Quiz On Solar Energy And Solar Panels (HCI)

Solar panels absorb solar energy. Solar energy refers to the energy from the sun that is converted into usable electricity by the solar panels. The panels are designed to capture the sunlight and convert it into electrical energy through a process called the photovoltaic effect. This energy can then be used to power various devices or stored in batteries for later use.

Solar energy refers to the radiant light and heat emitted by the sun. It is a form of renewable energy that can be harnessed and converted into electricity or used for heating and lighting purposes. Solar energy is abundant and sustainable, making it an environmentally friendly alternative to fossil fuels. By harnessing solar energy, we can reduce our dependence on non-renewable energy sources and mitigate the negative impacts of climate change.

A solar panel is a device that converts sunlight into electricity. It is made up of multiple solar cells that are connected together. These cells absorb the sunlight and generate an electric current. The electricity produced by a solar panel can be used to power various devices or stored in batteries for later use. Solar panels are commonly used in solar energy systems to provide renewable and clean energy.

This statement is false because using solar energy does not harm the environment. Solar energy is a renewable source of energy that does not produce harmful emissions or pollutants. It is a clean and sustainable form of energy that helps reduce greenhouse gas emissions and dependence on fossil fuels. Additionally, solar panels can be recycled at the end of their lifespan, further minimizing their environmental impact.

The correct answer is "None of the above" because solar energy has numerous positive effects such as reducing pollution, improving the economy, and benefiting health. Therefore, there is no negative effect associated with using solar energy.

Solar panels have several disadvantages. Firstly, they can be expensive to install and maintain, making them less accessible for some individuals or communities. Secondly, solar panels are not very effective at night or during cloudy days when there is limited sunlight, reducing their overall efficiency. Lastly, solar energy can be unreliable as it is dependent on weather conditions and geographical location. Therefore, all of the mentioned options are valid disadvantages of using solar panels.

The statement is false because it states that the estimated electricity generated by the solar panels in Hwa Chong Institution (HCI) is more than 500,000kWh. However, the correct answer is false, indicating that the estimated electricity generated is not more than 500,000kWh.

Solar panels absorb solar energy by converting photons (particles of light) into electrons. When sunlight hits the solar panel, it excites the electrons in the panel's semiconductor material, causing them to be released from their atoms. These free electrons are then captured and channeled into an electric current, which can be used to power electrical devices or stored for later use. This process is known as the photovoltaic effect and is the fundamental principle behind the functioning of solar panels.

The given answer states that using solar energy harms the environment. This implies that using solar energy has negative effects on the environment, contradicting the question which asks for positive effects. The other options listed in the question - increasing home safety, stabilizing the economy, and reducing pollution - all suggest positive effects of using solar energy.

The estimated saving per year of the solar panels in Hwa Chong Institution (HCI) is $7200. This means that by using solar panels, HCI is able to save $7200 annually on their energy costs.
