SOLAR MOUNTING SYSTEMS

PEG® EW System Overview:

PEG® EW System Overview

The PEG® provides a unique simplified high-density ground mount solution that produces 225% more land yield versus trackers and fixed tilt systems. The low profile 8-degree tilt design requires minimal spacing between modules creating an ocean of solar panels.

The PEG® is very mobile, light weight, simple to install with only hand tools, no DC trenching, no foundations, no concrete and requires minimal land giving you flexibility of choosing where to install. The PEG® provides a more sustainable solution for solar at a significantly reduced CAPEX.

Extremely high land use. Comparison per acre:
- 3 times higher DC vs trackers, ~ twice higher vs fixed-tilt
- 225% higher yield vs trackers & other fixed-tilt systems
Extremely cost-effective CAPEX (supply and installations)
Low profile & shallow foundations, <1m (3.3ft) above & below ground
Very light system, ~9 kg (~20lb) per kWp (540W modules)
Proven globally, over 420MWp installed
Patented design

THE PEG® EW SYSTEM, THE MODULES COVERING ~95-98% OF THE DC AREA WITH NARROW GAPS BETWEEN THE BLOCKS

DESIGN CHARACTERISTICS

Only 3 items: Steel rod, Ground plate and Top plate
Modules at 8 deg E-W tilt, laid on the Top plates under the module’s corners
Optional anchor rods for soft soil or need for shallow foundations

DESIGN ROBUSTNESS

Wind Tunnel tests successfully completedby IFI in Germany, in 2012 & 2020
Max wind speed TBD per country, e.g.ASCII 7-10: ~185mph (~300km/hr) *
Max snow load: ~50-60PSF (Pound perSquare Foot) *

* The wind and snow limits are subject tosite-specific calculated loads, determined mainly by the site wind speed, snowload and local code. The PEG® EW design might require additional support, subject to the max loads allowed by the module manufacturer and the mechanicalanalysis of the substructure.

LAND USE

Extremely high land use:

~1.9MWp/Hectare
(~0.8MWp/Acre)
with ~550W modules

Flexible system design allowing very high land use, also on sites with irregular shape (e.g. narrow and long or not-rectangle)

The system’s orientation can be alighted to the site boundaries (NOT to the East-West direction) to maximize the land use, with NO impact on the system’s yield, due to the low modules’ tilt

INSTALLATION METHODOLOGY

CONSTRUCTION PRACTICES ARE IRRELEVANT

Low quantity of material and labor
Without: Concrete, trenching and heavy machines
Working height: ~1m (~3.5ft)
Lightweight substructure, <3kg (7 lb) per item

PEG®: CAPEX COSTS SAVING VS OTHER SYSTEMS

Cost Factor	Saving
Material	Substructure: ~50-65% less, DC cables: ~20-30% less
Logistics	~50% less due to far lower substructure quantities and weight
Labor	~50% less due to less labour time (hr/MW) & skilled labour (avg. hr cost)
Construction material	No concrete & sand is required for foundations or DC trenching
Machinery & tools	No heavy machinery is required (e.g. ramming, trenching, concreting). Only small forklift for site logistics and hand tools required.
Site operation	~30-50% less installation time, leading to saving of site operation costs, e.g. management, safety & security labor & equipment, consumables, Etc.
Safety	Far simpler installation process, e.g. without working on heights and without heavy substructure items, leading to significant less OHS effort and injury risks
Land	DC area ~50-65% smaller a Lower land acquisition / rent costs, lower installation costs, shorter perimeter fence
