Product Introduction
Back Contact sunpower are an advanced design where the metal contact points are placed on the rear of the panel, not the front. This design eliminates the front metal lines, maximizing sunlight absorption and enhancing efficiency. Not only does this design enhance the panel's efficiency, but it also gives the solar panel a cleaner, more aesthetically pleasing appearance. Back Contact sunpower use high-efficiency monocrystalline silicon solar cells, which perform excellently in terms of energy conversion and can generate more electricity under less light conditions.

FAQ (Frequently Asked Questions):
Q: How long will it last? Will it deteriorate over time?
A: Our panels come with a 25-year efficiency guarantee:Degrades less than 0.5% annually for the first decade, and guaranteed at least 80% output by Year 25
Q: Do I need to shovel snow during snowy weather?
A: Not at all! The panel slope is designed to automatically shed snow once it exceeds 10 cm in depth. This has been tested and confirmed effective by customers in Northeast China.
Q: What is the payback period?
A:Calculated at the residential electricity rate of 0.6 yuan/kWh:
Sunny regions: 4–5 years to break even
Jiangsu, Zhejiang, and Shanghai regions: approximately 6 years
