Commercial Solar Prices


Lower Your Costs

We have modelled three example system sizes that have been based on typical commercial rooftop installations. All customer enquiries are treated on an individual basis and will receive their own costed benefits example.

The above models have been based upon installation to a metal roof at 5 degrees pitch with an azimuth of 35 degrees from the south. All scaffold, labour and access requirements have been included. The systems are designed using the most appropriate inverters for the best features, monitoring and overall value.
