Jalisco’s rooftop and small-site solar market has moved into a new phase. State officials say the state has already crossed the 100,000 mark in distributed-generation contracts and could reach 120,000 before the end of 2026. The growth lowers power bills for some homes and businesses, but it also exposes a larger strain on Jalisco’s grid as factories, data centers, hotels, and commercial users add demand faster than public infrastructure can absorb it. The next test is whether the boom improves reliability or adds new pressure.
Jalisco’s Solar Boom Is Rewriting Home Power Plans
Jalisco has passed roughly 100,000 distributed generation contracts, keeping its lead in Mexico’s fastest-growing self-supply power market as the state pushes toward 120,000 contracts by the end of 2026.
The figure, cited by state energy secretary Manuel Herrera Vega, represents a 16 percent annual increase and about 17 percent of Mexico’s national total. It also puts Jalisco at 747 MW of installed distributed-generation capacity, mostly from residential and commercial systems.
That scale changes the conversation around rooftop solar and small-site generation. In Jalisco, self-generation is now part of a larger fight over power demand, grid capacity, and energy costs.
“We reached 99,949 contracts in 2025. We know that during 2026 we have already surpassed 100,000 contracts, but we want to reach 120,000,” Herrera said in remarks on the state target. He said that the goal would add about 20,000 contracts and bring installed capacity close to 900 MW.
Jalisco’s solar lead is now a grid question
Distributed generation refers to small-scale power produced near the place where it is consumed. In Mexico, it is dominated by solar panels on homes, businesses, warehouses, and other buildings.
The federal Plan de Desarrollo del Sector Eléctrico 2025-2039 says photovoltaic distributed generation reached more than 405,000 contracts and 4,423 MW nationally in 2024. Solar accounted for more than 99 percent of distributed-generation capacity that year.
The new Jalisco count builds on last year’s figure of more than 90,000 systems and 658.84 MW, when the state was already leading Mexico in solar self-consumption.
State officials are framing the growth as part of an economic strategy. Herrera said energy supply has become tied to investment decisions, especially as advanced manufacturing, artificial intelligence, and data-center projects add pressure to the grid.
The pressure is not abstract. Herrera said a state demand study indicates an additional 3,450 MW of electricity will be needed by 2030. He also said Jalisco already has a 35 percent energy deficit.
That is where the solar boom becomes more complicated. A solar panel system can reduce daytime demand from the grid and lower some bills. It does not remove the need for transmission upgrades, stronger local distribution networks, or larger supply planning.
The rule change opened a larger market
Recent federal rules allow distributed-generation projects below 0.7 MW to operate without a generation permit. The federal energy portal states that plants below that threshold are exempt generators, while plants at or above 0.7 MW require a valid generation permit.
That threshold gives more room to larger commercial roofs, hotels, schools, warehouses, and small industrial users. It is also one reason state officials expect faster growth this year.
CFE still controls the interconnection process for smaller systems. The federal energy portal lists the process for systems below 0.7 MW and states that the review can take 13 business days when no interconnection study is needed, or 18 business days when a study is required.
The same process lists 11 requirements. They include the interconnection request, site sketch, single-line diagram, technical data for the generating equipment, inverter certificate when applicable, and a recent CFE bill with no debt.
Those are review timelines, not a promise that a roof is ready, a supplier is qualified, or a project will be approved without changes. The paperwork remains part of the cost and risk of a solar installation.
Contracts do not mean energy independence
Jalisco’s number is a count of interconnection contracts, not a count of off-grid properties. Most distributed-generation users remain connected to CFE and still use grid power at night, during cloudy periods, or when consumption exceeds production.
The economics vary by property. Roof space, shade, wiring, tariff category, daytime consumption, and installer quality can affect the payback period. Larger systems can also face more technical questions from CFE before interconnection.
State officials say hotels, commerce, industry, agribusiness, and services have moved into distributed generation. That mix shows why the market is no longer driven only by household savings. It is also being used by businesses trying to control power costs and protect operations from supply constraints.
Herrera said the state is working with financing, leasing, insurance, training, and industry-linking tools around the sector. The claim is ambitious and still needs visible results beyond contract growth, especially if Jalisco’s demand curve rises as projected.
