VACUUM solar collectors

SP models

SP12, SP15, SP20

Cold stable efficiency: the great thermal isolation and the innovative design of the reflective elements  are efficient for solar collectors SP12, SP15, SP20 even to cold outside temperatures.

The most from every square meter: SP12, SP15, SP20 collectors give the highest energy productivity in the category with the same encumbrance space up to 700 W/mq.

Energy at any time of the day: SP12, SP15, SP20 collectors manage to capture the diffused brightness and the oblique rays because the cylindrical surfaces of the pipes they amplify the useful surface.
