Section outline

    • Welcome to SS3, the final and most advanced stage of your training. This term, we will move
      beyond basic installation and troubleshooting to explore emerging technologies, national policies,
      and the business/environmental context of solar energy.
      Before we proceed, we must conduct a thorough review of the foundational knowledge from SS1
      and SS2. This recap is essential for understanding the advanced concepts to come.

      • Core Components and Functions

        • Solar Panel (PV Module): The "generator." Composed of photovoltaic cells (usually
          silicon) that convert sunlight (photons) directly into Direct Current (DC) electricity via the photovoltaic effect.
        • Charge Controller (Solar Regulator): The "brain" for battery-based systems.
          • Function: Regulates the voltage and current coming from the panels to the
            batteries, preventing overcharging and deep discharge.
          • Types:
            • PWM (Pulse Width Modulation): Cheaper, less efficient. Acts like a
              simple switch.
            • MPPT (Maximum Power Point Tracking): More expensive, highly
              efficient (up to 30% more power). It's a smart DC-to-DC converter that
              matches the panel's voltage to the battery's voltage for optimal charging. MPPT is the professional standard.
        • Battery (Energy Storage): The "storage tank." Stores DC energy from the panels for use
          at night or during cloudy weather.
