Solar projects in Peru are moving towards an ever-increasing scale, and the size of the new developments is also beginning to change competition within the supply chain.
COES records initiatives that approach 400 MW , such as Illa Stage 1, of 396 MW , whose Operability Study obtained approval in March 2026. This scale coincides with the opportunities that Axial , a manufacturer of fixed structures and trackers, currently sees in the Peruvian market.
David Lôbo Sigismondi , Head of Sales LATAM for the company, noted that the company receives offers related to projects ranging from approximately 10 MW to 400 MW .
The increase in size puts greater pressure on design optimization and CAPEX, particularly for components that are replicated thousands of times within a plant.
One of the changes that Axial identifies is associated with the increase in power of photovoltaic modules.
“The increase in power has significantly reduced CAPEX. When we receive a quote for a project with higher power panels, the cost of the solution always decreases,” explained Lôbo Sigismondi during the Future Energy Summit (FES) Peru 2026 .
The Peruvian market already shows examples of this evolution. The second stage of Sunny , which added 105 MW , has 178,408 photovoltaic modules , a ratio equivalent to approximately 589 W per unit , according to data from Osinergmin.
For the same plant power, the use of higher capacity modules can reduce the total number of units required and, depending on the design, decrease certain structural and assembly requirements.
In developments of hundreds of MW, this optimization takes on a greater dimension and requires analyzing each project according to its own characteristics.

“It depends on each client and each project. On the geography, on issues of earthquakes, hurricanes, and the topography of the land,” the executive stated.
The choice between trackers and fixed structures is thus conditioned by variables that exceed the initial cost of the equipment and range from the characteristics of the terrain to the structural requirements of each site.
More scale, greater demands
The increasing size of projects is also raising the demands of developers and investors on suppliers.
“People are asking much more about the quality and traceability of materials, and at the end of the day this is proving to be a major differentiator,” said Lôbo Sigismondi.
According to Axial 's Head of Sales LATAM, the similarity between supply chains means that some of the competition is shifting towards the ability to provide engineering and reduce risks: "The supply chain is practically the same for all suppliers, so the competition is in the details, in engineering and in something that conveys more security to customers."
This scenario coincides with a solar portfolio that continues to grow in depth. In April, the Ministry of Energy and Mines reported 2,402 MW distributed across 13 projects with definitive concessions , representing approximately USD 1,805.9 million in investment .
Since then, new developments have also progressed, including Yuramayo, with 245 MW , which obtained its final concession in June.
Thus, while Peru consolidates projects increasingly closer to 400 MW , the discussion within the photovoltaic chain is beginning to focus on how much each design decision can contribute to optimizing structures, reducing CAPEX and limiting technical risks in larger-scale plants.
