We visited Singapore Polytechnic to meet Mr Dilip Battul, principal lecturer and our designated point of contact for the Solar Lab. Our next step was to decide on a good location for our off-grid solar installation. Unfortunately, Jos was not able to make for this meeting as he had fly to Thailand the week before.
Enjoy your tom-yam soup Jos, we've taken lots of photos for you!
Mr Battul brought us to possible site locations at the rooftops of T-12 and T-22. The existing 20kWp solar installation at T-22 was known as the Solar Energy Farm. There were about 300 PV panels, 6 solar trackers and also 2 wind turbines on that rooftop.
Interestingly, this solar installation had been constructed since 1998 and must have been one of the first few major PV projects in Singapore!
The rows of PV arrays. They were built facing north, but its not much of an issue since we're sitting so near the equator:
The Siemens PV modules used:
The battery room, and housing for all the peripheral equipment:
T-22 seemed quite promising since there was still ample roof space for additional PV systems to be installed. We might also be able to use some space inside the existing battery room for our system:
We also took some time to visit the second possible site at T-12, which was the School of Electrical and Electronics Engineering. The roof area was less than that of T-22 but more than enough for what we would need for the telecom testbed.
However, the problem with the T-12 roof was that it didnt have a sealed room where we could store our batteries and equipment.Our next step forward is now to get official clearance from the SP Estates Department for the solar project, which Mr Battul would be helping us with.
Stay tuned for more sunny updates =)
