| Solar thermal energy used for |
The solar thermal system was installed before the conventional heat source. It was necessary to open the circuit between the make-up water and the con-ventional heat source (steam boiler). Once the circuit was opened Thermal energy storage was installed

Lessons learned |
|
| |
| Initiative |
The customer (producer) had the initiative for fuel saving by using our PTC solution.
|
|
| Integration methodology |
The point of solar thermal integration was determined based on the available rooftop for installation, economic parameters and temperature requirements.
|
|
| Crucial Interfaces |
Designing / Tendering / Procurement
What are the most crucial interfaces? What are your experiences / lessons learned? The selection of process components like piping, storage tank, hoses and pumps has to be made according to the customer’s application requirements. We learned to use high safety factors for the selection of components in order to support possible bad usage from the customer like: stagna-tion in the PTC receiver, lack of cleaning and maintenance on the PTC and the use of non-filtered water through the hydraulic circuit.
|
|
| Construction / Commissioning |
Our experience was very positive as we achieved the ex-pected results for our customer. The main challenges were the proper guidance for the people in charge of labor and installation to achieve a good quality construction of the complete system.
|
|
| Operation / Performance |
Completely. The system performance overtakes our expectations. The solar thermal system works according to customer requirements reaching temperatures about 100°C.
|
|
| Recommendations |
We would recommend systems dimensioning according to customer’s temperature requirements with the appropriate solar technology, in this case PTC were the most effective solution for the customer’s 100°C temperature requirement.
