EE students from PUP Sta. Mesa Manila attended an advanced tutorial on solar powered cellphone charger.

EE students of PUP Manila

They were thankful that they were able to saw one of our ad online about solar cells for sale. At first they only asked to buy cells for their solar powered cellphone charger project, and asked a lot of questions. We decided then to offer an advance tutorial for them so they can understand better. Asking for directions on how to get here at Gen. Trias Cavite, they scheduled for a tutorial Feb 1. They came a little bit behind the time scheduled but everything was ok considering how far they came from.

This tutorial is more of hands on and less lecture. We did have a little bit of lecture on solar cells and solar power works since they don’t have wide knowledge on it. After that each one of them were taught on the tabbing techniques, how to correctly tab cells and how to assemble their project. Everything from tabbing to framing to making the housing for the USB module was taught and done at the same day. This is so that they can be guided accordingly and made sure they will go home with a “working” project and knowledge about it so on their defense they will be able to easily answer questions.

Each one gets to try tabbing the cells.  They have to tab 10 solar cells of 52x19mm in size.  It took a while to get it all tabbed as none of them were used soldering yet :)..  There were a few solar cells that got broken, well it’s part of learning.

After all cells were tabbed, lots of picture taking for the thesis, each column were tested for voltage output and then the 2 columns were connected and tested again, this time under the sun..

After all cells were tabbed it’s now time to frame it – make it into a solar panel.  Here they are all helping to frame their project.  They finally now have their solar panel, but it’s not done yet, they still need to connect the USB module.
