First mobile photovoltaic power station in Romania
We recently delivered the first mobile photovoltaic power station in Romania: a renewable energy installation integrated into an expandable container that unfolds nearly 60 metres of solar panels directly on the ground. No building permit, no bureaucracy, no fixed infrastructure. Just transport, unload, unfold and produce energy.

The client's need
Electric equipment on site, but no grid
A client from Romania acquired 100% electric industrial equipment through European funding (Just Transition Programme). The funder's condition: every piece of equipment in the operational chain must be 100% electric, no diesel.
The problem: the electric equipment needs power on mobile worksites where the public grid is absent. A diesel generator would have nullified the principle behind the European funds. Fixed rooftop panels are not an option, because the team moves between locations.
The client needed a power source that moves with them, produces enough for industrial equipment, and meets the funder's zero-emission requirement.
How the photovoltaic power station solved it
Expandable container with 60 m of solar panels on the ground
The VOLTRAIL mobile photovoltaic power station solved all three problems at once: it is mobile (transported and deployed in 30 min), produces enough for industrial equipment (24 kW panels, 52 kWh storage) and is 100% renewable (zero emissions, eligibility maintained).
The 3×2.5 m container unfolds nearly 60 metres of solar panels directly on the ground. Two people, 30 minutes, no auxiliary equipment. 100% off-grid topology: no grid connection, no building permit, no authority approval.

Why this solution
Why the client chose the mobile photovoltaic power station
A
Complete grid independence
Industrial equipment runs continuously on any site. No longer depends on a three-phase outlet or the logistics of a diesel generator.
B
Compliance with European funding requirements
100% renewable energy with no direct emissions. The entire operational chain remains eligible for European funding lines that require exclusively 100% electric equipment.
C
Zero fuel operating cost
Compared to a diesel generator, the power station completely eliminates fuel spend. The saving over the project lifetime far exceeds the cost of the unit.
Contract value
€52,000 + VAT
Smallest model in the range, fully equipped: 24 kW panels, 52 kWh storage, 24 kW inverter, 3 outlet types, battery climate control, foldable panel system on wide rollers. Range goes up to 160 kW / 620 kWh.
Frequently asked questions · mobile photovoltaic power station
What is a mobile photovoltaic power station and how does it work?
It is a complete solar energy production installation (panels, batteries, inverter) integrated into a transportable container. It is crane-unloaded on site, panels are unfolded on the ground in 30 min and it produces energy immediately, with no grid connection.
What is the difference compared to a fixed solar park?
A fixed solar park requires a building permit, grid authority approval and permanent infrastructure. The mobile unit moves between locations: transport, unload, unfold, produce. No bureaucracy.
What power and storage capacity does it have?
24 kW solar panels, 52 kWh Li-Ion storage, 24 kW industrial inverter. 3×2.5 m container, weight ≈ 4 tonnes. The smallest model in the range.
How much does it cost?
€52,000 + VAT for the smallest model, fully equipped. The range goes up to a 12 m / 40' container with 160 kW panels and 620 kWh storage.
Is it eligible for European funds?
Yes. 100% renewable energy with no direct emissions. Compatible with JTP, NRRP, POIM/POIDD and other lines requiring 100% electric equipment.
Can it be customised?
Yes. We configure to your consumption and application, from 24 kW (smallest) up to 160 kW (largest).
Do the batteries withstand extreme temperatures?
The container has automatic internal air conditioning that keeps batteries at optimal temperature regardless of external conditions.
How is it transported and installed?
Standard road transport. Crane unload. Panel deployment on ground: ≈ 30 min, 2 operators, no additional equipment.
