Understanding Solar Energy Concepts

Solar energy is a renewable power source that uses the sun's energy to generate electricity. Photovoltaic cells in solar panels capture sunlight and convert it into electrical energy. Solar energy is abundant, clean, and does not produce emissions. It can be generated even on cloudy days and stored for later use. Solar systems can power homes, cities, and remote areas without large infrastructure, offering a sustainable solution for energy needs.

What is the primary function of photovoltaic cells in solar panels?

• To heat water using solar power

• To store sunlight for later use

• To convert sunlight into electrical energy

• To reflect sunlight away from the panel

Which of the following is a major advantage of solar energy?

• It is limited to daytime use only

• It requires burning fossil fuels

• It is abundant and clean

• It produces high emissions

How do solar panels perform on cloudy days?

• They produce less energy but still function

• They stop working completely

• They require additional fuel to operate

• They only store energy without producing it

What is a key benefit of solar energy systems in remote locations?

• They need large infrastructure to operate

• They can function without relying on large infrastructure

• They are only effective in urban areas

• They require constant maintenance

What happens to the extra energy produced by solar panels?

• It is converted back into sunlight

• It is stored in batteries for later use

• It is used to power other solar panels

• It is wasted if not used immediately
