"Dutch maritime solar innovator Wattlab has installed a 79-kilowatt-peak (kWp)
solar energy system onboard a diesel-electric multipurpose cargo vessel, which
will provide power to onboard systems and slash energy use by around 20 per
cent.

Wattlab, founded in 2017 to deliver innovative solar power solutions for the
shipping industry, says the PV array has been installed onboard the MV Vertom
Tula
, a 7,280-dwt diesel-electric multipurpose cargo vessel.

Wattlab installed a total of 44 of its Solar Flatracks, a solar system which
the company claims “turns unused deck space into clean, cost-saving energy,
without disrupting operations.”

It took less than a day to install the solar system, using container twist lock
fittings, and the system is expected to deliver a 20 per cent reduction to the
vessel’s on board load.

“For shipowners, time is money, so speed and ease of use are important,” said
Bo Salet, co-founder and CEO of Wattlab.

“Furthermore, we know that ‘space is money’ too. Hence, should the panels need
to be removed to make way for a special type of cargo, the crew can easily
stack and store them all on the footprint of one 20ft container.”"
