Poway is a small city with one of San Diego County's largest concentrations of light industrial and R&D space. The Poway Business Park holds more than 500 businesses and 18,000 employees across over 9.5 million square feet — and vacancy has run under 3%. That is an unusual density of exactly the building type solar suits best.
Because it is built almost entirely from the building type solar works best on: large flat-roofed light industrial, manufacturing and R&D premises with daytime process loads and the electrical service to support a sizeable array.
Indigo Energy and Solar Inc provides commercial solar installation, battery storage and EV charging in Poway, California. Licensed electrical contractor, IBEW Local 569 signatory, with nine completed school installations across San Diego County ranging from 109.6 kW to 487.7 kW.
The park was designed for light industrial and manufacturing, warehousing and distribution, and research and development. Those three categories cover most of what we would install on here.
General Atomics Aeronautical Systems is headquartered in the park. Precision manufacturing carries steady, daylight-weighted process loads with climate and cleanliness requirements that make energy a fixed operating cost rather than a variable one.
Cohu, Delta Design and HM Electronics are among the park's established manufacturers. Test, assembly and instrumentation facilities run controlled environments with consistent load through the working day — close to an ideal solar profile.
Sysco operates from the park. Distribution buildings combine very large flat roofs with refrigeration load, which is the combination that produces the strongest payback of anything we install on.
Geico Direct and CoreLogic Credco run substantial operations here. Office loads are lighter per square foot than industrial but very predictable, and large single-storey office roofs often carry more array than the building needs.
Pomerado Hospital serves the Poway area. Healthcare campuses run constant loads that cannot be shed, so the case combines cost reduction with genuine resilience value from paired storage.
Poway Unified School District is among the area's largest employers. Districts can now access the federal credit through direct pay, and our completed work in San Diego County is predominantly school installations.
Most commercial solar guidance is written for a generic building. Poway is unusual in that the majority of its commercial floorspace sits in one planned park built for a specific purpose.
That means the roofs tend to be flat, large and structurally straightforward; the electrical service tends to be sized for industrial process rather than office use; and there is usually somewhere sensible to put switchgear. Those three things together are most of what determines installation cost per watt.
It also means a company moving within the park can generally assume solar is viable — which is not true everywhere in the county.
Under NEM 3.0, energy exported to the grid earns considerably less than energy imported costs. The design goal is therefore self-consumption, not maximum capacity.
A single-shift manufacturer running roughly 7am to 5pm is close to the best possible match for a fixed rooftop array — the generation curve and the load curve overlap for most of the productive day.
Two-shift and continuous operations change the calculation: more of the load sits outside generating hours, which usually strengthens the case for storage rather than weakening the case for solar.
Section 48E provides a 30% federal credit on qualifying commercial solar, and facilities below 1 MW are exempt from prevailing-wage and apprenticeship requirements, so they reach the full rate automatically. Nothing here is tax advice — we work alongside your accountant.
For a manufacturer with real federal tax liability, that credit plus accelerated depreciation is what makes the payback work. For Poway Unified, or a nonprofit, the route is different: Elective pay, commonly called direct pay, lets eligible tax-exempt and governmental organisations receive the value of that credit as a payment from the IRS rather than as an offset against tax owed.
Most are. The park's building stock is largely flat-roofed light industrial, which is the most cost-effective surface to install on. The variables are roof condition, structural capacity and where your electrical service sits — all of which we check before quoting.
Yes, though the design changes. A larger share of your load falls outside generating hours, so we model storage against the evening block rather than sizing the array alone. It usually strengthens the case for storage, not against solar.
It depends on roof area against consumption, and we will not guess at it. Twelve months of SDG&E bills lets us model it properly for your building rather than quoting a park-wide average.
Only at 1 MW and above. Below that a facility is exempt and receives the full 30% federal credit automatically. Effectively every building in the Poway Business Park falls below that threshold.
That is the strongest case we see. Refrigeration load is large, constant and daytime-weighted, so a very high proportion of generation is consumed on site rather than exported.
Yes, through direct pay — eligible tax-exempt and governmental entities receive the credit's value as a payment from the IRS. Most of our completed work in the county is school installations.
Federal tax positions checked against IRS guidance in August 2026. Rules change; nothing on this page is tax advice.
We will look at the roof, the electrical service and twelve months of SDG&E bills, and set out what a system would produce and what the federal credit is worth to your business.
