Colombian cleantech startup Unergy has secured fresh backing to accelerate the roll-out of distributed solar energy across Latin America. The company closed a $4 million pre-Series A equity round alongside an $80 million co-investment commitment dedicated to building mini solar farms in Colombia. Combined with a previous infrastructure alliance with Solenium, the new deal lifts total capital committed to Unergy’s platform to around $120 million.
Pre-Series A round and infrastructure commitment
The latest round was led by a European fund specialized in climate infrastructure, representing its first investment in a Latin American startup. Of the $80 million infrastructure commitment, approximately $40 million is already being deployed to finance new solar assets in different regions of Colombia. Unergy describes the transaction as a milestone for the country’s distributed generation portfolio and a catalyst for scaling its mini solar farm model.
Scaling the mini solar farm model in Colombia
Unergy focuses on mini solar farms, typically around 1 MW in capacity, that inject decentralized power into local grids rather than relying solely on large centralized plants. Co-founder and CEO Eduardo Ospina noted that Colombia currently has 72 such projects and argued that the new capital will help multiply that number over the coming years. By prioritizing smaller plants closer to consumption points, the company aims to reduce grid losses, diversify generation, and strengthen local energy resilience.
Regional momentum in distributed solar energy
The surge in capital comes as Colombia rapidly increases its number of mini solar farms, moving from four projects in 2023 to 31 in 2024 and 72 in 2025. Even with this acceleration, the country is still considered an early-stage market compared with regional peers such as Chile and Brazil, where distributed solar has scaled to several gigawatts. Unergy estimates, using data from network operators and the Mining and Energy Planning Unit, that Colombia could add around 2.5 GW in mini solar capacity in the coming years.
Addressing financing gaps and regulatory hurdles
Despite the momentum, renewable energy developers in Colombia continue to face structural financing and permitting challenges. Industry association SER Colombia has highlighted that a high share of projects under development still lack financial closure and can face approval timelines stretching over several years. In this context, Unergy argues that the entry of a specialized international climate infrastructure investor provides a signal of confidence and can help attract additional capital into clean energy and regional development.
Strategic partners and agrovoltaic innovation
Beyond funding, Unergy emphasizes the strategic nature of its new partner, which shares the company’s long-term vision for distributed solar infrastructure. The startup reports a pipeline of more than 100 MWp in projects and plans to combine the new resources with its existing Solenium alliance to accelerate deployment. Unergy is also promoting agrovoltaic projects that integrate solar generation with agricultural or livestock activities, aiming to optimize land use, support rural employment, and align climate investment with local economic development.
With its pre-Series A round and substantial infrastructure commitment, Unergy is positioning itself as a leading player in Colombia’s nascent mini solar farm segment. The company’s ambition is to surpass 1 GW of installed capacity across Latin America within five years, contributing to emissions reduction through decentralized clean energy. If it delivers on this pipeline in a challenging regulatory and financing environment, Unergy could become a reference case for how distributed solar and climate infrastructure capital can converge in emerging markets.
