Which type of battery is commonly used in solar power systems?

• A. Lithium-ion
• B. Lead-acid
• C. Nickel-cadmium
• D. Alkaline

Answer: (B)

The commonly used battery type in solar power systems is lead-acid. These batteries have a long history of use in various applications, including solar energy storage, due to their reliability and comparatively lower initial cost. Lead-acid batteries can handle deep discharges and are quite robust against the fluctuating demands of solar energy systems. Moreover, their well-established manufacturing process means replacement batteries and parts are widely available, making maintenance more manageable for users. Lead-acid batteries also have the advantage of being recyclable, which is beneficial from an environmental standpoint—an important consideration in the context of sustainable energy systems. While lithium-ion batteries are increasingly popular due to their higher energy density and longer lifespan, they tend to be more expensive than lead-acid batteries and are not as commonly the first choice for all solar applications. Other battery types like nickel-cadmium and alkaline are less favored for solar energy storage because they are generally not as cost-effective or efficient as lead-acid and lithium-ion options.
