How much electricity can a solar panel produce can it power a light bulb and also have electricity spare?
Question:
Answer:
Photovoltaic panels and modules
For Mono and Polycrystalline cells the power output of a single cell is quite small (typically about 1.5 watts), so in order to obtain usable amounts of electricity, many cells are interconnected in series and in parallel.
They are built into a module, or panel, with an aluminium frame and covered in glass for protection.
Modules usually occupy about half a square metre and are virtually maintenance free. Sizes vary, but a typical panel might produce between 40-60W in peak sunlight and comprise of 30 to 40 cells.
These panels produce a 'nominal' voltage* of 12, 24 or 48 volts d.c depending on the way the cells are configured within the module.
Modules can then be connected together, in an array, to give higher current or voltage outputs. * actual voltage is higher to provide the necessary charge for a battery.

Lots of FAQs on 2nd link...
how big is the solar panel and how long has it been exposed to sunlight(this makes a difference), When done correctly you can power a whole house from solar panels, they are used in Europe a lot.
Solar is a very weak source of power that costs too much for most people to implement. At night you will have no lights unless you use electricity.
The costs at this point outweigh the benefits at this point.
there are many different types of solar panels, also the area and time in sunlight is a factor. But probably about 20-50 square inches could power a lightbulb if it were in bright sunlight continually
the power produced by solar panel debends on two things
the sun light ( its different if you but it in Egypt for example from but it into Denamark)
the area of the solar panel
but an approximation is made in strong sun light ( in tropical countries) the power produced can reach a 1000W per square meter
andn you must know something sometimes solar power is not a main source some times it is used to reduce power consumption during the day and in the night they just switch over to normal electricty
Yes. This depends and the size and efficiency of the solar panel and the power consumption of the light bulb. If you want constant power when the sun isn't available, the panel should also be powering a bank of batteries and power drawn from them.
My closest exposure to solar panels was a neighbor who took a single one with him camping to power a single fan. It did a fine job of airing his tent during the day so it didn't heat like an oven. This was an application where the power was only needed while the sun was shining.
Compare to windmills originally installed to pump water for livestock and retrofitted with electricity generators *and* a storage battery. The primary use for the electricity was for listening to radio in the evening, when the reception was better. The use with a battery rather than purely for immediate power is demonstrated as being the norm rather than the exception in home applications.
A 5 ft by 2 ft solar panel in the desert near the equator will light a 100 watt light bulb and cost you $600 dollars. Unfortunately, you'll need a $2500 inverter to change it from 24 volts DC to 120 volts AC
Depends on the size of the solar panel and its design. There are various types, some are better than others.

A more efficient user of sunlight is the solar furnace.

Well... yeah. but how useful is a solar powered light bulb? now if you could store the energy, that would be something else :)
Nowadays with he progress of solar energy, powering a house is feasible.
Solar panel sizes, batteries and DC to AC converter will have to be calculated according to the electricity consumption you are expecting to use.
You can also have excess energy.
If your solar system is connected to the grid, this excess energy will generate additional savings to you.
