How can I cost-effectively provide basic light with solar energy?
I'm moving to Sierra Leone, the poorest country in the world. will not electricity, which will be. If I buy a solar charger 12v and 12v (say fluorescent) light can create as many lumens as a 60W light bulb, How many daylight hours can be offered each night (assuming 14 hours of sunlight)? Additional suggestions for off-grid are welcome.
The Sun emits energy in the earth to 1000 watts per square meter. Using a panel of solar cells convert 15% of solar energy per square meter per a solar panel. This energy is produced in amperes and the voltage of electricity only when the sun is shining. If you want a continuous use of power, then you must store energy during sunlight in deep storage battery cell as you have in your car, lead or cadmium. In this case, also need a charge controller, so no over charge the batteries and if you need the AC voltage, then you need a converter. For lighting only likely to have a group that produces 100 watts maximum.
