My Personal 'Stuff'





Some pictures of a Solartwin solar panel installed on our Kitchen roof

Connections in the airing cupboard - the insulated pipes are from the panel. Red wire to top cylinder sensor is also visible


The little pump in the loft - mounted to reduce vibrations.  Also the black PV, and yellow panel sensor, cables


Installation nearly finished
No! there is no reflected heat
from the panel!


The panel, supported on a wooden 'A' frame.  A cross batten attached by the white bracket has held it down even in high winds


The Photo Voltaic (PV) cell that provides power for the motor is mounted at the top right hand corner


A view of the rear of the house showing the discreet appearance of the panel





The sun has gone down, but the temperature at the top of the cylinder - displayed on the Controller - shows that the solar panel kept the water very hot even when the central heating boiler was off (in August).



One point worth noting is that the pipes feeding the panel are far less visible, or totally unseen, when the panel is fitted on a sloping roof - which is the usual place for solar panels.


If you want to visit Solartwin's site, it is here.  It contains wide-ranging information on their innovative system, presented in an extremely straightforward and honest manner.

I purchased their DIY kit, which comes with very detailed and comprehensive instructions, and the materials supplied are of high quality.




When sourcing some extra insulation - needed because my panel is not directly on a roof - I mentioned the simplicity of the system, and was told by someone
'with 30 years experience in the plumbing trade'
that 'it would never work!'


Well, he was wrong! - It works a treat!
