Pioneer of blow molding
An innovative floating solar power generation system that combines many unique structures created by Kyoraku.
Based on the concept of MADE IN JAPAN production, we have created a unique special structure using the technology we have cultivated over many years as a blow molding manufacturer.
With outstanding workability and reliable safety, it overturns the common sense of floating solar power.
Since its launch in 2014, ”Minamo Solar System” has been favored by many customers, and has already accumulated many achievements in the field of industrial solar power, from low-voltage class to mega solar.
Product features
Proprietary technology float system delivered with confidence by blow molding professionals
Folds compactly for transport
The specially structured indicator plate is housed inside the main unit with a hinge structure, greatly reducing the amount of work required during transportation.
In addition, high work efficiency has been achieved by easily starting up without using any tools.
Fixed with resin bolts
The float is connected with two resin bolts.
The resin bolt is fixed to the float body at the time of delivery.
As a result, the fixing work is a structure that only tightens the nut from above, and it is possible to easily work with one hand.
In addition, since a part of the float also serves as a passage, it is possible to connect 3 floats at one connection point, realizing overwhelming assembly speed. A simple calculation shows that the assembly speed per 1 MW is -50% compared to other companies. (according to our research)
Realize free layout design
”Minamo Solar System” is designed with a simple configuration for connecting major parts such as floats.
This makes it possible to freely arrange the layout according to the shape of the pond, expanding the possibility of being able to handle ponds with a small installation area.
By preparing multiple optional floats, it is possible to respond flexibly to various situations.
Design of MADE IN JAPAN
In consideration of on-site wiring work, etc., the float has holes for fixing cable ties, etc., making it possible to bundle wiring cables.
No special tools are required, and wiring cables can be fixed only with wire and cable ties, so it works in terms of both safety and workability.
Response to long-term use as considered by 100-year-old companies
Uses a specially formulated resin material
A photovoltaic power plant must be designed on the premise that it will be installed for more than 20 years, and it is an extremely harsh environment for general resin raw materials.
For more than 40 years, we have used the know-how we have cultivated in outdoor toilets, canopy roofs for construction machinery (mini excavators), etc., and have adopted special resin raw materials that assume long-term durability for solar float mounts. .
Outstanding maintenance performance
Floating solar power plants require regular maintenance even after installation, and it is necessary to periodically enter the power plant to check various things such as electrical equipment, floats, and mooring systems.
At that time, our float boasts outstanding stability by installing a pier and having a unique float structure (a structure that supports buoyancy with multiple floats).
Therefore, it is a system that can be easily replaced even if the panel needs to be replaced due to damage, etc.
Strict quality control system
All production is carried out in our own factory, and in order to deliver safe and secure products to our customers, we have introduced an automated system that does not rely on humans as much as possible.
The concept is to create products that protect the pride of a 100-year-old company through strict management, such as checking the sealing of the inside of the float.
Environmental consideration for a sustainable society
Food container Same level of environmental performance
We are a manufacturer that manufactures and sells a large number of food containers using blow molding. We believe that the resin raw material used for the float must be environmentally friendly when it is used for agricultural ponds.
The raw materials used for our floats are produced with materials that meet the standards of the Food Sanitation Law and the standards of the Ministry of Health and Welfare, which are the standards for food containers in Japan.
Uses recyclable raw materials even after use
Our float uses highly versatile olefin resin. Therefore, after use, it is possible to remove, sort, sort, and recycle.
EX) Reuse for plastic pallets, etc.
By using materials that can be recycled after use, we believe that we can contribute to a more environmentally friendly and sustainable society.
Configuration of ”Minamo Solar System”
Module float configuration
A float on which solar cells are attached is called a module float.
At the construction site, assembly is completed with a simple structure that attaches the washer-integrated screw to the nut set on the product.
It can be combined with various module floats, and can be said to be a highly versatile assembly method.
Connection configuration between floats
Construction procedure

Lift the mounting support plate (middle plate) to mount the module
-
Raise the middle plate, temporarily fix it, and attach it to the main body nut with two cap bolts.
-
Assembly of float and module (1)
Attach the fixing bracket (lower side) to the main unit with 4 cap bolts.
-
Assembly of float and module ②
Attach the fixing bracket (upper side) to the main unit with 4 cap bolts.
-
Concatenation of various floats
Assembling module floats using passage joint floats
-
Array assembly on the shop floor
Connect up to a certain size according to the work space
-
Push the array into the pond
-
Towed by boat to mooring position and connected
-
Completed by fastening the anchor rope to the anchor float
Why water solar now? (advantages)
Contribution to society
Currently, various abnormal weather events (droughts, cold waves, heat waves, heavy rains, typhoons, etc.) are occurring all over the world, and one of the causes is said to be global warming.
Greenhouse gases are the main cause of global warming.
In order to prevent this global warming, Japan has declared to the international community that greenhouse gases will be -30% by 2030, and is trying to realize a decarbonized society aiming for net zero greenhouse gases by 2050.
It is very important to maintain a convenient social life in the future and to procure clean energy.
For that reason, Japan has a policy of actively introducing renewable energy, but Japan already ranks first in the world in the amount of solar power installation area per country, and Japan, which has a small land area, is greatly promoting development. The current situation is that there is little room.
Therefore, the government is also looking forward to the introduction of solar power in water space.
There are more than 150,000 reservoirs nationwide, and most of them are used only as reservoirs, so floating solar power generation, which can be installed while maintaining the current functions, is attracting a lot of attention. are gathering.
Contributions to Owners and Managers
Many of the more than 150,000 ponds in Japan are used for agriculture.
The population related to agriculture is on the decline, including the declining population of Japan as a whole, and many of the farms that are maintained and managed are aging, and there are many areas where maintenance and management are becoming difficult.
At the same time, by installing floats, it is possible to prevent the evaporation of water in reservoirs and suppress the occurrence of blue-green algae in shallow water ponds, etc., and there are reports that the generation of sludge and odors can be reduced. .
It can be said that there are many merits for owners and managers of floating solar power development that can obtain stable rental income by leasing the water surface of the reservoir without impairing the functions of the reservoir.
Contribution to power generation companies
The floating solar power plant uses the existing water surface and can be installed while maintaining the functions of the reservoir, etc., so it can be said that it is an environment-friendly installation site that does not involve large-scale development, and the cooling effect of the water surface. It has been reported that the amount of power generated is 14% more per year than that of a roof-mounted power plant.
Even at our company's own power plant, we have been able to obtain more power than expected, and we believe that it is a power generation method with many advantages for business operators.
