Okay.
Solar lights on Taobao are reliable. Because for solar lights on Taobao, the solar lights sold on Taobao are sold by regular solar light dealers who have been officially reviewed by Taobao, and after users purchase solar lights on Taobao trading platform, Taobao also We will provide quality guarantee for the solar lights sold.
I think it is better to buy bulky items at home directly in specialized stores or companies. Product quality assurance on Taobao is a problem.
The first question: the brands you mentioned None. of them are mainstream products, compared with Huangming (flush-mounted type), Tsinghua Sunshine
(flush-mounted type)
, Samp (pressure-bearing type), Soller Sunshine (pressure type), there must be a big difference.
The dsecond question: the more pipes there are, the greater the capacity of the water tank will be. Smaller manufacturers generally don't make large capacities.
The third question: The installation of solar products is more important than the quality of the product itself. Three points for the product, seven points for the installation. The places where problems occur most often are piping components, which are not easy to install or use.
The fourth problem. After-sales service is very important. Solar energy without repair or maintenance is like an orphan. I don't know how to fix it myself. This industry is not very mature and it is difficult to find maintenance personnel.
