I think, on a personal level, I am going to start trying to get solar systems set up for Khmers who may want / need them. I hate going up and down the road at the farm, knowing that, every night my family has power, while others are sitting in the dark.
I am currently in negotiations with a company to build a solar controller that will be reliable, yet much cheaper than your average controller offered by companies here. The controller would be manufactured in the USA. My first PWM controller here was $250 USD! This controller should easily come in under $100 USD, and will be customized for this project. It would still be a 20a to 30a controller, offering a 10a load circuit. It will be enclosed for the environment of Cambodia as well. So, it could even be mounted outside, if necessary.
I am going to try to get a solar module (panel) manufacturer on board as well, Just Solar. If I can do that, the only significant cost then will be the batteries.
So far, my plan is to include the following in one package price:
PV Panel Parts
1 - 100 watts 12vdc PV Module
1 - 1.5" angle iron mount (could go with aluminum here if cheaper)
1 - Assorted hardware for mounting the panel
PV Panel to Controller Parts
5 - meters two conductor #10 wire
1 - Assorted hardware to secure the wire against the building
Battery to Controller Parts
1 - Custom PWM Solar Controller
1.5 meters red #10 awg wire
1.5 meters black #10 awg wire
1 - Assorted hardware to mount the controller and secure wiring against the wall
Controller to Loads Parts
1 - 12vdc - 50ah Deep Cycle Battery
2 - Brass Battery Bus Bars (to attach loads)
1 - 10a 12vdc fuse / breaker
1.5 meters red #12 awg wire
1.5 meters black #12 awg wire
1 - Assorted hardware to mount the bus bars and attach the wiring against the wall
If all goes well, this may actually come to life by the end of the first quarter of 2015.
