The expected generated output by the 20 kW solar battery system at various direction and angle of installation was made a trial calculation based upon the quantity of solar radiation data from Owase City near-by Gokasho Bay shows Figure 15.

　

Figure 15 Expected generated output by the 20 kW solar battery system

　

When the power generated at the prototype is supplied to the loads thereon, it was considered reasonable to understood that 60% of full power be feasible to be used in consideration of the efficiency of inverter and batteries. Therefore, it is 2.5 hours that is the possible time per day to supply electric power for the road of the prototype subject to an inclination of 30 degrees on SE direction of the solar battery system.

In this year, we will study thorough on the hybrid power generating system to use 10kW of the solar battery system that will be installed on the prototype.

　

4. Conclusion

In this paper, it described on research and development of the offshore floating type wave power device "Mighty Whale" and its multi-purpose utilization.

The effects to be expected from these research and development show as follows.

(1) To propose a small-scale distributed energy source compatible with the environmental and an offshore floating type wave power device that dose not obstruct sea water movement, while creating a calm sea area, will become possible.

(2) Development of seawater purification system or deep seawater drawing system utilizing wave energy will become possible.

　

In the future, by clarifying the results of the open sea tests, the technological problem under these experiments will be solved, the practical application seems to become possible.
