Solar Power Solution Enhances Reliability and Growth for Church in Lagos
Pastor Peter Adewale, 45 years old, started planting a church in the Ikorodu suburb of Lagos State in 2018. Over six years, the church grew from just 12 initial members to a stable congregation of 80 to 120 people. The church holds Sunday services, along with Bible study sessions on Wednesday and Friday evenings, each lasting about two hours.
However, power supply has been a persistent issue for the church. The electricity grid in Ikorodu is unreliable, providing power only 6 to 9 hours per day, with frequent, unpredictable outages.
Sunday mornings, in particular, often experience power cuts, disrupting the worship atmosphere. The church had initially used a petrol generator as a backup, but the high cost of fuel, frequent breakdowns, and noise pollution made this solution unsustainable. The power problems started to impact the church’s growth and overall operations.
Power Consumption and System Design
The church’s core electrical devices include the sound system, lighting, cooling units, and auxiliary electronics. During the Sunday service, the peak power consumption is approximately 2.5 kWh, with an estimated total monthly consumption of 21.5 kWh. Based on these requirements, the proposed system is as follows:
| Equipment | Power (W) | Operating Hours (h) | Power Consumption (kWh) |
|---|---|---|---|
| Sound System | 190 | 3 | 0.57 |
| Lighting | 220 | 3 | 0.66 |
| Cooling Equipment | 450 | 3 | 1.35 |
| Auxiliary Equipment | 295 | 3 | 0.89 |
| Total (Sunday Service) | — | — | 2.5 |
The total weekly power consumption is approximately 3.3 kWh, with Sunday services using 2.5 kWh. On non-service days (Bible study and youth fellowship), the power consumption is lower, around 0.4 kWh per event, with a total monthly consumption of about 21.5 kWh.
To meet the church's energy needs, a solar power system consisting of four lithium batteries and five 300W solar panels is recommended. The system's total storage capacity is 5.12 kWh, which is more than sufficient to support the power demands of weekly services, with an additional 50% capacity reserved for future growth.
The five solar panels, providing a combined power of 1500W, are expected to generate between 6-7.5 kWh per day—well beyond the church's daily power consumption.
For efficient battery charging, the PowMr HHJ60-PRO 60A MPPT charge controller handles the conversion. It supports a maximum input of 3200W, ensuring optimal solar energy utilization and system stability.
To convert the DC power to AC, a 2500W power inverter is used. This inverter can easily handle the church's maximum load of 1155W. Its surge capacity of up to 7000W allows it to manage short-term power spikes during equipment startups, ensuring that the system operates efficiently under varying load conditions.

System Benefits
- Efficient Solar Generation: The solar system employs MPPT technology, which maximizes solar energy utilization even under suboptimal sunlight conditions, ensuring reliable and efficient energy generation for the church.
- Sufficient Power Supply: With a storage capacity of 5.12 kWh, the system fully meets the power needs for weekly services, while the solar system generates 6-7.5 kWh daily, providing ample energy surplus. This also ensures that the system can operate even during cloudy days.
- Environmentally Friendly and Quiet Operation: Solar energy is a clean, renewable resource, meaning the church’s activities now run on environmentally friendly power. Unlike noisy, polluting gasoline generators, the solar system operates silently, enhancing the worship experience and creating a more peaceful environment for the congregation.
Changes After Installation
After installing the solar system, the church saw a significant improvement in its operations. Services and events no longer suffer from power interruptions. A recent wedding and Bible study session continued smoothly despite power outages in the area, and the congregation was impressed by the reliability of the system.
Moreover, fuel costs were drastically reduced, and the savings were redirected into community charity projects, fostering a sense of belonging and participation among the congregation. The number of young people returning to the church also increased significantly, with attendance numbers rising.
Conclusion
This solar power system provides stable and clean electricity, solving the church's ongoing power issues. The system's high efficiency, long lifespan, and energy savings have greatly reduced the church's reliance on fuel-based generators, while also enhancing the atmosphere of worship and the sense of community among the congregation. As the church grows, the system can be easily expanded to meet increasing energy demands.
