OpenSolar vs SolarProjeX

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.

SolarProjeX is a web, Android, iOS, and API system for solar contractors, covering work from leads and quotes through permitting, installation, service, and warranty claims. It supports photovoltaic projects as well as solar pool heating and hot water, including a SunProjeX connector for signed thermal proposals. Field teams can use scheduling and dispatch, a live technician map, a mobile app, GPS-tagged photos, and custom forms with required-photo checks. The system handles invoices, on-site card payments, and emailed Stripe payment links, with payment status recorded on each job. Homeowners get a branded portal for equipment, documents, warranties, receipts, appointments, service history, and live production. All plans include the same features, but user and storage allowances differ; extra users and storage are priced separately. Plans start at $149/mo, and a 7-day trial is available. There is no free plan.
