It is very convenient for solar power generation, and there seems to be some degree of effect. Not only installed, but after charging so as to hit sunlight strongly, the effect is good, but charging is weak only by installing, the effect is also narrowed to the range of about 2 m. As much sunlight as possible hit as much as possible, I removed it and use it after charging it.
If you used it in the field, it rained, the water level of the mud increased by a certain amount, water entered from the bottom of the instrument and broke down. Although it seems he had healed it if he had removed the instruments, it seems that the instruction book does not say that it is unusable on rainy days. If it seems that it can not be used even at a single water level, it can only be said as a useless instrument.
