Welcome to OS 2.6.0

We’ve heard your feedback and are excited to share what we’ve recently built with your help.

This release includes some serious design and proposal tool polish like enhanced heatmaps, 3D designs for custom or uploaded imagery, easily shareable proposal links and more to make that next deal just a bit easier to get out the door and close.

We hope you enjoy these updates and are able to make use of them as best fits your business!

Save time and simplify your design considerations with our enhanced heatmaps feature. Enjoy our enhanced colour scheme which now shows the actual shading impact of nearby objects in the 3D imagery, like trees, and lets you see how much sun every square inch of the property gets with just the click of a button. Both the loading time and quality of the sun access assessment are significantly improved so you can create even more efficient solar designs and layouts in less time.

Please check our help center for a tour of this new and improved feature.

Get proposals in front of your customers quicker with shareable proposal links. You can now easily copy the proposal link and paste it into an email or text so you can share proposals faster, simplify the solar shopping experience, and increase the odds that your proposal is viewed almost immediately after being sent.

Please check our help center for a tour of this new feature.

You can now overcome inadequate imagery due to new construction, spotty coverage, or anything else and get all the benefits of OpenSolar’s 3D modeling engine on custom or uploaded imagery. Just pull the new imagery straight into your design and create an accurate, realistic 3D proposal for the projects that need that extra bit of effort.

Our horizon shading feature makes it easy to upload your horizon files (.hor file type) and model the shading impacts of far away objects (e.g. mountains) on your solar array. Create accurate and thorough designs for your customers so that you can be confident in the production values and savings estimates.

You asked, we listened. OpenSolar now supports accurately modeling microinverters that connect to multiple panels (e.g. 2:1 or 4:1). Forget the workarounds and create more accurate designs and proposals for your customers in less time.

Please see this article to see how the Number of MPPTs field is now used for multi-panel micro inverters.

Other Enhancements

There are a wide range of other improvements for your use, available now. See the full release notes for more information.

Our team continues to work hard to ensure that you have the tools you need to sell solar as efficiently as possible, and we are continually listening to your insights for ways we can improve the app even further. We always appreciate the constructive feedback that you provide. If you ever have any questions, please contact us at

Have a sunny day,


Product Designer, OpenSolar
