In every box of fresh fruit, in every litre of milk that makes it from farm to shelf, there’s a journey that starts long before the market opens. It’s a journey powered by people — farmers, drivers, logistics operators — and too often, by diesel. But today, that journey can take a new route: one illuminated by the power of the sun.
Welcome to the new era of solar-powered refrigerated transport — a solution that doesn’t just cool your goods, but also warms the hearts of those who care about the environment, energy efficiency, and economic survival in a competitive sector.
The Hidden Cost of Cold
For food distributors and transporters across Colombia and Latin America, keeping products cold in transit is not a luxury — it's a necessity. Thermo Kings and other refrigeration units are vital tools, but their fuel consumption is high, maintenance costs are constant, and emissions are inevitable.
Each hour of engine idling to power refrigeration racks up fuel bills and contributes to environmental degradation. In a country where diesel prices keep climbing and regulatory pressure on emissions is growing, this model is simply not sustainable.
Refrigeration that Rethinks Energy
Imagine a different fleet — like the one pictured above — where refrigerated trucks, vans, buses, and delivery vehicles silently charge under the sun as they work. With flexible solar modules integrated into their roofs and sides, these vehicles become self-sufficient, clean energy carriers.
This is no longer science fiction. Thanks to the latest in ultra-lightweight, high-efficiency flexible solar panels, Thermo King units can now operate partially or even fully on solar energy. The benefits ripple through the entire chain:
Fuel savings of 30% to 70% on refrigeration
Lower emissions and access to green financing programs
Quieter operations in urban centers and residential zones
Fewer maintenance issues due to less engine use
Extended range for hybrid or electric vehicle fleets
Compliance with evolving environmental and transport regulations
A Business Case Rooted in Reality
For fleet operators and business owners, this technology is not only about sustainability — it's about profitability.
In Colombia, thousands of small to mid-sized transporters operate on tight margins. By reducing diesel use, they unlock immediate savings. In rural areas, where energy infrastructure is limited and fuel delivery is costly, solar Thermo Kings can be a game-changer.
Supermarkets, exporters, and last-mile distributors are also recognizing the value of working with solar-capable fleets. It demonstrates environmental responsibility while ensuring uninterrupted cold chains — crucial in a country with varied climates and long travel routes.

Solar-Powered Logistics: A Colombian Advantage
Colombia has over 1.3 million registered cargo vehicles. If even 10% of these adopted solar refrigeration systems, the country could avoid thousands of tons of CO₂ annually, reduce dependency on imported fuels, and empower a new generation of eco-logistics providers.
This is not a dream — it’s already happening. And you can be part of it.
Whether you're a fleet manager, a food producer, or a logistics entrepreneur, Welflare invites you to explore how solar can transform your operation — for your business, for your country, and for future generations.
Reach out to us today and let's bring solar power to your Thermo King fleet.
The road to sustainability is open — and the sun is already shining on it.
