Project development process for grid connected rooftop solar PV projects in India

In this blog, we are going to discuss about general project development process for grid connected rooftop solar PV projects in India. The general set of stages that most project development processes follow, which includes :
(i) Project Planning/ Preparation
(ii) System Design
(iii) Implementation
(iv) Operation & Maintenance

PROJECT PLANNING
SYSTEM DESIGN
IMPLEMENTATION
O&M

Feasibility Assessment

§  Technical &
financial pre-
feasibility 
assessment

Initial Cost & Return 
analysis, Evacuation 
Feasibility etc.

§  Feasibility Report
