● Selective absorption film technology that efficiently converts the sunlight into the heat energy, that is Okitsumo Solar Paint.
Selective absorption film maximally absorbs the solar heat energy in the infrared region of sunlight emission spectrum, and prevents the heat release loss of conserved heat energy to the minimum.

<Features of Okitsumo Solar Paint>
This is the only system in the world that can provide the selective absorbing film by a painting method.
Excellent durability that can withstand harsh conditions outdoors as the flat- type solar collectors.
Selective solar absorbing film is easily available with the ordinary paint equipments.
A thin film layer of Okitsumo Solar Paint excels in cost performance.
It is applicable to the aluminum, stainless steel and copper substrates.
It comes available in 2 colors, black and navy blue.

To improve the absorption of solar energy to the surface of a solar heat absorption panel, black paint is usually applied. General black paint absorbs solar heat well, but when the temperature of
a heat absorption panel rises, the heat radiation loss increases and eventually the
collection thermal efficiency lowers.
Solar PaintGSP efficiently absorbs the sunray and has a charasteristic of losing only little heat radiation from a once heated heat absorption panel.
