Case Study: Frank Toyota

Sustineo Construction acted as GC and EPC for four car dealerships in National City, CA. The largest system at 468 kWp, was a combination of ballasted roof mount dual tilt modules and carport canopy shade cover mounted solar. Scope of work included design and permitting with the city, construction, test and commissioning, and included a lobby display of real-time PV production.

IKER-LAIN CARRASCOSA VACASHead of the PV Technical Office, Isolux Ingenieria USA

It’s been well over six months since our Redlands Headquarters solar PV installation came on line. Since the system was energized, it has been producing nearly 25% of our site’s electricity and has been problem-free. Thank you for helping to make this first landmark solar project an enormous success!

BRYAN GORDONSustainable Programs Manager, Southern California Gas Company

I would like to take this opportunity to express my appreciation to (Southern California Edison) about the design team Sustineo for a job well done on the subject contract. Your overall rating is “Outstanding” as reflected on the Navy’s performance evaluation. The Navy needs good responsive contractors and Sustineo is an outstanding example for other contractors to emulate. Thank you for performing in such a professional manner. It was a pleasure doing business with your company.
