5. Part A How are light bulbs in a home powered by solar panels located outside the house on its roof?

• The solar panels convert light energy into electrical energy, which is then sent to power the light bulbs.
• The solar panels absorb heat energy from the sunlight and use it to generate light for the bulbs.
• The solar panels capture sound energy and transform it into electrical energy for the light bulbs.
• The solar panels collect mechanical energy and transfer it directly to the light bulbs.

Part B Explain and be specific as possible.
