The price of flat panel wall mounted solar power is higher than that of ordinary rooftop solar power. The main reasons are:
1. Water tank: water tank type pressurized water. wall-mounted solar power tank, while the non-pressurized water tank type rooftop solar power water tank. In addition, the wall-mounted solar water tank is a double-walled water tank with electric water heater function
2. The collector part: Planar sensors mainly use copper plates and copper or copper-aluminum tubes. composite materials, while rooftop solar uses vacuum tubes. Take the heat directly.
3. Solar wall mounts conduct heat and do not freeze in winter. Solar energy on the roof directly heats the water.
For the reasons above, wall-mounted solar typically costs more than a doublingthe price of ordinary tube solar energy
