Solar charger can work without sunshine?
-*Solar charger*- is convenient for people who usually travel out. But sometimes I want to ask such question “solar charger can work without sunshine?” Perhaps it is a stupid question. But I still want to know the answer. And if they can not work, is it still convenient. You can not use inside and you can not use in winter. Only without sunshine, it becomes rubbish. So is it worth for us to use? -- woterm ------------------------------------------------------------------------ woterm's Profile: http://forums.yourdomain.com.au/member.php?userid=109 View this thread: http://forums.yourdomain.com.au/showthread.php?t=76733 |

Only without sunshine, it becomes rubbish. So is it worth for us to use? Well, technically, if it works without sunshine, we would have to call it something other than a "solar" charger. Generally, photovoltaic (solar) cells output a current in relation to the amount of light that strikes them. The more light, the more power they put out. So you could use a solar charger by the light of a campfire for example, but it probably would not charge as rapidly as in bright sunshine. So the question is does the charger you have in mind work well even under subdued light for it to be valuable? |

But I still want to know the It depends on your definition of "sunshine". A solar panel will give power on a cloudy day. Some would not consider that to be "sunshine", but certainly the light is from the sun. -- -- r.p.e.35mm user resource: http://www.aliasimages.com/rpe35mmur.htm -- r.p.d.slr-systems: http://www.aliasimages.com/rpdslrsysur.htm -- [SI] gallery & rulz: http://www.pbase.com/shootin -- e-meil: Remove FreeLunch. -- usenet posts from gmail.com and googlemail.com are filtered out. |

So is it worth for us to use? Like they said, yes, it will work.. but it may not produce enough power to be useful. Most devices that you are likely to attach will have a thereshold voltage/amperage/wattage, and unless the power source delivers that, they will not operate at all. You need to do some homework, or explain what you will be doing with it and verify that it will be sufficient before purchase. |

Solar charger is a misnomer.....They are light chargers.....They turn photons into electrons. The brighter the light (photons per square surface area per second) the more electrons per second will be the output.....A cloudy day will still provide some light, but not as much as direct, unobstructed sunlight. but even a dim electric bulb will induce some electrons to flow...... |
