A very practical usage of solar battery power is to disinfect water
supplies so that they become drinkable. Water can be disinfected either through
solar water pasteurization or through solar water disinfection. Solar water
pasteurization relies on solar power to make the pasteurization process work,
involving sustaining application of heat to water for a certain period of time
so that water temperatures stay within the 60 degrees to 70 degrees Celsius
range. Solar water disinfection is a less intense use of solar power because
the water is aerated first by vigorous shaking in a container which is then
left to be exposed to direct sunlight.
All these uses of solar power indicate that eventually solar system power may become a
widespread source of power not just for large enterprises but also for the
average human household. All that is required is for people to be able to
afford the technology and its upkeep for solar power to become a practical and
dependable source of power on a daily basis.
