At present, the mainstream balcony wall-mounted solar energy, what brand is cost-effective? Huang Ming, Four Seasons Muge and Zhongke Lantian are currently choosing these three companies. Hurry up!

Zhongtian Technology has never heard of small brands, but as an engineer, you must consider the cost. After-sales things have been discussed, and the brand doesn't matter. As long as it is a qualified product, there are relevant test reports, and the brand with no problem in bidding can do it, but the quality is still guaranteed by big brands. It's not worthwhile for Huang Ming to be too expensive. Four seasons mu song is good, but the price will not be too low. I suggest you consider the installation and after-sales problems first. Otherwise, it's really broken and no one will fix it. Dude, you've been taking the fall. Installation of wall hanging must be professional. After-sales maintenance is useless and useless. If something falls again, it will be even bigger.
