Moss Maritime – Floating solar park

A Leader In Maritime Technology

Moss Maritime – Floating solar park

Concept• Floating solar park for inshore and offshore location• Standardized modules: Efficient fabrication and low maintenance• Typical module size of 10x10 m that can carry solar cell units

Specific design depends on location and weather• Flexible connection between modules that allow some relative motion

Floater module

• Simple layout – few parts

• Prefabricated elements – already in the marked

• Easy access – between modules and to all solar panels

• Module based – Easily expandable number of units

1 wave length = at least 10 units

Offshore location• Swell waves with significant wave heights up to 3-4 m with long periods Period

10 sec wave length ~150 m.• Modules will be interconnected and follow the wave contour.• Modules will be sized to be optimal for the specific location and waves.• Modules will be moored to seabed with mooring lines.

• Solar cell panels on Fleet Modules (FM), interconnected, up to 1500 VDC,

flexible cabling close to the module Flexible Connections.

• Each Group Central Fleet Modules (GCFM) receive power from the Solar

Cell panels on its own fleet module, and in parallel from panel strings located

on surrounding Fleet modules.

• Each GCFM will contain an Inverter Module, converting DC to LV AC, typical

440V.

• The inverter modules to be interconnected at the Power Module for Shore

Connection, PMSC.

Energy produced by Solar cells:

E = A * r * H * PR

E= Energy (kWh)A=Total solar panel Area (m2)r= Solar panel yield or efficiency. (kWp/ Area, typical 0.17)

H= annual average solar radiation on tilted panel. Pending on location, in Africa it may be 2500 kWh/m2/a

PR= Performance Ratio of the installation, including all losses; inverters & transformers, DC&AC cables, temperature, shading, dust and other losses.(typically between 0.5 an d 0.9).

• Solar park example; 10x10 m Fleet Modules.

• 65% of park area with solar cells.

• 900 Fleet Modules; total solar cell area of about 58500 m2.

• Total floating Solar park rated power; 10 MW (peak).

• Energy supply to more than 4000 household.

SOLAR CELL DATA, example:

Area of one Solar cell panel: 1,627 m2

Total Area of Solar cells installed Park: 58 500 m2 Number of solar cell panels: 35 958,4

Peak power of one Solar Cell panel: 0,270 kWp Peak power of complete park: 9 709 kWp

Solar cell Efficiency (yield); Peak power in kW / area in m2, r= 0,17 pu (%/100)ENERGY CALCULATION:

Irradiated energi in Afrika (per year per m2), H = 2500 kWh/m2/a

Perforamnc Ratio, RP = 0,85

SUM Energy produced per year (E=A*r*H*PR): 21 133 125 kWh /a Equivalent cont. Power; 2 412 kW

A houshold with several persons may consume: 5 000 kWh/a Equivalent cont. Power; 0,57 kWThen, the solar park may supply: 4 227 households in africa

The voltage may be transformed up to MV (e.g. 11 kV), before electric power will be transmitted to shore via

submarine cables of length typical 1 - 10 km.
