Solar PV workshop with EWB Edinburgh

I have been involved with Engineers Without Borders UK for around 4 years, after going on a one-year placement working on remote rural power supply systems for an NGO in the Philippines, called SIBAT.

EWB-UK is a student run organisation trying to connect engineers with the field of international development. They do this through placements, training and outreach programs.

EWB Edinburgh branch (they also have a web-page here) were running a 4 day event relating to Energy and International Development, with days on general development issues, solar PV, wind and water and sanitation. I was invited to run a practical session on solar PV, as I have done for the Royal Academy of Engineering and for the Small Is… Festival (run by EWB-UK and Practical Action).

The day started with talks from Milan Delor (on his access to energy work with Practical Action), Alistair Cook (on his placement in Bolivia) and myself. I spoke a bit about my time in the Philippines and projects I had worked on and issues that arose. I then covered basic theory relating to designing stand-alone power supply systems. The afternoon was then taken up with a practical session where in small groups each had to design and build a PV powered stand-alone power system to supply the load I allocated. The loads included a radio, lighting, mobile phone charging and powering a laptop. There were around 25 participants who hopefully had an interesting day.

OK, it wasn’t that sunny, but they did work.
