Negatives of solar energy

Hi buddy we are talking about only solar energy positive thing, do you know there is so may Negatives things also of solar energy , can you here any one discuses both points of solar energy ??

We all know Solar energy is radiant light and heat from the Sun harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis.

As you want here I am talking about on both points of Solar energy

Solar energy positives things

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).

Solar energy negatives things
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.
