solar energy advantages and disadvantages
Answers
1. Solar energy is free although there is a cost in the building of ‘collectors’ and other equipment required to convert solar energy into electricity or hot water.
2. Solar energy does not cause pollution. However, solar collectors and other associated equipment / machines are manufactured in factories that in turn cause some pollution.
3. Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid.
4. Many everyday items such as calculators and other low power consuming devices can be powered by solar energy effectively.
5. It is estimated that the worlds oil reserves will last for 30 to 40 years. On the other hand, solar energy is infinite (forever).
1. Solar energy can only be harnessed when it is daytime and sunny.
2. Solar collectors, panels and cells are relatively expensive to manufacture although prices are falling rapidly.
3. Solar power stations can be built but they do not match the power output of similar sized conventional power stations. They are also very expensive.
4. In countries such as the UK, the unreliable climate means that solar energy is also unreliable as a source of energy. Cloudy skies reduce its effectiveness.
5. Large areas of land are required to capture the suns energy. Collectors are usually arranged together especially when electricity is to be produced and used in the same location.
6. Solar power is used to charge batteries so that solar powered devices can be used at night. However, the batteries are large and heavy and need storage space. They also need replacing from time to time.
ADVANTAGES OF SOLAR ENERGY :-
♥ Solar energy is truly a renewable source of energy , it's available to us for about 5 billion years .
♥ As the solar energy that's generated can be used for several purposes , your electricity bill can be reduced .
♥ It can be used for various purposes and also can be integrated into the materials used for buildings .
♥ They don't generally require a lot of maintenance , once they are installed u can spend less on maintaining it and repair work .
DISADVANTAGES OF SOLAR ENERGY :-
♥ The initial cost of purchasing the solar system is very high , including solar panels , inverter , battery etc...
♥ During the cloudy and rainy days the efficiency of the solar system drops out , so much energy can't be generated .
♥ The storage cost is generally very expensive , there is something called grid solar system which can be charged during the daytime so that the energy is used at night .
♥ The more energy u need the more solar panels u have to install , if u can't afford much space ... then you can get only limited energy .
♥ The transportation and installation of solar system have been associated with the emission of green house gases , thus creating pollution .
