Challenges for Floating application


No dedicated standard or rule for Floating PV application are available nor in development.

Technology?

PV module technology is well established but installed over a body of water…

Planning and execution?

Environmental conditions, water level differential, waves, salt, wind?

Restricted area for ship course? Aquatic plants situation, Bird droppings etc.

Financing?

Lack of commercial track record…

Development of criteria


Process to establish a new standard

1. Review of current situation as basis

2. Definition of scope and limitations

3. Research on similar/comparable applications and applicable standards

4. Determination of critical path

Transfer existing knowledge and new criteria into new rule.

Development of criteria as an example1. Review of current situation as basis

Development of criteria as an example2. Definition of scope and limitations


Floating Photovoltaic

On sweet water, no offshore application

Mechanical stability

Electrical safety including grounding

Grid connection

Stability/Suitability of components

Thoughts on yield are not in the focus

Development of criteria as an example3. Research on similar/comparable applications and applicable standards

VDE did a positive review of evaluation method and technical concept of a floating photovoltaic system focusing on following aspects:

• Overall concept

• Evaluation method of ambient conditions

• Concept of floating body

• Statistical assumptions and calculations

• Material and equipment selection

• Moorage and fixation

• Overall electrical design

• Electrical safety concept
