Although more expensive, lithium-ion batteries provide longer life cycles, higher efficiency, and better performance in a variety of environmental conditions.

Another crucial aspect of battery selection is compatibility with the entire system, including the solar panel and charge controller. Charging requirements, discharge rates, and the operational voltage of the system should all align to ensure seamless functionality. Ultimately, understanding different battery technologies and performance characteristics will enable better decision-making.

5. CONFIGURING LIGHTS: SERIES OR PARALLEL

The method in which solar lights are connected can significantly impact performance and functionality. The two primary configurations are series and parallel wiring. Each configuration has its unique advantages and scenarios where it is more suitable.

In a series configuration, lights are connected end-to-end. This means that the total voltage requirement equals the sum of individual light voltages. This setup can be beneficial when a limited voltage source is available. However, one significant drawback is that if one light fails, it breaks the circuit, causing all lights to go out.

Conversely, a parallel configuration connects lights individually to the power source, ensuring that if one light fails, the others remain illuminated. This method often allows greater flexibility in the arrangement of lights and guarantees they receive the same voltage, which can enhance performance consistency.

Selecting between these configurations depends on the requirements of the installation site. A proper assessment of power needs, voltage ratings, and desired reliability must guide the decision.

6. MAINTENANCE AND CARE
