We want to make green energy and solar cells an integral part of the transport sector.
We provide intelligent solar solutions for the transport industry that reduce CO₂ and fuel consumption.
The people behind SunPower2u are among the pioneers of CIGS solar cells for buses and are registered inventors on a number of the basic patents on which the technology is based.
We have used this background to continuously develop the systems. Today, we offer solutions for both standard installations and more demanding setups - always adapted to the actual operating conditions in the market.
Experience is broad and current solutions are characterised by low weight, high efficiency and a payback time that speaks for itself - combined with stable operation, lower consumption and a greener footprint.
A bus spends thousands of hours on the road every year. All that time, sunlight hits the roof without being utilised. With CIGS solar cells, that surface becomes an active energy source.
Lower operating costs - without changes to the timetable
Install CIGS solar panels on your bus fleet for less than £ xxx per month per vehicle and achieve fuel savings of at least 5 % per year.
For route operators with high daily mileage, this means measurable savings from day one. The payback time for a scheduled bus is typically around 2 years - after that the savings are pure profit.

CIGS technology ensures continuous battery charging, even while driving and during periods of partial cloud cover. With solar panels on the roof, you avoid unnecessary idling at the terminus or depot - and extend the life of the battery and generator.
The result is continuous production of green power for everything that uses electricity: ventilation, air conditioning, lighting, passenger screens, USB charging and electronic equipment.
The panels are lightweight and flexible and adapt to the roof surface of the bus without affecting aerodynamics or the overall weight of the vehicle to a practical extent.
CIGS (copper, indium, gallium and selenide) solar cells differ from traditional rigid solar panels in three ways that are directly relevant to bus operations:
Low weight. A bus is already a heavy vehicle. CIGS panels add minimal weight compared to conventional glass-based panels and do not affect passenger capacity, load capacity or overall vehicle economy. This makes them practical without compromise.
Flexibility. Bus roofs are rarely completely flat - they often have slight curves, brackets and penetrations that rigid panels cannot bypass. CIGS technology is installed directly on curved and uneven surfaces, utilising the entire roof area. Installation does not require any remodelling of the roof structure.
Nordic light efficiency. CIGS solar cells perform well in diffuse light and low light intensity - exactly the conditions that characterise Danish and northern European weather for much of the year. This means stable power production even on days when the sun is not clearly visible.
Together, these three characteristics make CIGS solar cells the most obvious choice for bus operators who want a solution that works in practice. Light enough to be unnoticeable, flexible enough to fit, and efficient enough to deliver even on a cloudy day.

Typically around 2 years with average driving patterns and normal power load on board.
The answer is yes. The panels are customised to the specific vehicle - bus, coach or city bus - and are mounted directly on the roof surface without major structural interventions.
CIGS solar cells are more efficient than traditional panels in diffused light. They still provide power during cloudy weather, and in limited sunlight they supplement the vehicle's existing electrical system.
