That is high bill. Run 24hr can cost you RM30+. sweat.gif

That is why now every time i want to do simulation and testing, got to power up and use, than shut it down.

please share with us ya smile.gif

fyi if anybody plan to bulk or get what ever from oversea.. please check with us maybe some of us can tumpang.. if its cheaper smile.gif

Too big may get custom attention. The Solar panel is not small for large watt. Maybe need to smuggle from Kulim biggrin.gif

How much is the 100AH battery? Why not get a normal Car battery? Say 2x NS60? Will it be cheaper? Or N100

Yeah, I know the Car battery problem, thought you only use 50% of the 100Ah.

What is the solar block you have? 100Ah full discharge take a large volume of solar block to recharge back in one day.

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

Long as it state? Or actually being tested ? Just like led, it last long but performance drop after continues used for few years. Brightness drop.

Now they use solar to boil water, the steam to drive generator. This are more economical and efficient. But need larger area. If got concrete roof maybe can consider ;-)

car don't pay you every month for 21 years.
some more, have to pay monthly installment and petrol

But you pay advance for electricity, and no guarantee of recovering. Car at least you drive and get to enjoy.

Highly doubt can achieve 600 per month unless is very very big panel.

From the same website:

Easy calculations for system size and cost:

If you know your average kwh/day or know how many kwh/day you would like to produce, a simple calculation will determine system size and cost.

System size in kilowatts (kw) = (kwh/day) / 4 hours (peak sun) x 1.43 (system losses)
Step 1: Divide average kwh/day by number of hours of peak sun, or (kwh/ay) / 4
Step 2: Multiply by 1.43 to account for system losses due to friction, heat, and other inefficiencies.

Example: What size system is needed to produce 20kwh/day?

20kwh/4h = 5kw
5kw x 1.43= 7.15kw
7.15kw = system size to produce 20kwh/day assuming 4 peak sun hours (11am to 3pm).


Making it in reversed, since we mention 4KW panel,
(4KW / 1.43) x 4 hours = 11.2KW, that is about RM 12.6 per day. about RM 380 per month. About RM 91k for 20 years.

This provided good sunshine all year yound, and no equipment faulty.

How much is the 4.8Kw pv complete installation?

Think that will need about 300sqft area
