Light solar building integrated wall

The invention relates to a light solar building integrated wall, which mainly comprises a glass board, a heat collection board, a light insulation material layer, a heat radiation board, a first circulating pipe, a check valve, a control valve, an exhaust valve and a second circulating pipe. The glass board and the heat collection board are inlaid in the outer surface of the light insulation material layer; the heat radiation board is inlaid in the inner surface of the light insulation material layer; and the heat collection board and the heat radiation board are connected through the corresponding circulating pipe with the check valve, the control valve and the exhaust valve. A heat-carrying fluid is controlled through the check valve and the control valve to circularly flow in a closed loop constituted by the heat collection board, the circulating pipes and the heat radiation board, solar heat is transmitted to an indoor space for heating in a heating season, the indoor heat is blocked from dissipating to a
