Solar energy systems in Douala require robust battery solutions to combat frequent power outages and maximize renewable energy potential. This guide explores battery technologies, local challenges, and actionable insights for homes and businesses.

Why Battery Storage Matters for Solar Systems in Douala

Douala's tropical climate offers 4.5–5.5 kWh/m² daily solar irradiance, but grid instability affects 72% of businesses. Batteries solve three critical problems:

• Backup power during 8–12 hour monthly outages
• Energy time-shifting for peak sunlight hours
• Reduction in diesel generator dependency (saves 40–60% fuel costs)
