Solar Panel Knowledge Quiz

1. People use solar power mainly because they...

Do not cause noise pollution

Do not cause air pollution

Do not cause land pollution

All of the above

Solar power is used mainly to reduce all types of pollution because it runs on a clean energy source. Therefore, "All of the above" should be the correct answer.

Explanation

Solar power is used mainly to reduce all types of pollution because it runs on a clean energy source. Therefore, "All of the above" should be the correct answer.

2. Solar energy is a desirable alternative to fossil fuels and other depletable resources because:

They are pollution and noise free

They require no movable parts

The sun is an inexhaustible source

All of the above

Solar Power was introduced as an alternative source of energy not because of any single advantage, but because of its variety of advantages it provides. It does not cause any form of pollution, requires no movable parts to operate and is a renewable source of energy. Therefore, the correct answer is "All of the above"

Explanation

It does not cause any form of pollution, requires no movable parts to operate and is a renewable source of energy. Therefore, the correct answer is "All of the above"

3. The most important reason why Singapore should use solar power more than any other countries is

Singapore has high energy consumption.

Singapore is very sunny

Singapore is unable to rely on alternative sources of energy

All of the above

Singapore has a high energy consumption in order to maintain the industries, businesses and services in Singapore to ensure a thriving economy. Singapore also receives large amounts of sunlight throughout the year, except from around November to January, therefore solar power can easily maximize its use in Singapore. Singapore is also unable to rely on alternative sources of energy such as nuclear energy (because of its risks and costs), and is unable to use wind or water to generate energy as Singapore does not have natural resources and land. Therefore, "All of the above" is the most suitable answer.

4. One reason why Singapore should not use solar power but other countries can afford to is

Solar cells and solar panels are expensive

Solar power can only be used in the day

Solar powers have low energy production

Solar panels take up a large amount of land space

Singapore has a land area of only approximately 700 square kilometres in 2010 among which two-thirds of land is already occupied by water catchment areas. Because solar panels have low energy production, many solar panels are needed to ensure that sufficient energy is produced to meet the specified needs. Therefore, Singapore does not use solar energy because it takes up too much land space, exacerbating the problem of land constrain in Singapore.

5. Based on your knowledge, what do you think is the main disadvantage of using solar power in HCI?

Strain on school resources

Takes up a lot of space

Insignificant amount of energy produced

Requires regular maintenance and cleaning

Solar panels are located on the roofs of HCI which means that solar panels simply maximize the land space in HCI instead of taking up additional space. A significant amount of energy is produced as the estimated electricity generated is 25,550 kwh per year, amounting to $7200 equivalent of savings per year. Maintenance and cleaning is just a small effort on the school's part which can easily be settled by deploying cleaners to do additional duties. However, solar panels are extremely expensive, therefore is a strain on school resources.
