Pre Installation

Plug 1 Electrical is using the latest technology to visualise your roof space before any quotation, this allows for proper design of the PV System considering roof space, orientation, shading issues and the electrical switchboard onsite. It’s advisable that you also have an electricity bill on hand so we can view your daily consumption to assess your needs.


Typically installation on homes will generally take a day to complete. We require the homeowner to be there on the day of installation for access, government incentive documentation and meter alteration paperwork. The property will be left spic and span as all Rubbish and excess materials we be taken with us.


On completion we will give you a full run through on the systems operation and provide you with an informative response on any final questions you may have. Post installation there will be an Independent electrical inspection where the installation will be signed off and all the required paperwork will be submitted to your electricity retailer for the meter alteration.

Choosing your solar size

To work out the right solar system capacity for you consider:

  • - how much electricity you use
  • - how many people live in your home
  • - your roof size, its orientation and shade
  • - your budget

For best value, aim for a system size which covers a third to half your daily electricity usage. The table below provides estimates to help you consider what size system will work for you. You can then assess if the sunlight available on your rooftop – and your budget – can accommodate your preferred system size. Our recommended solar company can help with this.
