The discussion about distributed generation in Latin America has entered a new phase. During the ADLATAM 2026, held in Buenos Aires on the days May 20 and 21, 2026 It has become clear that the regional debate is no longer just about connecting new solar systems to the grid. The central theme now is different: how to transform millions of consumers into active participants in an increasingly decentralized, digital, and bidirectional electricity system.
That was precisely the provocation of the panel that I had the opportunity to moderate. “From connection to management: strategies for sustainable integration of distributed generation”, held on May 21st, focusing on the sustainable integration of distributed generation, the impacts on distribution networks, and the new role of consumer-producers.
The event's agenda itself accurately summarized the challenge: the expansion of distributed solar generation is reversing power flows and requires grids capable of operating safely, with financial stability and adequate market signals.
It is in this context that solar energy subscriptions should be analyzed. More than just a commercial product, they represent one of the most relevant ways to democratize access to renewable energy in Latin America.
The model allows consumers without their own roof, without capital for initial investment, or without the appetite to undertake the technical management of a photovoltaic system to access the benefits of solar generation through credits, quotas, shared generation, or remote self-consumption. In Brazil, this market already has scale. In Latin America, it is still an asymmetrical promise.
What we call a solar signature.
The term "solar signature" does not appear in a standardized form in the official regulatory frameworks of most Latin American countries. In Brazil, it is a commercial term applied mainly to models classified under... Electric Energy Compensation System, established by Law No. 14.300/2022, which created the legal framework for micro and mini-distributed generation.
In practice, solar energy subscriptions typically rely on three Brazilian regulatory frameworks: Remote self-consumption, shared generation and, on a smaller scale, condominiums or developments with multiple consumer units.Therefore, to accurately measure the market, it is necessary to use these modalities as a technical approximation, and not treat "solar subscription" as an official statistical category.
This distinction is important. The market should not be measured solely by the number of companies offering digital plans to discount electricity bills, but by the number of consumer units receiving energy credits from remote or shared power plants.
The size of the Brazilian market
Brazil is currently the leading Latin American market for distributed solar generation and the most developed environment for solar subscriptions. According to EPE, with consolidated data from 2025, Brazilian micro and mini-distributed generation has reached... 45 GW of installed capacity, answered 7,2 million consumers and generated approximately 54.483GWh in the year.
When observing the area closest to the solar signature, the data from ANEEL Data indicates that remote self-consumption involves approximately 2,76 million consumer units receiving credits, with approximately 11,37 GW of installed capacity. Shared generation totals approximately 1,55 million consumer units, with approximately 2,74 GW.
Combined, these two modalities represent more than 4,31 million consumer units and approximately 14,1 GW of power — a dimension that positions solar energy subscriptions as one of the largest retail energy markets in the country.
In relative terms, this means that models associated with solar signatures already represent something close to 60% of consumers served by Brazilian micro and mini-distributed generationconsidering the base of 7,2 million consumers served by MMGD in 2025. In terms of power, the segment of subscription, remote self-consumption, and shared generation corresponds to approximately 31% of the total installed capacity of Brazilian MMGD.
These numbers show a structural shift. Distributed generation is no longer just the market for rooftop owners. The new frontier lies with consumers who want access to solar energy without buying a photovoltaic system.
Brazil's participation in Latin America
Latin America currently lacks a standardized regional official framework for "solar subscription." Each country classifies its models differently: distributed generation for self-consumption, surplus compensation, energy communities, collective generation, net billing, self-production, or shared generation.
Nevertheless, the available data allows for a clear conclusion: Brazil has the largest regional scale for distributed solar generation and, consequently, leads the Latin American solar subscription market..
The International Energy Agency notes that, in Latin America, higher final tariffs have driven the expansion of distributed solar. The same report highlights, however, that the region is beginning to face grid challenges, including risks of generation restrictions in markets such as Brazil and Chile.
The Brazilian difference lies in the scale. While many Latin American countries are still structuring their frameworks for self-consumption, energy communities, or surplus compensation, Brazil has already transformed distributed generation into a mass market, with millions of consumer units, thousands of municipalities served, large digital platforms, and growing participation from institutional investors.
Chile, Colombia, Mexico, and Argentina: promising markets, but at different stages.
