Editorial verdict

How to choose between them

Aurora is the design standard that added Sales Mode. OpenSolar is the free platform that added design to a CRM.

If lender diligence and change-order risk scare you, Aurora’s shade reports and Premium modeling are the clearer public story. If software cost and tool sprawl scare you, OpenSolar’s free core — design, proposal, finance paths, CRM, and project stages — is the clearer public story.

Neither gives you native WhatsApp. Neither is a plant-monitoring O&M suite. Aurora expects a CRM beside it more often than OpenSolar does; OpenSolar’s own API pages still admit teams that keep Salesforce. Pick the pain: accuracy seats or stack cost.
