18. It started here….
18

19. We built 22 retail sites across 7 states
19

20. We Designed the Long Island Solar Farm

21. Then we did 100MW across 25 sites
21

22. In 2011, we designed a PG&E Solar Farm

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

24. Now, we want to help you with a lifetime of green energy.
