Sizing Matters

Residential System Design Guide

The average home consumes around 18-20 kw of electricity per day, a large family home in some cases will consume around 25-30 kw or more per day.

       

To get an idea of what size system would suit your home have a look at a recent power bill and check your average daily usage (kw per day) this can be found next to the bar graph that shows your monthly usage.

We recommend to install a system that will produce above your average daily requirements this will allow for the low production days in winter, we also recommend to think about the future requirements of the home as a smaller system  may impact your savings in years to come.

INSTALLING A SOLAR SYSTEM ON YOUR HOME WILL SAVE YOU MONEY AND REDUCE YOUR CARBON FOOTPRINT

The exact impact solar will have on your power bills depends on factors like

  • System size and efficiency

  • Your energy usage patterns

  • Energy rates charged by your electricity retailer

At Geelong Solar Energy we have extensive experience in reading power bills its something we do every day and when we quote we can size the system to your power usage to deliver you the best return on your investment.​

We also highly recommend going big and by installing the largest size residential system available you will future proof your home against rising power bills and lock in the rights to have the maximum size solar generation system on your property.

Consult with us and we will assess your specific situation and tailor a system to suit your needs.
