How To Get 24-Hours Electricity in Nigeria
Estimating Your Energy Needs
To calculate the amount of solar power needed for 24-hour electricity in Nigeria, you’ll need to determine your daily energy consumption. Here’s a step-by-step guide:
- List Your Appliances: Identify all the electrical appliances you use in your home or office.
- Calculate Daily Usage: Multiply the power rating (in watts) of each appliance by the number of hours you use them daily.
- Sum Up the Total: Add the daily usage of all appliances to get your total daily energy consumption in watt-hours (Wh).
Example Calculation for a Household
| Appliance | Power Rating (Watts) | Hours Used Per Day | Daily Consumption (Wh) |
|---|---|---|---|
| Refrigerator | 150 | 24 | 3,600 |
| TV | 100 | 6 | 600 |
| Light Bulbs (5) | 60 each | 5 | 1,500 |
| Fan | 75 | 10 | 750 |
| Laptop | 50 | 8 | 400 |
| Total | 6,850 |
For this example, the total daily energy consumption is 6,850 Wh or 6.85 kWh.
Sizing Your Solar System
To ensure continuous power, consider the following factors:
- Peak Sun Hours: Nigeria averages about 5 peak sun hours per day.
- System Efficiency: Account for efficiency losses (typically around 20%).
Solar Panel Calculation
Daily Energy Consumption (kWh)÷Peak Sun Hours=Required Solar Panel Capacity (kW)
For our example:
6.85 kWh ÷ 5 hours = 1.37 kW
Considering efficiency losses:
1.37 kW ÷ 0.80 = 1.71 kW
You would need a 1.71 kW solar system to meet the daily energy needs.
Cost Estimation
Using the prices from the guide:
Cost=1.71 kW × ₦200,000 per kW = ₦342,000
Note: This is a basic estimate and actual costs can vary based on the type of panels, installation costs, and other factors.
Conclusion
Solar energy is a viable and sustainable solution for Nigeria’s energy challenges. Investing in solar panels can provide reliable power, significant cost savings, and environmental benefits. By understanding the different types of solar panels, their specifications, and the factors affecting their prices, you can make an informed decision that meets your energy needs and budget. With proper installation and maintenance, solar panels can serve as a long-term, efficient power source for your home or business.
