For breaking down solar farm costs, the following should be considered. The balance of system (BoS) costs can be broken down into: three broad categories (non-module and inverter hardware, installation costs, and soft costs). Which can brake down in more detailed sub-categories - non-module hardware costs, cabling, all direct current (DC) components, such as DC cables, connectors and DC combiner boxes, all AC low voltage components, such as cables, connectors and AC combiner boxes. Racking and Mounting: Complete mounting system including ramming profiles, foundations and all material for assembling material necessary for mounting the inverter and all type of combiner boxes. Safety and Security: fences, camera and security system and all equipment fixed installed as theft and/or fire protection. Grid Connection: all medium voltage cables and connectors, switch gears and control boards, transformers and/or transformer stations, sub-station and housing and Meter(s). Monitoring and Control: monitoring system, meteorological system (irradiation and temperature sensor) and supervisory control and data system. Installation Costs, inspection (Construction Supervision).
