Solar Panels procurement guide
Photovoltaic modules are supplied by output class and technology for grid-tied, hybrid and off-grid systems, with mounting selected for the roof or ground condition. Electrical equipment must be selected as part of a system, using load, network, protection, environment and applicable project requirements.
System role and load
The stated applications are Commercial rooftop generation, Ground mounted solar farms, Off-grid and hybrid systems and Institutional and rural electrification. Provide the system role, connected loads, duty, redundancy, future capacity and interfaces with existing equipment.
Ratings, compatibility and acceptance
Compare proposals against Total system size required in kWp, Roof or ground mounting arrangement, Available area and orientation, Grid-tied, hybrid or off-grid configuration and Delivery and installation requirements. Require source-specific drawings, datasheets, protection or coordination information and the test/standard evidence called for by the project.
Installation, protection and support
Confirm enclosure and environmental conditions, cable/termination interfaces, dimensions and weights, transport protection, site access, installation boundaries, testing, commissioning, training, warranty expectations and spare components.
