Lessons learned |
|
| |
| Initiative |
Sunil Health Care was responsible for the initial startup. Rising Diesel prices, Corporate social responsibility, rising awareness about solar thermal technology and its benefits.
|
|
| Integration methodology |
The only hot water requirement in the manufacturing process was the preparation of gel. It was previously supplied by a diesel hot water genera-tor. So a solar thermal system was designed to replace this hot water gen-erator and supply instead with solar energy.
|
|
| Crucial Interfaces |
The most crucial interfaces are the factory manager who has the overview of the processes and the system design engineer of the technology provider. A thorough understanding on the part of the system engineer ad a detailed discussion with the factory manager is required to produce an efficient system.
|
|
| Construction / Commissioning |
|
|
| Operation / Performance |
|
|
| Recommendations |
Since Monitoring is not a part of the design at all, It should be considered during the design of the system itself. Care must be taken to ensure that the storage design is optimum and the use of 2 big storages resulting in heat loss must be avoided.
