How do i cost-effectively provide basic light with solar power?
Question:
Answer:
The sun emits energy to earth in the amount of 1000 watts per square meter. If you use a solar cell panel you convert about 15% of the solar energy per square meter by a solar panel. This energy is produced in electricity amps and voltage only when the sun is shining. If you want a continuous use of power, then you should store the energy during sun light in deep cell storage batteries like those you have in your car, lead acid, or cadmium batteries. In this case you also need a charge controller, so that you do not over charge your batteries and if you need AC voltage then you need a converter. For lighting only you probably need a panel which produces 100 Watt maximum.
The most cost effective way to provide light with solar power is to install a sky-light and open the curtains.
If you want to continue to provide light at night, you would need a solar cell with a "deep-cycle" battery and low voltage lights. LED type lights will draw less power than standard incondesents. This may be the route to take.
You are asking the wrong question you should be asking yourself why you would want to go to a fourth world sheet hole sewer country like sierra leone. Stay away and let them kill each other without you getting in the way.
