Marlec introduces new sunpower panels
Renewable energy company Marlec, has introduced a new range of SunPower semi-flexible solar panels developed to deliver greater efficiency.
Available in four sizes from 50W to 170W, the panels have Maxeon ‘back contact’ solar cells and are said to be between 22% and 25% more efficient than standard silicon panels of the same area. Their flexible design means that onboard space can be maximised.
Interest has been high with the 170W version in particular proving attractive to electric boat owners, according to Teresa Auciello, Marlec’s MD. The panels help boat owners live environmentally on board by reducing fuel consumption, she explained.
The SunPower panels are shade resistant and can perform in extremes of temperature and even when light levels are low. They are suitable for use with both 12 and 24V batteries, with recharging is faster than standard solar panels.
The Maxeon Solar Cell is built on a copper foundation making it resistant to cracking and corrosion while the substrate is constructed of a lightweight polymer designed to withstand high UV exposure.
Scania to launch two new IMO Tier III-compliant engines at Seawork
Both power units – a six-cylinder, 13-litre DI13M and a V8 16-litre DI16M – feature Scania’s XPI injection system and use selective catalytic reduction (SCR) to meet the IMO Tier III standard. The injection system reduces emissions of nitrous oxides by more than 70% and the engines can also be run on hydrotreated vegetable oil.
“While the IMO Tier III standard is already
in force in the North American and US Caribbean Sea areas, all new ships constructed on or after 1 January 2021 destined to operate in European waters will also require IMO Tier III-compliant engines,” said David Bamber, general manager of Scania Engines.
Scania produces marine engines in the power range 162-846kW (220 - 1,150hp). The company’s products combine low revs with high torque and are suited to a wide range of propulsion and ancillary applications, including fishing vessels, ferries, fast patrol boats and survey ships.
