Why choose our solar panel is you ideal choose?
1. The important raw material, Solar cells, come from domestic public company and Taiwan famous company. Quality assurance: 25 years long life span, Industry leading power output warranty 10 years 100%, 20 years 95%, 25 years 85%.
There are some company which select inferior solar cells that are processed from recycled silicon material from small workshop, so their solar panel service life maybe less than 5 years because inferior solar cell power reduce much more every year.
2. Our company has automated production line for solar panel. Good technology, good quality assurance. Strong production ability: 300 pieces 300w solar panels can be manufactured per day. Most of company weld solar cell with artificial manual work. Bad manufacturing technique is difficult to keep consistency of products.
