Hybrid Energy Solutions for the Rail Industry

At SolGen, we’re transforming the rail industry with our cutting-edge off-grid power solutions, tailored for a range of railway maintenance projects.

Innovation lies at the heart of our approach, and we have developed the most advanced solar hybrid technology available anywhere on the market. We offer both static and mobile units for purchase or rental, ensuring high performance and maximum efficiency for all rail-based projects.

These units are engineered to alleviate the burdens of emissions, pollution, and the inefficiencies of producing power with no access to mains power.


Why Choose Our Hybrid Power Units?

90% Emission Reduction

Our generators are capable of operating on either diesel or HVO biofuel, offering flexibility in fuel choice. HVO biofuel enables net zero operation, resulting in a substantial decrease of up to 90% in CO2 emissions, as well as a reduction in Nox, Sox, and other harmful emissions commonly produced by railway networks.

Self-Contained Units

Our units, though fully self-contained, integrate solar, battery storage, and a Stage V HVO generator, making them easy to transport within or between sites.

Reduced Dependency on Diesel Generators

Traditional diesel generators consume excessive fuel, emitting harmful pollutants in the process. By adopting SolGen energy solutions, rail maintenance and development projects can optimise energy usage as needed, reducing environmental impact and operational costs.

Clean, Efficient Power for Railway Projects

The rail industry, and the transport sector in general, is increasingly embracing renewable energy solutions in a bid to reduce costs, emissions, and enhance efficiency.

Our pioneering systems seamlessly integrate solar power with efficient generators, offering a reliable, cost-effective, and consistent energy source for off-grid railway sites.

This technology effectively reduces fuel consumption and operational costs associated with generator maintenance. In fact, our clients report average savings of up to £700 per week, stats which are accessible and monitored through a bespoke reporting system.

“Our collaboration with Solgen on a highways project near Gloucester was a game-changer. We tested their original prototype solar hybrid generator to power a suite of four cabins, including welfare, toilet, drying room, and office cabins. Despite limited space and the less-than-ideal orientation of the solar array, facing north and under the shadow of trees, SolGen’s innovation resulted in significant fuel and cost savings.Despite the limited space and the less-than-ideal orientation of the SolGen’s solar array (pointing east and under the shadow of trees), the site team observed significant fuel and cost savings.The integration of SolGen’s telemetry and portal system, coupled with expert advice from the SolGen engineering team, enabled us to program the system’s smart controls effectively. This optimization not only minimized on-site power consumption but also ensured that all the site’s power needs were fully met.What stood out most was the impressive performance of the SolGen units. SmartWatch is thoroughly impressed with both the product’s capabilities and the commitment of the SolGen team. This experience has solidified our confidence in SolGen’s innovative solutions and commitment to excellence.”

Easy Installation

The rail network stretches far and wide, with many miles of tracks and train stations situated in very remote parts of the UK. Our systems are easy to transport and install in any remote location.

Smart Automation

Our automated system seamlessly manages power load between solar, battery, and a generator, reducing user intervention. The integrated generator will only start when battery levels drop or power demand exceeds inverter capacity, minimising generator usage and associated costs.

Net Zero Operation

Our generators can run on diesel or HVO biofuel interchangeably as preferred but choosing HVO
biofuel gives net zero operation and reduces significantly CO₂ by 90%, plus reducing particulate,
Nox, Sox and and other emissions when compared to conventional diesel.
