Our licensed solar engineers are here to help analyze your interval meter data and recommend the right setup.
Most businesses offset between 60% and 80% of daytime grid electricity outgoings. By utilizing daytime generation during peak operating hours and avoiding peak kW demand charges, systems achieve a full payback period typically under 4 years.
Typical Australian homes require 12 kWh to 25 kWh of usable battery storage. A 13.5 kWh battery bank stores excess daytime solar generation to power air conditioning, lighting, and cooking through evening peak rate hours.
A standard grid-connected system shuts down during a blackout for safety. With a battery and backup gateway configured, essential circuits or the whole home switch over in under 20 milliseconds and keep running on stored energy.
A standalone power system combines an oversized array, a large storage bank and an auto-start backup generator. We size it against your worst-case winter week so the generator rarely runs, and add remote monitoring for fault alerts.
We do. SEBSS lodges the network pre-approval with your distributor, manages the connection paperwork, and applies the federal STC rebate as an upfront discount so it comes off your invoice rather than being claimed later.
Tier-1 panels carry a 25-year performance warranty, inverters 5 to 10 years depending on model, and batteries a 10-year warranty. Our workmanship is warranted separately, and servicing is handled by our own local team.
