Article 4: How to Size Your Solar Power System – Step-by-Step Guide

Introduction

Before installing a solar power system, you must know how much energy you need. Proper sizing ensures that your system produces enough electricity without wasting money on extra components.

Let’s walk through the steps to calculate the right solar system size for your needs.

Step 1: Calculate Your Daily Energy Consumption

Check your electricity bill or list your appliances.

Example Table:

Appliance Power (Watts) Hours/Day Daily Consumption (Wh)

LED Lights (5x) 50W total 5 hrs 250 Wh
TV 100W 4 hrs 400 Wh
Fridge 150W avg 24 hrs 1200 Wh
Laptop 60W 3 hrs 180 Wh

Total Daily Use = 250 + 400 + 1200 + 180 = 2,030 Wh (or 2.03 kWh)

Step 2: Add Energy Losses

No system is 100% efficient. Add 20–30% to cover inverter losses, wiring, weather, etc.

> 2.03 kWh × 1.3 = 2.64 kWh/day

Step 3: Determine Solar Panel Output in Your Area

Check average sunlight hours per day. Example:

Egypt = ~5.5 hours/day

UK = ~3.5 hours/day

Now divide your daily need by peak sun hours:

> 2.64 ÷ 5.5 = ~0.48 kW = 480 Watts

You’d need around 500W of panels, but better to oversize by 20–30%, so go for:

> 600–700W total solar panel capacity

Step 4: Size Your Battery (if needed)

For off-grid or hybrid systems:

> Battery Capacity = Daily Usage × Days of Backup ÷ Depth of Discharg

Example:

> 2.64 kWh × 2 days ÷ 0.8 = ~6.6 kWh battery bank

Step 5: Select Inverter Size

Your inverter should be slightly above your peak power load.
If your max load is 1000W, choose at least a 1.5 kW inverter.

Conclusion

Sizing your solar system correctly is the foundation of a successful installation. Always calculate carefully—or consult a professional—before buying components.
