Q:question about solar panels....?
They create electricity from light energy provided by the sun....
Q:how are solar panels practical?
Solar Panels are practical because they provide electricity to your home directly avoiding the rates paid to the utility. They are pay themselves off in 5 years or less and supply an income stream in NJ for 5 years!
Q:Solar panel wiring trouble.?
You are probably wiring them incorrectly: with the positive on panel A connected to negative on panel B; and the negative on panel A connected to the positive on panel B. If you want then connected in parallel, connect the positive on panel A to the positive on panel B and the negative on panel A connected to the negative on panel B. But you will only get vdc. You can't get .5 volts from two volt sources. You can get 2 volts by connecting the panels in series.
Q:Best orientation for my solar panel?
Typically, solar panels are installed facing the same as your latitude = 2 degrees to the North measured from horizontal. 60 degrees from vertical = 30 degrees from horzontal will give almost as much power in June as in December = beginning of Summer. You can face your panels straight up = zero tilt from vertical = better for December/ not so good in June. Usually, the same tilt as your North facing roof is best as it simplifies installation and reduces wind loading. Shade from trees etc will much reduce the power you get. Neil
Q:Why are solar panels only 0% efficient?
Mainly due to reflection (micro-structuring of the surface helps here), incorrect wavelength of the light (the panel is only sensitive to a certain wavelength range) and heating of the panel (due to the incident light/thermal radiation). The remainder is either reflected or absorbed by the cell and re-emitted as heat. Absorption by e.g. the glass panel is slight (a few %), as is absorption/reflection by the necessary surface contacts (again, a few %). Higher efficiency is possible, but brings its own drawbacks (like higher cost). You could now go into two directions: - high efficiency cells/panels with (likely) higher cost and complexity for mounting (like lens or mirror based systems, aka concentrator systems, that increase the light level on the cells in order to increase efficiency) - low cost systems (cheap as dirt) that will allow you to cover every surface of a building, efficiency is less important if you can compensate by a much larger covered area As to the efficiency limit: there is a theoretical limit (from thermodynamics - don't ask me how or why) in the range of 30...40%, depending on which publication you want to believe in.
Q:How do you connect a solar panel to a motor from an RC car?
can increase your voltage from a single solar panel. In combination with a large capacitor, you could deliver short bursts of power to the motor which would allow intermittent operation.
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:Is it worth installing solar panels on a house that has no South-facing roof?
Depends how much sun you get. Even if you don't face south, you could still be able to harvest a lot of energy from the sun. You could install panels transversely so they face south to increase sun exposure, but this might not look so nice. Or you could move your house to the Southern hemisphere, when your solar panels should face north. Or install miniature windmills on your roof instead.
Q:Who made solar panels?
Many people think that solar power is a new concept. That couldn’t be farther from the truth. Harnessing power from the sun has been dated back to ancient civilizations. The below link is a timeline researched by the Department of Energy that outlines the major historical milestones of solar power.
Q:solar panel help needed ?
You need to know how many solar cells are in the panel and what is the rated current each cell will produce. This information should be listed on the panel. Each cell will produce from 0.5 to 0.55 volts DC per cell and each cell will produce a current that is dependent on the size of the cell and the type of material the cell is made from. If the cells are connected in series then the voltage of each cell will add together, that is if you have 30 cells connected in series they should generate about 5 to 6.5 volts DC. If each cell generates .2 amps, then you multiply the voltage of 5 volts DC times .2 amps DC equals 8 watts of power. The current of each cell does not add together when you connect the cells in series only the voltage of each cell. If you connect the 30 cells in parallel then the current of each cell adds together but the voltage of each cell does not. That is 0.5 Volts DC times 36 amps equals 8 watts. The power (watts) produced will be the same. See our blog on the products page to see how to connect solar cells in series and in parallel. We also have a PDF file of solar cells and their rated output current sorted by watts per area and their manufacturer.
