gtc-58s-alu 30 tube flat solar collector, solar water heater, solar collector, solar heating system, solar, solar water heater

GTC -58s-alu 30 tube solar collector type is our new design for house and projector installation,like vila,bath, room heating,central heating,factory doom,wool washing,sunna bathing,pool etc.
our solar system are designed connecting with the gas heater or rediator or electric back ing up system.
gtc solar make lots of project like some five star hotel, united union projector, and green house project,.....etc.
gtc solar always make our solar sytem with better quality and new solutions and new technology to make our solar sytem get more efficiency, always thinking ways out for our customers to make new designations and new products,producing and designiing according to customer's requestment and give solutions .
