This report presents the results of an-in depth survey of solar power as used for water pumps, solar cookers and wood burning stoves.
The purpose of this survey was to collect, organize, and disseminate pertinent information on available solar power technology that will benefit the people of less developed countries of the world.
I am a proponent of solar power, but like Steven Harris I don’t necessarily think using solar for electrical generation is the most efficient use of the sun.
It is inefficient to covert energy more than necessary
As each conversion causes loss. Solar power in a house typically has 5 such conversions:
- Solar Power to DC electricity
- DC to Chemical Battery
- Chemical Battery to DC
- DC to AC
- AC to heat in a stove, fridge, washer or whatever.
Every time you convert energy from one form to another you get loss.
It is much simpler to take the heat of the sun and use it directly. Solar works best for things like cooking and heating water. However, solar electric power is reliable and the amount available over the year is easily planned for.
I like solar and have several panels of my own, and I continually use documents like this PDF to ensure I am using solar in the more efficient way possible.
