Daily Solar Energy Output in Surabaya: Trends & Data Analysis
Harnessing Sunlight in Indonesia's Solar Hub
Surabaya, Indonesia's second-largest city, has become a testbed for photovoltaic innovation in tropical climates. With average daily solar radiation of 4.8-5.2 kWh/m², this coastal metropolis offers unique opportunities for renewable energy adoption. Let's explore how photovoltaic panels perform here and what it means for urban energy solutions.
Key Performance Metrics (2023 Data)
| System Size | Daily Output | Annual Yield |
|---|---|---|
| 5kW Residential | 18-22 kWh | 6,570-8,030 kWh |
| 100kW Commercial | 360-440 kWh | 131,400-160,600 kWh |
Why Surabaya's Climate Matters
While abundant sunshine boosts production, local conditions present unique challenges:
- High humidity (avg. 75-85%) affecting panel efficiency
- Frequent rain showers requiring smart energy storage
- Urban heat island effect increasing nighttime demand
Case Study: Tunjungan Plaza Installation
This shopping mall's 1.2MW solar array demonstrates practical results:
- Peak daily generation: 5,100 kWh
- 30% reduction in grid dependency
- 4.2-year ROI achieved through net metering
Government Initiatives Driving Adoption
Indonesia's EBTKE 2025 program has accelerated solar adoption through:
- Tax incentives covering 30% of installation costs
- Simplified permitting for <50kW systems
- Feed-in tariffs of $0.12/kWh for excess energy
Residential vs. Commercial Adoption Rates
Market data reveals distinct patterns:
- Homes: 72% choose 3-5kW systems
- Hotels: Average 120kW installations
- Factories: 500kW+ systems becoming common
Frequently Asked Questions
What's the optimal panel angle in Surabaya?
Most installers recommend 10-15° tilt to balance energy production and self-cleaning from rainfall.
How does monsoon season affect output?
December-February sees 18-25% lower production, but modern systems compensate through improved low-light performance.
