Abstract: In this paper, a case study is presented where a residential solar system in Kitchener, Ontario is analysed economically as its annual performance is also assessed. The recorded data for this system are investigated further to better assess its technical performance. Optimal annual performance is observed when the temperature is at 18°C and when the wind speed is at 3.8 m/s. The modelled system without the battery correlates closely with the actual installed system. In fact, the actual return on investment (ROI) for the system is 19.75% while the modelled ROI is 23.5%. The payback time of 5 years is another major highlight of this system. Finally, the greenhouse gas (GHG) emissions of the current system total up to 38,000 kgCO₂e/kWh.

Keywords: solar energy; photovoltaics; thermoeconomics; battery storage; performance assessment; cost analysis.
