4.Disk Stirling solar thermal power generation system and other solar power generation system competitive advantages

1. Convenient maintenance

Because the dish Stirling is a single module independent operation, any problems of one unit will not affect the operation of other units, compared with the trough tower is much easier.

2. Environmental protection

Disc type Stirling, trough type and tower type photothermal power generation adopts tracking system, which rotates with the sun track. It has no impact on the ecology of vegetation and crops at the installation site of environmental protection. Photovoltaic panels are not moving all the year round, and plants cannot receive light, resulting in vegetation blight and decay.

3. Floor area

(take 20MW as an example), solar disk type forest area: 480 mu (point land); Solar photovoltaic area: 1600 mu; Pv takes up 3.33 times as much space as a disc system.

5. Scope of application

6.发电成本分析

Economic Analysis and Comparison between disk Stirling solar thermal power generation and photovoltaic power generation (taking 20MW as an example) :

I. Comparison of power generation in life cycle (temporarily calculated as 25 years)

1. Solar disk Stirling: 933.45 million KWH;

2. Solar pv power generation: 652.88 million KWH;

3. The power generation of disc system is 1.43 times that of PHOTOVOLTAIC;

4. The service life of the actual dish Stirling is 30 years, with stable power generation and no power attenuation. (Photovoltaic decreases by 2% per year)

Ii. Investment payback period

1.20 MEGAwatt photovoltaic power station investment of 210 million yuan (including land purchase fees);

2.20 MW dish Stirling investment: 320 million yuan (including land purchase fees);

3.20 MeGABit Mutual photovoltaic power station investment payback period :11.45 years;

North tile disc Stirling investment payback period :9.73 years.
