Wind Turbine Building Workshop with Hugh Piggott on 18th June

THE WORKSHOP IS NOW FULL

Hugh Piggott is coming back again to Ireland this year to teach another of his famous wind turbine building workshops. Go here to see previous workshops

The venue is in Co. Leitrim near Keshcarrigan.

NEWS: see below for the good news about the reduced workshop fee.

The course participants will learn many skills and also the theory involved in a domestic wind turbine. A domestic wind turbine will be built from scratch on the course. We will discuss various mounting systems, inverters and control systems, off-grid and grid-connected systems. At each stage of the process the participants will gain hands-on experience.

Each day consists of workshop sessions with opportunities to gain hands-on experience of carving wooden blades, winding coils and fitting magnets into purpose built alternators for windpower,  wiring, fabrication, erection and all aspects which can be covered as time allows.  There is a very minimal amount of formal classroom presentation, largely controlled by demand

these courses are to teach you how to build a wind generator, so please do not expect that you will go home with a completed wind generator.

This is a practical, hands-on course where the participants will learn to build a wind turbine from start to finish, participating in every stage of the process. The course should appeal to those with an interest in learning more about renewable energy, specifically wind energy and how to provide energy for the home or farm. Ideal for people from the farming sector, general public or professional trades people who wish to learn first-hand from people who have been involved with renewable energy for years.

Price for the workshop has been reduced from €350 euro, thanks to the Leitrim Development Co we can now offer places on the workshop for the very low price of €100.

Let us know if you need help finding accommodation or alternatively you can camp at the farm for free, just contribute to the food bill. There will be one meal a day supplied for course participants, plus tea and coffee.

Booking is €100 euro, payable as soon as possible to ensure a space on the workshop, send it to us here by cheque, postal order or cash to:

 

PV workshop at Irish Seed Savers in Scarriff, Co Clare

On the 11th February 2012 we ran a one day PV workshop at Irish Seed Savers in Scarriff, Co Clare. The hands-on workshop project was the installation of a photovoltaic 50w panel to charge a 12volt battery. This small 12volt system was to supply lighting for Seed Saver’s Cob House which had no electrical power. It was decided to use the system to supply electrical power to two low 4.5w 12volt LED light bulbs.

The workshop participants were eager to get involved and divided into two groups, one working inside to get started on the wiring for the lighting and the others went outside and were soon planning how to best hold the photovoltaic panel in position so that it would get plenty of daylight.

A battery box had been built to hold the battery and protect it from the elements. Soon we were on the way to constructing a frame which attached to the battery box and would hold the pv panel securely. Even better, the frame is adjustable so the angle of the pv panel can be changed to suit the seasons. It is advantageous, if possible, to have the panel angled upward for summer sun and angled lower to catch the winter sun.

Inside the Cob House the wiring was being put in place to allow for two lights, one at either end of the living space. The lights chosen were a pair of 12 volt LED lights. LED stands for Light Emitting Diode. These little light producers are really semiconductor junctions—diodes. The LED is designed so that the energy lost across its diode junction radiates as visible light. When it comes down to making light from electricity, the LED is three to seven times more efficient than fluorescent and incandescent lighting technologies. LEDs make more light using less power.

The charge controller and a fuse box were affixed to the wall and ready to take the cables from the pv panel, the battery and the lights. A cable was run through a hole drilled in the window frame and attached to the pv panel outside. The panel was wired up to the battery. All the cables were securely wired into the relevant parts of the the charge controller and disconnect switches.

When all was connected the light switch was pulled and we were all delighted to see the light come on.

Everyone had worked together and had taken turns to do the various parts of the installation. There were also times during the day when the different phases of the installation were being explained and then everyone stopped what they were doing to listen and ask questions, going back to their own particular job afterwards.
