Steps of Site Identification and Project Pre-Feasibility
|Type of solar system:||Ground Mounted Mounted||Support Scheme:||Rajasthan Solar Policy|
The first task towards project development is the identification of a suitable site. The project developer needs to identify a site and check its availability from local Patwari (Clerk level officer at state revenue department).
Site specifications including level of solar irradiation at site, temperature and obstacles which may cast shadows need to be checked initially.
Preferred land orientation is flat; the same must be assessed at this stage. Other criteria include state of drainage system, dust percentage in air and soil strength to support structures.
Along with availability of labor at site, the security and local social support for power plant are important factors and shall also need to be assessed.
Power evacuation feasibility must be checked which would include availability of adequate capacity at the transmission utilities sub- station, distance to sub-station, right of way issues etc. Connectivity to the site (road and rail) and distance from urban areas would also need to be examined for suitability. Accessibility of site by trucks and cranes is critical and must be assessed.
An appropriate Solar PV technology would be identified based on factors like space requirements and availability, available global radiation(GHI), climatic conditions- specially temperature and wind velocity, cost of technology (capital and O&M), projected CUF’s, risks associated with the technologies, need for trained manpower, level of commercial development and performance, availability of technology suppliers/ performance guarantees etc. All of these factors play a critical role in the identification of a suitable technology. For the selected technology, equipment providers are identified and selected.
Preliminary calculations on the overall cost and generation would be assessed to establish project financial viability. This activity is a go/no-go assessment for the project.
