Find the Right Solar Energy Products for Your Home or Business
A residential or commercial solar system includes three main components: solar panels with mounting frames, a solar inverter, and the necessary cables, switches, and monitoring equipment. For those aiming for complete energy independence with an “off-grid” setup, a solar battery is essential.

Solar Panels
Solar panels come in a range of quality and price options, and while their performance differences are minimal, there are key distinctions in how their energy output degrades over their lifetime and the length of their warranty coverage.
Solar Inverters
In the field of solar technology, two main types of inverters dominate: string inverters and micro-inverters. String inverters, about the size of a printer, are the component most likely to experience potential failure within the first 10-15 years of use.
Solar Batteries
Residential solar batteries store excess energy from solar panels, enhancing energy independence, providing backup during outages, reducing grid reliance, optimising energy usage, and contributing to financial savings.
Solar Monitoring
Inverters usually have built-in monitoring capabilities straight out of the box. However, to gain more detailed insights into the energy flow to and from the grid, you’ll need an additional device called a consumption monitor.

Steve & Jackie - Richmond
Steve & Jackie were looking for local solar specialists with experience installing in Melbourne’s densely packed inner suburbs. We had to overcome some design challenges due limited space, the orientation of the panels, and shading from trees and neighbouring buildings.
