Solar energy platform on slope roof

The utility model relates to a solar energy-absorbing device, in particular to a sloping roof surface solar energy terrace. The technical proposal of the terrace is that the sloping roof surface solar energy terrace comprises a roof surface component provided with a dovetail groove, and is characterized in that a solar energy heater is arranged in the dovetail groove, the solar energy heater is connected with a water tank or an inflow pipe and an outflow pipe. A separating plate is arranged in the dovetail groove and the dovetail groove is covered with a transmittance plate and the solar energy heater can be a solar energy vacuum pipe, a flexible metal conduit, a calandria or a thermotube. A reflecting plate or a heat-sink shell is spread in the dovetail groove; the utility model fully makes full use the structure of a roof groove furrow plate, is combined with the existing solar energy-absorbing device, and proposes a new train of thought for changing and using the roof.
