    Study Notes

    Renewable Energy

    • Renewable energy is derived from the earth's natural resources that are not finite or exhaustible, such as wind and sunlight.
    • It is an alternative to traditional energy that relies on fossil fuels, and tends to be much less harmful to the environment.

    Solar Energy

    • Solar panels convert solar/photon energy into electricity through the photovoltaic effect.
    • When a photon hits a photovoltaic/solar cell device, its energy is transferred to the electrons in the material, producing an electric current.

    Solar PV Categories

    • There are two main categories of solar PV:
      • Grid-connected (GCPV)
      • Stand-alone/Off-grid (SAPV/OGPV)

    Grid-Connected PV (GCPV)

    • A GCPV system is an electricity generating solar PV power system connected to the utility grid.
    • Designed to operate with the electric utility grid.
    • Primary components include PV arrays and BOS (Balance of System) components.
    • Examples of GCPV systems include rooftop installations (e.g., 4.14kWp in Penang).

    Stand-alone/Off-grid PV (SAPV)

    • A SAPV system is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system.
    • Designed to operate independent of the electric utility grid.
    • Commonly installed in remote locations with no electric utility grid.
    • Supply DC and/or AC electrical loads.
    • Can be configured in several ways, such as direct-coupled systems or hybrid systems with battery energy storage.
    • Examples of SAPV systems include hybrid systems (e.g., 276kWp in Semporna, Sabah).

    Malaysia Renewable Energy Target

    • The Ministry of Energy and Natural Resources of Malaysia set a target to reach 31% of RE share in the national installed capacity mix by 2025.
    • This target supports Malaysia's global climate commitment to reduce its economy-wide carbon intensity by 45% in 2030 compared to 2005 levels.
