The document outlines the steps for installing a solar power plant, including: 1) Site preparation such as inspecting the site, marking points, and leveling or using "disk and roll technique" for irregular surfaces. 2) Post casting by casting poles minimum 1 meter into the ground for mounting panel structures. 3) Mounting panel structures on the posts and checking alignment using a spirit level technique. 4) Connecting cables and installing junction boxes, modules, inverters, and switchgear equipment to complete the solar power plant installation.

3. SITE PREPARATION
Inspection of site - topographical features.
Markings are made as per the prepared design and bored on particular points
In case of highly irregular surface, where leveling cost is too high, disk and roll technique is used
Disk and Roll technique: Soil is locally distributed to maintain minimum embedment, and distance from ground.

4. POST CASTING
Posts are casted on the marked points for mounting panel structures
Minimum Embedment of poles/posts is necessary:1 m
Embedment depends on Soil Strata( after soil testing)
1 m- 1.8 m : Hard Soil ; More than 1.8 m: Soft Soil
Right Entrenchment provides strength to overall structure during heavy wind flow
Width of post : Width: 1 50 mm- 200mm
Initial Post Casting at Site
Ground Level
Min Embedment: 1 m
Width : 150-200 mm

5. MOUNTING OF PANEL STRUCTURES
Panel structures are mounted on the casted posts
Posts are checked for their right vertical alignment using SPIRIT LEVEL TECHNIQUE (a magnetic method)
Technique helps in leveled panel – with zero wave formation and correctly fitted panels on tile structures

6. STRUCTRE ALIGNMENT AND TORQUING PROCESS
Right amount of torque is applied on nuts and bolts -5 turns by hand then, socket driver to finish tightening
Loose fastening : may not withstand wind pressure ; Tight Fastening : may damage the threads of nuts and bolts

7. Cables, Pipes and Joints
CEMENTED PIPE
For easy travelling of vehicles
Ensures strength of pipe for long run
Minimizes losses due to breakage of
pipes
DWC PIPE
Minimizes wear and tear of pipe due to sun
exposure
Augment life of cables and wires
Thus, increasing life-span of park
T-JOINTS +DWC PIPES
Protection of cables @ detailed
level
Enhances longevity of plant
Boost strength of overall
structure

8. Installation of Junction Box
SEALED CAPS
Protection from rodents/insects
Augment life of cables and wires
Note : All photos used in the presentation are actual site photographs.

9. MODULES CONNECTION AND PLACEMENT
Modules in wooden box/iron boxes are placed in front of structures before placing them on tilt structures
Panels are vertically aligned in the packed boxes- after stripping of packed boxes, modules are first stacked.
Stacking of panels becomes necessary as module sheet may damage due to weight on consecutive modules once
first comes out
Safety Gloves and helmets are used for electrical connections of panels
