7. new type solar energy heat generating system according to claim 1, it is characterised in that: hold over system (4) conduct The place for accumulating heat, using the reinforced concretes such as cuboid, polyhedron, cylindrical body structure or thermal-insulating body, rock wool board etc. is protected Adiabator and mixed mud My Perspective On The Co-building；Or high-temperature heat accumulation pond and low-temperature heat accumulating pond are set, low-temperature heat accumulating pond is in high-temperature heat accumulation pond Top.

8. according to claim 1, new type solar energy heat generating system described in 2,3,4,5,6 and 7, which is characterized in that it includes Outer heat preservation system (contain reflector), light penetration system, collecting system, heat-storing material, electricity generation system, the various pieces such as hold over system Can according to claim 1,2,3,4,5,6 and 7 be freely combined, form multiple optional high performance solars power generation systems System, power generation and heat supply heating system；New type solar energy heat generating system of the invention can be placed with North and South direction, can also be with south by east Or south by west direction is placed, and can be placed with east-west direction；New type solar energy heat generating system of the invention can be using single System also can use modularized design, realize extensive trans-regional power generation (heat supply).
