Project Case Study: Manufacturing
A near-megawatt rooftop system for a plastic injection molding facility: industrial-scale commercial solar mounted with a Solar Strap ballastless system and built around the facility's high energy demands.

Plastic injection molding is energy-intensive by nature: heaters, hydraulics, chillers, and compressed air running through long production schedules. Electricity is a direct input cost to every part that comes off the line, which means utility rate increases land straight on the margin.
Demand charges compound the problem: they make up 30-70% of many commercial electric bills, and heavy machinery is exactly what drives them.
This La Verne facility needed a large-scale system that could offset high industrial energy demands without compromising the roof it sits on. The answer was 793kW of rooftop solar on a Solar Strap ballastless mounting system.
Delivered as a full EPC scope: engineering, procurement, construction, permitting, utility interconnection, and commissioning, with Keen accountable for the outcome end to end.
A near-megawatt array sized against the facility's high industrial energy demands, spanning the manufacturing building's rooftop.
A ballastless attachment approach that secures the array without the added dead load of ballast weight, protecting the roof's structural capacity.
Interconnection engineered by in-house C-10 crews into a facility where production cannot stop for the installer's convenience.
Ballasted systems hold panels down with weight, and at 793kW that weight is substantial. The Solar Strap ballastless system attaches the array without that added dead load, a deliberate choice for a large industrial roof where structural capacity is worth protecting for the system's full service life.
A facility with heavy daytime production consumes solar energy as it is generated, the configuration that holds up best under NEM 3.0's reduced export compensation. High daytime consumption is precisely the load profile where commercial solar math works hardest in the owner's favor.
Keen's crews are state-certified Journeymen and Apprentices, and our projects are prevailing wage, AB 2143, and DIR compliant. Getting labor compliance wrong is expensive. Our guide to AB 2143 and prevailing wage explains what is at stake, and our FEOC requirements guide covers what it now takes to actually claim the federal credit.
We do not publish client financials, and industry ROI estimates often miss by 20-30% because they use generic assumptions. Here is the published market math, labeled as what it is:

A real answer requires your interval data and rate schedule. We show you the math, not marketing promises.
If you run a manufacturing, distribution, or industrial facility, this project demonstrates that near-megawatt rooftop systems are buildable on working industrial buildings; that mounting choices can protect your roof's structural capacity instead of consuming it; and that an EPC contractor with in-house electrical crews can deliver at industrial scale without production interruptions dictating the outcome.
