Q: What about solar products?Solar panels solar panels: As long as the need to get electricity can. Solar lamp (lamp, landscape lamp, lawn lamp, flashlight, camping lights, lights and so on...), power generation system (Canada now many private power, is the placement of solar panels in the roof)...

Q: Buy solar water heater mainly look at what?: Such a water tank, not only poor quality, but also may cause damage to the health of consumers with bacteria. Third, insulation layer. The quality and thickness of the insulation layer determine the insulation effect of the water heater. Now on the market most of the solar water heater using polyurethane foam insulation technology, but also the polyurethane material, but also the overall high pressure foam and low pressure foam. Large enterprises using the overall high-pressure foam to ensure the pressure and fullness of foam, a lot of small manufacturers of low pressure foam will be part of the insulation layer of the phenomenon of incomplete.
