In this cycle, one can see the following steps:
• The sun provides the light
• The solar module generates electricity ( energy) from the light
• The solar battery stores the electricity
• Solar energy is used for various purposes, including providing light at night or
powering radios and televisions.
Benefits and Disadvantages of Solar Energy
Benefits
Solar electrical power has the following advantages:
1. It is convenient to use.
2. It is environmentally friendly-it does not emit
fumes, smoke or soot, nor smell like kerosene or
firewood. Therefore it does not pose a health hazard
nor cause danger of fire.
3. Lighting at minimal cost: solar electric systems
provide the most cost effective way of receiving high
quality home lighting since no monthly costs are
incurred.
4. Businesses selling solar energy components and technicians servicing solar
systems are gainfully employed while families can work longer hours.
5. The PV systems, which convert sunlight into electricity without emitting toxic
gases, can be used anywhere however isolated or remote. Therefore, poor
households have the capacity to generate clean electric power by installing
solar panels on their own rooftops.
6. Solar generated electric light helps to increase
literacy especially since people can read after
dark more easily than they can using kerosene
lamps or candles. Children find it easier to do
their homework and their eyesight, which could
have been harmed by poor lighting is
safeguarded.
7. Solar electricity is the most sustainable means
of meeting the electric power needs of poor communities.
8. Greater access to radio and television, hence more information available to
listeners and viewers leading to increased knowledge.
Disadvantages
1. Its operation and use is limited during cloudy
days.
2. If poorly maintained or installed, it can
become a great liability to the owner.
3. Initial capital can be costly.
