For many people, the communication power system is a strange word. In their minds, it was a magical device, and they had never used it before. Therefore, when buying him, they will have a lot of doubt, they will consider all aspects of the problem. Solar equipment is one of the first things many people consider. So what are the considerations when buying him? The small editor will come.
First, consider the local climate. Everybody knows the communication power system, it's not good to leave the solar energy. In one place, if the sunshine duration is not long and the ultraviolet light is not strong, then the absorption rate and conversion rate of the machine are naturally low. In this case, if you buy him, you can't get the effect you want. So, if the local sunshine doesn't last long, you need to do something else.
Second, consider the location of the installation. Whether you live on a high floor or at the bottom, the sun is the main factor. There is no solar power and there is not enough space. The device is still slightly awkward and cannot be moved. The site you install must be large enough to be soled by the sun for the maximum amount of time in a day, absorbing solar energy and generating hot water.
Third, consider the years of service. No device can ever be used, and the home communications power system is no exception. The life of each machine is different, when its efficiency is not high, the amount of hot water produced can not reach the effect, so long needs to be replaced. If you want to buy it, try to choose a machine with a long life, which can save a lot of things.
