THE POWER OF SOLAR

Sustainable and profitable

At Green Energy, we focus on practical sustainability solutions that bring immediate benefits for our customers: simple measures that simultaneously drive efficient and profitable operations. For us, sustainability is not about choosing between environmental responsibility and commercial reality. It is about delivering solutions that support both, every day.

SCALABLE BENEFITS

Delivering impact today

The transition to low-carbon transport needs to involve multiple technologies. Electrification, alternative fuels and new vehicle platforms all play an important role, but their availability, cost and readiness vary widely across fleets and regions. Solar is widely accessible now.

Solar is a simple upgrade that helps operators reduce fuel use and emissions today. Incremental improvements, when implemented at scale, deliver real impact and help fleets move forward towards their decarbonisation goals.

FLEXIBLE SOLUTION

Part of the alternative fuel mix

Vehicle-mounted solar complements other decarbonisation approaches. It works alongside diesel, HVO, biogas and electric vehicles, supporting mixed fleets and transitional strategies. That means you can install solar to diesel trucks now and also to vehicles running on alternative fuels for extra operational efficiencies. The simplicity of our solar systems means that it can be easily adopted by partner and subcontractor fleets, contributing to Scope 3 progress.

FAQs

Frequently asked questions

Impact is measured using operational vehicle data, comparing the same vehicle with and without solar contribution over time. This links reduced fuel consumption directly to lower CO₂ emissions.
CO₂ reductions vary by vehicle type, duty cycle, climate and electrical load. On trucks, fleets typically see 1–3 t CO₂ per vehicle per year. On buses, annual reductions are typically 4–6 t CO₂ per vehicle.
On vehicles running on diesel, HVO or biogas, solar generates onboard electricity and reduces alternator load, further lowering fuel consumption and emissions. On EVs, solar provides additional electrical power for auxiliary systems, reducing draw on the main battery and improving reliability.
Our solar panels have an environmental footprint of 10–26 g CO₂e per kWh of electricity produced. This is based on a third-party verified Environmental Product Declaration (EPD), supported by a full Life Cycle Assessment (LCA). The EPD covers panel models from the same manufacturer, using the same CIGS technology and production process as our transport systems. Their lifecycle emissions are therefore a reliable and representative indicator for our panels. For context, conventional crystalline silicon panels typically range between 13–60 g CO₂e per kWh.

Solar starts delivering measurable emissions reductions from day one.

It is easy to install, easy to scale, compatible with almost all vehicle types, and requires no operational change or ongoing maintenance.

Combined with a fast payback, this makes solar a practical sustainability measure that fits into all transition strategies.
