Solar System Sizing and ROI Calculator


There are many things to take into consideration when calculating the best size system for your home or business. The best size system will usually depend on your expectations. At Commercial Utility Solutions we prefer to take a personalised approach with our customers. We understand the importance of asking a variety of questions to ensure the system we recommend has the best chance of meeting your expectations.

In saying that, the following calculator will guide you to a generalisation of a system size that should be approximately appropriate for you. It is partially personalised as it takes your location and usage habits into consideration, however there are also many generalisations which is why we strongly encourage you to contact us for a discussion prior to making any decisions. There may also be options suitable for you that the calculator does not accommodate for, such as a battery solution.
