The document outlines the essential engineering submittals required for the design and implementation of solar photovoltaic (SPV) power plants, including detailed specifications and construction methodologies. It categorizes the deliverables into civil and electrical components, listing various crucial aspects such as land analysis, major equipment selection, and layout designs. Additionally, the document emphasizes the necessity of clear drawings and relevant technical specifications to facilitate efficient construction and capture site-specific changes.

1. Engineering Submittal Essential for a SPV Power Plant
Design & Engineering is an integral part of the implementation of the SPV power plants.
Engineering drawings & documents convey specifications, construction methodology, dimensions,
tolerances etc capturing the scope of works and presenting a first-hand idea on the final by product
that would be constructed.
Typical Master Deliverable list can be divided in two broad categories of Civil & Electrical which would
each entail the following:

The drawing should be able to serve site related changes, capture details of vast and remote access,
and be clear in nature to aid faster construction.
Apart from the above drawings the developer should also seek out for relevant technical
specifications, quality assurance plans, design basis reports, generation yield assessments,
implementation schedules & bill of material with quantities.
