Instead of OpenSolar

OpenSolar alternatives

OpenSolar brings solar design, sales, and project administration into one free platform. Ada AI can generate multiple system designs based on preferences; customizable branded proposals, flexible payments, invoices, online payments, and e-signatures support customer transactions. Equipment ordering and bills of materials are part of the design experience, while its API connects project, design, pricing, hardware, and contact data with other tools. Site surveys, design handoff, crew scheduling, and service visit tracking extend its workflow beyond the sale.

An alternative may fit better when field execution, installation-stage approvals, fleet monitoring, or enterprise project operations are the priority. OpenSolar supports Android, iOS, macOS, web, and API access, while some options focus on mobile or field teams and Solar ERP is web-only. OpenSolar Pro is free; API Access has a 30-day trial, then a geo-specific per-project fee. Before switching, consider which project stages matter, whether crews need offline mobile work, what integrations are useful, and whether paid plans fit your needs.
