This is definitely the best place to buy solar panels, storage batteries and energy-efficient heaters. Amazing service and great value.
We had a ten-panel domestic installation. The price was competitive, the installers and electricians were excellent, all up and running in a couple of days, friendly and helpful service through out.
Callidus were extremely professional from start to finish with the installation at our unit. Dealing with their team was a pleasure.
These guys were great, no pushy sales, just a great solution that works really well. We have batteries and solar from them, and it’s saved us a fortune on our electricity bills, with great advice on how to make the most of our dual rate tariff. Their technical knowledge is second to non.
The entire team at Callidus, from the top to the bottom, are amazing. Knowledge, support, passion to place the customer and their needs at the centre of the process, throughout all phases. Clear explanations with realistic expectations; no over inflated figures to close out a deal. I am so satisfied with their approach that I have already completed an expansion of my system; NOT because it didn’t perform as promised, but in fact we are generating more than expected so have increased the battery storage!! I am now looking to see if they can provide a windmill option to harness the overnight wind potential :)
