Design Automation Emerges as Key Edge in Global Solar Tendering Race

Competitive auctions now account for nearly 60 percent  of global utility-scale renewable deployment, according to the IEA. As procurement intensifies to meet growing energy demands, the ability to present multiple fully configured, constructible design scenarios in a single tender submission is emerging as a major competitive advantage for developers and EPC (Engineering, Procurement and Construction) contractors.

The tendering environment for utility-scale solar has changed. Bankability, execution capability and design specificity now determine which bids advance. For developers responding to bid windows, submitting a single design is a drawback. One design locks a project into one set of assumptions about inverter placements, cable routing, pitch and block capacity. The developer who submits multiple construction-level iterations gives the decision-maker a basis for comparison backed by real engineering data.

Paul Nel, CEO of 7SecondSolar, the solar engineering studio that developed AutoPV, said, “Producing a single detailed design for a utility-scale solar project can take an engineering team several months. That timeline makes multi-scenario submissions commercially impractical. The result is an industry norm where bids are built around a single configuration, optimised on experience, but never tested against alternatives.” 

AutoPV, the computational design software developed by 7SecondSolar, directly addresses this constraint, allowing developers to submit more competitive bids for utility-scale solar projects. Using algorithm-driven design automation, AutoPV generates multiple fully construction-ready iterations for the same site in minutes. Each iteration includes geo-referenced CAD drawings, validated electrical calculations, complete cable routing and a bill of quantities (BoQ) accurate to over 85 percent. These are not feasibility sketches. They are construction-level outputs that can be compared on cost, yield and technical performance.

Nel added, “In a competitive bid process, presenting one design is presenting one opinion. Presenting three constructible configurations, each with a detailed BoQ and validated energy yield, is presenting evidence. That is a fundamentally different conversation with a procurement committee.”

Global solar PV deployment is entering a period of adjustment. The market in 2026 is being shaped by tighter financing, policy shifts, tariff-driven component substitution and growing hybrid solar-BESS complexity. In the United States, developers are navigating a shrinking window to qualify projects for federal tax credits before they expire. In Europe, procurement committees are placing more weight on a bidder's ability to execute, not just their price. In the Middle East and Africa, government-led tender schedules are setting the pace for new capacity.

Across all three regions, more developers are competing for fewer allocations. When multiple bidders target the same project, the quality of the submitted design becomes a way to stand out. A bid that demonstrates how different equipment configurations affect project cost and energy output signals engineering depth.

Design automation software has typically been positioned as an internal efficiency tool. That framing misses the larger opportunity. When design iteration speed enables a developer to submit richer, more detailed, and more responsive bids, the value moves from the back office to the front line of business development, and it essentially becomes a tendering instrument.

For developers, EPCs, and IPPs competing in a market where margins are tightening, the ability to compare constructible design alternatives is no longer a luxury. It is the new baseline for a strong bid.
