The invention provides a solar water heater. The solar water heater comprises an insulation water tank, wherein the insulation water tank consists of a liner, a polyurethane insulation layer and a water tank shell connected in sequence from inside to outside; a baffle plate surrounding the liner is arranged on the outer side wall of the liner, and is provided with multiple through holes; a vacuum layer is formed between the liner and the polyurethane insulation layer; and the outer side of the polyurethane insulation layer is tightly bonded with the water tank shell. On the one hand, the solar water heater adopts the vacuum layer and the polyurethane insulation layer for insulation to achieve the better insulation effect; and on the other hand, the baffle plate arranged on the outer wall of the liner effectively prevents the deformation of the polyurethane insulation layer; moreover, the water tank shell tightly bonded at the outer side of the polyurethane insulation layer prevents direct exposure of the polyurethane insulation layer under sunlight, so that the service life of the solar water heater is prolonged; and the solar water heater has such advantages as simple structure, low machining cost and good insulation effect.
