Panel is rated at 50watts, originally intended for the 21ah batteries.

I'm going to get a new 90watt or 50watt panel... to pair with the larger battery, haven't decided which yet.

Finally figured out how to use a multimeter this is my first time.

The batteries after a full days charge reads 13.4v at rest. When the batteries are on load its 12.7volts.

Amps pulled by the lights is 1.5amps.

I'll measure the battery voltage in the morning after its powered the lights and switched off.

Wind turbines are interesting, I've researched wind turbines and can honestly say its very challenging!

===========================================================

For all multimeter newbies (like me) the following video is very helpful

Guys .. Check this out. The ultimate Green Energy Generation

On a lighter note....

Human batteries, tried that in the Matrix. Didn't work so well

IMHO wave energy is still in the R&D or early stages of development, would probably be some time before its adopted commercially.

The mechanical and electrical is no problem for me. But the electronic side like what is the correct component to get is challenging for me. I m electronic noob.

Any pro electronic here?

can i say jalan pasar ? lol

you guys really gonna install a miniature wind turbine ??

I need pro electronic guy who can teach me how to convert the wind turbine generate voltage to DC usefull voltage that can charge the battery or run some DC thing. I watch those youtube that only said some diode or rectifier or capacitor.

But all this component have some spec and number. So which 1 is which 1 should I get.

Try use Power transistor IC to have constant Voltage. LMZ is good example.

rmbr to put a speed limiter on the turbine ya

else = overloadddddd

I have no idea how to use at all.

Here some servomotor that can use as wind turbine. Some good, some spoil.

Added on January 13, 2012, 3:08 pmPut some gearbox?

What I know is, you need to dumb the load to some power resistor if your battery is fully charge.

I'm wondering is it a good idea to mix and match solar panels from different manufacturers?

No problem. If you connect in parallel, makesure the voltage is about the same. Any Amp doesn't matter.

Parallel - Amp + Amp = Total Amp. Voltage same.
Series - V + V = Total voltage. Amp same.

Just make sure wind turbine don't fail like this:

Wah, scary man.

Got to change design liau.

If you have this big of turbine, you going to power your neighborhood houses too.

Brake failure happens, during high winds a wind turbines can spin itself to destruction.

Personally I like the look of non-traditional vertical axis wind turbines, they're are less visible and compact. Some are beautiful to look at







I've seen a large vertical axis wind turbine installed at Puchong (not sure of working demo unit) but the turbine is barrel shaped. Will take a picture when I pass by it again.

TNB report losses again,

better hurry up in building our own power resource...

wind turbine doesn't really work in our environment as the wind velocity here is not suitable to generate electricity. go with other options.

if you stay on island or near the seaside.. wind turbine is a very good option..

for us who is not near the seaside.. solar is still the best bet

whats the highest efficiency for solar panel now days.?

and also the average solar panel pricing within reach and their efficiency ?

No need so kiasu lah. Even raise the teriff, still cheaper than solar here. Cause we still in subsidy.

the highest efficiency of production solar panel can be in the range from 15-18%. now the average price per kWp system is in the region of RM10k-RM15k depending on brand.
