How to Choose the Right Solar Panel Size for Your Energy Needs in Nigeria
Switching to solar power is a smart investment for any Nigerian home or business — but to truly enjoy the benefits, you must choose the right solar panel size. The wrong size can mean wasted money, underpowered systems, or overspending on unnecessary capacity.
At Arise Energies, we help customers find the perfect solar solution tailored to their power needs, location, and budget. In this guide, you’ll learn exactly how to determine the ideal solar panel size for your property.
Why Solar Panel Size Matters
The size (or capacity) of your solar panel system determines:
-
How much power you generate daily
-
How quickly your batteries charge
-
How much you save on electricity bills
-
How long your appliances can run without public power or generators
A correctly sized system ensures you get the best performance at the lowest cost.
Step 1: Calculate Your Energy Consumption
Start by listing all the appliances and devices you want to power, along with their wattage. Multiply each appliance’s wattage by the number of hours it runs daily.
Example:
Appliance | Wattage | Hours Used Daily | Total Wh/Day |
---|---|---|---|
TV | 100 W | 5 hrs | 500 Wh |
Refrigerator | 200 W | 10 hrs | 2,000 Wh |
LED Bulbs (10) | 10 W | 6 hrs | 600 Wh |
Total: 3,100 Wh or 3.1 kWh/day |
Step 2: Factor in Sunlight Hours
Nigeria gets 4–6 hours of peak sunlight daily, depending on the region. To find the panel size you need:
Formula:
From our example:
You’ll need at least two 350W panels or equivalent.
Step 3: Consider Efficiency & System Losses
No system is 100% efficient. Dust, wiring, and temperature can reduce performance by 10–20%. Add a 20% buffer to your capacity calculation to ensure reliability.
Adjusted Capacity:
This means going for 800W total panel capacity would be ideal.
Step 4: Plan for Future Growth
If you plan to add more appliances or expand your business, size your system slightly bigger now to avoid costly upgrades later.
Step 5: Consult a Professional
While these calculations give you a starting point, a professional assessment from Arise Energies ensures:
-
Accurate sizing
-
Quality product selection
-
Proper installation for maximum output
Common Mistakes to Avoid
-
Undersizing your system – leads to frequent power shortages.
-
Oversizing unnecessarily – wastes money on extra capacity you don’t use.
-
Ignoring battery storage – your panels need the right battery size to store generated power effectively.
