Solar + storage
Generating by Day. Storing for Later.
The rooftop array provides daytime renewable generation while six GoodWe LFP battery modules allow excess solar energy to be stored for later use.
The GoodWe ESA hybrid inverter forms the central interface between the solar array, battery storage, household loads and electricity grid. With 48 kWh of usable storage, the system was designed to increase onsite use of solar energy outside peak production hours.
Project boundary: Blackout backup capability is not claimed because the available project records do not confirm that backup was commissioned.
Modelled energy outcome
Designed for Greater Energy Independence
The proposal modelling indicated that solar generation and substantial storage could reduce annual grid electricity costs to approximately zero under the assumptions used.
