Completely energy independent No Contribute to environmental sustainability - Employer's requirements Solar panels The manufacturer, type and model of solar panel modules can be selected by the tenderer, subject to approval by PL. The panels shall meet international standards for performance, durability, and safety. Mounting structures The mounting structures shall securely support the solar panels on the desired installation location (e.g., ballasted - rooftop). The structures shall be made of corrosion-resistant materials suitable for outdoor installation. The design shall take into account wind loads, snow loads, and other environmental considerations specific to the installation location - in accordance with the structural information provided. Inverters The solar PV system shall include grid-tied inverters capable of converting the DC power generated by the solar panels into AC power for use or export to the grid. The required manufacturer for this scheme is Solis. The inverters shall have a minimum efficiency of 93 - 96%. The inverters shall meet relevant international safety standards and have built-in protection mechanisms against overvoltage, overcurrent, and other electrical faults. Inverters should be located in well-ventilated spaces that do not exceed the optimum / recommended operating temperatures. Inverters should always be mounted on fire-rated surfaces. Inverters should be installed as close to the solar array as possible to reduce power losses. Inverters should be protected from the elements, positioned away from direct sunlight, rain, snow, etc. Electrical wiring and protection The system shall include appropriate electrical wiring to interconnect the solar panels, inverters, and other components. The wiring shall be sized correctly to minimise losses and comply with local electrical codes and regulations. Protection devices, such as surge protectors, circuit breakers, and disconnect switches, shall be installed as per applicable safety standards. All cabling will be fully supported and secured in cable trays. All cabling will be labelled accordingly, and be weather-proof when external. Wiring diagram, providing the routes of cabling (including external cable runs) will be provided as part of the system O&Ms. Batteries It is not anticipated that there will be a requirement for batteries for this project. Monitoring and control The solar PV system shall incorporate a monitoring and control system to track system performance, energy production, and potential issues. The monitoring system shall provide real-time data on energy generation, consumption, and system health through the Solis interface. Installation and commissioning The solar PV system shall be installed by qualified personnel following industry best practices and local regulations. A comprehensive commissioning process shall be conducted to ensure the system operates as intended and meets performance specifications. All necessary permits and approvals shall be obtained before installation and commissioning. Warranty and maintenance The solar panels, inverters, and other system components shall have a warranty period of: * Solar PV panels - 20 years * Solar PV - inverters - 10 years * Option for extended warranty required. * Mounting system - 20 years The warranty shall cover defects in materials and workmanship and guarantee a minimum performance output over the warranty period. A recommended maintenance plan shall be provided to ensure optimal performance and longevity of the system. The contractor shall ensure that there's a nearby water connection to enable cleaning of the solar PV panels. The contractor shall ensure that there's a nearby electrical connection to enable cleaning the solar PV panels. Solar panel placement: panels should be accessible to clean and inspect without excessive leaning or specialist equipment. Inverter placement: technicians should be able to reach the inverters without difficulty for routine inspections, repairs, or replacements if needed. Always follow manufacturers instructions for specified distances between individual inverter units. The design shall not restrict rainwater run-off from the existing roof structure. Gulleys must be left exposed to enable roof cleaning / maintenance. The contractor shall provide the employer a collateral warranty of 5 years. The contractor will provide a comprehensive operational and maintenance manual, detailed drawings, schematics, handover training with the site team and 12-months of soft landing / servicing support (in the event of issues arising in accordance with the collateral warranty) and electrical compliance checks.
