Tech Tech Corporation of Japan has launched the "Tech Spray System" which uses solar water to prevent the power generation efficiency of photovoltaic power generation systems from deteriorating at high temperatures.
According to reports, this system was the actual product of the "solar thermal sensitive valve and sprinkler device using the same valve" that was patented in December 2013. Its characteristic is that the use of "solar thermal valve" can control the opening and closing of the valve without power.
The principle is that the heated part is heated under the sunlight, the sub-valve is opened, then the female valve is opened and the water supply begins. When the water discharged from the sub-valve cools the heated portion, the sub-valve will close and the valve will close, stopping the water supply. Only use the pressure of the water pipe to spray. Since this series of actions does not require the use of electricity, only water pipe construction is required.
