Thailand, Sai Ngam's Church

At Chiang Mai, we manage to find a local solar supplier of SHARP Solar Modules (130W). We bought 2 solar modules and a GEL Deep Cycle Battery 12Vdc at 200 A-H.

We arrive on Sai Ngam's church in the afternoon of 17 January 2010. We quickly prepared the mounting for the solar modules. We used a mixture of aluminum C channel rods and tree trunks to mount the solar modules. The solar modules are securely seated on the tree trunk.

Next we mount the charge controller, inverters, battery and the distribution box.

We started installing the lamps, altogether 7 CFL Lamps, 11 Watts each.

We also provide earthing protection for the system.

Final completed system with the lights turn on and picture taking. We completed the whole project in one and a half days.

Thailand, Doi Philu 02

I have gone back to Doi Philu on 17 January 2010 to repair the Solar Lighting. I have replace the charge controller from Phocos to Morningstar, Prostar 30. This charge controller is able to provide the solar charging current, the battery voltage and the load current. It is easier to troubleshoot with the meter readings.

At night the village chief tested the system for 4 hours, it work well without problem.
