Installing Solar PV (Photovoltaics) is paramount for achieving high EPC ratings (B and A) as it dramatically reduces a property's purchased electricity and subsequent carbon intensity. A standard domestic 4kWp system, designed and installed by Smart Energi Hub, directly improves the SAP calculation score, which determines the EPC band. We specialize in integrating high-efficiency PV arrays with Battery Storage systems (typically 5kWh to 10kWh). This integration allows properties to engage in peak shaving—storing cheap solar energy for use during expensive evening peak times or leveraging Time-of-Use tariffs—which maximizes financial returns and drives self-sufficiency beyond simple daytime generation.
