Hello weikee do you know where to purchase good quality outdoor cables? I've been asking around but most electrical shops don't have what I'm looking for.
Managed to find a battery specialist shop called Volga at Bdr Puteri Puchong. Just picked up 100AH 12V GP brand battery today. Cost RM650  |

QUOTE(aaronpang @ Jan 6 2012, 02:48 PM) IMHO FiT in tariff is one thing, are there any competent and certified installers. This kind of project is songlap project lah. It not mean for usage.Take a look this article, simple setup yet the systems don't work. Botched projects will cause confidence drop and hinder future adoption of solar systems. Solar-powered lights at bus stops malfunction soon after being fixed MORE than 80 solar-powered lights at bus stops in Kajang, Cheras and Semenyih malfunctioned within three months after being installed. Kajang municipal councillor Eddie Ng said only eight out of the 96 lights were functioning and the rest were not in working condition. Ng said the lights were installed at the end of 2010 and in less than three months many had malfunctioned. » Click to show Spoiler - click again to hide... « Dua sen I could probably do a better job DIY the lights than those contractors  Sauce: http://thestar.com.my/metro/story.asp?file...862&sec=central My housing area have several solar powered street lights for the community park. Originally installed by the developer, most are functioning 5 years after they're originally installed. Others appear dead, no maintenance probably need to change the bulb or battery. Has anyone tried to DIY their own solar projects? Share your experience, tips and equipment used.  |

Don't know. I use 3M +33 Vinyl tape to protect the cable, than put it into a grey PVC pipe. This is what I did when I run expose wires in my mother house. I pull a direct cable from ground floor unused AC socket all the way to first floor toilet. Wire are expose. So far 6 years now. Still running good.Managed to find a battery specialist shop called Volga at Bdr Puteri Puchong. Just picked up 100AH 12V GP brand battery today. Cost RM650 |

imo, solar power is cheap, but the expensive part is actually the battery and high power DC-to-AC power inverter.

The world now produce exccessive solar panel. China are dumping the solar panel out and cause the price getting low. Which angry the US side and see some US manufacturing close shop.
In US during holiday sale last month, can see as low as $1/watt panel. I guess it is china panel. Hope you guys got grab some. At here, price range around RM9/watt and above. Probably tax and shipment cost which doesn't make sense at all. |

And yet get 1 panel also difficult to find. And no shipment cost involve at all. It should be lower cost.Since gov promote RE here, at least should abolish the solar tax for the local consumption. It benifit the local and the manufacturing here. No money is flying out. Songlap people money only.  |
