Sangle is probably the best of these brands in terms of quality and price
Huangming 30 tubes generally cost more than 1W5, and the advertising costs for major brands are also high
Siji Muge is from the same family as Taiyangyu. The after-sales service ratings of these two brands are not high.
Tsinghua Sunshine and Sanle are the first solar power manufacturers in China, but the products have not been improved and are still the same as 10 years ago.
Strap is. a solar manufacturer. It was done early and there is not much advertising, but the brand is still good and there are many outlets. Advertising costs are in addition to product quality and product research and development. Personally, I think it's good. choose Sanle, in terms of cost-performance ratio
