Savings from oil and coal importation
Nag invest sa solar wala pa ring savings??!!
Savings from oil and coal importation
1. Hindi nagkuwenta ng actual load ng bahay. No se cuenta, no cuenta. (If you dont compute, there
is no value...
2. Low quality components
3. Nagtipid
Sizing up, computing for your solar power requirements
Savings from oil and coal importation
A shortcut, a hack on how to compute for your solar power requirements so that there is no under of over capacity, so that you will have set up swak for your requirements. Swakto
The size and cost of components to be computed are:
1. Solar panels;
2. The inverter
3. The batteries
4. Wires
5. Breaker
From what I understood, the following are the steps: (hacks)
1. Panels
1. Look at the electric bill Find the monthly kwh consumption. Say you found 449
2. 449 x 10 = 4490 = 5 kw/600 watts/penal = 7.48 = 8 panels
3. Panels required panels
2. Inverters
List down the watts requirements of the household.
Say you determine this to 5,200 watts/0.80 (for margin of safety = 6 kw inverter
3. Batteries:
Morning, pm, or balanced users. So you have choice of batteries:
100 AH - 50k
200 aH - 80k
300 ah -100K. Better buy th 300 ah battery for margin of safety in case of extended black outs or long period of low sunlight...
4. Wires
6,000 watts/230 volts = 26 amps
1, Wires for A C (connecting solar panels)
AWG 10 for 30 amps
2. DC = for 15.5 amps, puwede na 2.5MM but it is safer to use 4.0 mm
5. Breaker
A C side 26 x 1.25 = 40 amps
DC side 15.5 x 1.25 = 1938 = 20 amps
It is important always to consider safety (to prevent fires; solar panels are involved in fires because of overheating, BE ON THE SAFE SIDE.
Dont go for the cheaper side;
The other important factors are installation, delivery, and mounting which could be substandial.
The average rule of thumb price is P50,000 /kw So for 6 kw you need P300,000 budget which is far cheaper than P100,000/kw a decade ago
