1000 Watts is enough, take note this is a capacity. Pero kung gusto mo mas precise ganito calculation Watt hour.. So halimbawa ang clip fan m eh 25 watts..i times m sa average time mong gagamitin. 25 Watts x 5 hours = 125 Watts, so need m ng 125 Watts sa fan plng. Add m lng iba pang appliances m, na dapat below sa wattage capacity m yung actual na computation m sa load.
Next, choose the right
BATTERY, need mo ito, to stored the power dahil need m ng constant voltage.
Tandaan mo, the higher the voltage, the lesser the current and the lesser the copper loss will be in the conductor. This will also reduce your conductor size. Most of the small home solar systems will have 12 V or 24 V. Pra sakin gamit ka 12V.
Eto battery ratings sana makatulong:
Battery capacity is rated in terms of Ampere Hour.
Power = Voltage X Current
Watt Hour = Voltage (Volts) x Current (Amperes) x Time (Hours)
Battery Voltage = 12V ( as our system is 12V)
Battery capacity = Load / Voltage = 365/12 = 30.42 Ah
But batteries are not 100% efficient, assuming 80% efficiency
Capacity = 30.42/0.8 = 38.02 Ah
You can select a 40Ah deep cycle lead acid battery by taking some margin.
Next
SOLAR PANEL: Let's assume in 4hrs nka babad si solar panel sa sunlight during daytime,
So total power output of Panels = 12V x 40Ah = 480Wh
Power to be generated per hour = 480 / 4 = 120W
By taking some margin you can choose a 125 W, 12v solar panel.
Next
CHARGE CONTROLLER, inilalagay to sa pagitan ng Solar panel at battery, and purpose neto is to regulate yung Voltage and Current na papasok kay battery. Kasi take note, ung solar panel nag proproduce yan ng not only 12V, kaya need m ito to regulate the V & I.
Kung yung battery m is 12V, the charge controller is also 12V.
Current rating = Power output of Panels / Voltage = 125 W / 12V = 10.4 A
So choose a Charge Controller of 12 V and more than 10.4 A.
Last one and pinka importante..
INVERTER, obviously need m ito, to convert DC power to AC power.
Gaya ng sinabi ko sa simula.. need na output power nito ay equal or more than sa Power load mo.
Halimbawa: TV =50W, Fan=25W, Lights=75W (TOTAL=150Watts)
So need m ng equal or more than 150Watts.. pde ka kumuha ng 200 Watts Inverter.
Let say, 12V yung system m, we have to select a 12V DC to 230V/50Hz AC pure sine wave inverter.

By the way I'm not EE.
I'm ECE & nag build na kami neto before.
Thanks.
