Solar PV - Sonnenkraft VK25
Features of Sonnenkraft Solar PV evacuated tube collector VK25
Higher output due to vacuum insulation
High temperatures – even in poor weather conditions
High output due to exploitation of diffuse and oblique radiation via CPC reflector and circular evacuated tube absorber
Simple maintenance – tubes can be changed without having to drain solar circuit
Simple assembly process – low assembly costs
High output even at lower outside temperatures
Sonnenkraft VK25 evacuated tube collectors ensure high output at low outdoor temperatures, particularly when used with heating systems. They are delivered as prefabricated modules for roof mounting.
Collectors consist of;
Evacuated pipes including absorber.
Works Well In Low Temperatures
Uses vacuum insulation ensuring high output and high temperatures – even in poor weather conditions, like low outside temperature.
It's easy to change the tubes of the VK25 without having to empty the solar loops.
The Sonnenkraft VK25 has high output due to exploitation of diffuse and oblique radiation. This is used via CPC reflector and its circular evacuated tube absorber.
