Is HOMER Pro A Free Software?

Although the trial version of this software is free of cost, it only gives you a maximum of 21 days to use without paying anything.

This software will cost you 65 USD per month.

This is why I like the computer tools for solar and renewable energy systems because most of them offer a free trial. It allows us to explore and learn more about their design tools. After a limited time, you will have an experience of how to use their software then you could decide whether to purchase it or not after the trial period.

Here are other renewable energy tools that offer a limited-time trial offer.

Will HOMER Pro Work On Mac?

Although HOMER Pro only works with Windows operating system, there are still ways to make it work on a MAC device using Virtual Machines.

In computing, a virtual machine (VM) is the virtualization/emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination.
