1Energy demand and water heat absorption effectApproximately 60% of household energy is
low-temperature thermal energy.

The 1 mm water layer absorbs almost 100% of far-infrared radiation.
*Far infrared radiation, also called heat radiation, is an electromagnetic wave with wavelengths of approximately 4 - 1000 μm.

2Heatlle Panel Features
1. what is the purpose of development?
We provide solar systems that users can build, use, repair, and improve.
2. why heat?

(1) Approximately 60% of a household's energy is thermal energy below 42°C.
The reason is that the energy conversion efficiency is approximately 50%, which is higher than that of electricity.
3. why hollow polycarbonate?
Superior in terms of heat resistance, durability, workability, and versatility.
4. what are the characteristics in dissemination?
We aim to promote this business as an energy-creating business that revitalizes local communities.

1. 2 heatl panels: Light-receiving area = 3.28 m2
2. solar-powered heat-resistant pump: 15 W

Off-grid type solar heat recovery system All can be DIY

5. Stainless steel heat exchanger:
throw-in type

1. 2 heatl panels: Light-receiving area = 3.28 m2
2. solar-powered heat-resistant pump: 15 W
3. Solar cell for pump drive: 12W
4. circulating water tank: double-layered structure, with trash removal mesh
5. Stainless steel heat exchanger: throw-in type
The pump is directly connected to the solar cell and starts running at sunrise and automatically stops atsunset.
Also, it hardly moves on cloudy or rainy days.
*Heatl panels are available as kits due to the rising cost of shipping.
Therefore, we will ask you to purchase two sheets of hollow polycarbonate at your local home
improvement center, etc.

It can be used as an auxiliary heat source for the house.
In progress:
We are currently promoting energy conservation in strawberry greenhouses.
It heats water in a 3-ton water tank to increase the temperature around the strawberry crowns.

Usage in inshore aquaculture fisheries
It is used as an auxiliary heat source for fishponds.
Stainless steel flexible tubes are placed in the fishpond and heated.
By attaching a temperature controller, the pump can be stopped at a certain
water temperature.
Suggested Use: Eels, shrimps, etc.

Eel farming requires a water temperature of 28°C even in winter.

It makes it easier to work in the greenhouses
during the summer.

Suppresses CO2 emissions fromthe house ceiling.

Do different plants have their own preferred colors?
Three safe and inexpensive food coloring materials

By coloring the water black, the heat collection efficiency of transparent panels can be greatly increased.

9Use as a heat exchanger in the building envelope
If there is a river or ocean nearby, the entire building envelope can be cooled.
A 1 mm layer of water absorbs almost 100% of infrared radiation above 3 μm.
Proposed use: factories and other buildings adjacent to rivers and the sea

Rooftop slab installation is not a problem to theextent that people walk on it.

10Usage as permaculture
When water is circulated in fishponds during the day, oxygen is created throughphotosynthesis.
This oxygen can nitrate ammonia and decompose organic matter.
As shown in the figure, a planting pipe (MGS) can be inserted into the flow path tocreate a hydroponic cultivation system.
Proposed use: Agriculture + Fishery collaboration system

Algae cultivation and use as photocatalytic panels
Enables algae cultivation in closed
It can also be used as a testing device for photochemical reaction systems.
Proposed applications: Chlorella, oily algae culture, photocatalyst, optical filter, etc.

Oily algae: Botryococcus

12Use as a heat source for wastewater treatment
It was used as a heat source for denitrification tanks in livestock wastewater treatment.
In normal wastewater treatment, the water temperature is increased to increase microbial activity.
The thermal energy is input because it is necessary.
Proposed application: Use in reaction tanks at general wastewater treatment plants

13Easy to use - (1)Directly connected to the faucet as part of the hose
It can be used to produce hot water from a hose placed in the sun.
What makes it different from a hose is that the hot water keeps coming out.

Suggested applications: showers at beaches and campgrounds, snow melting, etc.

Easy to use - (2)This is a natural circulation type utilization method that takes advantage of the difference in elevation.
The hot water is stored in tanks on the slopes and used.
If you have a slope on the south side, by all means, try it.
Suggested use: Flo of mountain huts, etc.

servicing
Part of a panel at the Kamifuse Test Site, Oyado Town, was damaged and repaired due to strong winds from Typhoon No. 9, which made landfall in Tateyama,
Chiba Prefecture, on August 22, 2016.
Situation: As a result of the rope breaking off the heated panel that was suspended by a rope, two nozzles to which hoses were attached were damaged by windpressure (see photo above).
In addition, two scratches were found on thelight-receiving surface, probably caused by flying debris (see photo below).
Repair:Photo above: The nozzle with a broken threaded part is stripped with a spatchera and the silicone is scraped off, then replaced with a new nozzle. (Working time:about 15 minutes)*Measures: Reconsideration of glass fiber content in materials has been initiated.
Bottom photo: The scratched light-receiving part is repaired by cutting a square piece of hollow polycarbonate (transparent) and pasting it over the lightreceiving plate. (Working time: about 10 minutes)
