OpenSolar vs SolarEdge Go

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.

SolarEdge Go is a free mobile app for installers managing photovoltaic sites and fleets and providing remote services. It brings together work from SetApp, Mapper and Monitoring, although full Mapper integration is described as future support. Installers can sync with SolarEdge Cloud, import designs, view site details and alerts, manage users, and create or edit sites. Site tools also include applying SolarEdge Designer plans, registering or replacing devices, and managing access permissions. The app supports on-site device configuration and registration, plus map-based fleet views, site details and responses to critical issues. Remote access supports inverter and system diagnostics and configuration, but is beta, requires administrator permissions, and is limited to supported SetApp-enabled leader inverters with CPU version 4.13 or higher. Sessions last up to 15 minutes. Full functionality requires internet access and a SolarEdge Cloud connection; without internet, use is limited to local commissioning through a direct inverter connection. Android 11 or higher and iOS 14 or higher are required. The app is for installers, not homeowners, and requires SolarEdge account credentials.
