Sun Rise OFPV is a floating solar specially designed for the open sea environment. It has been proven to withstand storm, and is expected to be placed in an area with wave heights of 7-14 meters.
Compared with floating solar installed inland and at harbor, in order to cope with the harsh environmental conditions and salt corrosion at sea, OFPV has extremely stricter requirements on the structure, service life and wave resistance.
In the past 15 years, the issue of offshore solar energy has gradually been drawing attention around the world. Governments of various countries have actively established cooperation between industry, government and academia to promote the development of offshore energy technology.
The OFPV project led by Sun Rise is currently the only one with a MW scale in the world. It is located at the open sea in western Taiwan and planned to co-construct with wind turbines in the future to improve the nature shortcomings to form a complementary effect of wind and solar. In addition, the project will also be planned to include the placement of oyster breeding cages and fish cages, to create an offshore energy park.
Through year-long field verification and extensive data collection and analysis, Sun Rise aims to demonstrate to the world that the system proposed based on past experience in fish cage and floating solar is mature, complete and ready.

Salt-corrosion
Suitable for CX+ environment
The entire area includes 4 blocks, and each block is 400m x 400m.
Each block is surrounded by a barrier, and inside sets arrays of floating solar systems (with panel facing east-west).
There’s no wind turbines in equatorial belt of calms, and 4 blocks are connected by shared anchoring to make a 100MW-project.
According to the power generated by the wind turbines, floating solar blocks with corresponding capacity are set up between the wind turbines. The layout of the floating solar system is staggered with wind turbines and navigation channel to ensure O&M safety.
Fish cages are set up between floating solar blocks to increase the utilization of no-navigation zone and balance green energy and fishery development.
Floating power system
The barrier is equipped with offshore waterproof and earthquake-resistant inverters and transformers. It is the first time in the industry that transformers are placed on a floating solar system.
Wind & Wave Resistance Design
Wind-reduction board-Wind-reduction boards are installed on the barrier to effectively weaken the wind speed and reduce the wind exposure of the solar panels in the project site.
Wave-reduction barrier-The tubular structure at the bottom of the barrier effectively absorbs wave impact.
Wave-reduction base support-The base support of the floating solar system is composed of wave-reduction gaps. Through its gaps and arc-shaped tubes, the residual waves of the barrier are effectively broken down.
Green Energy & Eco-friendliness
Green Energy-Artificial fish reefs are placed under the floating system, fish cages are set up between blocks, and oyster cages are hung at the base of the barrier. In addition to increasing economic benefits, it also has the effects of carbon sequestration and water purification.
Eco-friendliness-The floating solar system is made of 100% drinking-water grade HDPE material. The structure is designed with the principle of low coverage and high oxygen permeability, so long-term use will not affect the surroundings.
Anti-Corrosion Material
Anti-corrosion & Weather-resistance Material -The base is made of HDPE, which is highly elastic, impact-resistant, anti-corrosive, and UV-resistant. The service life can last for +50 years.
O&M Safety
The barrier handrails and anti-slip walkways are laid to improve the safety for workers.
Wind-Solar Hybrid
The capacity of the floating solar system can be flexibly matched with the power generated by wind turbines, and the power can be stably output regardless of the weather, thus it makes a wind-solar hybrid. Via co-construction with submarine cables, it can largely save construction expenses.
Large-scale Commercial Design
With unique anchoring design and high-duty components, blocks can be connected in series to make up to 100mw. It significantly reduces anchoring costs.
