Q:Anybody install solar panels themselves?
i do no longer yet i comprehend lots on the venture. e mail for information. a great number of ppl set up them yet just to cover there electric powered warmth/air. It saves them money. i comprehend lots of people who've tiny ones exterior there window to means the lights fixtures in that one room. Its no longer an eye fixed sore the two. i stay in Canada.
Q:Why are solar panels made from silicon and not magnesium?
Silicon is a very good conducter. Probably the best for electricity.
Q:Joule Thief vs Solar Panel?
Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
Q:Can you make a solar panel shift sideways?
having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
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:How Can I Reduce A Solar Panels Output To 3volts From 9volts?
Solar panels generate DC power. Changing DC voltage is hard, which is why the power grid is AC voltage. AC voltage can easily be changed with a transformer. To keep the DC power (watts) the same at a lower voltage you need a DC to DC converter. That basically changes the power to AC with an inverter, changes the AC voltage to the new value, then rectifies it back to DC. It is probably hard to find a commercial unit that handles those voltages and then it will be expensive. But I have a simple solution in the special case of a solar panel. Solar panels are made up of smaller solar cells. The basic solar cell has a very low voltage, like half a volt. The panel has many of them connected in series to make a higher voltage. Just cover (shade) some of them and the voltage generated by the panel will be less. Of course that reduces the power. And you may need to experiment with shading different parts of the panel and measuring the result with volt meter.
Q:solar panel in a grid tied system?
That would depend on the panels themselves. There are many different specifications when it comes to panels, but if you wanted to be technical, just about any would give some impact - even if it were only a few cents.

Q:What do I need to install a 40 watt solar panel?
Whats the size of battery ? The time needed for your 40Watts panel to fully charge a battery depends on the size of battery. Usually battery size is mentioned in Amp-Hours (AH).
Q:how many solar panels will i need?
you silly ! with Solar there is always room for error . you have to build it in to your numbers . solar is full of errors . So you should plan on producing at 3 times what you expect you will need . then you have enough .
