Phoenix, AZ Commercial Solar Installation – Construction Company

This commercial property spans about 115,000 square feet. Before solar, utility costs averaged $6,800 per month—an expense that fluctuated with seasonal demand. The Solar Topps engineering team designed a high-capacity system using 918 PV panels, configured to provide a roughly 110% offset and estimated lifecycle savings of $3,569,856 or more. Installation planning accounted for structural loads, roof penetrations, and operational considerations unique to the business, ensuring minimal disruption during construction while maximizing output for decades to come.

A high-capacity 918-module rooftop system designed for industrial power demand. By carefully selecting module orientation, tilt and spacing, the team ensured optimal production during peak sunlight hours. Inverter placement and electrical distribution were planned to minimize voltage drop and comply with the National Electrical Code. The result is a system that blends into the property while delivering clean power year-round.

Phoenix lies within the sun-soaked Phoenix metropolitan area, enjoying over 330 days of sunshine each year and ranking among the sunniest regions in the United States. Studies place Phoenix and Tucson at the top of national charts, with an estimated 85% of possible sunshine on average. This extraordinary solar resource means that properly designed PV systems here achieve high capacity factors, making investments in rooftop solar particularly attractive.

Beyond climate, regulatory frameworks support solar adoption. Arizona’s major utilities—Arizona Public Service (APS) and Salt River Project (SRP)—offer net-billing or export credit arrangements, allowing customers to earn credits when excess energy is returned to the grid. Residents and businesses in Phoenix will typically fall under one of these service territories. Choosing a rate plan that matches consumption patterns (for example, time-of-use or demand-based structures) is key to maximizing value.

Permitting has also become more streamlined. Many jurisdictions in the Valley participate in the SolarAPP+ program for qualifying residential projects, expediting code compliance and reducing plan review times. For commercial projects, local building departments provide clear checklists covering structural considerations, electrical one-lines, and equipment specifications. Combined with abundant sunshine and supportive policies, these factors explain why solar adoption across Maricopa County has accelerated in recent years.

This system is modeled to offset around 110% of annual energy needs, dramatically reducing dependence on utility-supplied electricity and providing long-term cost stability. By locking in a portion of their energy production for decades, the company team can hedge against future rate increases and take advantage of net-billing credits. The estimated 25-year savings of $3,569,856 are based on conservative assumptions about inflation and system degradation.

Operationally, the solar array performs best during daylight hours—coinciding with peak loads driven by air conditioning and daytime occupancy. Smart meter data and system monitoring allow for further optimization, such as shifting high-energy tasks to periods when solar production is strongest. For businesses, the benefits extend beyond electric bill savings: on-site generation helps mitigate demand charges, contributes to sustainability goals, and can enhance property value.
