Solar energy advantages & disadvantages

Energy Smart PTY Ltd is a natural, permanent, continuous, renewable source of energy. Being the inexpensive, easily available source, it has tremendous potential that can be used for the welfare of mankind. But in everything it is very important that we look at both sides;

Disadvantages

The main disadvantage is the initial cost; the equipments used to produce solar energy are still expensive. Solar cells cost a great deal compared to the amount of electricity they’ll produce in their lifetime
The efficiency of the system also relies on the location of the sun.
The system is also limited to areas with sufficient sunlight.
Potentially large areas of land are required for large-scale solar energy projects
The main disadvantage of solar energy is that it’s dilute. This means you have to have a lot of solar collectors installed around your house.
Considerable amount of energy is lost when DC (direct current) from the solar cells has to be converted to AC (alternating current).
Solar energy cannot be used in industries; this is mainly so because factories require a lot of power to run their machineries.
The batteries used to store the energy such as lead acid batteries pollute the environment.
Solar powered cars have a fairly slow speed as compared to other general vehicles
The production of solar energy is influenced by the presence of clouds or pollution in the air.
Charging of electric cars (such as the Tesla Roadster) will take 53 hours using a 1KW system. Assuming you only get 8 hours of full sunlight, thats almost a week!

Advantages

Though expensive to install initially, there is saving in the long run as you save on your monthly bills
Solar energy is a renewable resource in areas where there is sufficient amount of sunshine
You can start with small amount and then expand as your need expands
There is very little maintenance required: when the solar panel have been put in place no fuel or lubricants need to be supplied.
Low running costs: as the prices of fuel continue to soar, solar energy remains free after the initial installation costs.
It will save you money on the electricity bill if you have one; the savings is immediate and for many years to come.
In some countries government gives incentives or tax rebates to those who are using solar energy
It is easy to install
Healthy and safety benefits; in some poor countries people use kerosene for lighting and cooking which has resulted to accidents of burning of houses and property. Solar energy is safe to use.
Reliability: solar energy is a reliable source especially in those countries with sufficient sun light.
Though expensive to install initially, there is saving in the long run
Solar energy works entirely independently, it does not require any connections or anything, so it can be used effectively and easily anywhere. Systems can be set up anywhere, in remote locations as well.
Unlike traditional generators, they can be unobtrusively installed internally, require no fuel.
Solar does not require manual start/stop intervention.
Solar systems are the quiet, fuss-free and reliable answer for every situation that can’t afford to lose power for extended periods such as medical facilities, banks etc
