solar power light
how can I build a small solar panel to power a light bulb?
as an experiment.
and as a secondary aspect, I would also like to be able to store the electricity to turn on the bulb at night.
can I conduct this experiment without spending a lot of money?
can I conduct this experiment without spending a lot of money?
I’m afraid that it will probably cost more if you try to build it yourself, rather than just buy an existing solution.
I have seen small 3-watt solar panels powering rechargeable LED lights – those go for $45 at flea markets in this area. They’re bright enough to read by in a tent if you’re camping, but you wouldn’t want to use it as normal lighting in a room. The next step cheaper is to buy a solar powered walkway (lawn) light – probably less than $10 each, but only good for marking a path, as there’s only one small LED inside.
If your hope is to power a room light, such as a 13-watt compact fluorescent, then the system is going to run a few hundred dollars, most of it for the solar panel.
