does the solar panels on calculators really need light from the sun to work?
or does any normal lights in rooms ( fluorecent, incandecent, etc) also power the calculator?

I mean when light hits the solar panel where does the energy go and what does it become? Be specific.
I pass about 3 township every day for my commute. I have seen Solar panels are been installed on the street light poles in every town that I pass.
Some of the poles do not have any Light Bulbs on the top – but still the panels are installed.
I wonder why the panels are for – Of course the obvious reason to send the light energy from the sun to the grid.
Is That it.
I`m working on a solar project, need to know how many cells would it take to light a 4 watt bulb? I put some cells in series to get my 13-15 volts, only problem is when I put them in parallel I can`t get the needed volts or current needed to light the bulb, anyone have any idea`s?
Are some solar lights better than others, if so how can you tell before buying them?
I am looking for outside lights that are solar and would generate lots of light. Is it possible to fine?
I would like lights for the front door and back door and one light that can be the sensor for the driveway.
