Summary: Discover how to calculate the ideal solar panel size for rooftops in Kumasi, Ghana. This guide explores local solar potential, system design considerations, and real-world installation examples to help residential and commercial users harness clean energy effectively.

Why Kumasi''s Sunshine Demands Smart Solar Sizing

With 1,800+ annual sunshine hours, Kumasi ranks among West Africa''s prime locations for rooftop photovoltaics. But here''s the catch: oversized panels waste money, while undersized systems can''t meet energy needs. Let''s break down the sweet spot.

Key Factors Affecting Panel Dimensions

  • Roof orientation: South-facing roofs capture 15% more energy
  • Daily consumption: Average Kumasi household uses 8-12 kWh/day
  • Panel efficiency: MonoPERC modules achieve 21% conversion rates
"Most clients underestimate shadow patterns from neighboring buildings. We always recommend 3D modeling before installation." - Solar Engineer, Ghana Energy Commission

Real-World Installation Data (2023)

Building TypePanel Size (kW)Annual Output
Residential Bungalow3.55,200 kWh
Commercial Store7.210,800 kWh
School Complex1522,500 kWh

Pro Tip: The 70-30 Rule

Install panels to cover 70% of daytime consumption while leaving 30% roof space for future expansion. This balances upfront costs with evolving energy needs.

5-Step Sizing Formula for Kumasi Homes

  1. Calculate daily kWh usage from utility bills
  2. Multiply by 1.3 (compensate for system losses)
  3. Divide by 4.2 (average daily peak sun hours)
  4. Multiply by 1,000 to convert to watts
  5. Add 15% buffer for appliance upgrades

Example: 10 kWh/day × 1.3 = 13 → 13 ÷ 4.2 ≈ 3.1 kW → 3.1 × 1.15 = 3.56 kW system

FAQs: Solar Sizing in Kumasi

What''s the average cost per watt?
