After comparison of several solar technologies the solar parabolic dish technology has been found most suitable for our purposes. The Scheffler Dish is a proven technology and WRST has 15 years’ extensive experience with this technology. 
The main advantages of the 60m2 parabolic dish with fix focus are: 
- Cost effective / high output 
- Relatively simple construction modular design
- Innovative thermal storage concept 
- Easy operation/ maintenance; all components available in India
- Inexpensive planar mirrors and MC-controlled tracking system
- Fixed receiver with no need for flexible high pressure joints
- No vacuum technology and no metal glass sealing
- Due to direct steam generation no heat exchanger and low parasitic loads 
- Efficient use of land; the dishes can be tightly placed 
- Power on demand and high efficiency due to cogeneration
