The document provides details of the proposed 100kWp solar PV system to be installed at Lady Andal School. It includes a site overview, system design, module layout, simulation results, cable and equipment layouts. Foundation designs are shown for 4 blocks. Installation steps and a timeline are outlined showing work started in April and was expected to be completed by May. Load details are provided in an appendix showing the existing electrical loads across school and residential sections totaling 223,250 Watts.
