- Solar panel:
200-watt = P3,300~4,500
100-watt = P 1,800~2,800
50-watt = P1000~P1,500
20-watt = P600~1,000
- Inverter:
1kW off-grid (recommended)
(Pure sine wave) = P3,000-P5,000
(Modified sine wave) = P1,000-P2,000
Grid-tied (can send electric power to the provider):
with built-in MPPT
P7,000~P15,000
- Battery
LEAD ACID (Valve regulated/sealed type) (3 year max lifespan)
= P900 = 16AH/12V
= P3,600 = 64AH/12V
= P6,000 = 100AH/12V
= P11,500 = 200AH/12V
LiFePo4(10 year max lifespan)
= P100-150 = 3.2V/6AH (1 cell/no BMS)
= P12,000-13,500 = 100AH/12 (full setup)
- .Wires
(16 AWG) = P14 per meter (recommended)
(18 AWG) = P10 per meter
(22 AWG) = P8 per meter (for low amperage)
(100-meters roll) = P200-300
- Charge controllers
PWM = P160-P200 (60-75% efficiency)
MPPT = starts at P3,000 (95-99% efficiency)
MPPT buck converter = starts at P1,000 (no built-in temperature and/or battery charge detector)
di malaki budget ko kaya simple lang set up ko:

600-watt Solar panel
P2,800 per panel (150Watts)
= P11,200
VRLA Battery 1200WH
= P5,500
Inverters
= P2,700 (1kW Pure SW) for heavy motors, rice cookers, heaters, flat iron etc.
= P800 (500W Modified SW) for chargers ,LED lights and clip fans only
PWM charge controller
= P400 2 pieces (30A)
Wires
= P168 - 70 meters (22 AWG)
= P250 - 30 meter (16 AWG) for solar parallel connection
TOTAL:
P21,018
Return of investment (ROI:
max power produced (600W)
average sun production (6H)
efficiency (65%)
Power produce in Kwh
Per day:
600W × 6H × 65% = 2.34 KWh
Per month:
2.34kWh × 30D = 70.2kWh
Average monthly kWh usage 1 per household (150kWh = P1,800)
Monthly production (70.2kWh = P842.4)
ROI = Total investment/monthly production
= P21,018/842.4
= 25 months or
~2 years
ang mapapalitan mo lang sa loob ng 2-3 years ay ang battery.
halos 10-15 years kasi lifespan ang inverters/solar panels lalo pag high quality
So bale in 2 years+ libre na yung kuryente, siguro nasa P100-200 lang yung maintenance per month.
