Hybrid Energy Solutions for the Construction Industry

At SolGen, we’re revolutionising the way the construction industry operates with our technologically advanced range of off-grid power solutions.

Our units are designed to ease the pressures of pollution, emissions and inefficiencies on construction projects with cost-effective and sustainable power.

In doing so, we have developed the most advanced solar hybrid technology available anywhere on the market. We offer both static and mobile solutions to buy and rent for the construction industry, for high performance and maximum efficiency.


Why Choose Our Power Units?

90% Reduction in Emissions

Our generators can run on either diesel or HVO biofuel on an interchangeable basis as required. HVO biofuel however, offers net zero operation, which therefore significantly reduces CO2 emissions by up to 90%.

Single Self-Contained Unit

Although our units are completely self-contained, they combine solar, battery storage and a Stage V HVO generator, which is easy to transport around the site or between sites.

Less Reliance on Diesel Generators

Traditional diesel generators consume a considerable amount of fuel and produce a range of emissions – which are both harmful to the environment and for the people working on the site, and are often left running 24 hours a day.

Sustainable Power for Construction Sites

The need to drive construction to a more sustainable plane is absolutely crucial, and the industry is now beginning to embrace renewable energy solutions to save costs, reduce emissions and increase efficiency.

Our innovative systems seamlessly integrate solar power with efficient generators to offer a reliable, cost-effective and consistent energy source for off-grid construction sites.

This technology is capable of lowering your fuel consumption and the operational costs associated with generator servicing and maintenance. It’s because of this that our customers are reporting an average saving of up to £700 a week, which they can access and monitor at any time through a customised 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.”

Generator theft on construction sites is an increasing issue due to the lack of traceability. Our mobile generator units lower right to the ground to hide the wheels. The towing connections are covered by a lockable flap and each unit features high security access doors.

Renewable & Sustainable

The energy provided by the units predominantly comes from solar panels or the stored energy in the lithium-ion batteries.

Auto-Start Technology

The generator provided within the unit will auto-start if the battery levels drop or the power demand exceeds the capacity within the inverter. This vastly reduces the time the generator is being used, reducing costs for considerable savings.

Intelligent Automation

Once the automated system is ready to go, it will automatically shift the power load between solar, battery and generator, vastly reducing user intervention.

Sophisticated Telemetry & Smart Controls

Our pioneering telemetry and smart control allow users to track and monitor construction site power usage. You can then input site-specific variables automatically and remotely to eliminate unnecessary energy consumption and optimise the renewables produced by the unit.

Full Accountability

You can take a deep dive into carbon production, power consumption, generator usage, solar power, fuel use and battery status within our bespoke reporting software. You can also create accurate and transparent reports to help you monitor costs and carbon emissions.

Who Are SolGen

SolGen was founded by the team behind Boss Cabins’, who created the revolutionary and pioneering generator free solar welfare range GenFree.

This experience gives us all the knowledge we need to meet the energy needs of construction sites of all sizes, with advanced solar hybrid technology superior to anything currently available on the market.

All of our units are available to buy or hire, and both designed and manufactured in the UK in Bourne, Lincolnshire.

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.


“It depends” This question needs discussion between yourselves and the Technical Sales team at Solgen, you will need to know what you are powering, what location it is being used in and whether you have any restrictions on running the generator at night.

On the static unit they are all raised and lowered with electro hydraulics via a pendant.
On the mobile unit you manually slide out the extensions and then raise them with the hydraulic power pack.

All the units use LIFEPO4 lithium batteries.

During normal operation the unit is silent. When the generator is recharging the batteries there will be a maximum level of 82dB 1m from the unit.

Yes, any dirt left on the panels will affect their ability to absorb power from the sun, they can easily be hosed down which should remove most dirt, if not use a soft brush.

This is lowered to the ground with hydraulics and the wheels are then inside the unit and not visible. There is also a lockable flap over the front bulkhead preventing anyone from connecting to the lights.

Yes, if you want to gain the maximum solar you must always face the solar panels South. Facing any other direction will not gain as much solar power.

Yes, as long as you have fuel or enough solar power for what you consume then it will continue to run. You can also set quiet hours so the generator will not start at night if you have the unit deployed in a residential area.

You can set timers and current limits on all of the output sockets, these are easily set either from the display screen or the online portal.

The user can be informed via alarms on the screen on the unit and also email alerts for a variety of scenarios, the main ones will be low fuel, overloading the unit and fuel theft.

Yes, this is shown very accurately on a Google map. This is visible all the time, even when it is being transported.

Solgen can provide you with reports to show how much you have saved within any given time frame, this will generally be compared to running a standard diesel generator.

The mobile unit running gear will need to be serviced every 6/12 months as this is road going. The only other maintenance is the generator servicing, but as this is running a lot less than your normal generator would then the time between services will be considerably longer.

Yes, this can be fitted but it would not have the same functionality as the timers in the single phase systems.

Yes we sell and hire these units and can also arrange delivery to sit and the initial setup/

Yes they do, this is all carried out as part of the site set up by Solgen engineers.

Solgen are totally designed and manufactured in the UK.

Yes we can paint them in any colours you like and provide them fully decalled with your logos.

Yes, they can at a maximum rate of 32A. So it would take around 8 hours to fully charge most cars.
