This proposal details a comprehensive and scalable energy storage solution designed for modern homeowners. Our system empowers households to achieve greater energy independence, significantly reduce electricity costs, and build resilience against increasing power outages. By seamlessly integrating with new or existing solar panel installations, this solution unlocks the full potential of solar energy, transforming how families power their lives.Based on our calculations of factors like daily sunlight hours, we recommend a 5kWh solar power system configuration consisting of: one 5kWh battery, one 6.2kW inverter, and two 610W solar panels.
