Monocrystalline (19 - 20% Efficiency) Polycrystalline (14 - 16% Efficiency) Thin Film (10 – 15 % Efficiency)

Site Analysis

4

• Roof Survey Detailed measurements for accurate as-built

conditions. Survey existing infrastructure and environment

for potential layout and shading impacts

• Electrical Survey – Detailed, visual inspection of existing gear

for interconnection design. – Survey existing site plan for ground-level

equipment locations.

• Structural Survey – Verify that as-built conditions for roof framing

and decking complies with plans. – Identify any potential loading concerns for

array and construction logistics

Energy Modeling

It started here….

19

We built 22 retail sites across 7 states

We Designed the Long Island Solar Farm

21

Then we did 100MW across 25 sites

In 2011, we designed a PG&E Solar Farm

In 2007-2011, we designed 20 Wal-Marts.