O Chile It has a mature technical environment for renewables and consolidated regulation of distributed generation for self-consumption. The Superintendency of Electricity and Fuels defines distributed generation for self-consumption, known as net billing, such as the right of users to sell surplus products directly to the distributor at a regulated price.
The Chilean model, however, is still more geared towards individual self-consumption and surplus compensation than towards mass-market solar subscription platforms. The opportunity exists, but it will depend on the evolution of collective models, energy storage, and active grid management.
Na ColombiaThe most relevant agenda is in energy communities. CREG approved regulations for 2025 to integrate energy communities into the electrical system, enabling new self-generation and pooled generation schemes. The Colombian Ministry of Mines and Energy stated that the measure could benefit more than... 500 families, opening up space for collective models of access to renewable energy.
A Argentina Brazil has Law No. 27.424, aimed at distributed renewable generation integrated into the grid, with official reports monitoring its implementation. The country has excellent solar resources, especially in the northwest, but still faces macroeconomic, regulatory, and financing barriers that hinder the widespread adoption of subscription models.
O MexicoWhile solar energy has potential scale, a relevant consumer base, and strong solar resources, the advancement of models similar to solar subscriptions depends on regulatory predictability, clarity on commercialization, and greater openness to private energy retail structures.
The most important fact: solar subscriptions are a consumer market, not just a generation market.
Solar subscriptions need to be analyzed less as an extension of the traditional photovoltaic market and more as an energy consumption market.
In Brazil, the signal is already evident. If more than 4 million consumer units can be associated with remote or shared distributed generation (DG) models, the product ceases to be a niche product. It begins to compete for monthly budget, consumer trust, service quality, credit, retention, default rates, churn, and reputation.
The next phase will be less romantic and more sophisticated. The solar signature will require:
- Management needs credit;
- efficient allocation of energy;
- delinquency control;
- More transparent contracts;
- Integration with distributors;
- intensive use of data;
- and greater governance over trade promises.
Consumers don't buy "solar energy" in an abstract way. They buy cost reduction, predictability, simplicity, and reliability.
The challenge for distributors
The ADLATAM 2026 plan sent a clear message: distributed generation will only be sustainable if the region stops treating it as a peripheral phenomenon and starts integrating it into the actual operation of the grids.
The event's agenda focused on themes such as digitalization, smart metering, automation, resilience, service quality, and the evolution of distributors towards a role closer to that of... active operators of the distribution system.
This is crucial for solar subscriptions. The greater the number of consumers connected to remote power plants, the greater the need for operational predictability, low-voltage visibility, flow reversal management, locational signals, and coordination between agents. Solar subscriptions don't grow in a vacuum. They grow over the distribution network.
Projections: the market still has significant room for growth.
EPE projects, in the reference scenario of the PDE 2035, that Brazilian micro and mini-distributed generation could reach 78,1 GW by 2035, with approximately 9,5 million consumers and a contribution of 12,1 GW of average electricity generation. In alternative scenarios, the installed capacity of MMGD could vary between 61,4 GW and 97,8 GW.
The most strategic piece of data is that distributed generation already represents about 5,6% of the electricity generated in Brazil and approximately 13% of the national captive consumption, according to MME and EPE.
This means that solar subscriptions, while often sold as a product to save on electricity bills, are part of a much larger transformation: the redistribution of economic power in the electricity sector, with consumers, digital platforms, investors, and distributors vying for the final interface with the customer.
Conclusion
Latin America has sunshine, consumers pressured by tariffs, a need to expand access to renewable energy, and grids that will need to modernize rapidly. But only a few countries have managed to transform these conditions into a market.
Brazil took the lead. It has scale, regulation, companies, platforms, investors, consumers, and an operational track record. Therefore, when talking about solar subscriptions in Latin America, Brazil is not just a relevant case. It is the most advanced laboratory in the region.
The next step will be to separate growth from maturity. Growth meant connecting plants and acquiring customers. Maturity will mean delivering cost savings with safety, governance, contractual transparency, and efficient integration into the grids.
Solar energy will be one of the most important gateways for the Latin American population to energy innovation. But its success will depend less on commercial rhetoric and more on the ability to transform distributed generation into distributed management, precisely the central point that emerged from the debates at ADELATAM 2026 in Buenos Aires.
