System Sizes by Property Type
Typical solar system configurations for different landed property types in Singapore.
| Property Type | System Size | Panels | Monthly Savings | Payback |
|---|---|---|---|---|
| Terrace House | 6-8 kW | 15-20 | S$150-250/month | 5-7 years |
| Semi-Detached | 8-12 kW | 20-30 | S$250-400/month | 5-7 years |
| Bungalow | 10-15 kW | 25-40 | S$350-600/month | 5-8 years |
| Good Class Bungalow | 15-20 kW | 40-50 | S$500-900/month | 6-8 years |
Roof Types & Solar Suitability
Different roof types require different mounting approaches. We assess your roof during our free site survey.
Pitched Roof
ExcellentThe most common roof type in Singapore. Panels are mounted on rails parallel to the roof surface. Optimal for drainage and panel angle.
Flat Roof
Very GoodCommon on modern bungalows and some semi-Ds. Requires tilted mounting structures to achieve optimal angle (10-15°).
Hip Roof
Very GoodMulti-faceted roof with slopes on all sides. Panels can be installed on multiple faces to capture morning and afternoon sun.
Gable Roof
GoodTriangular roof with two sloping sides. East-west facing gables can have panels on both sides for extended generation.
Metal Roof
GoodCommon on older properties and extensions. Requires specialized clamping systems. Lightweight and durable.
Key Considerations
Important factors when designing solar for landed properties.
Roof Space
A typical 10kW system requires ~50-60 sqm of roof space. We assess available area, obstructions, and optimal layout during site survey.
Shading Analysis
Nearby trees, buildings, and structures can reduce output. We use shading analysis tools to optimize panel placement and recommend solutions.
Aesthetic Integration
For premium properties, we offer all-black panels, hidden conduit routing, and low-profile mounting to maintain property aesthetics.
Battery Storage
Landed homes with high evening usage benefit from battery storage. Store excess daytime solar for use at night, maximizing self-consumption.
Landed Property Solar FAQs
Terrace houses typically need 6-8kW, semi-Ds 8-12kW, and bungalows 10-15kW. The exact size depends on your roof space, electricity usage, and budget. Use our estimator for a precise calculation.
