Which two properties of a solar cell material would generally be most important to a business owner who wants to install rooftop solar cells on a building?

Answer 1

When considering the installation of rooftop solar cells, a business owner would typically prioritize the following two properties of solar cell materials:

1. Efficiency: The efficiency of a solar cell refers to how effectively it converts sunlight into electricity. Higher efficiency means that a solar panel can generate more electricity from a given area, which is crucial for rooftop installations where space may be limited. Business owners would want to maximize the energy output to make the most of their investment.

2. Durability and Longevity: The durability and expected lifespan of the solar cell material are critical for minimizing maintenance costs and ensuring long-term performance. Solar panels are typically a long-term investment, and materials that can withstand environmental factors (like UV exposure, temperature fluctuations, and weather conditions) will be more appealing to business owners looking for reliable and sustainable energy solutions.

These properties directly affect both the performance and the return on investment for a solar installation, making them key considerations for any business owner.
