Answer :
Final answer:
A solar panel installer uses a heavy rubber mallet to securely fasten panels to rooftops without causing damage, ensuring the panels are correctly positioned for optimal energy absorption. Correct answer is option A.
Explanation:
A solar panel installer uses a heavy rubber mallet to securely fasten panels without damaging them. This technique is crucial in installations on rooftops, particularly for residential applications, where precision and care are paramount to ensure the integrity of the solar panels and the roof structure. Solar panels, such as those made from gallium-arsenide in rigid formats for better power efficiency, are commonly installed at angles that optimize sun exposure, often equaling the site's latitude and oriented toward the south for maximum energy absorption. Ensuring proper fastening of panels without causing damage is a delicate balance that requires both knowledge of solar panel design and the right tools, like a heavy rubber mallet, which allows for force to be applied in a way that mitigates risk to the delicate solar cells.
