System Type
When is solar most worth it for you?
Solar delivers the highest return on investment if
Ideal Roof Orientation
You have an unshaded roof facing South, East, or West, allowing your solar panels to capture more sunlight and generate energy efficiently throughout the day.
Maximise Daytime Solar Use
You run heavy appliances during daytime hours or charge an EV at home, allowing you to use more of the solar energy your system generates and reduce reliance on grid electricity.
MCS-Certified Installation
You pair your solar panels with an MCS certified installation, helping ensure recognised quality standards while giving you access to competitive export tariffs for any surplus energy sent back to the grid.
