Introduction: Get the Right Solar System for Your Home
Choosing a solar system for your home in Pakistan can be tricky. If it is too small, your bills will still be high. If it is too big, you waste money.
The key is to size it correctly.
This guide gives you a simple, step-by-step plan. We will help you figure out exactly what your home needs.
Step 1: Find Your Average Monthly Electricity Bill
This is the easiest and most important step. Your electricity bill already tells you how much power you use.
- Action: Look at your last 6 to 12 electricity bills.
- Find: The “Units Consumed” or “KWh Used” (Kilowatt-hours).
- Calculate: Add up the units for all months and divide by the number of months. This gives you your average monthly consumption.
- Example: If you use 500 KWh in summer and 300 KWh in winter, your average might be 400 KWh per month.
Step 2: Convert Monthly Units to Daily Need
Solar systems are sized by how much power they produce each day.
- Calculation: Divide your average monthly units by 30 (days in a month).
- Example: 400 KWh / 30 days = 13.3 KWh per day.
- This means your home needs about 13.3 units of electricity per day.
Step 3: Calculate Total Panel Wattage Needed
Now we figure out how many solar panels you need.
- Sunshine Hours: In most parts of Pakistan, you get about 4-5 “peak sun hours” per day on average. Let’s use 4.5 hours for this example.
- Calculation: (Daily KWh needed / Peak Sun Hours) = System Size in KW.
- Example: 13.3 KWh / 4.5 hours = 2.95 KW system.
- This means you need a system that can produce 2.95 Kilowatts (KW) of power at its peak.
- Panel Wattage: Most modern panels are 550W or 580W.
- If you use 550W panels: 2.95 KW = 2950 Watts.
- 2950 Watts / 550 Watts per panel = 5.36 panels.
- Round up: You would need 6 solar panels (550W each) for a 3 KW system.
Step 4: Choose Your Inverter Size
The inverter converts solar power into usable home electricity. Its size should match your panel array and your home’s peak power needs.
- Inverter Size (KW): This should be close to your total panel wattage.
- Peak Load: Also, consider your highest power usage at one time. If you run 2 ACs at once (e.g., 3000 Watts), your inverter must be able to handle that.
Step 5: Decide on Battery Storage (Hybrid Systems)
Do you want power during load shedding or at night? Then you need solar batteries. This makes it a Hybrid System.
- Identify Critical Loads: What must run during power cuts? (Fans, lights, fridge, 1 AC?)
- Battery Size (KWh): Calculate how many units these items use for a few hours.
- Example: If your critical loads use 5 KWh over 4 hours of load shedding, you might need a 5-10 KWh lithium battery.
