After installation, what is one of the main advantages of solar panels?

• A. They require minimal maintenance
• B. They demand frequent repairs
• C. They need constant part replacement
• D. They lose efficiency quickly

Answer: (A)

After installation, solar panels shine because they require minimal ongoing maintenance. The panels themselves have no moving parts and are built to be durable, so once they’re in place you don’t need constant attention. Typical upkeep is mainly occasional cleaning to remove dust or debris and periodic system checks to ensure wiring and the inverter are functioning properly. Many systems come with long warranties (often 20–30 years) and only small, gradual degradations in efficiency over time, rather than rapid losses or frequent repairs. That combination of durability and infrequent service is what makes maintenance after installation so low compared with other energy sources. The other statements don’t fit because solar panels don’t typically need frequent repairs, don’t require constant part replacement, and their efficiency doesn’t drop quickly in the short term.
