Board & Management

The Board confines itself to making broad policy decisions and exercising a number of reserved powers to consider and approve financial statements in interim report and annual report and to consider the dividend policy and dividend amount and to monitor the corporate governance of the Company.

The Board confines itself to making broad objectives and strategic decisions while delegating responsibilities for more detailed consideration to various committees including the Strategic Planning Committee, Audit Committee and Remuneration Committee which are established under the Board. Each of these committees has its respective terms of reference and reports its work to the Board regularly and makes suggestions on the matters under discussion. With delegated authority by the Board, the senior management will implement those strategic plans, policies and business plans conferred by the Board and/or the Committees.

The independent non-executive directors (INEDs) play an important role in corporate governance. Half of the members of the Strategic Planning Committee are INEDs, and the Audit Committee and Remuneration Committee comprise members of all INEDs. In this connection, the INEDs provide their independent opinions on matters including strategy, corporate performance and accountability at various committee meetings and Board meetings.

    In the centralized grid-connected photovoltaic power system with dispersed inverters, the power transmission line which collects the AC power output of each inverter

  • Balance of System

    In the photovoltaic power system, the equipment and systems other than PV modules, including inverters, batteries, combiner-boxes,

  • Maximum system voltage

    The maximum withstand voltage of PV modules.

  • Point of common coupling(PCC)

    The coupling joint for more than one user in the grid.

  • Point of interconnection(POC)

    Also known as access point. It means the node of the transformer which is directly connected to the grid for PV power stations connected to

  • Islanding

    The state wherein the PV power station still supplies power for certain load in the public grid when disconnected from the grid.

  • Intentional islanding

    Islanding which occurs in an intentional way according to the pre-set control strategy.

  • Unintentional islanding

    Islanding which occurs in an unintentional and uncontrolled way.

  • Anti-islanding

    Preventing occurrence of unintentional islanding.

  • Peak Sunshine Hours

    The equivalent number of hours when the total solar irradiance in a certain time period equals that of a continuous light source with irradiance of 1000W/m2

  • Annual Peak Sunshine Hours of PV Station

    The equivalent number of hours when the total annual solar irradiation received by the PV array surface is converted under standard test conditions (irradiance: 1000W/m2).

  • Direct Normal Irradiance(DNI)

    The amount of radiation received by a surface perpendicular to the rays

  • Capacity of Installation

    Sum of nominal power (in Wp) of PV modules installed in the PV power station.

  • Solar time

    A timing system based on solar hour angle. In solar time, the moment when the solar disk is at the local place’s upper transit is zero hour.

  • angle of incidence

    The angle formed by a ray incident on a surface and a perpendicular to the surface at the point of incidence.

  • azimuth angle

    The included angle between the projection of the line from the center of the sun to the observation point on the ground on the local horizontal plane

  • solar elevation angle

    The included angle between incident sun rays and the horizontal plane.

  • solar declination

    The included angle between the line from the center of the Earth to the center of the Sun and the equatorial plane (such angle in the Northern Hemisphere is positive)

  • hour angle

    The included angle between the projection of the Sun on the equatorial plane at a certain moment and the projection of the Sun on the equatorial plane at noon.
