The world’s first 100% solar-powered 24-hour off-grid mobile cabin has been successfully piloted for the construction workforce by global leader Consolidated Contractors Company.

Partnering with German energy storage experts Tesvolt and working in accordance with the agenda set by the UN’s General Assembly, CCC developed the world-first off-grid 100% solar-powered 24-hour office and accommodation cabin – which meets day and night energy demands, maintaining a room temperature of 25oC, considering a peak outside ambient temperature of 50oC (assuming a minimum of 6 hours direct sunlight per day).

The cabin caters for office use in daytime hours, and accommodation for workers overnight - PV panels supply power during daytime and the excess generated power is fed into the battery storage to support the demand during the evening hours. The system can be constantly monitored, analysed and adjusted anytime online – from anywhere in the world.

Consolidated Contractors Company Manager M.I.S. & Business Processes Re-engineering, Aref Boualwan, said ensuring efficient and reliable methods of cooling for workers on-site had always been a priority for CCC.

“The majority of our personnel are positioned on sites across the MENA region, where average temperatures are always high. As a company we have consistently made use of the high solar energy potential in the region – and for this project, we wanted to focus on off-grid renewable energy systems for our workers day and night, which are the most appropriate due to geographical constraints and costs for grid extension,” Mr Boualwan said.

“A group of engineers with diversified technical backgrounds and subject matter experts, based in different locations around the world, developed the 100% solar-powered off-grid mobile cabin. The energy system was designed, engineered, constructed, tested, and commissioned following the latest codes and IEC Standards. The prototype utilised solar photovoltaic modules, inverters and lithium ion batteries to provide a consistent energy ecosystem that combines efficient LED lights and appliances.

“This energy self-sufficient mobile cabin is an innovative off-grid solution and just the first step of our strategy on renewable energy and energy storage systems for the industry.

“Considering the remote project areas we work within, this successful pilot is strategic and of the utmost importance – not only for the construction industry, but for society as a whole.

“CCC and Tesvolt are proud of this collaboration, and believe that this success story represents a great foundation for the future strategic partnership of both companies.

“With declining costs and increasing performance of solar photovoltaics (PV) as well as declining costs and technological improvements in battery storage and control systems, off-grid renewable energy systems could become an important growth market for the future deployment of renewables.

“With the installed system, it is possible to view key data, analyse measured values, and visualise/compare yields conveniently and concisely online. Thus, minor deviations can be detected and resolved quickly – we can monitor the system from anywhere in the world,“ Mr Boualwan said.

"CCC consequently pursues the idea of using 100 per cent of the sun's energy", says Daniel Hannemann, Commercial Director of Tesvolt. "We are very pleased to contribute our resilient and long-lasting battery storage systems, as they are a crucial part of this project."

German manufacturer Tesvolt specialises in high-performance lithium-ion battery storage systems for commercial and industry purposes. Tesvolt uses battery cells from Samsung SDI from the automotive industry that are particularly safe and reliable. The battery storage systems have a service life of 30 years, are particularly low-maintenance and can achieve high performance even in an environment with high temperatures.
