2. Conduct a Site Inspection

A professional inspection evaluates:

• Roof condition
• Available space
• Structural strength

In Lagos and coastal regions, buildings must withstand humidity and corrosion factors.

3. Evaluate Sunlight Exposure

Solar panels require optimal sunlight.

Key checks include:

• Roof orientation (south-facing is ideal)
• Shading from trees or nearby buildings
• Seasonal sunlight variations

Homes in high-density areas like Ikoyi and Lekki should pay special attention to shading.

4. Choose the Right Solar System Type

Select a system based on your needs:

• Grid-tied systems
• Hybrid systems
• Off-grid systems

For urban Nigeria, hybrid systems are often preferred due to grid instability.
