PEG: Overview
• Lean and simple to install substructure with 8deg East-West
fixed-tilt orientation
• Three main parts: Rod, base plate and top plate
• Extremely high area utilization of ~7 sqm per kWp
• Low profile, with ~95cm above ground
• Very light BOS, ~11-12kg per kWp
• Already installed in MWp scale in 3 continents

PEG: Mechanical BOM - Items
Head
Plate
• Each module is connected to 4 rods, one in
each corner.
• A ground plate and a top plate connected to
each rod
• A single Stiffening Bracket installed at each
corner to connect the corner rod to nearby rod
to improve mechanical strength

PEG: Site Requirements
•
Recommended slopes *:
• North-south: Flat or 20 ~ 3% max toward the sun
• East-West: 20 ~ 3% max *
• No rocks or underground infrastructure up to 1m below
ground is preferred
• Soil type: Cohesive (e.g. sandy-clay, clayey silt) & noncohesive soil (e.g. sand or sand-gravel)
• Land required: ~7 Square-meter per kWp

PEG: Foundations
•
•
•
•
No foundations required in the DC plant. rods rammed to the
ground
Ramming depth is ~80cm, TBD based on pull-out tests and the
soil type
Minimum ramming depth of short & long rods: 50cm & 65cm
Special rods with screw-type edge allows very shallow
foundation of only ~40cm
Standard PEG system with rods at ~80cm below ground
~80cm
~80cm

PEG: Packing
•
•
•
Substructure weight: ~11-12kg per kWp for MWp scale
system, including accessories (without modules & inverter)
A single 40ft container per ~1.5MWp PEG substructure
Substructure for 10kWp system fit in ~180x100x60cm box
10kWp PEG kit substructure package, including inverter

PEG: Installation Process
•
•
Simple, safe and fast installation
Labor: ~1 man-hours / kWp for all DC plant (inc.
surveying, substructure, modules, cabling & logistics until & inc. inverters)
•

PEG: Summary of EPC Cost Saving
Benefits PEG vs other solar systems:
• 65% substructure material cost saving
• Over 50% saving in transportation costs due to
significantly less substructure material
• DC plant installation costs saving due to the simple
installation process
• Over 50% reduction of labor costs
• No foundations required
• No heavy machinery required
• Higher safety through much simpler assembly, e.g. no
working-on-heights
