This document discusses key considerations for solar photovoltaic plant design, including technology selection, module selection, common module defects, tests for modules, inverter selection criteria, mounting structures, site layout, tilt angle, electrical system layout, system monitoring, and grid connection components. It provides specifications for modules and inverters. The goal is to design a plant that uses defect-free modules and optimizes annual energy yield based on factors like latitude, solar resource distribution, and component selection.

19. Site layout
 Designing row spacing to reduce inter-row shading and
associated shading losses.
 Designing the layout to minimise cable runs and associated
electrical losses.
 Creating access routes and sufficient space between rows to
allow movement for maintenance purposes.
 Choosing a tilt angle that optimises the annual energy yield
according to the latitude of the site and the annual distribution
of solar resource.
 Orientating the modules to face a direction that yields the
maximum annual revenue from power production. In the
