Solarbayer CPC18 Nero Vacuum tube collector gross collector area: 3,26 m2

Solarbayer CPC 18 Nero high-performance
vacuum tube collector in vertical design
for on-roof and flat-roof installation,
integrated return pipe for connection on
one side. High-vacuum coated reflective
CPC mirror, glass tube with vacuum in
double-jacket tubular glass (thermos
flask system) with highly selective
AL-N/AL coating, each tube is individual
passed through according to Tichelmann,
thus lowest hydraulic resistance,
frame profile made of black anodised
aluminium, outgassing-free insulation
made of high-density mineral wool
