this is economic prosucts , th flat panel are the absorber of the solar water heater.
this material
1with a controller amd heat exchanger(inside tank):cooper coil.
2inner tank:SUS 304-2B stainless steel with anticorrosion.
3out tank:colored/enamel/stainless/fluorine carbon steel.
4braket: Galvanized steel, aluminium alloy, stailness steel

5 Auxiliary energy :Electric heater.
this product feature:
1 the compact pressurized solar water heater system can endure the Max pressure up to 0.6 mpa.as the system is presssurized, so it can keep a contant temperature of water in the tank.

2The flat plate split solor collector system, using a circulation pumpwith a conteoller to circulate the fluid in the closedd loop system. storage tank and solar collector are separated, the collector is integrated with the building perfectly, while the tank and the pump station can be installed anywhere in the bulding.
3it can endure the freezing-35degree centigrade and 25mm hailstone.

4 this flat plate sollar collector lenth 2,000mm, and width is 1,000mm,thickness is 80mm. capacity 150L-500L.

This solar panel parts

1Frame material is aluminium alloy.

2Riser pipe:8pes.

3absorber plate.absirptance>95% allow to 2% more or less.

4Insulation layer

5Back sheet material like the frame.

6Tempered glass,thickness is 3.2mm or 4mm.

7heater pipe.

this solar collector is a metal box with a glass cover(called glazing) on top and a colored absorber palte at the middle. the sides and bottom of the collector are ususlly insulated to minimize heat losss, sunlight passes through the glazing and strikes the absorber plate, whick heats up. changing solar energy into heat energy. the heat is transfrred to liquid passing through pipes attacked to the absorber plate.

Other item:
1 Minumum order quantity36sets for 20"container.
2 delivery time is 2weeks after the deposit arrived to the seller's account.
3shippingment : FOB SHANGHAI , or CNF and CIF destination port .
4packing :our of foam and carton.
5 if you need the sample, the packing is foam +carton+wooden case by shipping, besause if it by air, we are afraid the vacuum tube will be broken. bring large waste to each other.so by the shpping is very safely and economic.
Characterstic
1affordable solar heating solution.

. 2easily integrated into existing heating systems.

3 Suitable for domectin and commerial hot water.
