The Installation of photovoltaic arrays (PV)

Descriptions

- The proposed scheme comprises the installation of photovoltaic arrays (PV) together with full replacement of the existing central distribution as part of the works on the British High Commission's Main Compound Site in Banjul, The Gambia. The works include: - Installation of 2 No. new Photovoltaic arrays, ground mounting systems, all associated cabling and underground ducting, AC/DC services, including local energy supplier equipment, submitting applications, local energy supplier liaison and export metering systems. - Replacement of the existing electrical main switchgear assembly to enable incorporation of photovoltaic arrays and battery energy storage facilities. - Provision of battery storage facility situated in the generator building storage room adjacent to the main electrical switch room. - Provision of cooling system including associated power supplies within the new battery storage room to ensure the battery units remain at optimum temperatures. - Provision of mechanical ventilation situated in the generator building storage room adjacent to the main electrical switch room. - Survey ground structure / integrity to confirm that the chosen areas can support the new photovoltaic installation. - Survey the indicative cable ducting route from the proposed inverter positions to the main electrical switch room. Provide new trenching, for ductwork. - Upgrades to the existing switch room and proposed battery storage room that shall include lighting, emergency lighting, fire alarm works and lithium-ion gas detection. - Provision of earthing, bonding and lightning protection system, as required. - Employ a Lightning Protection Specialist to provide a Lightning Protection / Earthing installation to bond any solar steel support frameworks and switchgear as part of these works. - Provision of Builders work holes and fire stopping of service penetrations. - Testing and commissioning of the new electrical switchgear, battery storage and photovoltaic equipment. - Witness testing of the existing generators to ensure change-over functionality is operational. - Testing and commissioning of the new electrical switchgear, battery storage and photovoltaic equipment. - Witness testing of the existing generators to ensure change-over functionality is operational.
