Residential Solar + Battery Storage in Alamo

At this Alamo home, Synergy Power’s project brings rooftop solar and battery storage together in one residential energy system. The project pairs 34 Hyundai solar panels with Enphase microinverters and four Enphase IQ Battery 10C units, providing 40 kWh of storage.

Project Scope: Solar + Battery Storage

• Location: Alamo, California
• Project type: Residential solar + energy storage
• Solar array: 34 Hyundai HiN-T440NF(BK) 440W panels
• Solar capacity: 14.96 kW DC
• Microinverters: 34 Enphase IQ8HC-72-M-DOM-US [240V] microinverters
• Battery storage: Four Enphase IQBATTERY-10C-1P-NA 10 kWh batteries; 40 kWh total
• Meter collar: One Enphase IQ Meter Collar MC-200-011-V01
• Roof type: Metal
• Estimated annual solar production: 22,032 kWh

Solar and Storage, Working Together

Hyundai panels generate electricity on the home’s metal roof, while Enphase microinverters convert the solar power for household use. Four Enphase IQ Battery 10C units add storage to the system, giving the home a way to keep solar energy for later use.

Projected Financial Benefits

• Return on investment: 200.02%
• Payback period: 9.2 years
• Estimated annual utility savings: $7,104
• Utility savings over 20 years: $246,873

Financial and energy production figures are estimates from the project proposal. Savings depend on the proposal’s utility rate assumptions and actual system performance.
