Air Conditioner (Window Unit): 1500W (Note: Air conditioners can vary significantly based on size and type)

2. Calculate Daily Watt-hour Usage:

Estimate the average daily usage hours for each appliance, especially air conditioners during the hottest parts of the day.

For Example:

Refrigerator (300W) x 24 hours/day = 7200 Wh/day
Air Conditioner (1500W) x 4 hours/day (assuming use during peak heat) = 6000 Wh/day

3. Add Up Your Appliance Wh Needs:

Total all the Wh figures from your appliances to determine your household’s daily Wh consumption.

4. Factor in Derating and Sunlight Hours:

Derating refers to the reduction in solar panel efficiency due to factors like heat and dust. A typical derating factor in the Philippines might be 1.2.
Multiply your daily Wh consumption by the derating factor (e.g., sum of your appliance Wh + Air Conditioner Wh).
Research the average sunlight hours per day in your Philippine location.

5. Calculate Your Required KW System Size:

Divide your total daily Wh consumption (after derating) by the average sunlight hours in your area. This will give you the total kW capacity required for your system.

For Example:

Let’s say your total daily Wh consumption after derating, including the air conditioner, is 15,000 Wh, and your location averages 5 sunlight hours a day.
Divide 15,000 Wh by 5 hours/day = 3000 W. Convert Watts (W) to Kilowatts (kW) by dividing by 1000 (3000 W / 1000) = 3 kW.

Remember: This is a simplified example. A professional solar installer can conduct a more precise assessment considering factors like your specific appliance usage patterns, air conditioner size and efficiency, and future plans.
