     • Thin-Film: Least efficient and generally bulkier, but can be more flexible and durable. Less common in portable generators.

2. Battery: The battery stores the electricity generated by the solar panel. The capacity of the battery determines how long you can run your devices without sunlight. Look for deep-cycle batteries designed for repeated charging and discharging.

   • Types of Batteries:
     • Lead-Acid: The most affordable option, but also the heaviest and require maintenance. Not ideal for portable setups.
     • AGM (Absorbent Glass Mat): A type of lead-acid battery that is sealed and maintenance-free. A good compromise between cost and performance.
     • Lithium-Ion: Lightweight, high capacity, and long lifespan, but also the most expensive. The best choice for portability and performance.

3. Charge Controller: This crucial component regulates the voltage and current flowing from the solar panel to the battery, preventing overcharging and damage. Choose a charge controller that is compatible with your solar panel and battery type.

   • Types of Charge Controllers:
     • PWM (Pulse Width Modulation): Less expensive, but less efficient. Suitable for smaller systems.
     • MPPT (Maximum Power Point Tracking): More efficient, especially in low-light conditions. Worth the investment for larger systems.

4. Inverter: The inverter converts the DC (Direct Current) electricity from the battery into AC (Alternating Current) electricity, which is what most household appliances use. Choose an inverter with enough wattage to power the devices you plan to use.
