Cambridge Self Build Solar Team
Construction Weekend 15th to 17th March 2002
What were we doing?
Making 40 solar panels. These are 1 square metre in size. They sit on a roof facing the sun, and help heat up hot water.
Who was there?
Phil, David and Dave, who work for the Low-Impact Living Initiative (LILI). They run the course. Phil designed the panels and the system. They demonstrated the assembly process by explaining, showing, and doing.
Delphine, Ian and Gareth from the NEF.
Fifteen attendees. Do-it-yourselfers that were going to end up with some panels. My four panels worked out at £109 each - a bargain!
Ten potential punters, wanting to see what was involved. They worked as hard as everybody else.
What happened next...
A sample water circulation circuit was being used to demonstrate the entire system.
It had a couple of useful features. One was a mechanical flow meter calibrated in litres / minute.
The other was a simple gate valve across the cylinder coil, there to help bleeding air from the system. I may have to add that to my schematic.
Snowy, one of the attendees from the course, lent me some controllers to look at.
Cambridge Science Week (Not specific to Solar Panels, but was being held while we were at Cambridge making panels.)
DTI Press Release. "Brian Wilson, Minister for Energy, today [18/3/02] brought the reality of the wide scale use of solar power closer by announcing funding for public buildings which include schools, galleries, church halls and sports centres all over the UK."
