How Can You Get A Light Bulb To Power A Solar Panel

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, 1000W of light or more per square meter. A light-bulb is weaker, so less output. A 100W bulb may have only 5W of light, and it doesn't cover the panel, so you can expect something like 1% 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.

Using light bulbs to power solar panels?

For part of my science fair project I need to use light bulbs as my source of light for my project. I'm sort of new to photovoltaic cells...

Will a solar panel like this generate power off a light bulb? I'm thinking about using 50 watt halogen light bulbs.


How do hook up a solar panel to a light bulb?

Jeez dude, not well specified. Your panel probably supplies 24 volts open circuit, but what is its I-V curve? The best thing to do is to hook up a circuit that takes your panel output and regulates it to 18 volts, so if your panel has the current capacity to blow the bulb, it won't. But that's complicated; if your panel maxs out at 10 watts, and your bulb is 10 watts, just hook it up, there won't be a problem. If your panel is 5 watts, and the bulb is 10, it just won't light up all the way, etc. Where the heck did you get an 18 volt light bulb? Is it a little bitty pilot lamp bulb? Is is incandescent, or some LED assembly, blah blah blah

Can there be solar panel , but for light bulbs?

It is true that you can convert artificial light into electricity, via photocells. The actual percent of conversion is very low and most of the energy output of an electric lamp (or LED for that matter) is heat. A low percentage of energy from a lamp is visible light. All of the light output is absorbed by matter and converted to heat as well. So in essence, a lamps output becomes heat with 100% conversion.

Therefore, in terms of providing energy, a lamp has 100% energy conversion to heat, while providing a small percentage of light output in the process...without the huge cost of a solar panel.

Where can I buy a solar panel to light a light bulb?

Robin answer is the only one that is sensible. A image voltaic panel can not capability a mild bulb and not using a storage vessel. A panel can save the present to a battery or 2 till mandatory then the dc mild will save your cash rather of paying for for a converter. counting on your section a wind powered generator may well be greater effective. OH a internet internet site would properly be chanced on at mom Earth information. they have alot of websites for human beings wanting to bypass green even can help individual who're wanting to bypass off the grid.

Can u use regular light bulbs to power a solar panel?

Technically, yes. But you won't get much energy out of it.

A good example: regular solar powered calculators (which require very little energy to run).

For bigger devices you would need way too many light bulbs and larger solar panels.

If you have taken physics classes, remember that energy is conserved so whatever energy you put in your light bulb it will come out as visible light, UV rays and heat. Your solar panel will absorb only a part of as much light and UV hit its surface and that will become energy again (much less than the energy that you originally put on the light bulb).

Can a LED light be used to power a solar panel?

Probably, but you would be disappointed at the amount of energy you got from it. Some LEDs can be very bright - place a sheet of white paper in the sun, and shine the LED on it and it will be visible, so is brighter than the sun at that wavelength (colour). However the spot is only like 1cm diameter.

For a panel to work all the cells need to be illuminated. When the spot from an LED is spread across the whole panel in some way, it will be very dim, considering the area of the panel is maybe 1000 times greater than the area illuminated by an LED.

The result is that the output of the panel is very small, a few milliwatts, even allowing that the light was spread across the panel with no losses. Another way to look at it is the panel is only about 10% efficient at converting light to electrical power. The optical power from a very bright LED is of the order of a few hundred milliwatts.

If you are talking about a single solar cell of small area, say 1 or 2 cm^2, arranged so that all the energy from the LED falls on the cell, the output will be more useful as a sensor of LED brightness etc. It will work better because the areas match better. It will still only be milliwatts output. This would be more usually called a photo-diode.

Depends on the bulbs wattage and the hours they at turned on daily.I would suggest to use 12v compact fluorescent lights at 11w, will illuminate decently and not too expensive.In sunny days your 50W panel will charge the battery enough to turn on three lamps 4.5 hours each, or two lamps 7 hours each.If you manage to buy LED lamps at 12 volts, a 7 watt lamp will illuminate almost like the 11 W fluorescent and you can increase the abovementioned times by 50%.You will need a 12 volt battery at some 40–50 Ah, that will be enough to cover 3 cloudy days. Better buy a battery for deep discharge but a car battery will do the job, only they will last 2 years and that is if ensuring to charge them on a daily basis (except on the cloudy days).Hope this helps

Yes, it surely will work the Power will be generated.We in our college have conducted an experiment similar to this one.

How many 60 w light bulbs can be powered using a 1000 w solar panel?

In design one never go over 80% otherwise the working components are at risk. (Its like running an audio amplifier at full volume all the time - it will blow.)

Number of bulbs = 80% * 1000w/60w = 13.33 = 13 bulbs.

But you do not want to use the bulbs at 12 noon, do you? So you need a battery to charge with the solar panel as energy source.

The solar panel power rating is with the sun shining directly onto the panel. By sunset or sunrise the power will be much less.

You have to take the hours of sunshine, and of no sunshine into consideration.

You have to determine how long you want the bulbs to take current.

You need to charge a battery which will have to run a power converter to give the correct voltage for the bulbs. The power converter will loose some watts by heat and electronic control.

Its more than what meet the eye ... Stick to over-design.
