OpenSolar vs SolarSAAS

OpenSolar is a platform for solar professionals to design, sell, and manage projects. Its Ada AI can create multiple system designs in seconds based on design preferences. Users can prepare customizable, branded proposals with flexible payments and real-time updates, then manage invoices, payment milestones, reminders, online payments, and e-signatures. Equipment ordering is built into the design experience, and the hardware catalogue can produce a bill of materials. An API connects project, design, pricing, hardware, and contact data with CRM, accounting, operations, and incentive tools. OpenSolar Pro costs nothing; the listing also notes a free plan and a 30-day trial. API Access is a paid add-on with a 30-day free trial; its geo-specific fee applies when a project is created, with billing starting at the beginning of the closest month after the trial. OpenSolar lists Android, iOS, macOS, web, and API access. It says stored and transmitted data are encrypted and targets 99.95% service availability.
