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:What specification of solar panel do I need?
I says they have DC to DC solutions from 2 V for most laptops.
Q:can a light bulb power a solar panel?
Yes light-bulbs work, sort of, but you have to illuminate every cell. The output is regulated by the cell with the weakest illumination. Additionally the sun is very strong, 000W of light or more per square meter. A light-bulb is weaker, so less output. A 00W bulb may have only 5W of light, and it doesn't cover the panel, so you can expect something like % of the sun's output. The spectrum of a light-bulb is actually more appropriate for a silicon solar panel, as the silicon panel responds best to red colours.
Q:How can I adapt an automotive reglator to a solar panel?
solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
Q:What if anything has been done to channel light power other than solar panels?
Have you seen the industrial solar power tower they built in Spain? It has a very large collection of mirrors which direct sunlight toward a single point at the top of a large tower. There a boiler turbine generates a lot of electricity! It is a genius concept that could easily be installed in North American deserts.
Q:im trying to power up a cell phone and laptop with a solar panel.?
Q:solar panels, help?
This is pretty much an exercise in knowing units and dimensional analysis. Watts are in Joules/second. So every second a square with the area(meters^2) of meter^2 receives 380 joules from the sun. In your case the square is the solar panel. So find the area of the solar panel in m^2. If you multiply area times intensity you can see that the meters cancel out and you are left with Watts(J/s). Since you want the Joules received in an hour you again multiply by how many seconds are in an hour. Leaving you with joules. What you have now is the total energy, but your solar panel is only 26% efficient, so just multiply by .26 and you will have your energy.
Q:What does it mean when a solar panel is 00w?
The 00w panel puts out 00w at peak power -- full sun. You will lose some power as heat through wires and other equipment and also some will be lost when it's converted to AC, unless you will be using all DC appliances and lights, etc. I think a good estimate would be about 0 - 5% loss. You will also need to know your average solar insolation, average amount of full sun you receive at your site. This will tell you how many panels of 00w it will take to get you 5kwh/day. Don't forget your losses as per above and add a little extra for peak usage that is needed when two or more major appliances and power uses start at the same time. Hope this helps. I'm glad you're checking into solar and good luck.
Q:2 Questions on Solar Panels?
Solar panels come in many kinds, using a variety of technologies and sizes, but the most common is still the crystalline silicon type. The power produced is variable, but the better ones you can buy approach 20% efficiency, and the peak energy from the sun is 200W/m^2 (Watts per square meter). This only occurs when the panel is lined up with the sun on a clear day with the sun high in the sky. The efficiency is also affected by how the electrical energy is taken from the panel, and the temperature of the panel. In the full sun the temperature approaches 60C, so the voltage drops. The links below provide a lot of information about such matters. A BP panel 50mm x 674mm gives a peak power of 20W. This is .07 square meters. As you can see this is very close to 20%. (The third link). However this is less in practice because the sun may not be full sun and may not be perpendicular to the panel. The output drops as the cosine of the angle to the sun, more or less. Even with peak sun this would produce only about 00W charging a 2V battery directly, unless an electronic Maximum Power Point Tracking (MPPT) charge control is used.
Q:Cars with Solar Panels?
Sailboats typically run on wind; hence, Sailboat. I haven't read your article on it though; but, I would think that the solar power would be for the battery powered stuff and possibly a little motor for it. For a car... There are competitions, right now for solar cars. Only they are very light and don't really go that fast. The panels tend to be large and weight a bit more than one would think. I don't understand why they can't simply make a car generate power simply by the rotation of the wheels itself. They could take a hybrid, take out the gasoline portion and it would simply recharge the batteries by the friction of the turning wheels.
