Homeowners looking to add battery to Solar System can benefit from reviewing their existing solar equipment before choosing a new battery. Solar panels typically generate electricity during daylight hours, while many households continue using substantial amounts of electricity during the evening. Battery storage provides a way to retain some excess solar generation for later use, potentially increasing the amount of solar electricity consumed within the property. Nepean Solar can consider the existing solar panels, inverter, electricity consumption, battery capacity requirements and electrical infrastructure when assessing an upgrade. Compatibility is an important consideration, particularly for older solar systems that may use equipment with different specifications from newer battery technology. The installation may also require additional electrical work, depending on the property's existing switchboard and the chosen battery configuration. Customers can consider whether they want the battery primarily for increased solar self-consumption, reducing grid electricity purchases, or backup power, as these objectives can influence system design. The Australian Government recommends assessing battery costs and benefits according to individual circumstances because battery storage is not necessarily the right financial choice for every property. A professional assessment can help homeowners understand the practical requirements before committing to a battery upgrade.
