Start with kWp, not a promised output
Solar system capacity is commonly expressed in kilowatt-peak, or kWp. It describes the rated capacity of the panels under defined test conditions, not a guaranteed amount of electricity every day.
A preliminary estimate then considers usable roof area, panel layout and expected operating conditions.
What affects generation
Roof orientation, tilt, shading, panel temperature, soiling, inverter efficiency, cable losses and equipment condition all influence output. Singapore's changing weather means daily production naturally varies.
Two properties with similar panel capacity can therefore produce different results.
Use an estimate to plan questions
Solar Calculator can help organise an initial estimate using available project information. Treat the result as a planning aid rather than a savings promise or quotation.
A site assessment and professional system design are needed to validate roof suitability, layout, electrical requirements and expected performance.
