Commercial solar for Arizona facilities
A proposal is only useful when the assumptions are visible. PeakReady Energy helps the people responsible for facilities, operating budgets and long-term asset value determine whether solar fits the property—not whether first-year savings can be made to look attractive.
What we review
• Twelve months of utility and interval data
• Rate schedule, demand charges, escalation and export assumptions
• Roof, parking-canopy or ground-mount constraints
• Production, shading, degradation and curtailment
• Incentives and eligibility verified by qualified advisers
• Capital plan, financing, tax ownership and operating horizon
• Warranties, maintenance, insurance and end-of-term exposure
• Operational disruption, vendor accountability and decision milestones
Who this is for
Owner-occupied commercial buildings, warehouses, light industrial facilities, schools, nonprofits, multifamily common loads, retail and smaller mission-critical operations with usable daytime load.
Project fit
We do not target utility-scale solar. Large data centers are generally not a practical fit because onsite solar cannot supply their continuous load; smaller facilities may benefit from targeted solar and battery resilience.
A credible recommendation shows the base case, downside case and what could change the answer. Savings are estimates—not guarantees. Final engineering, tax, legal, utility, financing and construction decisions require qualified professionals.

Questions to resolve before a solar proposal
For an Arizona facility, the useful question is whether solar, storage or both improve the property’s cost, resilience or power-availability plan after utility, roof, electrical and financing constraints are checked. A proposal should show its assumptions and downside case.
What does an EPC proposal include?
An engineering, procurement and construction (EPC) scope should identify design responsibility, equipment procurement, construction, commissioning, schedule and warranty handoff. Compare the balance of system (BOS)—racking, wiring, conduits, protection and switchgear—as well as modules and inverters.
How does interconnection affect a commercial project?
The utility’s interconnection review and agreement determine the approved connection and operating conditions. Export credits or payments depend on the applicable tariff and approval; do not assume net metering or a retail-rate credit. Service upgrades, transformer availability and switchgear lead times can govern the schedule.
When does solar-plus-storage help?
A photovoltaic (PV) array paired with an energy storage system (ESS) may reduce demand peaks, shift energy use or support engineered critical-load backup. Value depends on interval load data, the rate schedule, battery power and usable duration, controls and operating strategy.
What should a feasibility review check?
Start with 12 months of bills and interval data; rate, demand and export assumptions; main service panel and busbar ratings; transformer and switchgear capacity; roof condition and structural loading; seasonal shading from rooftop equipment and nearby structures; and the interconnection path. Licensed engineers and the utility make final determinations.
What changes the financial case?
Compare cash ownership, financing and a power purchase agreement (PPA), where a third party typically owns the system and sells output under contract. Federal investment tax credit (ITC) eligibility, depreciation and other incentives depend on current rules and project-specific facts; qualified advisers should verify them. Include operations and maintenance (O&M), insurance, replacement reserves and end-of-term obligations.
How is an underperforming system diagnosed?
Qualified technicians may review inverter and anti-islanding event logs, use infrared thermography for hotspots, I-V curve tracing for string performance, insulation-resistance testing for suspected ground faults, or electroluminescence imaging for hidden cell damage. Testing depends on the symptoms and safe access; these are not all routine tests.
Already have rooftop or carport solar?
For an aging or underperforming system, compare repair, partial repowering and broader modernization before replacing equipment. Evaluate SMA inverters and SolarEdge inverters alongside monitoring, module compatibility, roof or canopy condition, switchgear and future loads.
