Builder Porter Davis is offering free Tesla batteries and solar panels to new homes as part of a deal with power company Bradford Energy.

The two companies will equip 50 new knockdown rebuild homes in Victoria with 5.6 kilowatt solar panels and Tesla Powerwall 2 home battery packs as a standard inclusion.

Bradford Energy forecasts an average consumer energy saving of $2600 a year and the possibility of reaching 90 per cent energy self-sufficiency with the new battery installations.

“Porter Davis’ knockdown rebuild homes equipped with Tesla technology will also see reductions in carbon emissions of up to 9500 kilograms per year,” the company said in a statement.
