Key Features

Solar power panels need the sun’s light so they only generate electricity during the day, so it’s most economical to install a system that can supply your expected daytime electricity usage. Our smallest solar power system needs just 10 sqm of roof space to generate around 30% of the average Australian household’s energy use. The more power you would like to generate the bigger the roof space you will need.

The ABB UNO 4.2 inverter is well suited for most small to medium sized rooftop installations. This inverter has the option of running on either one or two strings. This is particularly useful for rooftop installations with two different orientations, e.g. East and West.

Our extensive network of Seilar Experts are qualified to assess your home and provide you with the best systems to meet your family’s needs. Our installers are trained to the highest standards to ensure the safety and effectiveness of your system. All this is backed by our comprehensive warranties and the peace of mind you’ll get from dealing with Australia’s solar pioneer.

  •  Trouble Free – designed and engineered for Aussie conditions
  •  Independently rated as one of the highest performing panels.
  •  Transformerless Technology
  •  With connection for laptop or datalogger

* The suggested price is comprised of RRP less the applicable solar incentive and excluding installation. the solar incentive value applies to PVR4080A42 solar power system in Zone 3.

^ Energy savings of up to 5600 kWh/year is based on the average amount energy produced per year by the PVR4080A42 solar power system in Zone 3. Savings and incentives will vary depending upon your location, type of Seilar system installed, orientation and inclination of the solar panels.
