Pylon Observer is best choice for an Aurora Solar alternative.
When comparing Pylon Observer to Aurora Solar, you will find all of the powerful features that you get with a premium solar design software like Aurora, but you only pay per project instead of per month. This eliminates costly overheads.
Add an unlimited number of users to your team for no additional fees and give them high resolution aerial imagery, 3D shading analysis, job installer sheets and more.
Apart from Pylon's No Monthly Fees, a major difference between Pylon and Aurora Solar is that Pylon has a 2D design surface that allows for 3D objects to be placed and modelled. This means that the design surface doesn't move along numerous axes, but you still get the precision of 3D shade modelling. A flat design surface is easier to use on tablets and desktops. Some users who switch from Aurora Solar to Pylon Observer claiming their design times have been cut by up to 50%.
