You may use sandpaper to thoroughly remove any sign of corrosion before proceeding. Place the copper flashing on the electric burner and turn the burner on. You will need to cook the flashing for as long as 30 minutes or more to develop a thick layer of black cupric oxide.
Q:What are the main components of a solar panel?
For vacuum tubes solar heaters the main component include: solar tank, vacuum tubes, solar frames, and the pipelines and fittings of whole system
