To highlight how smart hot water management can become a key strategy for reducing operating costs, increasing energy efficiency and advancing the decarbonization of the commercial and industrial sectors, Intersolar Mexico hosted the webinar “Solar Hot Water: From Energy Consumption to Smart Savings.” The specialized session is part of the content program leading up to Intersolar Mexico 2026, Mexico’s most important gathering for the solar and energy storage industry.
Recognized as the country’s premier international exhibition and conference focused on photovoltaics, solar thermal energy and energy storage systems, the seventh edition of Intersolar Mexico will take place September 1–3, 2026, at Centro Banamex in Mexico City.
The session featured David Contreras, representative of the Mexican Federation of Mechanical, Electrical, Electronics and Related Fields Engineers (FECIME), who explained that while the energy transition tends to focus on electricity generation, a significant share of energy consumption continues to be associated with hot water production , an area that frequently goes unnoticed.
“Thermal energy is present in virtually every facility, yet it remains invisible to decision-makers. While electricity consumption is typically monitored through utility bills and metering systems, thermal energy consumption remains hidden behind the everyday use of gas, making it more difficult to identify opportunities for savings and efficiency,” Contreras said.
The expert emphasized that solar thermal energy is no longer an emerging technology but has become a mature solution that is widely adopted internationally. He explained that by the end of 2023, approximately 560 GWth of solar thermal capacity had been installed worldwide, equivalent to nearly 800 million square meters of solar collectors in operation, figures that demonstrate the technology’s maturity and reliability.
The webinar highlighted that some of the greatest opportunities for integrating solar thermal systems can be found in processes with consistent hot water demand, including hotels, laundries, commercial kitchens, hospitals, sports clubs and a wide range of manufacturing processes.
Contreras also emphasized that a successful project involves more than simply installing solar collectors. It requires a comprehensive understanding of the thermal process to identify where hot water is needed, optimize its distribution and improve the efficiency of the entire system.
In the hotel sector, he added, ensuring a continuous supply of hot water is one of the main operational challenges and represents a significant share of energy costs. In this context, hybrid systems combining solar thermal energy with conventional technologies can ensure continuity of service, reduce fuel consumption and lower associated emissions without compromising operations.
Through these initiatives, Intersolar Mexico continues to strengthen knowledge exchange among experts, companies and decision-makers, promoting solutions that help accelerate the energy transition through more efficient, sustainable and economically competitive technologies.
The event will bring together manufacturers, distributors, developers, EPCs, integrators, installers, consultants and specialized suppliers from the solar and energy storage industries, as well as energy users seeking solutions to reduce energy costs, increase operational resilience, accelerate their decarbonization goals and strengthen business competitiveness. Intersolar Mexico provides a unique opportunity to explore and evaluate the solutions available on the market and gain insights from industry experts.
This year’s edition will also feature a free conference program at the Innovation Forum , where exhibiting companies will share success stories, technology launches and innovative applications for different industries. The International Conference will bring together national and international experts to analyze the trends, challenges and opportunities shaping the development of the solar industry. Conference passes are available online.
Intersolar Mexico is supported by some of the most influential organizations in the energy sector. Its Premium Partners include the Asociación Nacional de Energía Solar (ANES), Asociación Mexicana de Energía Solar (ASOLMEX), Bundesverband Solarwirtschaft (BSW) and Heat Changers. In addition, Intersolar Mexico collaborates with a network of more than 20 national and international organizations, including AMAEM, AMIF, FECIME, MERM, RAME, Global Solar Council, SolarPower Europe, GIZ and CAMEXA.
Intersolar Mexico will be held concurrently with Aquatech Mexico, creating a platform focused on two of the major challenges for sustainable development: the energy transition and efficient water management. Together, the events are expected to welcome more than 10,000 professionals and over 300 national and international exhibiting companies.
