Question

What are the limitations of solar energy?

1. Collecting solar energy over large areas and converting it to other forms that can be conveniently transported, stored and used in existing equipment is not economical

2. Low density of solar energy as compared to coal, oil and gas

3. Its major applications are photothermal conversion, solar water heating, green housing technology and photo voltaic conversion

Select the correct answer using the codes given below:

1. 1, 2 and 3
2. 1 and 2 only
3. 1 and 3 only
4. 2 and 3 only

Answer 1

Correct Answer - Option 2 : 1 and 2 only

Explanation:

Advantages of Solar Energy:

• Renewable Energy Source: It can be harnessed in all areas of the world and is available every day. We cannot run out of solar energy, unlike some of the other sources of energy.
• Diverse Applications: Its major applications are photo thermal conversion, solar water heating, space conditioning, solar air heating, solar desalination, solar cooker, solar refrigeration, power generation, water pumping, green house technology, generation of fuels, photo voltaic conversion etc.
• Low Maintenance Costs: Solar energy systems generally do not require a lot of maintenance. You only need to keep them relatively clean.

Disadvantages of Solar Energy:

• Capital Cost: The initial cost of purchasing a solar system is fairly high. This includes paying for solar panels, inverter, batteries, wiring, and for the installation.
• Weather Dependent: Its intensity is not constant; it changes from early in the morning to evening. It also changes with different seasons of the year and depends upon the sky conditions.
• Expensive Storage: Collecting solar energy over large areas and converting it to other forms that can be conveniently transported, stored, and used in existing equipment is not economical.
• Problems of designing facilities that can utilize diffused sunlight.

 

∴ Statement 3 is application and advantage of solar energy not limitation.
