ACT-60, Melacs unique thermal ACT unit transfer the warm air from the baffle collector at the rear of the PVBT-1150 solar panel, and at the same time the air is compressed to 1,8 bar to be additionally heated with a factor 1 to 2-5. At the same time this process is working as a cooling system for the solar panel which is significantly increasing the panel efficiency and life cycle.

Each ACT-60 can handle up to 60 pcs PVBT-1150 solar panels, but each energy system can handle several ACT-60 units to match the desired total energy capacity.
