The project makes use of the standardized in container shipping both. ISO containers simplify transport due to standardized size and standardized corner casting and twist lock allow for simple mounting configurations. This project aums at development of a PV system for standardized mounting on containers requiring:
AP1 Development a standardized PV system to fit to ISO-Container mountings allows for fast and simple
PV system installation for container ships
AP2 Electrical interconnection and connection to board electronics
AP3 Logistics for storing, loading and unloading these systems must be developed
AP1 Development of standardized PV system
ISO container sizes are standardized
* 20‘: L=6.058m, B=2.438m
* 40‘: L=12.192m, B=2.438m
Possible module configurations
* 20‘: 3x2x 60-cell modules, 1,98 kWp @ 330Wp/module (current best in class standard)
* 40‘: 7x2x 60-cell modules, 4,62 kWp @ 330Wp/module (current best in class standard)
PV mounting on containers use a standard steel frame as
used for the container itself
* 2 racks of 3 or 7 modules can be used for 20‘ and 40‘
* The racks can be horizontal for storage and tilted by 10°
when in operation
* Standardized electrical connections – optimized string or
module level power optimizer per container
Integration of battery storage must be explored
AP2 Electrical interconnection
The PV-Systems should come with PV modules, power optimizers or MPP trackers and inverters to allowing simple wiring on board the ship with standard AC power wiring.
The research project explores opportunities for electrical system integration. It must be identified how to interconnect the systems on each container and how to connect the system to the ships electrical circuits.
Very importantly logistics solutions must be investigated on how to store, connect and load the PV systmes to the ships answering following questions:
How and where can PV-Systems developed in 1. be stored on shore?
How and when are the PV-Systems mounted to the top containers on a ship? On shore or on the ship?
