Project Summary

Description
The installation is formed by 48 SOLAHART collectors, mod. L, situated in a suitable area. The 48 collectors are divided into 8 batteries of 6 collectors. The system uses a variable temperature control which operates the primary and secondary circuits.
The collector heat is transferred to the storage tank by an external heat exchanger. The variable temperature setting to start/stop the circulation pumps is 6 C.
System use: ACS with a solar fraction of 80 %.
