1. Socket-high erosion-resistant 316L stainless steel, one formed by stamping moulding. No welding.
2. Overheating prevention in Summer and Higher sunlight absorbing in Winter.
3. Polished mirror CPC concentrators, parabolic curve sunlight accumulated, 360* vacuum tube absorber, much more power output than the normal solar collectors.
4. Superheat pipe faster startup, high pressure working, new structure nylon tube caps make the installation more easily.
5. Connection on tank backside, more convenient for the slope roof installation, safer by the special heating element box.
