Choosing a battery solar system for home use involves considering how much electricity the household generates, consumes and exports throughout the day. Solar panels can produce excess electricity during periods of strong sunlight, while a battery can store some of that energy for later use when solar generation is lower. Nepean Solar can help homeowners assess their existing or proposed solar system and determine what battery capacity and configuration may be appropriate for their household. Important considerations can include daily electricity consumption, the timing of energy use, solar generation, inverter capacity, available battery location and existing electrical infrastructure. A battery can also be configured to provide backup power during a grid outage, although this requires appropriate equipment and installation and may only provide power to selected circuits depending on the system design. Homeowners should also consider battery warranty conditions, expected lifespan, safety requirements and the overall cost of the installation when comparing options. Eligible small-scale battery systems may qualify for current Australian Government support through the Cheaper Home Batteries Program, subject to the applicable requirements. By assessing the property and its actual electricity-use patterns, Nepean Solar can help homeowners explore battery storage as part of a complete residential energy solution.
